SlidingTabLayout错误

Question

当我尝试在xml文件中添加 SlidingTabLayout 时，会出现错误

<android.support.v4.widget.DrawerLayout

xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/DrawerLayoutTop"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:elevation="7dp">

<LinearLayout
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical">

    <include
        android:id="@+id/tool_bar"
        layout="@layout/tool_bar">
    </include>

    <com.android4devs.slidingtab.SlidingTabLayout
        android:id="@+id/tabs"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:elevation="2dp"
        android:background="@color/ColorPrimary"/>

    <android.support.v4.view.ViewPager
        android:id="@+id/pager"

        android:layout_height="match_parent"
        android:layout_width="match_parent"
        android:layout_weight="1"
        ></android.support.v4.view.ViewPager>

</LinearLayout>

<android.support.v7.widget.RecyclerView
    android:id="@+id/RecyclerView"
    android:layout_width="320dp"
    android:layout_height="match_parent"
    android:layout_gravity="left"
    android:background="#ffffff"
    android:scrollbars="vertical">

</android.support.v7.widget.RecyclerView>

这是logcat

引起：java.lang.ClassNotFoundException：未在路径上找到类“com.android4devs.slidingtab.SlidingTabLayout”：DexPathList [[zip file“/data/app/com.example.myapplication-1.apk” ]，nativeLibraryDirectories = [/ data / app-lib / com.example.myapplication-1，/ vendor / lib，/ system / lib]]

我该如何纠正？

Answer 1

这可能是因为

<style>
    @body-color:#f00;
    body {
        color:@body-color;
    }
</style>

请验证SlidingTabLayout的路径。应该是你的.package.SlidiingTabLayout
