android 动态设置全屏

实现全屏函数：

private voidsetFullScreen(){

     getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN,WindowManager.LayoutParams.FLAG_FULLSCREEN);

 }

退出全屏函数：

private voidquitFullScreen(){

      finalWindowManager.LayoutParams attrs = getWindow().getAttributes();

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

      getWindow().setAttributes(attrs);

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

  }
