Disable a whole activity from user action

Question

Is there a simple way to disable a user interacting with an activity. To be done when there is an action running (and a spinning progress bar in the title bar)

EDIT:

Answer 1

I solved this by adding an full screen blank image with a null click handler at the end on the XML layout.

Create a transparent PNG file in the drawables folder.

Add a full screen ImageView at the end of the XML layout referencing the image:

...
 

Add the null click hander for the image to capture user touches:

public void doNothingClick(View v){
    // do nothing with the click
}

Add the code to disable the user touches:

private void StopTouches(int duration){
    findViewById(R.id.imgMask).setVisibility(View.VISIBLE);
    Handler handler = new Handler();
    handler.postDelayed(new Runnable() {
        @Override
        public void run() {
            findViewById(R.id.imgMask).setVisibility(View.GONE);
        }
    }, duration);
}
