もともと、私は自分のものを持っていて、Adapter extended the BaseAdapterうまくいきます。そこで、以下のコードでコモンズウェアの EndlessAdapter を採用してみました。
public class MyEndlessAdapter extends EndlessAdapter {
private RotateAnimation rotate = null;
private View pendingView = null;
private List<Map<String, Object>> mData = null;
private String link, type;
String[] videoInfo= new String[90];
private Bitmap[] thumbnail = new Bitmap[10];
Context context;
public MyEndlessAdapter(Context ctxt, List<Map<String, Object>> data) {
super(new MyEndlessAdapter(ctxt, data));
new MyAdapter(ctxt, data);
context = ctxt;
rotate = new RotateAnimation(0f, 360f, Animation.RELATIVE_TO_SELF,
0.5f, Animation.RELATIVE_TO_SELF, 0.5f);
rotate.setDuration(600);
rotate.setRepeatMode(Animation.RESTART);
rotate.setRepeatCount(Animation.INFINITE);
}
public List<Map<String, Object>> get() {
MyAdapter a2 = (MyAdapter) getWrappedAdapter();
return a2.get();
}
@Override
protected View getPendingView(ViewGroup parent) {
View row = LayoutInflater.from(parent.getContext()).inflate(
R.layout.row, null);
pendingView = row.findViewById(android.R.id.text1);
pendingView.setVisibility(View.GONE);
pendingView = row.findViewById(R.id.throbber);
pendingView.setVisibility(View.VISIBLE);
startProgressAnimation();
return (row);
}
public void getInfromation(String type, String link) {
this.link = link;
this.type = type;
}
@Override

メイン アクティビティで特定のアイテムがクリックされたときに、mData からデータを取得したいと考えています。
