活动布局

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

<android.support.design.widget.AppBarLayout
    android:id="@+id/issue_browse_app_bar_layout"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:background="@color/app_default_color"
    app:popupTheme="@style/ThemeOverlay.AppCompat.Light"
    app:theme="@style/ThemeOverlay.AppCompat.Dark.ActionBar">

    <android.support.v7.widget.Toolbar
        android:id="@+id/issue_browse_toolbar"
        app:layout_scrollFlags="scroll|enterAlways"
        android:layout_width="match_parent"
        android:layout_height="?attr/actionBarSize" />

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

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

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

实例化后的ViewPager有2个片段
