用法

1、布局

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
          xmlns:tools="http://schemas.android.com/tools"
          android:layout_width="match_parent"
          android:layout_height="match_parent"
          android:orientation="vertical"
          tools:context=".MainActivity">

    <android.support.v4.view.ViewPager
        android:id="@+id/viewpager"
        android:layout_width="match_parent"
        android:layout_height="0dp"
        android:layout_weight="1"/>

    <com.halzhang.android.library.BottomTabIndicator
        android:id="@+id/indicator"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:background="@android:color/background_dark"
        android:paddingBottom="10dp"
        android:paddingTop="10dp"/>
</LinearLayout>

2、初始化

public class MainActivity extends AppCompatActivity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        ViewPager viewPager = (ViewPager) findViewById(R.id.viewpager);
        viewPager.setAdapter(new MyPagerAdapter());
        BottomTabIndicator indicator = (BottomTabIndicator) findViewById(R.id.indicator);
        indicator.setViewPager(viewPager, 0);
    }

4、自定义Adapter，需要继承 BottomTabFragmentPagerAdapter 或者 BottomTabPagerAdapter

    private class MyPagerAdapter extends BottomTabFragmentPagerAdapter {

        public MyPagerAdapter() {
            super(getSupportFragmentManager());
        }

        @Override
        public int getCount() {
            return 4;
        }

        @Override
        public Fragment getItem(int position) {
            return TextFragment.newInstance(position);
        }

        @Override
        public int getPageIcon(int position) {
            return R.drawable.ic_tab;
        }

        @Override
        public CharSequence getPageTitle(int position) {
            return "Tab " + position;
        }
    }

3、自定义tab字体大小和颜色

    <style name="bottom_tab_indicator">
        <item name="android:textSize">10sp</item>
        <item name="android:textColor">@color/tab_text_color</item>
    </style>
