ListView Listener not Working
|
<p>I've seen a few examples on here to this problem, but none have solved this issue, observe the code below:</p>
<pre><code>mProductList = hotdealhelper.getCatalog(getResources());
ListView myListView = (ListView) findViewById(R.id.listViewoffers);
myListView.setAdapter(new hotdealadapter(mProductList, getLayoutInflater()));
myListView.setOnItemClickListener(new OnItemClickListener() {
public void onItemClick(AdapterView<?> parent, View view, int position,
long id) {
System.out.println("Newbie");
}});
</code></pre>
<p>I have it in my oncreate lethod, and when I click on a particular position in the list, it is not printing the system.out. I am wondering why this is, I have used this exact code in another class and it works fine. I have the list in a activity class also. Below is the xml if it helps.</p>
<blockquote>
<p>
<pre><code><ImageView android:id="@+id/imageView1" android:src="@drawable/dealheader" android:layout_width="match_parent" android:layout_height="wrap_content" android:layout_alignParentTop="true"></ImageView>
<ListView android:layout_height="wrap_content" android:id="@+id/listViewoffers" android:layout_width="match_parent" android:layout_marginTop="35px"></ListView>
<Button android:text="Button" android:id="@+id/button1" android:layout_width="match_parent" android:layout_height="wrap_content" android:layout_marginBottom="0px" android:layout_alignParentBottom="true"></Button>
</code></pre>

java.util.Date cannot be cast to Object[]
|
<p>I'm using java reflection to call methods at runtime. How do I cast a date object into an object array?</p>
<p>ie,</p>
<pre><code>Method m = ....;
Object[] result = (Object[]) m.invoke(...);
public Date getDate() {
return new Date();
}
</code></pre>
<p>Would give:</p>
<pre><code>java.lang.ClassCastException: java.util.Date cannot be cast to [Ljava.lang.Object;
</code></pre>
<p><strong>Edit</strong>: yeah, I should just add it to an Object array instead and return it.</p>

How to Pass Class Variables in a Function Parameter
|
<p>The main function of the example class uses the reusableFunction twice with different data and attempts to send that data to a different instance variable ($this->result1container and $this->result2container) in each case, but the data doesn't get into the instance variables.</p>
<p>I could get it to work by making reusableFunction into two different functions, one with array_push($this->result1container, $resultdata) and the other with array_push($this->result2container, $resultdata), but I am trying to find a solution that doesn't require me to duplicate the code.</p>
<p>My solution was to try to pass the name of the result container into the function, but no go. Does somebody know a way I could get this to work?</p>
<p>Example Code:</p>
<pre><code>Class Example {
private $result1container = array();
private $result2container = array();
function __construct() {
;
}
function main($data1, $data2) {
$this->reusableFunction($data1, $this->result1container);
$this->reusableFunction($data2, $this->result2container);
}
function reusableFunction($data, $resultcontainer) {
$resultdata = $data + 17;
// PROBLEM HERE - $resultcontainer is apparently not equal to
// $this->result1container or $this->result2container when I
// try to pass them in through the parameter.
array_push($resultcontainer, $resultdata);
}
function getResults() {
return array(
"Container 1" => $this->result1container,
"Container 2" => $this->result2container);
}
}
</code></pre>
<p>(If this is a duplicate of a question, I apologize and will happily learn the answer from that question if somebody would be kind enough to point me there. My research didn't turn up any answers, but this might just be because I didn't know the right question to be searching for)</p>

Red undelines on some devices with android:inputType="textEmailAddress|textEmailSubject"
|
<p>I am using android:inputType="textEmailAddress|textEmailSubject" on some fields to prevent long lines from wrapping per a suggestion on a post here on Stackoverflow. However I just noticed that on my Nexus-S (but not the Samsung Tab-2 7) some of the text is underlined in red.</p>
<p>For example "18 BR" has the BR undelined. But "NAS2" is not underlined. "TI" is underlined. If I remove the android:inputType="textEmailAddress|textEmailSubject" then the underlines go away but the lines can wrap with long user names.</p>
<pre><code><!-- Readout Waypoint Name -->
<TextView
android:inputType="textEmailAddress|textEmailSubject"
android:id="@+id/textWaypoint"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentBottom="true"
android:layout_centerHorizontal="true"
android:text="--"
android:textAppearance="?android:attr/textAppearanceLarge"
android:textSize="@dimen/menu" />
</code></pre>
<p>What is the best way to solve this. I can find nothing in Google or on Stackoverflow and have no idea what the best way to solve it is.</p>

