Short answer:
<EditTextPreference
android:key="distance_units_m"
android:title="Distance"
android:summary="Summary"
android:dialogTitle="title"
android:numeric="integer"
android:maxLength="4"
android:hint="Enter distance (max 9999)" />
"This EditText can be modified [...] through XML by setting any
EditText attributes on the EditTextPreference."
Full answer:
When using the dialogLayout attribute, maybe a special android:id
identifier is required like the ids that must be used in ListActivity
or TabActivity.
Plus the documentation warns us about that attribute, as for the
layout attribute (use the widgetLayout attribute instead).
