Why SwitchPreference is not showing animation when switching from on to off & vice versa?

Question

I\'ve made a SwitchPreference for my app\'s preferences.

The problem is that the SwitchPreference is not showing animation whe

Answer 1

Causes

I noticed that a few different things could cause the animation to go missing for my SwitchPreference objects:

1. if the SwitchPreference is the very first Preference in the settings activity.

2. if I extend the SwitchPreference and use that instead (post describing a similar problem).

Fixes

To avoid the first problem, I created a DummyPreference class which I used as the first Preference in the PreferenceScreen instead. Examples below.

DummyPreference.java

public class DummyPreference extends Preference
{
    public DummyPreference(Context context,AttributeSet attrs)
    {
        super(context,attrs);
    }

    @Override
    public View getView(View convertView,ViewGroup parent)
    {
        View v = new View(getContext());
        v.setVisibility(View.GONE);
        return v;
    }
}

pref_whatever.xml

To avoid the second problem, I had to just resort to using android's plain old Preference classes in the XML, and I moved any extra logic needed into the Activity or Fragment containing the Preference objects.

I know this is an old post. I'm just hoping that it may help someone else in the future.
