4.The original features in the `design` package are all retained.

Note changes: TabItem in the design package needs to be replaced with TabItemExt

When the project uses the Android support 28 compatibility package, the attribute app:tabMode and the attribute app:tabGravity are incompatible. Therefore, after the v1.0.2 version and later, the attribute tabMode and the attribute tabGravity are changed to app:tab_mode and app:tab_gravity. Please upgrade the code.

How to use

Bundle `ViewPager` in `layout`

For this usage, there is no need to call setupWithViewPager in the code.

<android.support.v4.view.ViewPager
    android:id="@+id/view_pager"
    android:layout_width="0dp"
    android:layout_height="0dp"
    app:layout_constraintBottom_toBottomOf="parent"
    app:layout_constraintLeft_toLeftOf="parent"
    app:layout_constraintRight_toRightOf="parent"
    app:layout_constraintTop_toTopOf="parent">

    <com.gerenvip.ui.tablayout.TabLayoutExt
        android:id="@+id/tab_layout"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:layout_gravity="top">
        <com.gerenvip.ui.tablayout.TabItemExt
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:text="Menu1"/>
        <com.gerenvip.ui.tablayout.TabItemExt
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:text="Menu2"/>
    </com.gerenvip.ui.tablayout.TabLayoutExt>
</android.support.v4.view.ViewPager>

Used in code

Dynamically add `Tab`

mTabLayout.addTab(mTabLayout.newTab().setText("Menu1"));
mTabLayout.addTab(mTabLayout.newTab().setText("Menu2"));

If you need to bundle ViewPager

mTabLayout.setupWithViewPager(mPager);
