PreferenceActivity and theme not applying

Hi all I have set the theme in the manifest file like this:

android:theme="@android:style/Theme.Light"

But I have a problem in the Preferences Activity, in the main preferences the theme shows ok, but if I get to a sub preference, the theme gets messy, it is not white as it should, it is all dark, and the font is black so you can't see much, and when I start clicking on any items they will get sometimes white as they should but revert to black soon after. This is only happens on 2.1, in both the real device and emulator. Tested on the emulator running 1.6 and it was working correctly. Here is part of the code of the preferences xml file:

<?xml version="1.0" encoding="utf-8"?>
<PreferenceScreen
    xmlns:android="http://schemas.android.com/apk/res/android">
    <PreferenceScreen
        android:title="@string/account">
        <CheckBoxPreference
            android:key="enable_account"
            android:title="@string/account_use"
            android:summary="@string/account_summ" />
        <EditTextPreference
            android:key="username"
            android:title="@string/login"
            android:dependency="enable_account"
            android:summary="@string/login_summ" />
        <EditTextPreference
            android:key="password"
            android:title="@string/password"
            android:dependency="enable_account"
            android:summary="@string/password_summ"
            android:password="true" />
    </PreferenceScreen>

And here is a screenshot:

At last i found out how to change theme of "PreferenceActivity" programmatically(via java code)

To change theme just do like this:

        @Override
        public void onCreate(Bundle savedInstanceState) {
        setTheme(R.style.Holo_Theme_Light);
        super.onCreate(savedInstanceState);
        }

Always call setTheme(R.style.yourtheme); method before super.onCreate(savedInstanceState); method. By doing this it will produce result as shown below.

enter image description here

That's all.

If yo call setTheme(R.style.yourtheme); method after super.onCreate(savedInstanceState); method it will produce result as shown below.

Note: Themes are not recognize by nested PreferenceScreen. To apply theme to that nested PreferenceScreen you have to make an another PreferenceActivity for that nested PreferenceScreen and call setTheme(R.style.yourtheme); method there.

This does appear to be a bug. See http://code.google.com/p/android/issues/detail?id=4611
