Android - 为什么这告诉我“尚未创建内容视图"? [英] Android - why is this telling me "Content view not yet created"?

问题描述

这是在数据库中的片段上填充列表视图:

This is a populating a listview on a fragment from a database:

public View onCreateView(LayoutInflater inflater, ViewGroup container,
           Bundle savedInstanceState) {

            LinearLayout Layout5 = (LinearLayout) inflater.inflate(R.layout.tab_frag5_layout, container, false);

            Cursor allBands;
            MyDatabase db;

            Context ctx = (Context)TabFragment5.this.getActivity();


            db = new MyDatabase(ctx);
            allBands = db.getBands();


            ListAdapter adapter = new SimpleCursorAdapter (ctx, 
                    R.layout.listelement, 
                    allBands, 
                    new String[] {"BandName"},  
                    new int[] {R.id.text15});

            getListView().setAdapter(adapter);  

            return Layout5;

         }

为什么这会在 logcat 上显示尚未创建内容视图"?当片段打开时程序强制关闭...

Why is this giving me the "Content view not yet created" On logcat? the program forces close when the fragment opens...

推荐答案

我通过将适配器和 getListview 移动到 onActivityCreated(...) 解决了这个问题.

I solved it by moving the adapter and the getListview to onActivityCreated(...).

onCreateView 只是膨胀并返回布局.

onCreateView just inflates and returns the layout.
