Estou obtendo dados do banco de dados e exibidos em umGridView bem. Mas preciso colocar um botão separado abaixo de cada texto exibido. Quando clico no botão, tenho que fazer algumas coisas. Aqui eu usei um adaptador de lista personalizado para dados recuperados do DB. Como eu poderia fazer isso?

Meu código:

public class HomePage extends Activity  {
    private ArrayList<SingleElementDetails> allElementDetails=new ArrayList<SingleElementDetails>();
    DBAdapter db=new DBAdapter(this);
    String category, description;
    String data;
    String data1;
    GridView gridview;
    Button  menu;

    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.homepage);

        menu=(Button)findViewById(R.id.menus);

        menu.setOnClickListener(new OnClickListener() {
            public void onClick(View v)
            {
                gridview=(GridView)findViewById(R.id.gridview);
                allElementDetails.clear();
                db.open();
                long id;
                //id=db1.insertTitle1(category, description,r_photo);
                Cursor cursor = db.getAllTitles1();
                while (cursor.moveToNext())
                {
                    SingleElementDetails single=new SingleElementDetails();
                    single.setCateogry(cursor.getString(1));
                    single.setDescription(cursor.getString(2));
                    single.setImage(cursor.getBlob(3));
                    allElementDetails.add(single);
                }
                db.close();
                CustomListAdapter adapter=new CustomListAdapter(HomePage.this,allElementDetails);
                gridview.setAdapter(adapter);
            }
        });
    }
}

My customListAdapter:

import java.io.ByteArrayInputStream;
import java.util.ArrayList;

import android.content.Context;
import android.graphics.Bitmap;
import android.graphics.BitmapFactory;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.widget.BaseAdapter;
import android.widget.ImageView;
import android.widget.TextView;

public class CustomListAdapter extends BaseAdapter {
    private  ArrayList<SingleElementDetails> allElementDetails;

    private LayoutInflater mInflater;

    public CustomListAdapter(Context context, ArrayList<SingleElementDetails> results) {
        allElementDetails = results;
        mInflater = LayoutInflater.from(context);
    }

    public int getCount() {
        return allElementDetails.size();        
    }

    public Object getItem(int position) {
        return allElementDetails.get(position);
    }

    public long getItemId(int position) {
        return position;
    }

    public View getView(int position, View convertView, ViewGroup parent) 
    {
        convertView = mInflater.inflate(R.layout.listview1, null);
        ImageView imageview = (ImageView) convertView.findViewById(R.id.image);
        TextView textview = (TextView) convertView.findViewById(R.id.category_entry);
        TextView textview1 = (TextView) convertView.findViewById(R.id.description_entry);
        textview.setText(allElementDetails.get(position).getCategory());
        textview1.setText(allElementDetails.get(position).getDescription());

        byte[] byteimage=allElementDetails.get(position).getImage();
        ByteArrayInputStream imageStream = new ByteArrayInputStream(byteimage);
        BitmapFactory.Options op=new BitmapFactory.Options();
        op.inSampleSize=12;
        Bitmap theImage= BitmapFactory.decodeStream(imageStream,null,op);
        imageview.setImageBitmap(theImage);
        return convertView;
    }
}
