How to get an Android ListPreference defined in Xml whose values are integers?
android, android-preferences
Solution
My understanding is that ListPreference can only work with string arrays. You'll have to use getString() and convert to integer yourself. See http://code.google.com/p/android/issues/detail?id=2096 for the bug report on this. It doesn't look like Google plans to extend ListPreference to handle anything but strings.
Also: You'll need to store the preference as a string too. Otherwise, your preferences activity will crash when it starts up and tries to read a string value.
Problem
Is it possible to define a ListPreference in Xml and retrieve the value from SharedPreferences using getInt? Here is my Xml: ``` <ListPreference android:key="@string/prefGestureAccuracyKey" android:title="@string/prefGestureAccuracyTitle" android:summary="@string/prefGestureAccuracyDesc" android:entries="@array/prefNumberAccuracyLabels" android:entryValues="@array/prefNumberAccuracyValues" android:dialogTitle="@string/prefGestureAccuracyDialog" android:persistent="true" android:defaultValue="2" android:shouldDisableView="false" /> ``` And I want to get the value with something like: int val = sharedPrefs.getInt(key, defaultValue). At the moment I have to use getString and parse the result.
