私は火口-esqeアプリケーションを構築するためにSwipecardsライブラリ（https://github.com/Diolor/Swipecards）を使用しようとしています。私はBaseAdapterを使用して、2つのテキストビューとメインのSwipeFlingAdapterViewに提供される画像ビューでレイアウトを設定しています。両方のテキストフィールドにデータが入力されているが、画像をカードに表示することはできません。私はArrayAdapterとBaseAdapterの両方でこの実装を試みましたが、結果は同じです。移入ImageViewの（Swipecards）
活性レイアウト（deal_page_layout）
<FrameLayout

BaseAdapterクラスによって
public class DealBaseAdapter extends BaseAdapter {
private Context context;
private List<GrubbyDeal> dealList;
private LayoutInflater li;
public DealBaseAdapter(Context context, LayoutInflater li, ArrayList<GrubbyDeal> dealList){
this.context = context;
this.dealList = dealList;
this.li = li;
}
@Override
public int getCount(){
return dealList.size();
}
@Override
public Object getItem(int position){
return dealList.get(position);
}
@Override
public long getItemId(int position){
return position;
}
@Override
public View getView(int position, View convertView, ViewGroup parent){
ViewHolder viewHolder;
//resuse a view if possible
if(convertView == null){
convertView = li.inflate(R.layout.deal_card,parent,false);
viewHolder = new ViewHolder();
viewHolder.img = (ImageView) convertView.findViewById(R.id.deal_card_image);
viewHolder.title = (TextView) convertView.findViewById(R.id.deal_card_title);
viewHolder.desc = (TextView) convertView.findViewById(R.id.deal_card_description);
convertView.setTag(viewHolder);
}
else {
viewHolder = (ViewHolder) convertView.getTag();
}
GrubbyDeal curDeal = dealList.get(position);
viewHolder.img.setImageURI(curDeal.getImageUri());
viewHolder.title.setText(curDeal.getTitle());
viewHolder.desc.setText(curDeal.getDescription());
return convertView;
}
//view holder class to hold cached findViewByID results
private static class ViewHolder {
public ImageView img;
public TextView title;
public TextView desc;
}
メイン活性（DealPage）を移入されたレイアウト
public class DealPage extends Activity {
private ArrayList<GrubbyDeal> dealList;
private DealBaseAdapter dealAdapter;
SwipeFlingAdapterView flingContainer;
@Override
public void onCreate(Bundle sis){
super.onCreate(sis);
setContentView(R.layout.deal_page_layout);
//add some awesome cat deals to the adapter
dealList = new ArrayList<>();
for(int i=0; i < 5; i++){
GrubbyDeal tmp = new GrubbyDeal(i);
dealList.add(tmp);
}
//add another type of cat deal to the list
dealList.add(new GrubbyDeal());
dealAdapter = new DealBaseAdapter(this, getLayoutInflater(), dealList);
flingContainer = (SwipeFlingAdapterView) findViewById(R.id.swipe_fling_view);
flingContainer.setAdapter(dealAdapter);
flingContainer.setFlingListener(new SwipeFlingAdapterView.onFlingListener() {
@Override
public void removeFirstObjectInAdapter() {
// this is the simplest way to delete an object from the Adapter (/AdapterView)
Log.d("LIST", "removed object!");
GrubbyDeal popped = dealList.remove(0);
dealList.add(popped);
dealAdapter.notifyDataSetChanged();
}
@Override
public void onLeftCardExit(Object dataObject) {
makeToast(DealPage.this, "Left!");
}
@Override
public void onRightCardExit(Object dataObject) {
makeToast(DealPage.this, "Right!");
}
@Override
public void onAdapterAboutToEmpty(int itemsInAdapter) {
dealList.add(new GrubbyDeal());
dealAdapter.notifyDataSetChanged();
Log.d("LIST", "notified");
}
@Override
public void onScroll(float scrollProgressPercent) {
View view = flingContainer.getSelectedView();
}
});
flingContainer.setOnItemClickListener(new SwipeFlingAdapterView.OnItemClickListener() {
@Override
public void onItemClicked(int itemPosition, Object dataObject) {
makeToast(DealPage.this, "Clicked!");
}
});
}
}
明らかなものがありませんか？私が使用すべきはるかに優れたライブラリがありますか？おかげで、

私はGlideをお勧めします –
