Get Position from OnTouchEvent

Question

I used on touch event to find the touched position by the user.I used the following code

@Override
    public boolean onTouch(View v, MotionEvent event) {

        switch (event.getAction()) {
            case MotionEvent.ACTION_DOWN:
              float x=event.getX();
              float y=event.getY();

              Log.d("MULTIPLE", "X=" + x + " Y=" + y);
         }
        return true;
     }

And according to the position some methods are called.

When i tested in different devices the x and y values changed.Is there any way to get a unique value for x and y across all devices

Answer 1

I solved this in the following way

The mid point of the device can be find out this way

X=devicewidth * 0.5

Y=deviceHeight * 0.5

Call 0.5 as heightFactor and widhtFactor

Any other points in the device have its own heightFactor and widhtFactor

We get X and Y value from onTouch event (event.getX() and event.getY())

So to find heightFactor and widhtFactor

heightFactor =X/deviceHeight

widhtFactor=Y/devicewidth

thus we get heightFactor and widhtFactor for each point which will be same for all device
