我无法在SlidingMenu片段中单击ListView，不会出现布局
为什么我可以klik listview（ReviewFragment）和它的布局没有出现，我有SlidingMenu，当我点击我的评论菜单布局没有出现，请有，也许在我的代码我有错误，
这是我的ReviewFragment.java：

在此之前，请帮助我，因为它已接近校园的截止日期
编辑：
不要像我之前建议的那样改变这个：
case 3: listfragment = new ReviewFragment(); break;
切换到此后只更改代码：
if (fragment != null) { FragmentManager fragmentManager = getFragmentManager(); fragmentManager.beginTransaction() .replace(R.id.frame_container, fragment).commit(); // update selected item and title, then close the drawer mDrawerList.setItemChecked(position, true); mDrawerList.setSelection(position); setTitle(navMenuTitles[position]); mDrawerLayout.closeDrawer(mDrawerList); } else if (listfragment != null) { FragmentManager fragmentManager = getFragmentManager(); fragmentManager.beginTransaction() .replace(R.id.frame_container, listfragment).commit(); } else { // error in creating fragment Log.e("MainActivity", "Error in creating fragment"); }
