Я получил Actionbar и некоторые фрагменты. Проблема - мой домашний экран. С левой стороны находится обзорный фрагмент, а с правой стороны фрагмент. Мой TabListener является динамическим, поэтому я хочу установить вес моего макета программно. Всякий раз, когда я пытаюсь получить Layoutparams моего LinearLayout, я получаю ClassCastException:

12-22 16:00:37.620: W/System.err(7235): java.lang.ClassCastException: android.widget.FrameLayout$LayoutParams cannot be cast to android.widget.LinearLayout$LayoutParams

            LinearLayout myView = (LinearLayout)this.getView().findViewById(R.id.container_found_list_overview);
            Log.d("found container", ""+(myView != null));
            try{
                LayoutParams lp = (LayoutParams) myView.getLayoutParams();
                lp.weight = 1;
                lp.width = 0;
                myView.setLayoutParams(lp);