Explicit specialization of non-class, non-function members of a class template
|
<p>Look at the code:</p>
<pre><code>template <class x> struct Foo
{
int getX(x *p) { return(0); }
enum E12 { a };
};
template <> int Foo<int>::getX(int*)
{
return(-15);
}
template <> enum Foo<int>::E12
{
a, b, c
}
</code></pre>
<p>As it was discussed in <a href="http://stackoverflow.com/questions/11268535/cannot-overload-function">Cannot overload function</a>, the first specialization is legal and even works in MSVC. While the second specialization for <code>enum</code> does not even want to compile, saying "error C2988: unrecognizable template declaration/definition".</p>
<p>It seems to me that C++ is making relaitively unlogical exception for methods. Enum is just an example. The same thing can be applied to member classes, typedefs, etc.</p>
<p>I will be happy is some body will comment on this.</p>

How to Prevent Date Objects from Wrapping in IE
|
<p>I am writing a form validator that needs to combine the values of three fields/drop downs into a string and check that string to see if it is a valid date. Currently, I am doing this by combining the values into a string of the form mm/dd/yyyy and running that string through a comparison:</p>
<pre><code>// Value is a string like mm/dd/yyyy
var date = new Date(value);
if( !date_regex.test(value) || date.toString() == 'Invalid Date' ) {
errors[element] = "Please provide a valid date";
}
</code></pre>
<p>This works fine in almost every case. In IE8, if the string is formed such that the month or day exceed the allowance for the given component, the date wraps them instead of marking the date as invalid. Examples:</p>
<pre><code>string: 03//2011
should be valid: no
is valid: no
Date.toString(): Invalid Date
correct: yes
string: 03/10/2011
should be valid: yes
is valid: yes
Date.toString(): Wed Mar 10 00:00:00 PST 2010
correct: yes
string: 03/40/2011
should be valid: no
is valid: yes
Date.toString(): Fri Apr 9 00:00:00 PST 2010
correct: no
string: 20/05/2011
should be valid: no
is valid: yes
Date.toString(): Fri Aug 5 00:00:00 PST 2010
correct: no
</code></pre>
<p>I've tried using Date.parse(value) and checking for NaN, but the date wraps the timestamp, too.</p>
<p>Any ideas on how to get IE to behave like the others?</p>
<p>Thanks much</p>

In app purchase not fully working

<p>I just wrote a test application to test in app purchases, it's just a test application where you have to press a button and you purchase a "premium" membership that will make that button invisible (this is just a test app)</p>
<p>So after my friend pressed the button he got the payment screen, he paid, but when he got back to the app the button was still there</p>
<p>This is how i start the purchase </p>
<pre><code> // User clicked the "Upgrade to Premium" button.
public void onUpgradeAppButtonClicked(View arg0) {
Log.d(TAG, "Upgrade button clicked; launching purchase flow for upgrade.");
// setWaitScreen(true);
mHelper.launchPurchaseFlow(this, SKU_PREMIUM, RC_REQUEST, mPurchaseFinishedListener);
}
</code></pre>
<p>and when the purchase is finished</p>
<pre><code>// Callback for when a purchase is finished
IabHelper.OnIabPurchaseFinishedListener mPurchaseFinishedListener = new IabHelper.OnIabPurchaseFinishedListener() {
public void onIabPurchaseFinished(IabResult result, Purchase purchase) {
Log.d(TAG, "Purchase finished: " + result + ", purchase: " + purchase);

// Oh noes!
// complain("Error purchasing: " + result);
// setWaitScreen(false);

Toast.makeText(getBaseContext(), "You are now premium", duration).show();
Button test = (Button) findViewById(R.id.test);
test.setVisibility(View.INVISIBLE);
// updateUi();
// setWaitScreen(false);
}
}

