UIView具有以下内容：
- convertPoint:toView: - convertPoint:fromView: - convertRect:toView: - convertRect:fromView:
什么是Android相当的？更一般地说,给定两个视图,我如何得到第二个View的rect在第一个坐标系？
解决方法
我不认为这是sdk的一部分,但是您似乎可以使用getLocationOnScreen轻松编写自己的实现：
public static Point convertPoint(Point fromPoint,View fromView,View toView){
int[] fromCoord = new int[2];
int[] toCoord = new int[2];
fromView.getLocationOnScreen(fromCoord);
toView.getLocationOnScreen(toCoord);
Point toPoint = new Point(fromCoord[0] - toCoord[0] + fromPoint.x,fromCoord[1] - toCoord[1] + fromPoint.y);
return toPoint;
}
public static Rect convertRect(Rect fromRect,View toView){
int[] fromCoord = new int[2];
int[] toCoord = new int[2];
fromView.getLocationOnScreen(fromCoord);
toView.getLocationOnScreen(toCoord);
int xShift = fromCoord[0] - toCoord[0];
int yShift = fromCoord[1] - toCoord[1];
Rect toRect = new Rect(fromRect.left + xShift,fromRect.top + yShift,fromRect.right + xShift,fromRect.bottom + yShift);
return toRect;
}
