A powerful, customizable and extensible ViewPager indicator framework. As the best alternative of ViewPagerIndicator, TabLayout and PagerSlidingTabStrip.
Usage
Simple steps, you can integrate MagicIndicator:
checkout out MagicIndicator, which contains source code and demo
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'}
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>
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);
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:
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) { } }
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) { } }
use CommonPagerTitleView to load custom layout xml.
Now, enjoy yourself!
