Get the touch position inside the imageview in android

Question

I have a imageview in my activity and I am able to get the position where the user touch the imageview, through onTouchListener. I placed another image where the user touch

Answer 1

You can get the top left corner of your view as follows:

int[] viewCoords = new int[2];
imageView.getLocationOnScreen(viewCoords);

From this and the touch coordinates you can calculate the point inside the ImageView:

int touchX = (int) event.getX();
int touchY = (int) event.getY();

int imageX = touchX - viewCoords[0]; // viewCoords[0] is the X coordinate
int imageY = touchY - viewCoords[1]; // viewCoords[1] is the y coordinate

Answer 2

Add these lines to ImageView

android:scaleType="fitXY" 

and

android:adjustViewBounds="true"

to your image view it is because image are not having their original dimensions in IV
