Android 设置activity不显示标题栏和状态栏

protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); //隐藏标题栏以及状态栏 getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN, WindowManager.LayoutParams.FLAG_FULLSCREEN); /**标题是属于View的，所以窗口所有的修饰部分被隐藏后标题依然有效,需要去掉标题**/ requestWindowFeature(Window.FEATURE_NO_TITLE); setContentView(R.layout.activity_qi_dong);
