Black screen in inner preferenceScreen

Question

My PreferenceActivity contains a nested PreferenceScreen in another PreferenceScreen and I\'m applying a theme to my PrefenceAct

Answer 1

Macarse's answer is perfect, I was searching for classic white background so I changed this line in his answer:

a.getDialog().getWindow().setBackgroundDrawableResource(R.drawable.background);

to:

a.getDialog().getWindow().setBackgroundDrawableResource(android.R.color.white);

and it works nicely.
