Question

Can I inflate PreferenceScreen inside an alert dialog?

This is what I’ve tried:

final LayoutInflater factory = LayoutInflater.from(this);
final View myDialog = factory.inflate(R.xml.prefScr, null);
final Dialog dialog = new AlertDialog.Builder(this)
    .setTitle("This is Dialog")
    .setView(myDialog)
    .create();

this gives me exception:

android.view.InflateException: Binary XML file line #2: Error inflating class PreferenceScreen

I don’t think it is possible to use a PreferenceScreen outside of a PreferenceActivity like this…but here are a few alternatives:

1) Make the Activity appear as a dialog by using a style in your Manifest:

<activity
    android:name=".MyPrefsActivity"
    android:label=""
    android:theme="@android:style/Theme.Dialog">
</activity>

2) Use an AlertDialog as you currently are but inflate it with your own custom layout that has the same features as you PreferenceScreen does. Then you would have to manage the getting and setting of preferences manually.

3) Just use a PreferenceActivity with its own PreferenceDialog. This might not really be the same thing that you want, but using a PreferenceActivity will save you a lot of the work of manually handling all of your preferences.
