A powerful, customizable and extensible ViewPager indicator framework. As the best alternative of ViewPagerIndicator, TabLayout and PagerSlidingTabStrip.
Simple steps, you can integrate MagicIndicator:
- checkout out MagicIndicator, which contains source code and demo
- 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 }- add MagicIndicator to your layout xml:
<?xml version="1.0" encoding="utf-8"?> <LinearLayoutxmlns: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:
MagicIndicatormagicIndicator = (MagicIndicator) findViewById(R.id.magic_indicator); CommonNavigatorcommonNavigator = newCommonNavigator(this); commonNavigator.setAdapter(newCommonNavigatorAdapter(){@OverridepublicintgetCount(){returnmTitleDataList == null ? 0 : mTitleDataList.size()} @OverridepublicIPagerTitleViewgetTitleView(Contextcontext, finalintindex){ColorTransitionPagerTitleViewcolorTransitionPagerTitleView = newColorTransitionPagerTitleView(context); colorTransitionPagerTitleView.setNormalColor(Color.GRAY); colorTransitionPagerTitleView.setSelectedColor(Color.BLACK); colorTransitionPagerTitleView.setText(mTitleDataList.get(index)); colorTransitionPagerTitleView.setOnClickListener(newView.OnClickListener(){@OverridepublicvoidonClick(Viewview){mViewPager.setCurrentItem(index)} }); returncolorTransitionPagerTitleView} @OverridepublicIPagerIndicatorgetIndicator(Contextcontext){LinePagerIndicatorindicator = newLinePagerIndicator(context); indicator.setMode(LinePagerIndicator.MODE_WRAP_CONTENT); returnindicator} }); magicIndicator.setNavigator(commonNavigator);- work with ViewPager:
ViewPagerHelper.bind(magicIndicator, mViewPager);or
work with Fragment Container(switch Fragment by hide()、show()):
mFramentContainerHelper = newFragmentContainerHelper(magicIndicator); // ...mFragmentContainerHelper.handlePageSelected(pageIndex); // invoke when switch FragmentMagicIndicator can be easily extended:
- implement IPagerTitleView to customize tab:
publicclassMyPagerTitleViewextendsViewimplementsIPagerTitleView{publicMyPagerTitleView(Contextcontext){super(context)} @OverridepublicvoidonLeave(intindex, inttotalCount, floatleavePercent, booleanleftToRight){} @OverridepublicvoidonEnter(intindex, inttotalCount, floatenterPercent, booleanleftToRight){} @OverridepublicvoidonSelected(intindex, inttotalCount){} @OverridepublicvoidonDeselected(intindex, inttotalCount){} }- implement IPagerIndicator to customize indicator:
publicclassMyPagerIndicatorextendsViewimplementsIPagerIndicator{publicMyPagerIndicator(Contextcontext){super(context)} @OverridepublicvoidonPageSelected(intposition){} @OverridepublicvoidonPageScrolled(intposition, floatpositionOffset, intpositionOffsetPixels){} @OverridepublicvoidonPageScrollStateChanged(intstate){} @OverridepublicvoidonPositionDataProvide(List<PositionData> dataList){} }- use CommonPagerTitleView to load custom layout xml.
Now, enjoy yourself!
