新特性：TabLayout动态添加条目

• 布局

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical">

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

    <android.support.design.widget.TabLayout
        android:id="@+id/tab_layout_menu"
        android:layout_width="match_parent"
        android:layout_height="65dp"
        android:paddingTop="@dimen/padding_5"
        app:tabIndicatorColor="@color/light_yellow"
        app:tabSelectedTextColor="@color/light_yellow"
        app:tabTextColor="@color/gray_black" />


    <android.support.v4.view.ViewPager
        android:id="@+id/vp"
        android:layout_width="fill_parent"
        android:layout_height="0dp"
        android:layout_weight="1" />

fragment自己创建几个就好了……………

附加：tablayout选中指定位置

 mTl.getTabAt(tabPosition).select();
