android - How to show PreferenceScreen within PreferenceFragment -
i new android , appreciate help. first question =d sorry giving 2 links , no images, have not enought reputation made question more clear
acording android api guides settings, using preferencefragment because developing android 3.0 (api level 11) , higher.
i want achieve effect shown @ figure 4 , 5 android api guides settings link.
on tablet emulator looks ok, on handset emulator (and real device) can not achieve it. instead "sound", "display", "storage", "battery"... preferencecategory (like "device" seems) followed options should in new screen (activity). in 1 screen.
here files, in advance
