**Try this**

    txtTest.setText( Html.fromHtml(&quot;&lt;a href=\&quot;http://www.google.com\&quot;&gt;Google&lt;/a&gt;&quot;));
    txtTest.setMovementMethod(LinkMovementMethod.getInstance());


**Remember :** don&#39;t use android:autoLink=&quot;web&quot; attribute with it. because it causes LinkMovementMethod doesn&#39;t work.

**Update for SDK 24+**
The function `Html.fromHtml` deprecated on `Android N` (SDK v24), so turn to use this method:

        String html = &quot;&lt;a href=\&quot;http://www.google.com\&quot;&gt;Google&lt;/a&gt;&quot;;
        Spanned result = HtmlCompat.fromHtml(html,Html.FROM_HTML_MODE_LEGACY);
        txtTest.setText(result);
        txtTest.setMovementMethod(LinkMovementMethod.getInstance());

**Here are the list of flags:**

    FROM_HTML_MODE_COMPACT = 63;
    FROM_HTML_MODE_LEGACY = 0;
    FROM_HTML_OPTION_USE_CSS_COLORS = 256;
    FROM_HTML_SEPARATOR_LINE_BREAK_BLOCKQUOTE = 32;
    FROM_HTML_SEPARATOR_LINE_BREAK_DIV = 16;
    FROM_HTML_SEPARATOR_LINE_BREAK_HEADING = 2;
    FROM_HTML_SEPARATOR_LINE_BREAK_LIST = 8;
    FROM_HTML_SEPARATOR_LINE_BREAK_LIST_ITEM = 4;
    FROM_HTML_SEPARATOR_LINE_BREAK_PARAGRAPH = 1;


**Update 2**
with `android.text.util.Linkify`, it&#39;s more easier now to make a clickable TextView:

    TextView textView =...
    Linkify.addLinks(textView, Linkify.WEB_URLS);

You can do it this way;

    mTextView = (TextView) findViewById(R.id.textView);
    String text = &quot;Visit my developer.android.com&quot;;
    mTextView.setText(text);
    // pattern we want to match and turn into a clickable link
    Pattern pattern = Pattern.compile(&quot;developer.android.com&quot;);
    // prefix our pattern with http://
    Linkify.addLinks(mTextView, pattern, &quot;http://&quot;)

Hope, this helps. Please see this [blog post][1] for details. (Its not mine, and I am not associated with it in anyway. Posted here for information purpose only).

I can&#39;t seem to Google it, but I want a function that does this:

Accept 3 arguments (or more, whatever):

 - URL 
 - a dictionary of params
 - POST or GET

Return me the results, and the response code.

Is there a snippet that does this?

Is there a more efficient way of doing this below? I want to have the difference in years between two dates as a single scalar. Any suggestions are welcome.

    from datetime import datetime
    start_date = datetime(2010,4,28,12,33)
    end_date = datetime(2010,5,5,23,14)
    difference  = end_date - start_date
    difference_in_years = (difference.days + difference.seconds/86400)/365.2425

I was wondering how I could play a notification sound without playing it over the media stream.  Right now I can do this via the media player, however I don&#39;t want it to play as a media file, I want it to play as a notification or alert or ringtone.  heres an example of what my code looks like right now:

    MediaPlayer mp = new MediaPlayer();
    mp.reset();
    mp.setDataSource(notificationsPath+ (String) apptSounds.getSelectedItem());
    mp.prepare();
    mp.start();

How to copy files from &#39;assets&#39; folder to sdcard?

I want to inflate a XML-Layout-File in a custom ViewGroup Class, my Problem is that it produces just a empty screen. Doing the same in the Activity Class works fine. 
Here is my simple XML-Layout-File: 

    shownumberlayout.xml:
        
        &lt;RelativeLayout 
        	xmlns:android=&quot;http://schemas.android.com/apk/res/android&quot;
        	android:layout_width=&quot;fill_parent&quot; 
        	android:layout_height=&quot;fill_parent&quot;
        	android:background=&quot;#FFFFFF&quot; 
        	android:id=&quot;@+id/layoutForNumber&quot;&gt;
        	
        	&lt;TextView 
        		android:layout_width=&quot;wrap_content&quot;
        		android:layout_height=&quot;wrap_content&quot; 
        		android:id=&quot;@+id/tvNumber&quot;
        		android:layout_centerHorizontal=&quot;true&quot; 
        		android:textColor=&quot;#000000&quot; 
        		android:text=&quot;Test&quot; 
        		android:layout_centerVertical=&quot;true&quot; 
        		android:textSize=&quot;30dip&quot;&gt;
        	&lt;/TextView&gt;
        
        &lt;/RelativeLayout&gt;

Here is the working Version, inflating the `shownumberlayout.xml` in the Activity `ShowNumber`:

    ShowNumber.class
    
    public class ShowNumber extends Activity {
        /** Called when the activity is first created. */
        	
    	@Override
        public void onCreate(Bundle savedInstanceState) {
            super.onCreate(savedInstanceState);
            LayoutInflater inflater = (LayoutInflater)getSystemService(Context.LAYOUT_INFLATER_SERVICE);
            ViewGroup vg = (ViewGroup) inflater.inflate(R.layout.shownumberlayout, null);
            setContentView(vg);
        }
    }

This shows a White Background with the black Text “Test” centered.

