Question

我已经尝试过应该让它起作用的解决方案（自定义样式）：

文件夹 res \ values-v21 \ styles.xml ：

<?xml version="1.0" encoding="utf-8"?>
<resources>

    <!-- Base application theme. -->
    <style name="AppTheme" parent="AppTheme.Base"/>
    <!-- inherit from material theme -->
    <style name="AppTheme.Base" parent="android:Theme.Material">
        <!-- colorPrimary is used for the default action bar background -->
        <item name="android:colorPrimary">#3F51B5</item>

        <!-- colorPrimaryDark is used for the status bar -->
        <item name="android:colorPrimaryDark">#303F9F</item>

        <!-- colorAccent is used for the default value for colorControlActivated
                which is used to tint widgets -->
        <item name="android:colorAccent">#FF4081</item>
    </style>

    <style name="MyCustomTabLayout" parent="Widget.Design.TabLayout">
        <item name="tabIndicatorColor">#DD4081</item>
    </style>

</resources>

myFragment.xml中的标签布局：

<android.support.design.widget.TabLayout
     android:id="@+id/tabs"
     style="@style/MyCustomTabLayout"
     android:layout_width="match_parent"
     android:layout_height="wrap_content"/>

*使用compile 'com.android.support:design:+'

backtrace （由于我已经迁移到Android Studio，我无法在Eclipse中看到堆栈跟踪.Logcat会打印一些东西但不会显示崩溃的实际情况）：

Answer 1

AppCompat元素（如TabLayout）通过检查当前主题是否已定义＆＃34; colorPrimary＆＃34;来检查它们是否在具有Theme.AppCompat主题的Activity中。属性。你使用了＆＃34; colorPrimary＆＃34;来自＆＃34; android＆＃34;的属性命名空间，它不是AppCompat使用的命名空间。加 <item name="colorPrimary">#3F51B5</item>（没有安卓名称空间）到您活动的主题。

即使在为TabLayout创建样式后出现错误，也会出现类android.support.design.widget.TabLayout