Extending LatinIME
|
<p>I want to extend android's default IME, LatinIME. I cloned LatinIME's Android 2.1 tag from here (<a href="http://android.git.kernel.org/?p=platform/packages/inputmethods/LatinIME.git;a=summary" rel="nofollow">http://android.git.kernel.org/?p=platform/packages/inputmethods/LatinIME.git;a=summary</a>), but there are some issues with the code... </p>
<p>For example in the class <code>CandidateView</code> the variable <code>mScrollX</code> is used, which is part of <code>View</code>, the extended class. But turns out that with the public SDK, that variable is private so it can't be used by children classes.</p>
<p>What I found in Google to be the solution to this is to change the use of <code>mScrollX</code> for the public getters of <code>View</code>, but the code also sets that variable and there are no setters available.</p>
<p>Another issue is that <code>com.android.internal.R</code> is used, which also isn't public available.</p>
<p>How am I supposed to extend LatinIME? Have anyone tried to do something like this?</p>
<p>Thanks in advance.</p>

correct use of iterator to return an object from a list

<p>I'm still learning c++ so would be happy to understand what i'm doing wrong. Also,</p>
<ul>
<li>Is it good practice to return a reference to an object from a function ? Is there something better to do ?</li>

Create a byte array according to given String In Java
|
<p>I just need to create a byte array out of the given String.</p>
<p>For example, if my String is <code>String ss = "21331UA";</code> then the byte array elements should correspond to them as follows.</p>
<pre><code>2 1 3 3 1 U A
</code></pre>
<p>I could have created it statically as this. <code>byte[] arr = new byte[]{2,1,3,3,1,'U','A'}</code> But have to create this byte array in the runtime dyanamically as this changes time to time. Thats the problem.</p>
<p>I just tried as follows and print them, it contains their corresponding ASCII values.<strong>This is not what I want.</strong></p>
<pre><code>byte[] arr = ss.getBytes();
for(int i=0; i<arr.length; i++)
{
System.out.print(arr[i] + " ");
}
Ans==> 50 49 51 51 49 85 65

Slowly Draw A Line In Android
|
<p>I have a Line class composed of two Points of two ints each that I draw with a wrapper over Canvas.drawLine(). </p>
<p>Easy so far. </p>
<p>I <em>want</em> to have that Line drawn slowly from one Point to the other. My best guess is to make a function that will dice up my Line into an list of Lines, starting from the first Point with each subsequent Line getting longer and longer till it reaches from one Point to the other. Then, I will have a Canvas.drawLine wrapper that will take that array of Lines, and iterate over them, drawing each one with a pause of some sort in between them, giving the appearance of the line "growing".</p>
<p>Is there something in the android libraries that already does this and/or would this be better solved some other way?</p>
<p><strong>Edit: This is android 2.1</strong></p>

Python - Efficiently building a dictionary

<p>I am trying to build a dict(dict(dict())) out of multiple files, which are stored in different numbered directories, i.e. </p>
<pre><code>/data/server01/datafile01.dat
/data/server01/datafile02.dat
...
/data/server02/datafile01.dat
/data/server02/datafile02.dat
...
/data/server86/datafile01.dat
...
/data/server86/datafile99.dat
</code></pre>
<p>I have a couple problems at the moment:</p>
<ol>
<li>Switching between directories </li>
</ol>
<p>I know that I have 86 servers, but the number of files per server may vary. I am using:</p>
<pre><code>for i in range(1,86):
basedir='/data/server%02d' % i
for file in glob.glob(basedir+'*.dat'):
Do reading and sorting here
</code></pre>
<p>but I cant seem to switch between the directories properly. It just sits in the first one and gets stuck it seems when there are no files in the directory</p>
<ol>
<li>Checking if key already exists</li>
</ol>
<p>I would like to have a function that somehow checks if a key is already present or not, and in case it isnt creates that key and certain subkeys, since one cant define dict[Key1][Subkey1][Subsubkey1]=value</p>

Passing reference on every method call or once on instance creation
|
<p>I'm making a simple game, and it has a single instance of a class named <code>Game</code> that deals with all the logic of the game. </p>
<p>Many of the classes in the project have a method called <code>tick()</code> which is called from within the <code>Game</code> instance 60 times per second and deals with updating information. Such instances are stored in list(s) in the <code>Game</code> class.</p>
<p>This method requires access to the <code>Game</code> class and currently looks like this:</p>
<pre><code>MyClass {
public void tick(Game game) {
...
}
}
</code></pre>
<p>My question is - would it be <em>better</em> to do as I am doing now and pass a reference hundreds and thousands of times per second to all the instances that require it or simply pass a single reference to these instances on creation and have the classes look like so:</p>
<pre><code>MyClass {
private Game game;
public MyClass(Game game) { this.game = game }
public void tick() { ... }
}
</code></pre>
<p>Basically, how taxing it is to pass this reference so many times every second?</p>
<p>Thanks in advance.</p>
<p><strong>Edit:</strong>
Perhaps another option is to mark all the required members of the <code>Game</code> class as static and calling them as such without a reference at all?..</p>

