隐藏特定活动

Question

出于某种原因，我的MainActivity工具栏再次出现（在我从我的应用程序中删除了所有工具栏之后），灰色（应用程序的其余部分为蓝色）。我想在xml中删除它，布局主题与应用程序的其余部分完全相同。这就是为什么我不确定什么是错的，并且无法在线找到任何解决方案。

样式：

    <style id="checkBoxStyle" name="checkBoxStyle" parent="Base.Theme.AppCompat">
    <item name="colorAccent">@color/colorPrimary</item>
    <item name="android:textColorSecondary">#dc302e2e</item>
    <item name="android:editTextColor">#000000</item>
</style>

我确信解决方案很简单，我只是浪费了3个小时试图解决它。非常感谢！

编辑： 我添加了一些图片： MainActivity

How the Toolbar should be

Answer 1

try this one

<style name="AppTheme.FullScreen">
    <item name="windowNoTitle">true</item>
    <item name="windowActionBar">false</item>
    <item name="android:windowFullscreen">true</item>
    <item name="android:windowContentOverlay">@null</item>
</style>

Answer 2

感谢您的帮助，但问题出现在Manifest中。 我需要为Manifest中的活动选择正确的主题，而不是在xml文件中 （相关的清单部分）：

<activity android:name=".MainActivity"
    android:theme="@style/AppTheme.NoActionBar">
    <intent-filter>
        <action android:name="android.intent.action.MAIN" />
        <category android:name="android.intent.category.LAUNCHER" />
    </intent-filter>
</activity>
