BottomNavigationBar使用

引入依賴：

compile 'com.ashokvarma.android:bottom-navigation-bar:2.0.4'

xml佈局中使用:

<?xml version="1.0" encoding="utf-8"?>
<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical">

    <FrameLayout
        android:id="@+id/frame_container"
        android:layout_width="match_parent"
        android:layout_height="match_parent">

    </FrameLayout>


    <com.ashokvarma.bottomnavigation.BottomNavigationBar
        android:id="@+id/bottom_navigation_bar"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:layout_gravity="bottom">

    </com.ashokvarma.bottomnavigation.BottomNavigationBar>
</FrameLayout>
