How to get rid of "duplicated" background of the AlertDialog with android.R.style.Theme_DeviceDefault_Light_Dialog?
<p>My code:</p>

<pre><code>AlertDialog.Builder a = new AlertDialog.Builder(
main.this,
android.R.style.Theme_DeviceDefault_Light_Dialog);
a.setTitle("test");
a.setMessage("example");
a.show();
</code></pre>

<p>And getting this: cs405220.userapi.com/v405220863/955/ls7yj-dvVpE.jpg</p>

<p>Why background is duplicated and how to ged rid of it? (It happens not with android.R.style.Theme_DeviceDefault_Light_Dialog only)</p>
