Question

I have a HeaderView in my ListView. On clicking it, it hides the text and shows a spinner to fetch data from somewhere.

I want to disable the onClick after the first click so that he cannot call the fetch multiple times.

I tried v.setClickable(false) and v.setEnabled(false), but none of them worked.

Any ideas?

protected void onListItemClick(ListView l, View v, int position, long id) {
    super.onListItemClick(l, v, position, id);
    if (position == 0) {

            ProgressBar pb = (ProgressBar) v
                    .findViewById(R.id.refresh_progress);
            pb.setVisibility(View.VISIBLE);
            TextView tv = (TextView) v.findViewById(R.id.load);
            tv.setVisibility(View.GONE);
            v.setClickable(false);
            DownloadTask dt = new DownloadTask(v, "Old Message");
            dt.execute();

        } 
}

Probably best to just track the fact that you have already done/started a fetch with a member var in your activity and then test it in your OnClick handler

private boolean wasFetchStarted = false;

protected void onListItemClick(ListView l, View v, int position, long id) {
    super.onListItemClick(l, v, position, id);
    if (position == 0 && ! wasFetchStarted) {
            wasFetchStarted = true;
            ProgressBar pb = (ProgressBar) v
                    .findViewById(R.id.refresh_progress);
            pb.setVisibility(View.VISIBLE);
            TextView tv = (TextView) v.findViewById(R.id.load);
            tv.setVisibility(View.GONE);
            v.setClickable(false);
            DownloadTask dt = new DownloadTask(v, "Old Message");
            dt.execute();

        } 
}
