how to know the coordinates of image when mouse over

Question

Hi all

How to get image coordinates at mouse hover position.

Please let me know

Thank you

Answer 1

Quoted from the "android-porting" mailing list (end of August 2010):

Android currently doesn't support mouse input, so has no concept of mouse hover.

Answer 2

As stakx said, Android doesn't support the mouse. However, if you are referring to the image that currently has focus, try this:

Image focusedImg = getViewById(R.id.YourMainLayout).findFocus();

int[] relativeToParentPixels = { focusedImg.getLeft(), focusedImg.getTop(), 
                                 focusedImg.getRight(), focusedImg.getBottom() };

Now you'll have the boundary positions of the image in an array.

Answer 3

You set an onTouchListener for the image, and in the onTouch event, you can pull the x,y coordinates out of the MotionEvent. getX and getY will get you the x and y coordinates in relation to the image, and getRawX and getRawY will get the x,y coordinates of the screen.

public boolean onTouch(View arg0, MotionEvent arg1) {
   System.out.println("X: "+arg1.getX());
   System.out.println("Y: "+arg1.getY());
   System.out.println("Raw X: "+arg1.getRawX());
   System.out.println("Raw Y: "+arg1.getRawY());
   return true;
}
