Question

I’m having a ListView with my own custom adapter derived from a BaseAdapter. Each item in the ListView has sub items such as ImageView and TextView.

How can I know which one of these sub items the user clicked? Is it possible to attach a listener in the getView function for example, or could that be a problem?

Edit: Currently I have a onItemClick in the Activity which contains the ListView. Is there any good way to know which sub item in a specific item in the ListView which has been pressed by checking the params in the onItemClick.

@Override 
public void onItemClick(AdapterView<?> a, View v, int pos, long id) {
.

}

You can do it. You need to modify your getView method:

@Override
public View getView(final int position, View row, final ViewGroup parent) {
    ...     
    YourWrapper wrapper = null;
    if (row == null) {
        row = getLayoutInflater().inflate(R.layout.your_row, parent, false);
        wrapper = new YourWrapper(row);
        row.setTag(wrapper);
    } else {
        wrapper = (YourWrapper) row.getTag();
    }

    wrapper.yourSubView.setOnClickListener(new View.OnClickListener()   
    {               
    @Override
    public void onClick(View v) {
        // do something
    }
    ...
}
