I added 3 switch preference in a PreferenceCategory programmatically.
<?xml version="1.0" encoding="utf-8"?>
<PreferenceScreen xmlns:android="http://schemas.android.com/apk/res/android"
android:persistent="true">
<PreferenceCategory
android:key="my_key"
android:title="TEST" />
</PreferenceScreen>
Here is the code for adding switch preferences.
PreferenceGroup preferenceGroup = (PreferenceGroup) findPreference("my_key");
for (int i = 0; i < 3; i++) {
SwitchPreference switchPreference = new SwitchPreference(getActivity());
switchPreference.setTitle(title);
switchPreference.setKey(key);
switchPreference.setDefaultValue(true);
switchPreference.setChecked(true);
preferenceGroup.addPreference(switchPreference);
}
The screen shows like below. They're all unchecked. Does anyone know how to fix it? Thanks a lot!
Fixed by setting the default value programmatically.
