Android 隐藏系统状态栏和标题栏

Android中若想 隐藏系统状态栏和标题栏（全屏显示）的简单方法如下：

  @Override
public void onCreate(Bundle savedInstanceState) {
 super.onCreate(savedInstanceState);
 hideStatusBar();
 setContentView(R.layout.main);
  }
  //在 Activity.setCurrentView()之前调用
  public void hideStatusBar(){
    //隐藏标题
    requestWindowFeature(Window.FEATURE_NO_TITLE);
   //定义全屏参数
    int flag =WindowManager.LayoutParams.FLAG_FULLSCREEN;
   //获得窗口对象
    Window curWindow = this.getWindow();
   //设置Flag标示
    curWindow.setFlags(flag, flag);
  }
