ListView一行显示两个Item并实现单选功能

最终效果如上图所示意

核心代码只要是Adapter里面完成一行显示两个item，并且加入一个回调接口进行返回数据

public class MyAdapter extends BaseAdapter {private List<Payment> mList;private Context mContext;private int sumCount;private ChangeTextView changeTextView;public Handler handler = new Handler() {public void handleMessage(Message msg) {switch (msg.what) {case 1:changeTextView.changeTheText(msg.arg1);break;default:break;}};};public MyAdapter(List<Payment> List, Context context, ChangeTextView changeTextView) {this.mList = List;this.mContext = context;this.changeTextView = changeTextView;}@Overridepublic int getCount() {int count = mList.size();if (count % 2 == 0) {sumCount = count / 2; // 如果是双数直接减半} else {sumCount = (int) Math.floor((double) count / 2) + 1;}return sumCount;}@Overridepublic Object getItem(int position) {return mList.get(position);}@Overridepublic long getItemId(int position) {return position;}static class ViewHolder {PayItem payitem1;PayItem payitem2;}@Overridepublic View getView(int position, View convertView, ViewGroup parent) {ViewHolder holder = null;if (convertView == null) {holder = new ViewHolder();convertView = LayoutInflater.from(mContext).inflate(R.layout.list_pay_item, null);holder.payitem1 = (PayItem) convertView.findViewById(R.id.payItem1);holder.payitem2 = (PayItem) convertView.findViewById(R.id.payItem2);convertView.setTag(holder);} else {holder = (ViewHolder) convertView.getTag();}holder.payitem1.setDescription(mList.get(position * 2).getDescription());holder.payitem1.setDetail(mList.get(position * 2).getDetail());holder.payitem1.setCharge(mList.get(position * 2).getCharge());holder.payitem1.setIsSelected(mList.get(position * 2).getStatus());if (position * 2 + 1 == mList.size()) {holder.payitem2.setVisibility(View.INVISIBLE); // 如果是单数的话，那么最后一个item，右侧内容为空} else {holder.payitem2.setVisibility(View.VISIBLE); // 必须进行设置，负责存在复用holder的时候，会出现右侧的出现留白，跟最后一个一样，这个也是我写这篇文章最想锁的holder.payitem2.setDescription(mList.get(position * 2 + 1).getDescription());holder.payitem2.setDetail(mList.get(position * 2 + 1).getDetail());holder.payitem2.setCharge(mList.get(position * 2 + 1).getCharge());holder.payitem2.setIsSelected(mList.get(position * 2+1).getStatus());}holder.payitem1.setMyItemClickedListener(new MyOnEvenClick(position));holder.payitem2.setMyItemClickedListener(new MyOnOddClick(position));return convertView;}private class MyOnEvenClick implements MyItemClicked {int pos = 0;public MyOnEvenClick(int position) {this.pos = position * 2;}@Overridepublic void myItemClicked() {Message message = new Message();message.what = 1;message.arg1 = pos;handler.sendMessage(message);}}private class MyOnOddClick implements MyItemClicked {int pos = 0;public MyOnOddClick(int position) {this.pos = position * 2 + 1;}@Overridepublic void myItemClicked() {Message message = new Message();message.what = 1;message.arg1 = pos;handler.sendMessage(message);}}// 设置监听interface ChangeTextView {void changeTheText(int position);}}

界面很单薄，可以自行修改
