    <p>I have grid containing images. On click of images, downloading of book starts. If the download is in progress and if i am clicking that image only the download getting started. Due to this the resultant file is corrupted. The downloading task has been put on the onClick event of image. I have tried to make first image clickable false then setEnable false. but both the way didn't work for me. The image click is working even download is in progress. Please guide. For details,Here is my codes:</p> <pre><code> public class GridViewAdapter extends BaseAdapter { ImageView imageView; private Context context; private int item; private LayoutInflater layoutInflater; GridViewAdapter(Context c, int griditem) { this.context = c; this.item = griditem; this.layoutInflater = (LayoutInflater) c .getSystemService(Context.LAYOUT_INFLATER_SERVICE); } @Override public int getCount() { return bank.size(); } @Override public Object getItem(int position) { return bank.get(position); } @Override public long getItemId(int position) { return position; } @Override public View getView(final int position, View convertView, ViewGroup arg2) { View grid; Display display = ((WindowManager) context .getSystemService(WINDOW_SERVICE)).getDefaultDisplay(); int orientation = display.getOrientation(); 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()); 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); if(targetDir.exists()){ downloadmark.setVisibility(View.VISIBLE); } imageView.setOnClickListener(new View.OnClickListener() { @Override public void onClick(View v) { if (!targetDir.exists()) { if (isInternetConnected()) { map.put(bank.get(position).getTitle(), progress); new DownloadPdfFile(GridDisplayActivity.this, bank .get(position).getPdfLink(), progress, downloadmark, imageView).execute(); } else { setAlertBox("You are not connected to Internet.

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.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
