    <p>In a xml, I am having <code>LinearLayout</code>. Inside that I am using an <code>ExpandableListView</code>. Every expand item contain just one view which is a <code>GridView</code>. A <code>GridView cell</code> compose with three UI components which are <code>ImageView</code>, <code>TextView</code> and a <code>Button</code>. How I have got control about those three UI components is as follow,</p> <pre><code>public View getView(final int position, View convertView, ViewGroup parent) { LayoutInflater layoutInflater = (LayoutInflater) imageAdapterContext.getSystemService(Context.LAYOUT_INFLATER_SERVICE); if (convertView == null) { convertView = layoutInflater.inflate(R.layout.single_grid_item, null); viewHolder = new ViewHolder(); viewHolder.singleImageView = (ImageView) convertView.findViewById(R.id.singleGridItem_imageView); viewHolder.singleTextView = (TextView) convertView.findViewById(R.id.singleGridItem_textView); viewHolder.singleDownloadButton = (Button) convertView.findViewById(R.id.singleGridItem_download_button); } } // ViewHolder is a static nested inner class </code></pre> <p>Things are working prety fine. That means each cell identify as different cells. They have different images, and appropriate <code>TextView</code> labels and also <code>Button</code> click event also working fine. For the button click I have used a downloading with a <code>ProgressDialog</code>. That also working fine. What I want is disable the <code>Button</code> when the downloading in progress. Downloading happening in a seperate <code>AsyncTask</code> class. Please tell me how can I disable the button which user has clicked for downloading.</p>

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.
