Added 6 new very useful methods. 1. getScreenXDpi() which returns the Width (X) density in DPI. 2. getScreenYDpi() which returns the Height (Y) density in DPI. 3. calculateDistanceByX() which returns the distance between the given View's X (start point of View's width) and the screen width. 4. calculateDistanceByY() which returns the distance between the given View's Y (start point of View's height) and the screen height. 5. getViewX() which returns the X coordinate of the given View on the screen. 6. getViewY() which returns the Y coordinate of the given View on the screen.

Use cast to float instead of .toFloat() for int conversion.
Tell me more
In the calculateDistanceByX and calculateDistanceByY methods, you're using .toFloat() to convert the result to a float. However, this method doesn't exist for int in Java. Instead, you should use a cast to float. Change return (getScreenWidth() - point[0]).toFloat(); to return (float)(getScreenWidth() - point[0]);. Make the same change in calculateDistanceByY.

Initialize the 'point' array with a size of 2.
Tell me more
In the calculateDistanceByX and calculateDistanceByY methods, you're initializing the point array with a size of 0. This will cause an ArrayIndexOutOfBoundsException when you try to access point[0] or point[1]. Instead, initialize the array with a size of 2 like this: int[] point = new int[2];. This will allow the getLocationOnScreen method to properly populate the array with the x and y coordinates.
