Here's a simple example with only an Activity and a View. If you press
the pointer and then the dpad-down key. You will see the following
output:
Pointer pressed
Pointer released
Key released: 20
where the key pressed callback is missing. If you then press the dpad-
down again, you will get
Key pressed: 20
Key released: 20
which is the desired behavior.
public class MyActivity extends Activity
{
public void onCreate(Bundle icicle)
{
super.onCreate(icicle);
setContentView(new MyView(this));
}
public class MyView extends View
{
public MyView(Context context)
{
super(context);
setFocusable(true);
setFocusableInTouchMode(true);
}
public boolean onKeyDown(int keyCode, KeyEvent event)
{
Log.i("test", "Key pressed: " + keyCode);
return true;
}
public boolean onKeyUp(int keyCode, KeyEvent event)
{
Log.i("test", "Key released: " + keyCode);
return true;
}
public boolean onTouchEvent(MotionEvent event)
{
switch (event.getAction())
{
case MotionEvent.ACTION_DOWN:
Log.i("test", "Pointer pressed");
break;
case MotionEvent.ACTION_UP:
Log.i("test", "Pointer released");
break;
}
return true;
}
}
}