Using JavaScript to read files stored on a user's computer
|
<p>I'm building a website which has a music player that can currently play files stored on the server. I'm using soundManager2 to play the files. </p>
<p>What I would like to do is have the player also play files stored on a user's computer, which may not be possible and will probably hit security risks if it is.</p>
<p>This is a bit of the code I use to plays the files:</p>
<pre><code>currentTrack = soundManager.createSound({
id: "Track",
url: file_location+".mp3",
});
</code></pre>
<p>Then soundManager2 does its magic. As the location of the file is a variable, I was hoping that if a user were to specify the location of an mp3 on their computer it could be put into the variable and played in soundManager, in the same way it finds files on our server and plays them. My thinking is that as soundManager uses javascript and flash, or HTML5 it's all client side so there wouldn't be any security issues and it could just be 'streamed' from their computer without any strain on our bandwidth.</p>
<p>How can this be done?</p>

Android - getting the dimensions of a view in order to position it
|
<p>I've got a tiled pan-n-zoom component that uses several FrameLayouts to position image tiles (that scale), markers (that move, but don't scale) and controls (which neither move nor scale). It works fine.</p>
<p>Markers are positioned in a FrameLayout with topMargin and leftMargin. So far so good.</p>
<p>When a marker is touched, I need to open a little popup, at the same position as the marker that was touched <em>but offset by the dimensions of the popup</em>. That's to say that if the popup is 100 pixels wide and 50 pixels tall, and the marker touched was at 800 x and 1100 y, the popup should be at 750 x (postion of marker minus half the width of the popup) and 1050 y (position of the marker minus the full height of the popup). The effect is like a tooltip - a little nub points down at the marker, etc.</p>
<p>The popup dimensions are flexible, based on the text to be displayed, and need to be calculated.</p>
<p>Obviously the dimensions aren't available until after layout happens. What's the best way to get these dimensions and react accordingly?</p>
<p>(should mention that a RelativeLayout is not an option)</p>
<p>TYIA.</p>
<p>/EDIT
looks like I can get the dimensions of the children in onMeasure and onLayout, but re-applying a new layout in one of these handlers would create an infinite loop - setting a flag to catch just the first pass did not work. i guess the updated question would be "now that I know where I can get the information, how should I react and position it?"</p>

Console.Read is being ignored
|
<p>I'm new to the C# language, and have only started learning it for use on the XNA Game Studio for X-box.</p>
<p>I have some minor experience with Java and C++, so I'm not a TOTAL noob. That's exactly why this problem is so frustrating to me.</p>
<p>I have created a simple code designed to add two numbers input from the user. Extremely simple stuff, but a good first step for any new language I feel.</p>
<p>I've declared my variables, and was trying to use Console.Read() to get numbers from the user to add. So far, the code outputs the message I want, then stops and reads in a single input from the user. After that, it messes up. The console outputs the next message, reads some random number (no input), then adds them together and outputs that instantly.</p>
<p>Here is my code:</p>
<pre><code>using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
namespace Add
{
class Program
{
static void Main(string[] args)
{
Console.WriteLine("Please enter the first number to add: ");
int firstNumber = Console.Read();
Console.WriteLine("Please enter the second number to add: ");
int secondNumber = Console.Read();
int Sum = firstNumber + secondNumber;
Console.WriteLine("The total of the two numbers is: " + Sum);
}
}
}
</code></pre>
<p>Sample runs:</p>
<p>Please enter the first number to add:</p>
<p>2</p>
<p>Please enter the second number to add:</p>
<p>The total of the two numbers is: 63</p>
<hr>
<p>Please enter the first number to add:</p>
<p>3</p>
<p>Please enter the second number to add:</p>
<p>The total of the two numbers is: 64</p>
<hr>
<p>It continues like that, acting as though the secondNumber is 61.</p>

<p>So how would I. Run two of these on one page, I am on iPad so difficult to set styling on here, etc. So apologies.</p>
<p>Basically the above code accompanies HTML and CSS to display hover effect on a advert div, we have all divs working correctly individually but because we have no I'd for the functions, they don't work together correctly when we have more than one on a page. As you can see I am crap at js.</p>