Now the Version inflating the xml in the Custom `ViewGroup`-Class:

    ViewGroup.class
    public class ViewNumber extends ViewGroup {
    	
    	private LayoutInflater inflater;
    	
    	public ViewNumber(Context context) {
    		super(context);
    		// TODO Auto-generated constructor stub
    		initView(context);
    	}
    
    	public ViewNumber(Context context, AttributeSet attrs) {
    		super(context, attrs);
    		// TODO Auto-generated constructor stub
    		initView(context);
    	}
    
    	public ViewNumber(Context context, AttributeSet attrs, int defStyle) {
    		super(context, attrs, defStyle);
    		// TODO Auto-generated constructor stub
    		initView(context);
    	}
    
    	private void initView(Context context){
    		inflater = (LayoutInflater)context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
    		inflater.inflate(R.layout.shownumberlayout, null);	
    	}
    
    	@Override
    	protected void onLayout(boolean changed, int l, int t, int r, int b) {
    		// TODO Auto-generated method stub
    	}
    
    }

    

    
ShowNumber.class
public class ShowNumber extends Activity {
    /** Called when the activity is first created. */
    	
	@Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        ViewGroup vg = new ViewNumber(this); 
        setContentView(vg);
    }
}

Im doing it basically like in [this][1] Answer explained.
This just produces a Empty Black Screen. What I am doing wrong?

**UPDATE 1**

**@Konstantin**
I applied your changes but still just a blank screen, i also made a log-ouput for getting the number of children. It remains always 1, even i add one more Textview to the XML-Layout-File. Before the Changes it remains always 0.

    public class ViewNumber extends RelativeLayout {
    ...
    private void initView(Context context){
    		//inflater = (LayoutInflater)context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
    		//inflater.inflate(R.layout.shownumberlayout, null);
    		View.inflate(context, R.layout.shownumberlayout,this); 
    		Log.v(&quot;ViewNumber&quot;, &quot;Number of Child: &quot; + this.getChildCount());//output is 1,before it remains 0
    	}
    ...
    }

**@Sankar** This is the Logcat, after the Changes from Konstantin:

**UPDATE 2**

The Content is finally showing correctly up.
The missing thing was to override the Method `onLayout` (thanks to **Franco**) in the RelativeLayout-Sublcass:

    public class ViewNumber extends RelativeLayout {
    ...
    
        @Override
                protected void onLayout(boolean changed, int l, int t, int r, int b) {
                    // TODO Auto-generated method stub
                    for(int i = 0 ; i &lt; getChildCount() ; i++){
                        getChildAt(i).layout(l, t, r, b);
                    }
                }
    ...
    }

Note: Later you should also override the Method `onMeasurement()`, but currently the content is also showing correctly without overriding it.

Now the solution for the Method `initView` from **Franco** do not align the TextView in the Center, but puts it in the top left corner. The solution from **Konstantin** puts it correctly in the Center of the View:

    public class ViewNumber extends RelativeLayout {
    ...
    private void initView(Context context){
            View.inflate(context, R.layout.shownumberlayout,this); 
        }
    ...
    }

I seem to recall most (maybe all) attributes in previously versions of HTML (before HTML5) required attributes to have values, like `readonly=&quot;readonly&quot;`.

is it autofocus=&quot;autofocus&quot; or autofocus?

In my table I set the width of the first cell in a column to be `100px`.&lt;br /&gt;

As part of internationalizing an Android application I have come across the need to dynamically word wrap or hyphenate at the right position.

All my strings are externalized in strings.xml files but I have not found any documentation about hyphenation in Android.

I would like to be able to suggest hyphenation positions similar to how I can do it in LaTeX:

http://en.wikipedia.org/wiki/Hyphenation_algorithm

But I have not found any indication if this is possible. Is there anything in the framework I have missed? What are other people doing e.g. with Japanese strings that have no obvious position to break up a sentence? Do you just add spaces at the correct positions?

I could dynamically size the font to fit into certain layouts but for longer messages that go across multiple lines that won&#39;t work. What to do?

How To Set Text In An EditText

In XML, we can set a text color by the `textColor` attribute, like `android:textColor=&quot;#FF0000&quot;`. But how do I change it by coding?

I tried something like:

    holder.text.setTextColor(R.color.Red);

Where `holder` is just a class and `text` is of type `TextView`. Red is an RGB value (#FF0000) set in strings.

But it shows a different color rather than red. What kind of parameter can we pass in setTextColor()? In documentation, it says `int`, but is it a resource reference value or anything else?
