Android Preferences: How to load the default values when the user hasn't used the preferences-screen?

Question

I am using a PreferenceActivity to let the user set some values. I am feeding it the xml file with the defined preferences.

I have set all the android:defaultV

Answer 1

For example extending DialogPreference I do this:

@Override
protected void onSetInitialValue(boolean restore, Object defaultValue) {
    super.onSetInitialValue(restore, defaultValue);

    if (restore) {
        mValue = shouldPersist() ? getPersistedString(mDefault) : mDefault;
    } else {
        mValue = mDefault;
    }
}

mDefault can be:

• mContext.getResources().getString(attrs.getAttributeResourceValue(androidns,"defaultValue", 100));
• something you have indexed in R.
