Body
<p>I have defined the image view and the progress bar as final and sending these references to the AsyncTask where the magazine downloading activity is going, on click of image view. AsyncTask spawns multiple threads and that's how progress of each download can be updated.Code:</p> <pre><code> @Override public View getView(final int position, View convertView, ViewGroup arg2) { View grid; if (convertView == null) { grid = new View(context); grid = layoutInflater.inflate(item, null); } else { grid = (View) convertView; } final TextView title = (TextView) grid.findViewById(R.id.mgntitle); title.setText(bank.get(position).getTitle()); final ImageView imageView = (ImageView) grid .findViewById(R.id.thumbnail); imageView.setImageResource(R.drawable.icon); final ProgressBar progress = (ProgressBar) grid .findViewById(R.id.progress); final ImageView downloadmark = (ImageView) grid .findViewById(R.id.downloadmark); String pdfLink = bank.get(position).getPdfLink(); String filename = pdfLink.substring(pdfLink.lastIndexOf("/") + 1); final File targetDir = new File(fileLocation + filename); System.out.println("target file name " + targetDir); if (new File(fileLocation + filename).exists()) { if (!getPrefName(filename).equalsIgnoreCase("NA")) { downloadmark.setVisibility(View.VISIBLE); } } imageView.setOnClickListener(new View.OnClickListener() { @Override public void onClick(View v) { if (!targetDir.exists()) { map.put(bank.get(position).getTitle(), progress); new DoBackgroundTask(GridDisplayActivity.this, bank .get(position).getPdfLink(), progress, downloadmark, imageView, position) .execute(); } } }); imageView.setImageBitmap(BitmapFactory.decodeByteArray( bank.get(position).getCoverPages(), 0, bank.get(position) .getCoverPages().length)); return grid; } </code></pre>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
