并且还找到了加载方法，我正在实现滚动加载更多项目
private void loadData (boolean inBackground) {
int categoryId = -1;
if (mParentCategory != null)
categoryId = mParentCategory.getId();
mIsInBackground = inBackground;
if (mIsInBackground == false)
showProgressDialog();
else
disableBackButton();
// TODO districts.
ForSaleServerManager.getInstance().getListings(this, mSearchQuery,
categoryId, -1, mSellingTypeId, mPageNumber, this);
}
以下是在适配器中设置数据
if (mPageNumber == 1) {
// add all pinning items.
if (items.getPinnedItems() != null && items.getPinnedItems().size() > 0)
allItems.addAll(items.getPinnedItems());
if (mMode == MODE_SEARCH) {
// handle post ad listing item.
if ((allItems.size() % 2) != 0)
allItems.add(new ItemResponse(ForSaleConstants.POST_AD_LISTING_ID));
}
}
// add all normal items.
if (items.getNormalItems() != null && items.getNormalItems().size() > 0)
for (int i = 0; i < items.getNormalItems().size(); i++) {
if (allItems.contains(items.getNormalItems().get(i)) == false)
allItems.add(items.getNormalItems().get(i));
}
if (allItems != null && allItems.size() > 0) {
if (mAdapter == null) {
mAdapter = new ItemsListAdapter2(ItemsActivity.this, allItems);
mListView.setAdapter(mAdapter);
mListView.setVisibility(View.VISIBLE);
mNoDataFound.setVisibility(View.GONE);
} else {
mAdapter.setData(allItems);
mAdapter.notifyDataSetChanged();
mListView.setVisibility(View.VISIBLE);
mNoDataFound.setVisibility(View.GONE);
}
} else {
mListView.setVisibility(View.GONE);
mNoDataFound.setVisibility(View.VISIBLE);
showNoData(R.drawable.icon_listing_unselected, R.string.error_categories_found);
}
