Slow button response in Android GridLayout

When I put my Buttons in a GridLayout the touch response is visually different than normally. On quick touch the change from default state to pressed state looks like normal, but when I touch and hold there is a very noticeable delay before the pressed button drawable is shown. Any idea of why?

I have tried to move the Button outside of the GridLayout and then it behaves like normal again - it changes to pressed state immediately. I have also tried android:longClickable="false" but that didn't solve the problem.

Here is my simple test: 

<GridLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content">

    <Button
        android:layout_width="80dp"
        android:layout_height="80dp"
        android:text="1"
        android:textStyle="bold"
        android:textSize="40dp"
        android:background="@drawable/num_button"/> <!-- Same result without this drawable-->
</GridLayout>

My test device is a Google Nexus 10 running KitKat.

I had the same problem, but I found a fix in a similar post here on SO.

You need to override a button and add the following code:

public boolean onTouchEvent (MotionEvent event) 
{
    if (event.getAction() == MotionEvent.ACTION_DOWN) setPressed(true);
    return super.onTouchEvent(event);
}
