Android TabLayout(选项卡布局)简单用法实例分析

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
  android:layout_width="match_parent"
  android:layout_height="match_parent"
  xmlns:app="http://schemas.android.com/apk/res-auto"
  android:orientation="vertical">
  <android.support.design.widget.TabLayout
    android:id="@+id/tab_FindFragment_title"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:background="@color/titleBlue"
    app:tabIndicatorColor="@color/white"
    app:tabSelectedTextColor="@color/gray"
    app:tabTextColor="@color/white"
    />
  <android.support.v4.view.ViewPager
    android:id="@+id/vp_FindFragment_pager"
    android:layout_width="fill_parent"
    android:layout_height="0dp"
    android:layout_weight="1"
    />
</LinearLayout>

app:tabIndicatorColor="@color/white" // 下方滚动的下划线颜色
app:tabSelectedTextColor="@color/gray" // tab被选中后，文字的颜色
app:tabTextColor="@color/white" // tab默认的文字颜色
