using image button, in each listview item row and

Question

I am using image button, in each listview item row and trying to start a new activity using Button onClick listener, but getting:- the source attachment does not contain source for the ComponentName.class

package com.example.androidhive;

public class LazyAdapter extends BaseAdapter {

protected static final Context Context = null;
private Activity activity;
private ArrayList<HashMap<String, String>> data;
private static LayoutInflater inflater=null;
public ImageLoader imageLoader; 

public LazyAdapter(Activity a, ArrayList<HashMap<String, String>> d) {
    activity = a;
    data=d;
    inflater = (LayoutInflater)activity.
  getSystemService(Context.LAYOUT_INFLATER_SERVICE);
    imageLoader=new ImageLoader(activity.getApplicationContext());
}

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

public Object getItem(int position) {
    return position;
}

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

public View getView(int position, View convertView, ViewGroup parent) {
    View vi=convertView;
    if(convertView==null)
        vi = inflater.inflate(R.layout.list_row, null);

    TextView title = (TextView)vi.findViewById(R.id.title); 
    TextView artist = (TextView)vi.findViewById(R.id.description); 
    TextView duration = (TextView)vi.findViewById(R.id.cost); 
    TextView regular = (TextView)vi.findViewById(R.id.regular); 
    TextView small = (TextView)vi.findViewById(R.id.small); 
    TextView large = (TextView)vi.findViewById(R.id.large); 
    ImageView thumb_image=(ImageView)vi.findViewById(R.id.item_image); 
    ImageButton btn_add=(ImageButton)vi.findViewById(R.id.addorder);





    HashMap<String, String> song = new HashMap<String, String>();

    song = data.get(position);

    // Setting all values in listview
    title.setText(song.get(CustomizedListView.KEY_TITLE));
    artist.setText(song.get(CustomizedListView.KEY_DESC));
    duration.setText(song.get(CustomizedListView.KEY_COST));
    regular.setText(song.get(CustomizedListView.KEY_REGULAR));
    small.setText(song.get(CustomizedListView.KEY_SMALL));
    large.setText(song.get(CustomizedListView.KEY_LARGE));

    imageLoader.DisplayImage(song.get(CustomizedListView.KEY_THUMB_URL), thumb_image);

    btn_add.setOnClickListener(new OnClickListener()
    {
        public void onClick(View v)
        {
           Intent intent = new Intent(Context, FinalOrder.class);
           startActivity(intent);
        }
    });

    return vi;

   }

protected void startActivity(Intent intent) {
    // TODO Auto-generated method stub

}

  }

Answer 1

In your custom adapter as mentioned in your link, In the getView method add click listner to image button So you can handle click of your image buttons in the custom adapter and if you want to send data between activities you can also send it in that click listner on based of position on click

myImageButton.setOnClickListener(new OnClickListener()
            {
                public void onClick(View v)
                {
Intent intent = new Intent(Context, nextactivity.class);
intent.putExtra("value",ValueArray[position]);
startActivity(intent);
})};

Answer 2

your adapter is returning you a view. right?

now in your onitemclickListener

ImageButton myImageButton = (ImageButton) view.findViewById(R.id.addorder);

now apply onclicklistener on your myImageButton.
