写侧滑界面有两个报错

break;

break;
}
ft.replace(R.id.fragment_layout,fragment);
ft.commit();
mDrawer_layout.closeDrawer(mMenu_layout_left);
}
}
}
第一个是说类型不兼容，FirstFragment类不能转变成Fragement
这是我的FirstFragment类
public class FirstFragment extends Fragment {
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle saveInstance){
return inflater.inflate(R.layout.fragment_first,null);
}
}
还有一个是 mDrawer_layout.closeDrawer(mMenu_layout_left);
无法resovle这个方法
是不是你的FirstFragment 继承的父类的包导错了？因为你的Listleft 中fragment导的包是V4的。
你的closeDrawer方法应该是DrawerLayout的方法。而你的 mDrawer_layout 明显是LinearLayout
