Android. How do I keep a button displayed as PRESSED until the action created by that button is finished?

I have a button, and I want that when I press it, it stays as pressed (with the green color on Froyo).

Any help?

mycodes_Button = (Button) findViewById(R.id.mycodes); ... if (saved_Button.isPressed()) {     saved_Button.setFocusable(true); } 

Something like this?

I had this issue with a button with a custom background, and ended up using the selected state for this. That state is available for all views.

To use this you have to define a custom button background as a state list:

<selector xmlns:android="http://schemas.android.com/apk/res/android">   <item android:state_selected="false" android:state_focused="false"       android:state_pressed="false"><bitmap ... /></item>   <item android:state_selected="true"><bitmap ... /></item>   <item android:state_focused="true"><bitmap ... /></item>   <item android:state_pressed="true"><bitmap ... /></item> </selector> 

Then to use that background, let's say it is in /res/drawable/button_bg.xml in your layout file, you use:

... <Button android:background="@drawable/button_bg" ... /> ... 

In your code you can switch to the (de-)selected state in your onClick listener:

myButton.setOnClickListener(new View.OnClickListener() {   @Override   public void onClick(View v) {     v.setSelected(true);     // normal click action here   } }); 

The activated state matches the intended meaning better, but is only available from Android 3.x and higher.
