github lib 2 ,
githublib 3 ,
github lib 4 ,
或
试试
遵守此规定
compile ‘com.android.support:design:25.3.1’
创建布局像这样
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout 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">
<!-- Content Container -->
<android.support.design.widget.BottomNavigationView
android:id="@+id/bottom_navigation"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_alignParentBottom="true"
app:itemBackground="@color/colorPrimary"
app:itemIconTint="@color/white"
app:itemTextColor="@color/white"
app:menu="@menu/bottom_navigation_main" />
</RelativeLayout>
根据需要创建菜单
<?xml version="1.0" encoding="utf-8"?>
<menu xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto">
<item
android:id="@+id/action_favorites"
android:enabled="true"
android:icon="@drawable/ic_favorite_white_24dp"
android:title="@string/text_favorites"
app:showAsAction="ifRoom" />
<item
android:id="@+id/action_schedules"
android:enabled="true"
android:icon="@drawable/ic_access_time_white_24dp"
android:title="@string/text_schedules"
app:showAsAction="ifRoom" />
<item
android:id="@+id/action_music"
android:enabled="true"
android:icon="@drawable/ic_audiotrack_white_24dp"
android:title="@string/text_music"
app:showAsAction="ifRoom" />
**Handling Enabled / Disabled states. Make selector file.**
<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item android:color="@color/white" android:state_enabled="true" />
<item android:color="@color/colorPrimaryDark" android:state_enabled="false" />
</selector>
处理点击事件
BottomNavigationView bottomNavigationView = (BottomNavigationView)
findViewById(R.id.bottom_navigation);
bottomNavigationView.setOnNavigationItemSelectedListener(
new BottomNavigationView.OnNavigationItemSelectedListener() {
@Override
public boolean onNavigationItemSelected(@NonNull MenuItem item) {
switch (item.getItemId()) {
case R.id.action_favorites:
break;
case R.id.action_schedules:
break;
case R.id.action_music:
break;
}
return false;
}
});
