MagicIndicator
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 FragmentExtend
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!
