Click ImageView within a ListView ListItem and get the position?

Currently, when the ListItem is clicked I grab its position and pass it to my StopsScheduleActiviy. I would like to detect when the ImageView of that ListItem is clicked so that I can launch my MapActivity instead and pass it the position.

Basically: Click the ImageView launch MapsActivity, otherwise click anywhere else on ListItem launch StopsScheduleActivity. In Both cases I need the position. How can I do this?

Here is my current onItemClick listener.

@Override
public void onItemClick(AdapterView<?> parent, View view, int position, long id) {

    Intent myIntent = new Intent(this, StopsScheduleActivity.class);
    myIntent.putExtra("stop", stops.get(position));

    startActivity(myIntent);

    Log.i("Winnipeg Bus", "Stop item #" + id + " clicked.");
}

Here is my ListView with a map for an ImageView that I want to listen to for clicks. Thanks!

@Override
public View getView(int position, View convertView, ViewGroup parent) {
    System.out.println("getView " + position + " " + convertView);
    ViewHolder holder = null;

    if (convertView == null) {
        convertView = LayoutInflater.from(conText).inflate(
            R.layout.gridgoggle, parent, false);
        holder = new ViewHolder();
        convertView.setTag(holder);

    } else {
        holder = (ViewHolder) convertView.getTag();
    }

    holder.imageView1.setImageResource(Integer.parseInt((mData
        .get(position).get("image"))));

    holder.imageView1.setId(position);
    holder.imageView1.setOnClickListener(new OnClickListener() {
        public void onClick(View v) {
            int id = v.getId();
            //here id is position.
            Intent myIntent = new Intent(this, StopsScheduleActivity.class);
            myIntent.putExtra("stop", id);
            startActivity(myIntent);
        }
    });
    return convertView;
}

In you Custom Adapter getView() method , when you are init the ImageView. Add position as a tag for image view. So each time when new ImageView will appear it will hold its position in his tag. Then just add the OnClickListener() in getView().

OnClickListener(View view) contains the view which was clicked by user. So when user will click any image view in the list. Then it will be passed to OnClickListener(View view) as a clicked view. And we know that our ImageView contains the position as a tag. So the tag can tell us that this ImageView is for ? position. :)

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

    ImageView imageView = (ImageView) convertView.findViewById(R.id.videoListImage);
    imageView.setTag(new Integer(position));
    imageView.setOnClickListener(new OnClickListener() {
            
        @Override
        public void onClick(View view) {
            Toast.makeText(mContext, "ImageView clicked for the row = "+view.getTag().toString(), Toast.LENGTH_SHORT).show();
        }
    });

    return convertView;
}

You will get the clicked ImageView position.

In three simple steps:

1 In your adapter method getView(int position, View convertView, ViewGroup parent):

ImageView imageview =(ImageView) convertView.findViewById(R.id.imageView);
imageview.setTag(new Integer(position));

2 In layout.xml add the method onClick() on the ImageView

3 implements onClick() method and retrieves the index by view.getTag()

For ImageView's Click You have to make a custom adapter for your listview.

And in adpater's getView() method just write a imageView's onClick(), And start your new activity from that imageview's onClick().

For custom list just look at this tutorial Android Series: Custom ListView items and adapters ..
