Android ProgressBar in ListView while using DownloadManager

Question

I have a ListView in which each item represents a PDF file. When the user clicks on an item, the application must download the file on external storage. Now the download doe

Answer 1

I'd use an AsyncTask for that, and make the wheel appear / disappear in onPreCreate & onPostCreate

private class MyDownloader extends AsyncTask{

    @Override
    protected void onPreExecute() {
        loader.setVisibility(View.VISIBLE);
    }

    @Override
    protected File doInBackground(String... params) {
        //Download and save file here, and return the result, which will be fed into the onPostExecute method
        return file;
    }

    @Override
    protected void onPostExecute(File file) {
        super.onPostExecute(file);
        loader.setVisibility(View.GONE);
    }
}

Then start the task with new MyDownloader().execute("linktopdf"); or something like that (what you put in .execute will be fed into the doInBackground method)
