全屏Android窗口,无操作栏

我通过编写以下代码使应用全屏显示,没有标题

<item name="android:windowNoTitle">true</item>
<item name="android:windowFullscreen">true</item>

但是我可以像通常从顶部那样打开操作栏和通知栏。 有没有办法永远不会显示顶部动作栏。

全屏应用程序:

可见状态栏:

当我触摸并从顶部移动状态栏向下滑动时,就可以看到它。如何停止呢?

更新

尝试一下!

   @Override
        protected void onCreate(Bundle savedInstanceState) {
            super.onCreate(savedInstanceState);

            this.requestWindowFeature(Window.FEATURE_NO_TITLE);
            this.getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN, WindowManager.LayoutParams.FLAG_FULLSCREEN);
            setContentView(R.layout.activity_main);
    }

in style.xml:

<style name="AppTheme" parent="Theme.AppCompat.DayNight.NoActionBar">
</style>

清单应用程序标签中的

android:theme="@style/AppTheme"
