Android: How to prevent any touch events from being passed from a view to the one underneath it?

Add an onTouchEvent method to the view with top position then return true. True will tell the event bubbling that the event was consumed therefore prevent event from bubbling to other views.

protected boolean onTouchEvent (MotionEvent me) {
    return true;
}

For v1 you would do an import:

import android.view.View.OnTouchListener;

Then set the onTouchListener:

v1.setOnTouchListener(new OnTouchListener() {
    @Override
    public boolean onTouch(View v, MotionEvent event) {
        return true;
    }
});

From code

View v1 = new View(this);   
v1.setClickable(true);
v1.setFocusable(true);

OR

From xml

<View
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:text="My button"
    android:focusable="true"
    android:clickable="true"/>

This will prevent touch and click events from being propagated to views that stay below your view.
Or if you inflate the View then to .xml add android:clickable="true"
