bottomNavigationBar 底部导航tab MD

1.先上图：

此底部Tab完全可以满足日常的开发

2.使用：

很简单，使用Gradle构建：compile ‘com.ashokvarma.android:bottom-navigation-bar:0.9.5'

3.在布局文件中使用

<com.ashokvarma.bottomnavigation.BottomNavigationBar

android:layout_gravity="bottom"

android:id="@+id/Tab"

android:layout_width="match_parent"

android:layout_height="wrap_content"/>

4.在Activity中实例化控件，为控件设置属性

 

BottomNavigationBar bottomNavigationBar = (BottomNavigationBar) findViewById(R.id.bottom_navigation_bar);

bottomNavigationBar .addItem(new BottomNavigationItem(R.drawable.ic_home_white_24dp,"Home"))

.addItem(new BottomNavigationItem(R.drawable.ic_book_white_24dp,"Books"))

.addItem(new BottomNavigationItem(R.drawable.ic_music_note_white_24dp,"Music"))

.addItem(new BottomNavigationItem(R.drawable.ic_tv_white_24dp,"Movies & TV"))

.addItem(new BottomNavigationItem(R.drawable.ic_videogame_asset_white_24dp,"Games"))

.initialise();

5.设置监听事件，监听事件有三种状态：

• 当Item被选中状态
• 当Item不被选中状态
• 当Item再次被选中状态

bottomNavigationBar.setTabSelectedListener(new BottomNavigationBar.OnTabSelectedListener(){

@Override public void onTabSelected(int position) { }

@Override public void onTabUnselected(int position) { }

@Override public void onTabReselected(int position) { }

});
