Use the [`android:drawableLeft`][1] property on the EditText.

    &lt;EditText
		...		
		android:drawableLeft=&quot;@drawable/my_icon&quot; /&gt;

  [1]: http://developer.android.com/reference/android/widget/TextView.html#attr_android:drawableLeft

You can set drawableLeft in the XML as suggested by [marcos][1], but you might also want to set it programmatically - for example in response to an event. To do this use the method **[setCompoundDrawablesWithIntrincisBounds(int, int, int, int)][2]**:

    EditText editText = findViewById(R.id.myEditText);

    // Set drawables for left, top, right, and bottom - send 0 for nothing
    editTxt.setCompoundDrawablesWithIntrinsicBounds(R.drawable.myDrawable, 0, 0, 0);

If you want to use Android&#39;s default drawable, you can use `@android:drawable/ic_menu_search` like this:

    &lt;EditText android:id=&quot;@+id/inputSearch&quot;
        android:layout_width=&quot;fill_parent&quot;
        android:layout_height=&quot;wrap_content&quot;
        android:drawableLeft=&quot;@android:drawable/ic_menu_search&quot;
        android:hint=&quot;Search product..&quot;
        android:inputType=&quot;textVisiblePassword&quot;/&gt;

Use :

    &lt;EditText
        ..     
        android:drawableStart=&quot;@drawable/icon&quot; /&gt;


use [android:drawbleStart][1] propery on EditText
```xml
    &lt;EditText
        ...     
        android:drawableStart=&quot;@drawable/my_icon&quot; /&gt;
```

Use a relative layout and set the button the be align left of the edit text view, and set the left padding of your text view to the size of your button.  I can&#39;t think of a good way to do it without hard coding the padding :/

You can also use [apk tool][1] to sorta unzip the facebook apk and take a look at its layout files.

I&#39;m really not getting this, so if someone could explain how this works I&#39;d very much appreciate it. I have two applications, Accounts and Theme... here is my settings list:

    INSTALLED_APPS = (
        &#39;django.contrib.auth&#39;,
        &#39;django.contrib.contenttypes&#39;,
        &#39;django.contrib.sessions&#39;,
        &#39;django.contrib.messages&#39;,
    	&#39;accounts&#39;,
    	&#39;themes&#39;,
    )

In accounts, I am trying to do this:

    from themes.models import Theme
    
    class Account(models.Model):
    	ACTIVE_STATUS = 1
    	DEACTIVE_STATUS = 2
    	ARCHIVE_STATUS = 3
    	STATUS_CHOICES = (
    		(ACTIVE_STATUS, (&#39;Active&#39;)),
    		(DEACTIVE_STATUS, (&#39;Deactive&#39;)),
    		(ARCHIVE_STATUS, (&#39;Archived&#39;)),
    	)
    
    	id = models.AutoField(primary_key=True)
    	name = models.CharField(max_length=250)
    	slug = models.SlugField(unique=True, verbose_name=&#39;URL Slug&#39;)
    	status = models.IntegerField(choices=STATUS_CHOICES, default=ACTIVE_STATUS, max_length=1)
    	owner = models.ForeignKey(User)
    	enable_comments = models.BooleanField(default=True)
    	theme = models.ForeignKey(Theme)
    	date_created = models.DateTimeField(default=datetime.now)

And in my theme model:

 

    class Theme(models.Model):
    	id = models.AutoField(primary_key=True)
    	name = models.CharField(max_length=250)
    	slug = models.SlugField(unique=True, verbose_name=&#39;URL Slug&#39;)
    	date_created = models.DateTimeField(default=datetime.now)
    		
    class Stylesheet(models.Model):
    	id = models.AutoField(primary_key=True)
    	account = models.ForeignKey(Account)
    	date_created = models.DateTimeField(default=datetime.now)
    	content = models.TextField()

Django is kicking out the following error: 

    from themes.models import Theme
    ImportError: cannot import name Theme

Is this some kind of circular import issue? I&#39;ve tried using a lazy reference, but that doesn&#39;t seem to work either!

Apparently boost contains two separate libraries for state machines: [Statechart](http://www.boost.org/doc/libs/1_45_0/libs/statechart/doc/index.html) and [Meta State Machine](http://www.boost.org/doc/libs/1_45_0/libs/msm/doc/HTML/index.html) (MSM). The taglines give very similar descriptions:

* Boost.Statechart - Arbitrarily complex finite state machines can be implemented in easily readable and maintainable C++ code.
* Meta State Machine - A very high-performance library for expressive UML2 finite state machines.

Do you know what are the key differences and what are considerations in choosing between the two?

I want to turn off displaying &quot;Suggested Words&quot; on the soft/virtual keyboard when someone is using my application (only on certain `Activities`). For the default Android keyboard, this can be found under &#39;Settings&#39; (under Word Suggestion Settings).

Is there a way to disable it only within your application, without requiring the user to manually go and do it? I basically want the user to type words without providing any hints.

Thanks!

Now I am totally confused by this error message: **Android library projects cannot be launched.** 

I carefully checked the build path and library, everything seems &quot;OK&quot;, and there is no error on Problems view, however, when I tried to run my application as an Android project, it failed and showed that message.

Any explanation for why it&#39;s happening is appreciated!

I want to implement the `TextWatcher` interface for more than one `EditText` fields. Currently I am using :

    text1.addTextChangedListener(this);
    text2.addTextChangedListener(this);

then overriding the methods in my Activity:

   

    public void afterTextChanged(Editable s) {}
    
    public void beforeTextChanged(CharSequence s, int start, int count, int after) {}
    public void onTextChanged(CharSequence s, int start, int before, int count) 
    {
     // do some operation on text of text1 field
     // do some operation on text of text2 field 
    }




However this is working fine but I&#39;m looking for other ways so that I can explicitly identify that in which `EditText` field the `SoftKeyboard` is currently focused.

