Android showing status bar click button

Question

In my android app, i have 3 full screen ImageButtons ( horizontally inside LinearLayout) and i have hidden the status bar (full screen app)

The problem is that when i swipe down to show the status bar, the ImageButton on top, gets clicked, i tried detecting the clicks so i disable button's functionality if it is a swipe not a click like this

@Override
public boolean onTouchEvent(MotionEvent event)
{
    switch (event.getAction())
    {
        case MotionEvent.ACTION_DOWN :
            y1 = event.getY();

            i=0;

            break;
        case MotionEvent.ACTION_UP:
            y2 = event.getY();

            float deltaY = y2-y1; 
            if(deltaY < 10 && deltaY > -10)
            {
                flag=true;
            }
            else
            {
                flag=false;
            }
            break;
    }
    return super.onTouchEvent(event);
}

But it doesn't seem to work.

Any help would be very appreciated, Thank you in advance.

        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_birthday);


    }

    public void speech(View v)

                float Delta = x2-x1;

                //if on actionUp, the distance is big == swipe 
                if(Delta < 5 && Delta(-5))
                {

                }
                else
                {

                }

        }
        return super.onTouchEvent(event);
    }

The return of onTouchEvent is true if you consumed the action and false if you haven't.

So, you should to this -

@Override
public boolean onTouchEvent(MotionEvent event)
{
    switch (event.getAction())
    {
        case MotionEvent.ACTION_DOWN :{
            //something
            return true;
        }
        case MotionEvent.ACTION_UP: {
            //something else
            return true;
        }
    }
    //some other event, let system handle it
    return super.onTouchEvent(event);
}
