TabLayout(核心代码)

XML:

<android.support.design.widget.TabLayout    android:id="@+id/tab_titles"    android:layout_width="match_parent"    android:layout_height="0dp"    android:layout_weight="1" /><android.support.v4.view.ViewPager    android:id="@+id/viewpagers"    android:layout_width="match_parent"    android:layout_height="0dp"    android:layout_weight="9" />

逻辑代码：
