在listview中显示两个arraylist的活动

如何在listview中设置两个数组列表？我只能设置一个arraylist

        String[] captionArray = (String[]) data.toArray(
                new String[data.size()]);
        String[] rateArray = (String[]) rate.toArray(
                new String[rate.size()]);
        R.layout.order_list,R.id.itemname, captionArray));

设置列表适配器

     orderAdapter = new OrderAdapter(
                OrderActivity.this, R.layout.order_list,
                captionArray);

客户列表适配器

        setListAdapter(orderAdapter);

        return ;
    }

回复意见

         private class OrderAdapter extends BaseAdapter {
        String[] items;

        public OrderAdapter(Context context, int textViewResourceId,
                String[] items) {
            this.items = items;
        } 

膨胀

        public View getView(final int POSITION, View convertView,
                ViewGroup parent) {

            TextView tvNumber,tvName,tvRate;
            EditText etQty,etRemarks;

            View view = convertView;

将构造函数更改为接受两个ArrayList并将其存储在适配器中：

            if (view == null) {
                LayoutInflater vi = (LayoutInflater) getSystemService(Context.LAYOUT_INFLATER_SERVICE);
                view = vi.inflate(R.layout.order_list, null);

            } 
                tvName = (TextView) findViewById(R.id.itemname);
            tvRate = (TextView) findViewById(R.id.itemrate);

            tvName.setText(data.get(POSITION));
            tvRate.setText(rate.get(POSITION));


            return view; 
        }


        public int getCount() {
            // TODO Auto-generated method stub
            return items.length;
        }


        public Object getItem(int position) {
            // TODO Auto-generated method stub
            return position;
        }


        public long getItemId(int position) {
            // TODO Auto-generated method stub
            return position;
        }
    }

}

此外，您还应该在适配器和列表视图上观看此操作，以加快速度

getView（）

List firstList=new ArrayList（）；
List secondList=new ArrayList（）；
名单第三名；
添加（“…”）；
第二个列表。添加（“…”）；
thirdList=新阵列列表（firstList）；
第三个列表addAll（第二个列表）；

将

thirdList

应用于适配器。

使用从这两个ArrayList创建的第三个ArrayList。将两个ArrayList的内容添加到第三个ArrayList，并在程序中使用第三个ArrayList。

            if (view == null) {
                LayoutInflater vi = (LayoutInflater) getSystemService(Context.LAYOUT_INFLATER_SERVICE);
                view = vi.inflate(R.layout.order_list, null);

            } 
                tvName = (TextView) findViewById(R.id.itemname);
            tvRate = (TextView) findViewById(R.id.itemrate);

            tvName.setText(data.get(POSITION));
            tvRate.setText(rate.get(POSITION));


            return view; 
        }


        public int getCount() {
            // TODO Auto-generated method stub
            return items.length;
        }


        public Object getItem(int position) {
            // TODO Auto-generated method stub
            return position;
        }


        public long getItemId(int position) {
            // TODO Auto-generated method stub
            return position;
        }
    }

}

private class OrderAdapter extends BaseAdapter {
    ArrayList<String> data;
    ArrayList<String> rate;

    public OrderAdapter(Context context, ArrayList<String> data, ArrayList<String> rate) {
        this.data = data;
        this.rate = rate;
    } 

    // Use the same getView(), for now

    public int getCount() {
        return data.size(); // rate must be the same size as data!
    }

    public String getItem(int position) {
        return data.get(position);
    }

 orderAdapter = new OrderAdapter(this, data, rate);

List<String> firstList = new ArrayList<String>();
List<String> secondList = new ArrayList<String>();
List<String> thirdList;
firstList.add("...");
secondList.add("...");

thirdList = new ArrayList<String>(firstList);
thirdList.addAll(secondList);
