public void setViewPager(ViewPager viewPager) {
if (viewPager == null) {
tabsContainer.removeAllViews();
if (this.viewPager != null) {
this.viewPager.removeOnAdapterChangeListener(adapterChangeListener);
this.viewPager.removeOnPageChangeListener(this);
}
this.viewPager = viewPager;
return;
}

this.viewPager.addOnPageChangeListener(this);
adapterChangeListener = new ViewPager.OnAdapterChangeListener() {
@Override
public void onAdapterChanged(@NonNull ViewPager viewPager, @Nullable PagerAdapter oldAdapter, @Nullable PagerAdapter newAdapter) {
listenToAdapterChanges(newAdapter);
}
};

listenToAdapterChanges(viewPager.getAdapter());
}
示例2: setupWithViewPager
import android.support.v4.view.ViewPager; //导入方法依赖的package包/类
private void setupWithViewPager(@Nullable final ViewPager viewPager, boolean autoRefresh,
boolean implicitSetup) {
if (mViewPager != null) {

// listeners and observers
