Android 调用onListItemClick时OutOfIndex崩溃

这是我的列表适配器：

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<List<item>> {
    private final Context context;
    private final List<item> markers;
    private final static String[] a={"s"};

    public MobileArrayAdapter(Context context, List<item> markers) {
        super(context, R.layout.list_item);
        this.context = context;
        this.markers = markers;
    }

    @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);

        title.setText("      "+markers.get(position).getTitle());
        views.setText(markers.get(position).getView()+"");
        likes.setText(markers.get(position).getLike()+"");
        upvote.setText(markers.get(position).getUpvote()+"");
        downvote.setText(markers.get(position).getDownvote()+"");
        desc.setText(markers.get(position).getDesc());
        pub.setText(markers.get(position).getPub()+"");
        idnum.setText(markers.get(position).getId()+"");

        return rowView;
    }

    @Override
    public int getCount() {
        // TODO Auto-generated method stub
        return (this.markers != null) ? this.markers.size() : 0;

    }


}

第94行：

String selectedValue = (String) getListAdapter().getItem(position);

整个方法：

@Override
public void onListItemClick(ListView l, View v, int position, long id) {

    // get selected items
    String selectedValue = (String) getListAdapter().getItem(position);
    Toast.makeText(getActivity(), selectedValue, Toast.LENGTH_SHORT).show();

}

这里有什么问题？ ty

您可以执行以下操作：

@Override
public void onListItemClick(ListView l, View v, int position, long id) {

    TextView title = (TextView) v.findViewById(R.id.title);
    ProgressBar loader = (ProgressBar) v.findViewById(R.id.loader);
    ImageView image = (ImageView) v.findViewById(R.id.itemimgae);
    TextView views = (TextView) v.findViewById(R.id.views);
    TextView likes=(TextView) v.findViewById(R.id.likes);
    TextView upvote=(TextView) v.findViewById(R.id.upvote);
    TextView downvote=(TextView) v.findViewById(R.id.downvote);
    TextView desc=(TextView) v.findViewById(R.id.desc);
    TextView pub =(TextView) v.findViewById(R.id.pub);
    TextView idnum =(TextView) v.findViewById(R.id.idnum);

//than use the values
    String stLikes = likes.getText().toString();
/.....
}

干脆换成

//String selectedValue = (String) getListAdapter().getItem(position);
String selectedValue = markers.get(position).getTitle();

或者尝试重写

getItem（）

，并将项目返回到那里

编辑

我不确定您的数据，但您可以在getItem（）中返回数据对象，如下所示

@Override
    public Object getItem(int position) {
        return "123";
    }

---

这只是一个样品。。如果您现在调用

getListAdapter（）.getItem（position）

，它将返回123个字符串，您可以根据您的数据要求对其进行修改。

我正在尝试从单击的项中获取值。。不将其放入文本视图文本视图包含单击项的de值添加了解释

@Override
    public Object getItem(int position) {
        return "123";
    }
