Activity to display two arraylist in listview

  public class OrderActivity extends ListActivity {
    ArrayList<String> data,rate;
    OrderAdapter orderAdapter;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        // TODO Auto-generated method stub
        super.onCreate(savedInstanceState);
        setContentView(R.layout.order);
        Bundle extras = getIntent().getExtras(); 
        data = extras.getStringArrayList("list");
        rate = extras.getStringArrayList("rate");
        for(String str : data)  {
            Log.d("data", str);

        }
        for(String str1 : rate) {
            Log.d("data", str1);

        }

data and rate are two 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));

How to set the two array list in listview ? I can set only one arraylist ?

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

setting the list adapter

        setListAdapter(orderAdapter);

        return ;
    }

Custum listAdapter

         private class OrderAdapter extends BaseAdapter {
        String[] items;

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

Returning the views

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

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

            View view = convertView;

Inflate

            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;
        }
    }

}

Answer 1

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);

Apply thirdList to your Adapter.

Answer 2

Change your constructor to accept two ArrayLists and store them within the Adapter:

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);
    }

And use it like this:

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

Also you should watch this Android lecture on adapters and ListViews to speed up getView().
