地图和列表android

Question

如何将此List<Map<String,?>> items = new LinkedList<Map<String,?>>();存储到变量数组并创建其倍数。我是新手，我有点混淆我如何使用它。

我正在为listview创建节标题，这就是为什么我需要多个item，因为它是我的数据源，而我将生成的标题数量取决于我检索的项目类型。 / p>

这是我到目前为止所尝试的：

listView = (ListView)findViewById(R.id.listView2);
        items = new LinkedList<Map<String,?>>();

        // create our list and custom adapter
        SeparatedListAdapter adapter = new SeparatedListAdapter(this);
        int index = 0;
        String storeName = "";
        String d = handler.getStoreList().get(index).toString();
        for(int innerCounter = 0; innerCounter < handler.getItemList().size(); innerCounter ++) {
            //Items to display in the row
            String itemName = handler.getItemList().get(innerCounter).toString();
            String category = handler.getPriceList().get(innerCounter).toString();
            //this data is the storeName that should 
            //be the section header and be compared if change
            //of store is detected to create new header
            storeName = handler.getStoreList().get(innerCounter).toString();
            if (storeName.equals(d)){
                Log.i("Items", d);
                //add items if the storeName does change
                items.add(createItem(itemName, category));
            }
            else {
                // else if storeName change create a section and 
                // put the data inside
                adapter.addSection(d, new SimpleAdapter(this, items, R.layout.listview_format,   
                        new String[] { ITEM_TITLE, ITEM_CAPTION }, new int[] { R.id.item_list, R.id.list_complex_caption }));
                Log.i("Header", "Sucessfully create new header");
                // create new instance of items to for another checking
                List<Map<String,?>> items = new LinkedList<Map<String,?>>();
                items.add(createItem(itemName, category));
                Log.i("Items", d);
                // change the header
                d = handler.getStoreList().get(index+1).toString();
                adapter.addSection(d, new SimpleAdapter(this, items, R.layout.listview_format,   
                        new String[] { ITEM_TITLE, ITEM_CAPTION }, new int[] { R.id.item_list, R.id.list_complex_caption }));
            }

        }
        listView.setAdapter(adapter); 
        listView.setOnItemClickListener( new OnItemClickListener() {
            public void onItemClick(AdapterView<?> arg0, View v, int position ,
                    long id) {
                HashMap<String, String> mymap = (HashMap<String, String>) arg0.getItemAtPosition(position);
                String selectedItem =mymap.get(ITEM_TITLE);
                intent = new Intent(TechiesActivity.this,ItemInfoActivity.class);
                intent.putExtra("key", selectedItem);
                intent.putExtra("className", "Techies");
                startActivity(intent);          
            }
        });
    }
