    <p>It seems to be there is no easy way to get an Alert dialog to return a simple value.<br> This code <strong>does not work</strong> (the <em>answer</em> variable cannot be set from within the listener, in fact it does not even compile)</p> <pre class="lang-js prettyprint-override"><code>public static boolean Confirm(Context context) { boolean answer; AlertDialog dialog = new AlertDialog.Builder(context).create(); dialog.setTitle("Confirmation"); dialog.setMessage("Choose Yes or No"); dialog.setCancelable(false); dialog.setButton(DialogInterface.BUTTON_POSITIVE, "Yes", new DialogInterface.OnClickListener() { public void onClick(DialogInterface dialog, int buttonId) { answer = true; } }); dialog.setButton(DialogInterface.BUTTON_NEGATIVE, "No", new DialogInterface.OnClickListener() { public void onClick(DialogInterface dialog, int buttonId) { answer = false; } }); dialog.setIcon(android.R.drawable.ic_dialog_alert); dialog.show(); return answer; } </code></pre> <p>NOTE: It is important that the method is self contained, i.e., it does not depend on variables or constructs external to it. Just call it and get your answer, true or false.</p> <p>So, what to do? This simple wish of returning <strong>true</strong> or <strong>false</strong> seems to be much more complicated than it deserves.</p> <p>Also, the setButton method has the form:</p> <pre class="lang-js prettyprint-override"><code>dialog.setButton(int buttonId, String buttonText, Message msg) </code></pre> <p>But it is not clear how to use it, where is the meesage sent to, to whom, which handler is used?</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.