Changing the theme of an android app using preferences
|
<p>I have been trying to get my app to read data from the preferences, and change the theme according to the option selected. I have found many different suggestions on the internet, including here, but have been unable to get it to work.</p>
<p>I have created preferences.xml and arrays.xml, and the user is able to select the theme they want. However, the change is not reflected in the app.</p>
<p>Here are the contents of ActivityMain.java:</p>
<pre><code>public class MainActivity extends Activity {
protected void onCreate(Bundle savedInstanceState) {
SharedPreferences preferences = PreferenceManager.getDefaultSharedPreferences(this);
String userTheme = preferences.getString("prefTheme", "darkab");
if (userTheme.equals("darkab"))
setTheme(R.style.darkab);
else if (userTheme.equals("light"))
setTheme(R.style.light);
else if (userTheme.equals("dark"))
setTheme(R.style.dark);
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
}
@SuppressLint("NewApi")
protected void onResume(Bundle savedInstanceState) {
recreate();
SharedPreferences preferences = PreferenceManager.getDefaultSharedPreferences(this);
String userTheme = preferences.getString("prefTheme", "darkab");
if (userTheme.equals("darkab"))
setTheme(R.style.darkab);
else if (userTheme.equals("light"))
setTheme(R.style.light);
else {setTheme(R.style.dark);}
super.onResume();
setContentView(R.layout.activity_main);
}
</code></pre>
<p>These are the styles I wish to use, as set in styles.xml:</p>
<pre><code><style name="darkab" parent="android:Theme.Holo.Light.DarkActionBar"></style>
<style name="light" parent="android:Theme.Holo.Light"></style>
<style name="dark" parent="android:Theme.Holo">
</code></pre>
<p>And here is my preferences.java file:</p>
<pre><code>public class Preferences extends PreferenceActivity {
@SuppressWarnings("deprecation")
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
addPreferencesFromResource(R.xml.preferences);
}
</code></pre>

Setting image based on user selection?
|
<p>I have an activity where the user can select their character. I have three image buttons on the screen and when the user clicks the character they want, I want the game to load another activity that will then just show an image of the character they selected in the previous screen. Basically this is just the forerunner for what I am going to do later. I found some examples on this website for how to accomplish this but I haven't quite gotten it all ironed out.</p>
<p>This is what I have in my character selection activity:</p>
<pre><code>Button archerButton = (Button) findViewById(R.id.Button_Archer);
archerButton.setOnClickListener(new View.OnClickListener() {
public void onClick(View v) {
Intent intent = new Intent(SelectCharacterActivity.this, LevelOneActivity.class);
intent.putExtra("@drawable/archer", pathToImage);
startActivity(intent);
finish();
}
});
</code></pre>
<p>The pathToImage line is throwing an error. What exactly am I supposed to put here?</p>
<p>The LevelOne activity which is supposed to just display the image chosen has this:</p>
<pre><code> public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_LANDSCAPE);
setContentView(R.layout.level_one);
String path = getIntent().getStringExtra("imagePath");
Drawable image = Drawable.createFromPath(path);
Character_Chosen.setImageDrawable(image);
}
</code></pre>
<p>I'm a bit confused on this section as well. The Character_Chosen entry is the name of the imageview which should house the selected image.</p>
<p>I'm also confused on this line of code:</p>
<pre><code>String path = getIntent().getStringExtra("imagePath");
</code></pre>
<p>Does this mean I have to manually enter the image path every time? What if they choose a different image?</p>
<p>Does anyone have a link to an actual working example? Pseudo code doesn't really help me very much when I'm a novice and don't know what needs to stay and what needs to go.</p>

<pre><code>$('a.someClass:hidden').bind('click', function(){
alert("test");
});
</code></pre>
<p>It seems the click event is not bound when these elements are no longer hidden. Has anyone experienced this? Is there a way to bind and event to elements irregardless of their display property?</p>
<p>Thanks</p>

asp:textbox displays question marks instead of Kanji/Japanese characters characters
|
<p>I have an aspx page which consumes a Siebel webservice and gets Kanji characters from Siebel on demand. This shows as a series of question marks in the aspx textbox. This cannot be a data error from the backend as the other applications get proper kanji characters from Siebel. Also, I have installed East Asian languages from control panel and added [ja-Jp] language under Languages tab of Internet Explorer 7. also, I have added
<strong>globalization requestEncoding="Shift-JIS" responseEncoding="Shift-JIS"</strong>
to my web.config and have also tried changing 'Shift-JIS' to 'utf-8' in the above line, but no difference. I have also saved my aspx page and its code-behind pages with Unicode (utf-8 with signature) encoding, but find no change in the characters displayed in the textbox.</p>
<p>Please help.</p>
