Question

我从android（和java）开发开始，正在构建一个关于碎片化应用程序的google文档的示例，并根据android studio的发现功能更改activity_collection_demo.xml使用＆＃34;＃33b5e5＆＃34;的唯一地方（这是显示你所在标签的颜色）当将颜色更改为另一种十六进制颜色时，没有任何变化。我已经尝试重新启动鸸..另外注释android.support.v4.view.PagerTitleStrip也不会影响代码。

这是activity_collection_demo.xml的内容

<android.support.v4.view.ViewPager xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/pager"
android:layout_width="match_parent"
android:layout_height="match_parent">

<!--
This title strip will display the currently visible page title, as well as the page
titles for adjacent pages.

<android.support.v4.view.PagerTitleStrip android:id="@+id/pager_title_strip"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:layout_gravity="top"
    android:background="#33b5e5"
    android:textColor="#fff"
    android:paddingTop="4dp"
    android:paddingBottom="4dp"/>

</android.support.v4.view.ViewPager>

如果有人能帮助我，我将非常感激！

更改代码不会更改该android应用程序（java）
