Question

I want to add a GirdView inside a ListView ? Is it possible ? where I set a different adapter for each

edit // upon the following code (gridView) deosn’t appear why?

this is thew adapter for GridView

package com.android.utils;

import java.util.ArrayList;

import android.app.Activity;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.widget.BaseAdapter;
import android.widget.TextView;

import com.android.uis.R;


public class TimesAdapter extends BaseAdapter {

    private ArrayList<String> listTitle;
    private ArrayList<String> listDates;
    private Activity activity;

    public TimesAdapter(Activity activity, ArrayList<String> listDates,ArrayList<String> listTitle){
        this.listTitle=listTitle;
        this.listDates=listDates;
        this.activity=activity;
    }

    @Override
    public int getCount() {
        // TODO Auto-generated method stub
        return 0;
    }

    @Override
    public Object getItem(int position) {
        // TODO Auto-generated method stub
        return null;
    }

    @Override
    public long getItemId(int position) {
        // TODO Auto-generated method stub
        return 0;
    }

    @Override
    public View getView(int position, View convertView, ViewGroup parent) {
        // TODO Auto-generated method stub
        ViewHolder view;
        LayoutInflater inflator = activity.getLayoutInflater();
        if(convertView==null){
            view = new ViewHolder();
            //inflate : inflate xml resources into object
            convertView = inflator.inflate(R.layout.gridview_times_row, null);
            view.tvTitle=(TextView) convertView.findViewById(R.id.tvTitle);
            view.tvDate=(TextView) convertView.findViewById(R.id.tvDate);

            convertView.setTag(view);

        }else{
            view = (ViewHolder) convertView.getTag();
        }
        view.tvTitle.setText(listTitle.get(position));      
        view.tvDate.setText(listDates.get(position));
        return convertView;
    }

    static class ViewHolder{
        public TextView tvTitle;
        public TextView tvDate;
    }

}

This is the class of ListView(that show a GridView) with it’s adapter class

Answer 1

Your TimesAdapter does not contain any data. The getCount() method always returns 0 which is telling the OS that there are no entries.
