Android 动态设置全屏，退出全屏

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);
  }
