For right-to-left flow, start=right, end=left.

The &quot;start&quot; and &quot;end&quot; concepts were added in API Level 17, as part of [Android 4.2&#39;s support for RTL layouts][1].


  [1]: http://developer.android.com/about/versions/android-4.2.html#RTL

Android supports RTL layouts from API 17+ i.e., Android 4.2 (Jelly Bean).and when we make our layout to support both RTL and LTR then we can not use layout_marginleft and layout_marginRight there we use layout_marginstart and layout_maginend .

It&#39;s an helpful answer. I was thinking about it and reading documentation was unable to get the answer. So the margin left is margin start for English and similar languages

I am using Handlebar.js as my templating engine. Now I want to comment out some of the blocks in my handlebar templates. But then I realized that Handlebar doesn&#39;t ignore the expressions inside the Handlebar comment block. Any workaround for this?

How to use comments in Handlebar templates?

In this case

    struct Foo {};
    Foo meh() {
      return std::move(Foo());
    }

I&#39;m pretty sure that the move is unnecessary, because the newly created `Foo` will be an xvalue.

But what in cases like these?

    struct Foo {};
    Foo meh() {
      Foo foo;
      //do something, but knowing that foo can safely be disposed of
      //but does the compiler necessarily know it?
      //we may have references/pointers to foo. how could the compiler know?
      return std::move(foo); //so here the move is needed, right?
    }

There the move is needed, I suppose?

When should std::move be used on a function return value?

What is difference between Android margin start and right (or margin end and left)?

It is trivial question, but I cannot seem to learn from [the documention](http://developer.android.com/reference/android/view/ViewGroup.MarginLayoutParams.html) what is difference between view start/end and left/right. It could be that I just don&#39;t understand something, but I cannot make any progress with this at all.

I have been having this problem in an application I am building. Please ignore all of the design shortcomings and lack of best practice approaches, this is purely to show an example of what I cannot solve.

I have `DialogFragment` which returns a basic `AlertDialog` with a custom `View` set using `AlertDialog.Builder.setView()`. If this `View` has a specific size requirement, how do I get the `Dialog` to correctly resize itself to display all of the content in the custom `View`?

This is the example code I have been using:

    package com.test.test;
    
    import android.os.Bundle;
    import android.app.Activity;
    import android.app.AlertDialog;
    import android.app.Dialog;
    import android.app.DialogFragment;
    import android.content.Context;
    import android.graphics.Canvas;
    import android.graphics.Color;
    import android.graphics.Paint;
    import android.graphics.Paint.Style;
    import android.view.Gravity;
    import android.view.LayoutInflater;
    import android.view.View;
    import android.view.WindowManager;
    import android.view.View.OnClickListener;
    import android.view.ViewGroup;
    import android.view.ViewGroup.LayoutParams;
    import android.widget.ArrayAdapter;
    import android.widget.Button;
    import android.widget.EditText;
    import android.widget.FrameLayout;
    import android.widget.LinearLayout;
    import android.widget.Spinner;
    import android.widget.TextView;
    
    public class MainActivity extends Activity {
    	
    	@Override
    	protected void onCreate(Bundle savedInstanceState) {
    		super.onCreate(savedInstanceState);
    			
    		// Use a button for launching
    		Button b = new Button(this);
    		b.setText(&quot;Launch&quot;);
    		b.setOnClickListener(new OnClickListener() {	
    			@Override
    			public void onClick(View v) {
    				// Launch the dialog
    				myDialog d = new myDialog();
    				d.show(getFragmentManager(), null);
    			}
    		});
    		
    		setContentView(b);
    	}
    	
    	public static class myDialog extends DialogFragment {
    		
    		@Override
    		public Dialog onCreateDialog(Bundle savedInstanceState) {			
    			// Create the dialog
    			AlertDialog.Builder db = new AlertDialog.Builder(getActivity());
    			db.setTitle(&quot;Test Alert Dialog:&quot;);
    			db.setView(new myView(getActivity()));
    			
    			return db.create();
    		}
    		
    		protected class myView extends View {
    			Paint p = null;
    			
    			public myView(Context ct) {
    				super(ct);
    
    				// Setup paint for the drawing
    				p = new Paint();
    				p.setColor(Color.MAGENTA);
    				p.setStyle(Style.STROKE);
    				p.setStrokeWidth(10);
    			}
    			
    			@Override
    			protected void onMeasure(int widthMeasureSpec, int heightMeasureSpec) {
    				setMeasuredDimension(800, 300);
    			}
    			
    			@Override
    			protected void onDraw(Canvas canvas) {
    				// Draw a rectangle showing the bounds of the view
    				canvas.drawRect(0, 0, getMeasuredWidth(), getMeasuredHeight(), p);
    			}
    		}
    	}
    }

A `Button` is created, which opens the `DialogFragment` on a click. The custom `View` (`myView`) is required to have a width of 800 and height of 300 which is correctly set in an override of `onMeasure()`. This `View`, draws its measured bounds in magenta for debugging purposes.

The 800 width is wider than the default `Dialog` size on my device, but is clipped rather than stretching correctly.

