How make a ListPreference with checkbox
How can I create a ListPreference
with checkbox
?
I know how to use ListPreference
开发者_StackOverflow, but I need multiple selection like in Alarm application on "repeat" preference.
like this screenshot:
Since API 11 you can use MultiSelectListPreference
String[] selections = {"selection1","Selection2"};
Set<String> selectionSet = new HashSet<String>();
selectionSet.addAll(Arrays.asList(selections));
MultiSelectListPreference multiSelectPref = new MultiSelectListPreference(this);
multiSelectPref.setKey("multi_pref");
multiSelectPref.setTitle("Multi Select List Preference");
multiSelectPref.setEntries(selections);
multiSelectPref.setEntryValues(selections);
multiSelectPref.setDefaultValue(selectionSet);
getPreferenceScreen().addPreference(multiSelectPref);
Use, MultiSelectListPreference
<MultiSelectListPreference
app:defaultValue="@array/watermark_entries_view"
app:dialogTitle="Select Watermark Type"
app:entries="@array/watermark_entries_view"
app:entryValues="@array/watermark_entries_values"
app:key="mode_repeat"
app:summary="Enable Watermark"
app:title="Watermark" />
There is no built-in preference for that AFAIK. ListPreference
is single-select only.
You could create your own custom Preference
class, though, by extending DialogPreference
.
For boolean values you must use a SwitchPreference, as follows:
<SwitchPreference
android:defaultValue="true"
android:key="example_switch"
android:summary="@string/pref_description_social_recommendations"
android:title="@string/pref_title_social_recommendations" />
