本文整理了Java中android.graphics.Rect.intersect方法的一些代码示例，展示了Rect.intersect的具体用法。这些代码示例主要来源于Github/Stackoverflow/Maven等平台，是从一些精选项目中提取出来的代码，具有较强的参考意义，能在一定程度帮忙到你。Rect.intersect方法的具体详情如下：
包路径：android.graphics.Rect
类名称：Rect
方法名：intersect

Rect.intersect介绍

[英]If the rectangle specified by left,top,right,bottom intersects this rectangle, return true and set this rectangle to that intersection, otherwise return false and do not change this rectangle. No check is performed to see if either rectangle is empty. Note: To just test for intersection, use #intersects(Rect,Rect).
[中]如果左、上、右、下指定的矩形与该矩形相交，则返回true并将该矩形设置为该相交，否则返回false且不更改该矩形。不执行任何检查以查看任一矩形是否为空。注意：要测试交叉点，请使用#intersects（Rect，Rect）。