I have looked through the following solutions:

 - https://stackoverflow.com/questions/8456143/dialogfragment-getdialog-returns-null
 - https://stackoverflow.com/questions/4406804/how-to-control-the-width-and-height-of-default-alert-dialog-in-android
 - https://stackoverflow.com/questions/8835931/size-of-alert-dialog-or-custom-alert-dialog

I have deduced the following two coding approaches:

 1. Get the `WindowManager.LayoutParams` of the `Dialog` and override them using `myDialog.getDialog().getWindow().get/setAttributes()`
 2. Using the `setLayout(w, h)` method through `myDialog.getDialog().getWindow().setLayout()`

I have tried them everywhere I can think of (overriding `onStart()`, in a `onShowListener`, after the `Dialog` is created and shown, etc) and can generally get both methods to work correctly if the `LayoutParams` are supplied a **specific value**. But whenever `WRAP_CONTENT` is supplied, nothing happens.

Any suggestions?

**EDIT:**

Screenshot of the situation:
![enter image description here][1]

Screenshot of a specific value (note 900 is entered here, 850 doesn&#39;t cover the entire width of the View, which makes sense given the entire window is being adjusted. So that provides - if another was needed - reason why `WRAP_CONTENT` is essential / fixed values are not appropriate):

AlertDialog with custom view: Resize to wrap the view&#39;s content

I created a new application in Eclipse, targeted to Jelly Bean. This is all automatically created code. The manifest sets the application theme to AppName:

	&lt;application
        android:allowBackup=&quot;true&quot;
        android:icon=&quot;@drawable/ic_launcher&quot;
        android:label=&quot;@string/app_name&quot;
        android:theme=&quot;@style/AppTheme&quot; &gt;
        . . . 
        
which translates to AppBaseTheme for styles in the values dir:

    &lt;resources xmlns:android=&quot;http://schemas.android.com/apk/res/android&quot;&gt;

        &lt;!--
            Base application theme, dependent on API level. This theme is replaced
            by AppBaseTheme from res/values-vXX/styles.xml on newer devices.
        --&gt;
        &lt;style name=&quot;AppBaseTheme&quot; parent=&quot;android:Theme.Light&quot;&gt;
            &lt;!--
                Theme customizations available in newer API levels can go in
                res/values-vXX/styles.xml, while customizations related to
                backward-compatibility can go here.
            --&gt;
        &lt;/style&gt;

        &lt;!-- Application theme. --&gt;
        &lt;style name=&quot;AppTheme&quot; parent=&quot;AppBaseTheme&quot;&gt;
            &lt;!-- All customizations that are NOT specific to a particular API-level can go here. --&gt;
        &lt;/style&gt;

    &lt;/resources&gt;

And values-v14/styles.xml is:

    &lt;resources&gt;

        &lt;!--
            Base application theme for API 14+. This theme completely replaces
            AppBaseTheme from BOTH res/values/styles.xml and
            res/values-v11/styles.xml on API 14+ devices.
        --&gt;
        &lt;style name=&quot;AppBaseTheme&quot; parent=&quot;android:Theme.Holo.Light.DarkActionBar&quot;&gt;
            &lt;!-- API 14 theme customizations can go here. --&gt;
        &lt;/style&gt;

    &lt;/resources&gt;

I then created a confirmation dialog box before quiting:

		case R.id.menu_quit:
			new AlertDialog.Builder(this)
			.setIcon(android.R.drawable.ic_dialog_alert)
			.setTitle(R.string.confirm_title)
			.setMessage(R.string.confirm_text)
			.setPositiveButton(R.string.ok, new DialogInterface.OnClickListener() {
				@Override
				public void onClick(DialogInterface dialog, int which) {
			        finish();    
				}

And the resulting dialog box is:

![resulting dialog box][1]

Why is the ic_dialog_icon so light? It is barely visible. I am using all defaults, I did not modify the theme or any colors, Shouldn&#39;t the system pick an icon wiht more contrast to its background? How can I fix it?

**Edit with fix**  
Following Tomik info I read the documentation for **android.R.attr.alertDialogIcon** and made this fix ( replaced **setIcon()** with **setIconAttribute()** )

			new AlertDialog.Builder(this)
			.setIconAttribute(android.R.attr.alertDialogIcon)
			.setTitle(R.string.confirm_title)
			.setMessage(R.string.confirm_text)
			.setPositiveButton(R.string.ok, new DialogInterface.OnClickListener() {

Now the dialog looks like this:

I have managed to get continuous speech recognition working (using the SpeechRecognizer class) as a service on all Android versions up to 4.1. My question concerns getting it working on versions 4.1 and 4.2 as it is known there is a problem in that the API doesn&#39;t do as documented in that a few seconds after voice recognition is started, if no voice input has been detected then it&#39;s as if the speech recogniser dies silently. (http://code.google.com/p/android/issues/detail?id=37883)

I have found a question which proposes a work-around to this problem (https://stackoverflow.com/questions/13670378/voice-recognition-stops-listening-after-a-few-seconds), but I am unsure as how to implement the Handler required for this solution. I am aware of the &#39;beep&#39; that will happen every few seconds that this workaround will cause, but getting continuous voice recognition is more important for me.

If anyone has any other alternative workarounds then I&#39;d like to hear those too.

Is there a way to programmatically find whether the device the app is installed on is a 7 inch tablet or a 10 inch tablet?

Detect 7 inch and 10 inch tablet programmatically

I got an `Activity` with two `Fragment`s (one list one normal). 
And the normal `Fragment` inflates a `Scrollview` containing a `LineaLayout` (vertical) and this layout contains `TextViews`.
The `ScrollView` and `layout_width` and `layout_height` are `match_parent`, so I think the whole screen should be used. But on the bottom there is still a &quot;gap&quot;.
I hope you can help me.
