A powerful, customizable and extensible ViewPager indicator framework.
Simple steps, you can integrate MagicIndicator:
- checkout out MagicIndicator, which contains source code and demo
- import module magicindicator and add dependency:
compile project(':magicindicator')
- 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:
final 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 getItemView(Context context, final int index) {
ClipPagerTitleView clipPagerTitleView = new ClipPagerTitleView(context);
clipPagerTitleView.setText(mTitleDataList.get(index));
clipPagerTitleView.setTextColor(Color.parseColor("#f2c4c4"));
clipPagerTitleView.setClipColor(Color.WHITE);
clipPagerTitleView.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
mPager.setCurrentItem(index);
}
});
return clipPagerTitleView;
}
@Override
public IPagerIndicator getIndicator(Context context) {
return null;
}
});
magicIndicator.setNavigator(commonNavigator);
- bind magicindicator to ViewPager:
mPager.addOnPageChangeListener(new ViewPager.OnPageChangeListener() {
@Override
public void onPageScrolled(int position, float positionOffset, int positionOffsetPixels) {
magicIndicator.onPageScrolled(position, positionOffset, positionOffsetPixels);
}
@Override
public void onPageSelected(int position) {
magicIndicator.onPageSelected(position);
}
@Override
public void onPageScrollStateChanged(int state) {
magicIndicator.onPageScrollStateChanged(state);
}
});
Now, enjoy yourself!
