Usage

Simple steps, you can integrate MagicIndicator:

  1. checkout out MagicIndicator, which contains source code and demo
  2. import module magicindicator and add dependency:

    compile project(':magicindicator')

    or

    repositories {
        ...
        maven {
            url "https://jitpack.io"
        }
    }
    
    dependencies {
        ...
        compile 'com.github.hackware1993:MagicIndicator:1.5.0'
    }
  3. add MagicIndicator to your layout xml:

    <?xml version="1.0" encoding="utf-8"?>
    <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="net.lucode.hackware.magicindicatordemo.MainActivity">
    
        <net.lucode.hackware.magicindicator.MagicIndicator
            android:id="@+id/magic_indicator"
            android:layout_width="match_parent"
            android:layout_height="40dp" />
    
        <android.support.v4.view.ViewPager
            android:id="@+id/view_pager"
            android:layout_width="match_parent"
            android:layout_height="0dp"
            android:layout_weight="1" />
    
    </LinearLayout>
  4. 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);
  5. work with ViewPager:

    ViewPagerHelper.bind(magicIndicator, mViewPager);

    or

    work with Fragment Container(switch Fragment by hide()、show()):

    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) {
        }
    }
  2. 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) {
        }
    }
  3. use CommonPagerTitleView to load custom layout xml.

Now, enjoy yourself!
