Show a true modal dialog box without button
<p>The following code will produce a truely model dialog box, with close button. Truely model means, when you click on the area other than dialog box, the dialog box will remain active and will not close.</p>

<pre><code>AlertDialog alert = builder
    .setCancelable(false)
    .setPositiveButton(context.getResources().getString(R.string.about_close), null)
    .create();
alert.show();
</code></pre>

<p>The following will produce a dialog box without close button. When you click on the area other than dialog box, the dialog box will be closed.</p>

<pre><code>AlertDialog alert = builder
    .setCancelable(false)
    .create();
alert.show();
</code></pre>

<p>Is there any way I can have a truely model dialog, without button?</p>
