推荐答案

请像这样（联系人列表样本）的列表视图适配器，

Make an list view adapter like this, (Sample for a contact list)

public class ContactListAdapter extends ArrayAdapter<Contact>
{

    private int resource;

    public ContactListAdapter(Context context, int resource, List<Contact> items)
    {
        super(context, resource, items);

        this.resource = resource;
    }

    @Override
    public View getView(int position, View convertView, ViewGroup parent)
    {
        ViewHolder holder = null;
        LinearLayout contactListView;

        if (convertView == null)
        {
            contactListView = new LinearLayout(getContext());
            String inflater = Context.LAYOUT_INFLATER_SERVICE;
            LayoutInflater layoutInflater;
            layoutInflater = (LayoutInflater) getContext().getSystemService(inflater);
            layoutInflater.inflate(resource, contactListView, true);

            holder = new ViewHolder();

            holder.textViewName = (TextView) contactListView.findViewById(R.id.name);
            holder.textViewAddress = (TextView) contactListView.findViewById(R.id.address);

            contactListView.setTag(holder);
        }
        else
        {
            contactListView= (LinearLayout) convertView;

            holder = (ViewHolder) contactListView.getTag();
        }

        Contact item = getItem(position);

        holder.textViewName.setText(item.getName());
        holder.textViewAddress.setText(item.getAddress());

        return contactListView;
    }

    protected static class ViewHolder
    {
        TextView textViewName;
        TextView textViewAddress;
    }
}

设置该适配器将列表视图。通过在XML布局到该适配器的资源ID。它将从XML紧缩的观点，并将其添加到列表视图。

Set this adapter to your listview. Pass in the resource id of your xml layout to this adapter. It would deflate the view from the xml and add it to the listview.

您还可以调整列表视图项目的高度在上面的 getView（）适配器的方法。使用的LayoutParams ofcourse。

You can also adjust the heights of the listview items in the above getView() method of the adapter. Using LayoutParams ofcourse.
