# SingleHandMode（单手模式）
基于Android M，修改系统源码实现单手模式。
--------------------------------------------------------------------------------------------------------------------------------------

ANDROID从版本4.2开始提供了一个显示管理服务DisplayManagerService,支持多种显示类型的多个显示器的镜像显示，包括内建的显示类型（本地）、HDMI显示类型以及支持WIFI Display 协议( MIRACAST)，实现本地设备在远程显示器上的镜像显示。
--------------------------------------------------------------------------------------------------------------------------------------

修改DMS,在其中添加一个触发单手模式的方法 void singleHandModeChange(boolean change,boolean left).

真正单手模式的改变屏幕的大小是在LogicalDisplay.java中，通过修改mTempDisplayRect实现显示屏幕的的改变。

#SingleHandMode（单手模式）的触发方式
通过快滑动依次点击Home按键和Back按键启动单手模式（屏幕缩小到左下角，屏幕宽高变为原始屏幕的3/4）。此时再重复上述手势，则退出单手模式。
