フラグメント内に listView があります。
私はネットからいくつかのjsonを取得し、それをに渡しList<List<String>>
ます.
何らかの理由でリストが機能しません..クラッシュはなく、logcat には疑わしいものは何もありません..
ListView には何も表示されません。
アダプターの呼び出し (フラグメントから):
setListAdapter(new MobileArrayAdapter(getActivity(), items));
これは私のアダプターのコードです:
パッケージcom.example.free; java.util.List をインポートします。
import android.content.Context;
import android.util.Log;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.widget.ArrayAdapter;
import android.widget.ImageView;
import android.widget.ProgressBar;
import android.widget.TextView;
import android.widget.Toast;
public class MobileArrayAdapter extends ArrayAdapter<String> {
private final Context context;
public List<List<String>> items;
//private final static String[] a={"s"};
public MobileArrayAdapter(Context context, List<List<String>> items) {
super(context, R.layout.list_item);
this.context = context;
this.items = items;
}
@Override
public View getView(int position, View convertView, ViewGroup parent) {
LayoutInflater inflater = (LayoutInflater) context
.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
View rowView = inflater.inflate(R.layout.list_item, parent, false);
TextView title = (TextView) rowView.findViewById(R.id.title);
ProgressBar loader = (ProgressBar) rowView.findViewById(R.id.loader);
ImageView image = (ImageView) rowView.findViewById(R.id.itemimgae);
TextView views = (TextView) rowView.findViewById(R.id.views);
TextView likes=(TextView) rowView.findViewById(R.id.likes);
TextView upvote=(TextView) rowView.findViewById(R.id.upvote);
TextView downvote=(TextView) rowView.findViewById(R.id.downvote);
TextView desc=(TextView) rowView.findViewById(R.id.desc);
TextView pub =(TextView) rowView.findViewById(R.id.pub);
TextView idnum =(TextView) rowView.findViewById(R.id.idnum);
Log.e("title",items.get(1).get(1));
title.setText(" "+items.get(1).get(position));
views.setText(items.get(6).get(position));
likes.setText(items.get(7).get(position));
upvote.setText(items.get(8).get(position));
downvote.setText(items.get(9).get(position));
desc.setText(items.get(4).get(position));
pub.setText(items.get(5).get(position));
idnum.setText(items.get(0).get(position));
return rowView;
}
}
items
満杯です..チェックしましたが、何らかの理由でデータがアダプターに到達しません..
ここで何が問題なのですか?
