我有這個類的FragmentPagerAdapter。做一個循環ViewPager
我怎麼能把它變成循環ViewPager？所以從A - B - C - A（後面）。我在這個論壇上嘗試了一些解決方案，但它並沒有給我帶來任何結果。
public class RootCategoriesPagerAdapter extends FragmentPagerAdapter {
private static final Logger LOG = LoggerFactory.getLogger(RootCategoriesPagerAdapter.class.getSimpleName());
private final AppDomainResult appDomain;
public RootCategoriesPagerAdapter(final AppDomainResult appDomain, final FragmentManager fragmentManager) {
super(fragmentManager);
this.appDomain = checkNotNull(appDomain, "appDomain");
}
@Override
public int getCount() {
return appDomain.getRootCategories().size();
}
@Override
public Fragment getItem(final int position) {
LOG.debug("Creating new Fragment for position {}", position);
final RootCategoryResult rootCategory = appDomain.getRootCategories().get(position);
LOG.debug("{}", rootCategory);
return createRootCategoryFragment(rootCategory);
}
private CategoryFragment createRootCategoryFragment(final RootCategoryResult rootCategory) {
return CategoryFragment.newInstance(rootCategory.getUrlKey(), createViewConfig(rootCategory));
}
private static CategoriesAdapterViewConfig createViewConfig(final RootCategoryResult rootCategory) {
//J-
return new CategoriesAdapterViewConfig()
.sourceActivity(SHOP)
.showTeasers(true)
.resourceTop(R.drawable.shop_top)
.resourceMiddle(R.drawable.shop_middle)
.resourceBottom(R.drawable.shop_bottom)
.showSearchBar(Optional.fromNullable(rootCategory.getIsHome()).or(false));
//J+
}
@Override
public CharSequence getPageTitle(final int position) {
return appDomain.getRootCategories().get(position).getLabel();
}
