Introduction

In this page you can find the example usage for android.graphics Rect offset.

Prototype

public void offset(int dx, int dy) 

Source Link

Document

Offset the rectangle by adding dx to its left and right coordinates, and adding dy to its top and bottom coordinates.

Usage

From source file:Main.java

static Rect getViewAbsRect(View view, int parentX, int parentY) {
    int[] loc = new int[2];
    view.getLocationInWindow(loc);/*w  w w  .j a v  a2 s  .  c  o  m*/
    Rect rect = new Rect();
    rect.set(loc[0], loc[1], loc[0] + view.getMeasuredWidth(), loc[1] + view.getMeasuredHeight());
    rect.offset(-parentX, -parentY);
    return rect;
}
