I have a preference setting that I need to customize so that the preference
will only accept ints.
The way I understand this is that I specify the android:dialogLayout with
the name of my custom layout:
<EditTextPreference
android:key="distance_units_m"
android:title="Distance"
android:summary="Summary"
android:dialogTitle="title"
android:dialogLayout="@layout/preferences_distance"
/>
This is my customized EditText: it only accepts numbers up to 9999.
<?xml version="1.0" encoding="UTF-8"?>
<EditText
xmlns:android="http://schemas.android.com/apk/res/android";
android:numeric="integer"
android:maxLength="4"
android:hint="Enter distance (max 9999)"
/>
This works and shows up correctly.
I do not do anything else and my activity simply loads the XML resource.
The problem is that if I do specify my custom editor the data from the user
is not automatically saved anymore.
(Removing only the line with the dialogLayout makes it save as expected, so
that is correct)
Do I have to specify anything else in the XML to get it saved? Or do I now
have to program this?
(I would have thought that behind the scenes, the editor (whether it is
custom or not) is somehow created by a factory, and then all invocations
happen on the created object, thus making it no difference how the look/feel
of the custom editor is. But that is obviously not how it is done)
Any pointers?
