Body
That can be achieved with the help of <a href="http://developer.android.com/reference/android/os/AsyncTask.html" rel="nofollow">AsyncTask</a> (an intelligent backround thread) and <a href="http://developer.android.com/reference/android/app/ProgressDialog.html" rel="nofollow">ProgressDialog</a> A ProgressDialog with indeterminate state would be raised when the AsyncTask starts, and the dialog is would be dismissed once the task is finished . Example code What the adapter does in this example is not important, more important to understand that you need to use AsyncTask to display a dialog for the progress. <pre><code>private class PrepareAdapter1 extends AsyncTask<Void,Void,ContactsListCursorAdapter > { ProgressDialog dialog; @Override protected void onPreExecute() { dialog = new ProgressDialog(viewContacts.this); dialog.setMessage(getString(R.string.please_wait_while_loading)); dialog.setIndeterminate(true); dialog.setCancelable(false); dialog.show(); } /* (non-Javadoc) * @see android.os.AsyncTask#doInBackground(Params[]) */ @Override protected ContactsListCursorAdapter doInBackground(Void... params) { cur1 = objItem.getContacts(); startManagingCursor(cur1); adapter1 = new ContactsListCursorAdapter (viewContacts.this, R.layout.contact_for_listitem, cur1, new String[] {}, new int[] {}); return adapter1; } protected void onPostExecute(ContactsListCursorAdapter result) { list.setAdapter(result); dialog.dismiss(); } } </code></pre>

Guidance

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.
