android 动态设置全屏

实现全屏函数：

private void setFullScreen(){
     getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN,WindowManager.LayoutParams.FLAG_FULLSCREEN);
 }

退出全屏函数：

private void quitFullScreen(){

final WindowManager.LayoutParams attrs = getWindow().getAttributes();

attrs.flags &= (~WindowManager.LayoutParams.FLAG_FULLSCREEN);

getWindow().setAttributes(attrs);

getWindow().clearFlags(WindowManager.LayoutParams.FLAG_LAYOUT_NO_LIMITS);

   }