TextWatcher for more than one EditText

I am wondering if there are any good options to implement a **rich text editor** in Android. Please note I am talking about a rich text editor that can be used in an Android application, not the one embedded in a web page using HTML and Javascript.

My requirements are:

 - Basic formatting (color, fonts, highlight, bold, italic, underline, etc.)
 - Hyperlinks
 - Inline images
 - Bullet lists and numbered lists
 - Inline table (only the contents inside a cell is editable, not the table structure)

As you can see, this is pretty much something quite similar to a typical RichEdit control on Windows.

Here are some efforts (investigation &amp; prototyping) I have made so far:

Using WebView
-------------

I have tried using a WebView control to load an HTML fragment with one &lt;DIV contentEditable=&quot;true&quot;&gt;. The content becomes editable and as it is HTML, I suppose it can meet most of my requirements. But it has several issues:

 - (deadly) No text caret. The user will have no idea where his/her typed characters will be inserted.
 - The on-screen soft keyboard is not visible by default. There is a trick that the user has to long-press the Menu button to bring up the keyboard. But I think this is a very bad user experience. Besides, the screen layout is not properly rearranged and the text inserting point sometimes will be covered by the keyboard.

----------

Using EditText
--------------
I have tried using the EditText control. It seems to support some level of rich text editing (color, fonts, bold, italic, underline, inline images, bullet lists). But I still cannot figure out how I can implement the following requirements:

 - Control the appereance of the bullet symbol (dot, circle, dash, arrow, star, etc.)
 - Numbered list (1., 2., 3., etc.)
 - Table

BTW, I have seen there are several *Span classes out there but I am not sure if they can be any help... And the http://developer.android.com does not provide much useful information about them.

---

So, how on earth can I implement a rich text editor on Android?
Can I extends the EditText and add my new functionalities? Or should I do something from scratch - extends the View and implement everything by myself? For later option (extending View), I actually even don&#39;t know how to show a text caret and blink it, not mentionging moving the caret with user typing.

I am desperate now... Any hints?


Thanks!

-Tony

-----
(_EDIT_)
------
After some further investigation, it looks like extending EditText would be my best bet. I somehow figured out how to use those Span classes and guess I should be able to do most of the tricks by using (extending) them.

For example, extending the BulletSpan and overriding drawLeadingMargin should give me the control of the bullet appereances. Extending the LeadingMarginSpan should help me on the numbered list.

As to the table, my initial plan is to extend the LineBackgroundSpan and draw all the table borders in the drawBackground override. However, I still need to figure out how to layout all the text in the table cells and properly handle the caret movement and selection. Suggestions?


Implementing a rich text editor in Android?

I&#39;ll admit straight off that I&#39;m new to development and trying my hand at Android. I&#39;ve been trying to search the &#39;net to find advice on how to implement some &quot;Hold Button to Repeat Action&quot; - I&#39;ve created a custom numpad from buttons and want a backspace-like behaviour. Having got so far, I called upon a friend who hasn&#39;t coded Android before, but done lots of C# / Java and seems to know what he&#39;s doing.

The code below works just fine, but I feel it could be done more neatly.  I apologise if I&#39;ve missed bits out, but hopefully this explains my approach.  I think the onTouchListener is ok, but the way Threads are handled doesn&#39;t feel right.

Is there a better or more simple way to do this?

    public class MyApp extends Activity {
	
	private boolean deleteThreadRunning = false;
	private boolean cancelDeleteThread = false;
	private Handler handler = new Handler();
		
	public void onCreate(Bundle icicle) {
		super.onCreate(icicle);
		
		//May have missed some declarations here...
			
		Button_Del.setOnTouchListener(new OnTouchListener() {
			public boolean onTouch(View v, MotionEvent event) {
				
		       switch (event.getAction())
		       {
			       case MotionEvent.ACTION_DOWN:
			       {
			    	   handleDeleteDown();
			    	   return true;
			       }
			       
			       case MotionEvent.ACTION_UP:
			       {
			    	   handleDeleteUp();
			    	   return true;
			       }
			       
			       default:
			    	   return false;
		       }
		    }
	
			private void handleDeleteDown() {
	
				if (!deleteThreadRunning)
					startDeleteThread();
			}
	
			private void startDeleteThread() {

				Thread r = new Thread() {
					
					@Override
					public void run() {
						try {
							
							deleteThreadRunning = true;
							while (!cancelDeleteThread) {
								
								handler.post(new Runnable() {	
									@Override
									public void run() {
										deleteOneChar();
									}
								});
								
								try {
									Thread.sleep(100);
								} catch (InterruptedException e) {
									throw new RuntimeException(
										&quot;Could not wait between char delete.&quot;, e);
								}
							}
						}
						finally
						{
							deleteThreadRunning = false;
							cancelDeleteThread = false;
						}
					}
				};
				
				// actually start the delete char thread
				r.start();
			}
		});
	}
	
	private void handleDeleteUp() {
		cancelDeleteThread = true;
	}
	
	private void deleteOneChar()
	{
		String result = getNumberInput().getText().toString();
		int Length = result.length();
		
		if (Length &gt; 0)
			getNumberInput().setText(result.substring(0, Length-1));
			//I&#39;ve not pasted getNumberInput(), but it gets the string I wish to delete chars from
	}
