Интеграция фрагментирования в фрагмент ⇐ Android

[Anonymous]

Я искал, но не нашел подходящий ответ на мой вопрос. Я совершенно новичок в Android Dev и пытаюсь выучить образцы броска. У меня есть 2 образца, которые я хочу собрать. Оба работают отлично, отдельно. /www.androidhive.info/2013/11/android-sl ... ion-рующих Пример Androi dev. < /p> Один из пунктов меню является общим. В общем, я хочу иметь видимые 3 вкладка. Настолько, что я хочу интегрировать GeneralFargment2 в GeneralFragment, поэтому у нас есть слайд -меню, и для каждого из пунктов меню различаются вкладки. Надеюсь, что вы, ребята, сможете мне помочь. public class GeneralFragment extends Fragment {
