Should Views be reused in Preferences?

Question

I have an Android app in which I use Preferences. I am currently developing a custom Preference that uses a TimePicker for its View.

The method that is supposed to give Android the View to show is getView(View, ViewGroup). Its first parameter, View convertView contains a View to reuse if possible.

However, I was thinking of creating the TimePicker in the constructor and storing it in a field:

public class MyPreference {
    private TimePicker mTimePicker;

    public MyPreference(Context context, AttributeSet attrs) {
        super(context, attrs);
        mTimePicker = new TimePicker(context);
    }

    public View getView(View convertView, ViewGroup parent) {
        return mTimePicker;
    }
}

Are there any problems with this approach, or what would be better?
