Usage

Simple steps, you can integrate MagicIndicator:

  1. checkout out MagicIndicator, which contains source code and demo
  2. import module magicindicator and add dependency:
  implementation project(':magicindicator')

or

  repositories {
      ...
      maven {
          url "https://jitpack.io"
      }
  }

dependencies { ... implementation 'com.github.hackware1993:MagicIndicator:1.6.0' // for support lib implementation 'com.github.hackware1993:MagicIndicator:1.7.0' // for androidx }

  1. add MagicIndicator to your layout xml:
  
  

  <net.lucode.hackware.magicindicator.magicindicator android:id="@+id/magic_indicator" android:layout_width="match_parent" android:layout_height="40dp"></net.lucode.hackware.magicindicator.magicindicator>

  <android.support.v4.view.viewpager android:id="@+id/view_pager" android:layout_width="match_parent" android:layout_height="0dp" android:layout_weight="1"></android.support.v4.view.viewpager>
  1. find MagicIndicator through code, initialize it:
  MagicIndicator magicIndicator = (MagicIndicator) findViewById(R.id.magic_indicator);
  CommonNavigator commonNavigator = new CommonNavigator(this);
  commonNavigator.setAdapter(new CommonNavigatorAdapter() {

  @Override
  public int getCount() {
      return mTitleDataList == null ? 0 : mTitleDataList.size();
  }

  @Override
  public IPagerTitleView getTitleView(Context context, final int index) {
      ColorTransitionPagerTitleView colorTransitionPagerTitleView = new ColorTransitionPagerTitleView(context);
      colorTransitionPagerTitleView.setNormalColor(Color.GRAY);
      colorTransitionPagerTitleView.setSelectedColor(Color.BLACK);
      colorTransitionPagerTitleView.setText(mTitleDataList.get(index));
      colorTransitionPagerTitleView.setOnClickListener(new View.OnClickListener() {
          @Override
          public void onClick(View view) {
              mViewPager.setCurrentItem(index);
          }
      });
      return colorTransitionPagerTitleView;
  }

  @Override
  public IPagerIndicator getIndicator(Context context) {
      LinePagerIndicator indicator = new LinePagerIndicator(context);
      indicator.setMode(LinePagerIndicator.MODE_WRAP_CONTENT);
      return indicator;
  }

}); magicIndicator.setNavigator(commonNavigator);

  1. work with ViewPager:
  ViewPagerHelper.bind(magicIndicator, mViewPager);

or

work with Fragment Container(switch Fragment by hide()、show()): ```java mFramentContainerHelper = new FragmentContainerHelper(magicIndicator);

// ...

mFragmentContainerHelper.handlePageSelected(pageIndex); // invoke when switch Fragment ```

Extend

MagicIndicator can be easily extended:

  1. implement IPagerTitleView to customize tab:
  public class MyPagerTitleView extends View implements IPagerTitleView {

  public MyPagerTitleView(Context context) {
      super(context);
  }

  @Override
  public void onLeave(int index, int totalCount, float leavePercent, boolean leftToRight) {
  }

  @Override
  public void onEnter(int index, int totalCount, float enterPercent, boolean leftToRight) {
  }

  @Override
  public void onSelected(int index, int totalCount) {
  }

  @Override
  public void onDeselected(int index, int totalCount) {
  }

}

  1. implement IPagerIndicator to customize indicator:
  public class MyPagerIndicator extends View implements IPagerIndicator {

  public MyPagerIndicator(Context context) {
      super(context);
  }

  @Override
  public void onPageSelected(int position) {
  }

  @Override
  public void onPageScrolled(int position, float positionOffset, int positionOffsetPixels) {
  }

  @Override
  public void onPageScrollStateChanged(int state) {
  }

  @Override
  public void onPositionDataProvide(List<positiondata> dataList) {
  }

}

  1. use CommonPagerTitleView to load custom layout xml.

Now, enjoy yourself!
