为什么我的listview显示的是一串数字而不是内容？

Question

//这只是initviews的部分代码
@Override
    public void initViews(View view) {
        toolbar = view.findViewById(R.id.mine_toolbar);
        mListView = view.findViewById(R.id.mine_listview);
        mineLoginRl = view.findViewById(R.id.mine_login_rl);
        mImageView = view.findViewById(R.id.mine_circleImageView);
        tvName = view.findViewById(R.id.tv_username);

        iniToolbar();

        mImageView.bringToFront();

        setAdapterMineOrder();


//给listview添加内容的函数

private void setAdapterMineOrder(){
        ArrayList<String> strList = new ArrayList<>();
        strList.add("帮助中心");
        strList.add("我的收藏");
        strList.add("个人资料");
        ArrayList<Integer> ivList = new ArrayList<>();
        ivList.add(R.mipmap.bzzx);
        ivList.add(R.mipmap.wdsc);
        ivList.add(R.mipmap.wdzl);
        ArrayList<HashMap<String , Object>> listItem = new ArrayList<HashMap<String, Object>>();

        for (int i = 0; i <strList.size() ; i++) {
            HashMap<String , Object> map = new HashMap<>();
            map.put("textcontext" , strList.get(i));
            map.put("ivdrawable" , ivList.get(i));
            listItem.add(map);
        }
        String[] from  = {"textcontext" , "ivdrawable"};
        int[] to ={R.id.mine_item_img , R.id.mine_item_text};
        mSimpleAdapter = new SimpleAdapter(getActivity(),listItem ,
                R.layout.more_itemlist , from , to){
            @Override
            public View getView(int position, View convertView, ViewGroup parent) {
                return super.getView(position, convertView, parent);
            }
        };
        mListView.setAdapter(mSimpleAdapter);
        mSimpleAdapter.notifyDataSetChanged();
    }

得到的listview就是这样的

你的form 和 to 的对应关系应该搞反了，那些显示数字应该是图片的id 

没看到你的布局代码，看你id名 R.id.mine_item_img ，猜测这个对应的是ImageView

 

 String[] from  = {"textcontext" , "ivdrawable"};

//int[] to ={R.id.mine_item_img , R.id.mine_item_text};

int[] to ={R.id.mine_item_text , R.id.mine_item_img};
