how to know the coordinates of image when touch

How to get image coordinates at mouse开发者_Go百科 hover position.

Please let me know

Thank you

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.

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;
}

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.
