我正在尝试使用gradle和circleCI构建我的android项目,但是我遇到了这个错误:

* What went wrong:
  A problem occurred configuring root project '<myproject>'.

有人可以解释一下我为什么会遇到这个问题吗？

我正在尝试在android中使用tabbedActivity来创建一个简单的应用程序.我想把我的标签放在屏幕的底部.

这是我在使用android studio创建Activity时所拥有的.

我想要的是,"第1节第2节第3节"的部分位于屏幕的底部.

这是我的xml文件:

<android.support.design.widget.AppBarLayout
    android:id="@+id/appbar"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:paddingTop="@dimen/appbar_padding_top"
    android:theme="@style/AppTheme.AppBarOverlay">

    <android.support.v7.widget.Toolbar
        android:id="@+id/toolbar"
        android:layout_width="match_parent"
        android:layout_height="?attr/actionBarSize"
        android:background="?attr/colorPrimary"
        app:layout_scrollFlags="scroll|enterAlways"
        app:popupTheme="@style/AppTheme.PopupOverlay">

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

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

</android.support.design.widget.AppBarLayout>

<android.support.v4.view.ViewPager
    android:id="@+id/container"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    app:layout_behavior="@string/appbar_scrolling_view_behavior" />

这段代码包含在一个CoordinatorLayout.问题是,如果我TabLayout把它放在viewPager之后,它会从屏幕上删除.

有人有想法吗？
