Question

I have 3 Activities A,B & C.

I present some video links in Activity A in a list. If user clicks on an item, i load Activity B in which i do some verification of user’s data such as ask him to provide his Login info in an AlertDialog. I present two buttons in this dialog to Login & Cancel. If user presses Login i verify his info and open Activity C where i play his selected video. But If user presses Cancel, i finish() Activity B to load Activity A.

This works fine if user only interacts through burrons.

But Issue arises that when i press ESCAPE button on my keyboard/D-Pad when the AlertDialog is open. The dialog disappears but the Activity B does not finish(). I have overridden onKeyDown of Activity B where i do the following.

@Override
public boolean onKeyDown(int keyCode, KeyEvent event) {
    if (keyCode == KeyEvent.KEYCODE_BACK
            || keyCode == KeyEvent.KEYCODE_ESCAPE) {
        Log.d(TAG, "onKeyDown : calling finish() manually");
        finish();
        return true;
    } else
        return false;
}

But it does not work WHEN i press ESCAPE on an open AlertDialog.

How can i achieve this?

Capture the setOnKeyListener event of AlertDialog and do paste the following code in it. It will also close the activity on BACK button:

 @Override

    public boolean onKey(DialogInterface dialog, int keyCode, KeyEvent event) 
    {
        if (keyCode == KeyEvent.KEYCODE_BACK || keyCode == KeyEvent.KEYCODE_ESCAPE)                                 
        {           
            yourActivity.finish();
            return true;
        } 
        return false;
    }
