Change the summary of a ListPreference with the new value (Android)

Question

How can I modify the summary of a ListPreference to the new \"Entry\" string selected by the user (not the entry value)

I suppouse its with setOnPreferenceChangeList

Answer 1

i solved this problem with another and simple solution (https://gist.github.com/brunomateus/5617025):

public class ListPreferenceWithSummary extends ListPreference{

public ListPreferenceWithSummary(Context context, AttributeSet attrs) {
    super(context, attrs);
}

public ListPreferenceWithSummary(Context context) {
    super(context);
}

@Override
public void setValue(String value) {
    super.setValue(value);
    setSummary(value);
}

@Override
public void setSummary(CharSequence summary) {
    super.setSummary(getEntry());
}
}

This worked very fine on my GirgerBeard device. Even when is the first time running your app. Don't forget to provide default value on your xml prefence:

android:defaultValue="default value"

and set default values on your PreferenceActivity or PrefenceFragment:

 PreferenceManager.setDefaultValues(this, R.xml.you pref file, false);
