Question

我正在查看MaterialDesignLibrary的演示应用。

在manifest中，它使用AppTheme

<application android:allowBackup="true" android:label="@string/app_name" android:icon="@mipmap/ic_launcher" android:theme="@style/AppTheme">

AppTheme只是Theme.Light

<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="android:Theme.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. -->
    </style>

</resources>

但是，如果我在我的应用程序中使用相同的主题，我会得到一个动作栏，但不是他们的（使用布局渲染器和模拟器）。有谁知道他们如何设法隐藏行动栏？

编辑这是我的代码

以下是渲染器在加载演示应用时显示的内容

他们的应用程序的布局渲染器中没有操作栏，但是我的设置就是{ - 1}}。这是我的：

Answer 1

似乎在API 21中

 this.supportRequestWindowFeature(Window.FEATURE_NO_TITLE);

不起作用。

尝试将此添加到AndroidManifest.xml文件

 android:theme="@android:style/Theme.NoTitleBar.Fullscreen"

或添加此

 this.getActionBar().hide();

在super.onCreate（savedInstanceState）之后的onCreate方法中

;

Action Bar如何隐藏在这里？
