AlertDialog中使用ListView绑定数据

在实际工作过程中，单单使用AlertDialog的单选功能不一定能满足我们的需求，需要绑定数据到 listview 

 

1. 自定义Layout

LayoutInflater factory = LayoutInflater.from(DialogActivity.this);
final View view = factory.inflate(R.layout.linerlayout, null);

2,构造数据

List<Map<String, String>> nameList = new ArrayList<Map<String, String>>();//建立一个数组存储listview上显示的数据
for (int m = 0; m < 15; m++) {//initData为一个list类型的数据源
    Map<String, String> nameMap = new HashMap<String, String>();
    nameMap.put("name", "name"+m);
    nameMap.put("id", m+"");
    nameList.add(nameMap);
}

3ListView数据绑定

listView= (ListView) view.findViewById(R.id.lv_list);

listView.setChoiceMode(ListView.CHOICE_MODE_SINGLE);

SimpleAdapter adapter = new SimpleAdapter(DialogActivity.this,
        nameList, R.layout.item,
        new String[] { "name","id" },
        new int[] { R.id.tv1 ,R.id.tv2});
listView.setAdapter(adapter);

4.AlertDialog 绑定

  final AlertDialog dialog = new AlertDialog.Builder(this)
                .setTitle("选择姓名").setView(view)//在这里把写好的这个listview的布局加载dialog中
                .setNegativeButton("取消", new DialogInterface.OnClickListener() {

                    @Override
                    public void onClick(DialogInterface dialog, int which) {
// TODO Auto-generated method stub
                        dialog.cancel();
                    }
                }).create();
        dialog.setCanceledOnTouchOutside(false);//使除了dialog以外的地方不能被点击
        dialog.show();

5. LIstview 点击事件

 listView.setOnItemClickListener(new AdapterView.OnItemClickListener() {//响应listview中的item的点击事件

            @Override
            public void onItemClick(AdapterView<?> arg0, View arg1, int arg2,
                                    long arg3) {
                Log.d("TAG","ok");
// TODO Auto-generated method stub
                TextView btn = (TextView) arg1 .findViewById(R.id.tv2);//取得每条item中的textview控件
             //   et_name.setText(tv.getText().toString());


                Log.d("TAG",btn.getText().toString());
               // dialog.cancel();
            }
        });
