How to capture when user presses "Search Soft key" in android

How to capture when user presses "Search Soft key" in android.

Can we开发者_开发技巧 do it in onKeyDown() and checking the keycode?

Try this in your Activity code:

@Override
public boolean onKeyDown( int keyCode, KeyEvent event )
{
    if ( event.getKeyCode() == KeyEvent.KEYCODE_SEARCH )
    {
        // Catch the search 
        // do something
        // return true to consume press or false to pass it on
    }
    return super.onKeyDown( keyCode, event ); 
}

I think that you are right. You can check for the key code that is given in the following list.

And prefer to check this onKeyUp.

I've done something like this for capturing the search softkey when progress dialog is showing and it worked fine for me:

progressDialog.setOnKeyListener(new DialogInterface.OnKeyListener() {
    @Override
    public boolean onKey(DialogInterface dialog, int keyCode,
            KeyEvent event) {
        if (keyCode == KeyEvent.KEYCODE_SEARCH) {
            return true;
        }
        return false;
    }
});
