Question

主要活动和聊天活动使用相同的主题：

  <activity
            android:name=".View.MainActivity"
            android:label="@string/title_activity_main"
            android:theme="@style/AppTheme.NoActionBar">
        </activity>

    <activity
        android:name=".View.ChatActivity"
        android:label="@string/title_activity_chat"
        android:parentActivityName=".View.MainActivity"
        android:theme="@style/AppTheme.NoActionBar"
        >
        <meta-data
            android:name="android.support.PARENT_ACTIVITY"
            android:value="ocm.my.chat.View.MainActivity"/>
    </activity>

<style name="AppTheme.NoActionBar" parent="Theme.AppCompat.Light">
    <item name="windowActionBar">false</item>
    <item name="windowNoTitle">true</item>

    <item name="android:windowDrawsSystemBarBackgrounds">true</item>
    <item name="android:statusBarColor">@color/statusTranGray </item>
</style>

然而状态栏＆＃39;颜色不同：

我无法弄清楚为什么会发生这种奇怪的事情，请帮忙。

加成

将android：statusBarColor属性更改为红色。这两个活动状态栏都是＆＃39;颜色看起来一样。都是红色的。

为什么使用相同主题的两个Activity具有不同的状态栏颜色？
