1.導依賴

compile 'com.hjm:BottomTabBar:1.1.1'

2.在XML中定義一下該控制元件

<com.hjm.bottomtabbar.BottomTabBar
    android:id="@+id/bottom_tab_bar"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    >
</com.hjm.bottomtabbar.BottomTabBar>

3.定義每個Fragment,這裡列舉一個

public class OneFragment extends Fragment{
    @Nullable
    @Override
    public View onCreateView(LayoutInflater inflater, @Nullable ViewGroup container, @Nullable Bundle savedInstanceState) {
        View view = inflater.inflate(R.layout.fragment1, container, false);
        return view;

    }
}

4.MainActivity中

public class MainActivity extends AppCompatActivity {
private BottomTabBar mb;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
      mb=(BottomTabBar)findViewById(R.id.bottom_tab_bar);

        mb.init(getSupportFragmentManager())
                .setImgSize(50,50)
                .setFontSize(8)
                .setTabPadding(4,6,10)
                .setChangeColor(Color.RED,Color.DKGRAY)
                .addTabItem("月光茶人",R.drawable.tab_home, OneFragment.class)
                .addTabItem("優惠",R.drawable.tab_topic, TwoFragment.class)
                .addTabItem("購物車",R.drawable.main_index_cart_normal, ThreeFragment.class)
                .addTabItem("我的",R.drawable.main_index_my_normal, FourFragment.class)
                .isShowDivider(false)
                .setOnTabChangeListener(new BottomTabBar.OnTabChangeListener() {
                    @Override
                    public void onTabChange(int position, String name) {

                    }
                });

    }
}
