效果图:
标题和fragment联动效果已经封装好了,非常方便
<android.support.design.widget.TabLayout android:id="@+id/tabs" android:layout_width="match_parent" android:layout_height="?attr/actionBarSize" app:tabMode="scrollable"></android.support.design.widget.TabLayout> <android.support.v4.view.ViewPager android:id="@+id/vp" android:layout_width="match_parent" android:layout_height="match_parent" android:layout_below="@id/tabs"></android.support.v4.view.ViewPager>
配置要特别注意
