如何在安卓系统中关闭StatusBar？

Question

我已经编写了一个自定义的Action Bar。问题是，为了使用这个操作栏，我在清单中使用了我的自定义主题。我还想禁用StatusBar。我该怎么做？

<resources>

<!--
    Base application theme, dependent on API level. This theme is replaced
    by AppBaseTheme from res/values-vXX/styles.xml on newer devices.

-->
<style name="AppBaseTheme" parent="Theme.AppCompat.Light">
    <!--
        Theme customizations available in newer API levels can go in
        res/values-vXX/styles.xml, while customizations related to
        backward-compatibility can go here.
    -->
</style>

<!-- Application theme. -->
<style name="AppTheme" parent="AppBaseTheme">
    <!-- All customizations that are NOT specific to a particular API-level can go here. -->

<item name="colorPrimary">@color/red</item>
<item name="colorPrimaryDark">@color/red</item>
</style>

首先，谷歌不鼓励这种行为，说：

您不应该在没有状态栏的情况下显示操作栏。

但是，如果您坚持这样做的话。试试下面这段代码：

View decorView = getWindow().getDecorView();
// Hide the status bar.
int uiOptions = View.SYSTEM_UI_FLAG_FULLSCREEN;
decorView.setSystemUiVisibility(uiOptions);
