Adding a ProgressBar to a ListView/OnClick called a single time

Question

The idea is to have a list of items where after clicking an item, a ProgressBar will slowly fill as the task is completed. For example, picture a list of files, with a Download

Answer 1

Did you try setting click listener to download item in adapter itself like following:

@Override
public View getView(int position, View convertView, ViewGroup parent) {
    View row = convertView;
    if(row == null) {
        // Inflate
        Log.d(TAG, "Starting XML inflation");
        LayoutInflater inflater = (LayoutInflater) this.getContext().getSystemService(Context.LAYOUT_INFLATER_SERVICE);
        row = inflater.inflate(R.layout.download_list_item, parent, false);
        Log.d(TAG, "Finished XML inflation");
    }

    final DownloadItem item = mItems.get(position);

    ProgressBar downloadProgressBar = (ProgressBar) row.findViewById(R.id.downloadProgressBar);
    Button downloadButton = (Button) row.findViewById(R.id.downloadButton);

    downloadButton.setTag(item);
    downloadProgressBar.setMax(item.length);
    downloadProgressBar.setProgress(item.progress);

    downloadButton.setOnClickListener(new View.OnClickListener() {

        @Override
        public void onClick(View v) {
            new DownloadTask(DownloadArrayAdapter.this, item).execute();
        }
    });

    return row;
}
