Android-SimpleAdapter使用方法

        // [1] 找到控件
        ListView lv = (ListView) findViewById(R.id.lv);

        // [1.1] 准备listview要显示的数据
        List<Map<String, String>> data = new ArrayList<>();

        Map<String, String> map1 = new HashMap<>();
        map1.put("name", "张飞");
        map1.put("phone", "13888888888");

        Map<String, String> map2 = new HashMap<>();
        map2.put("name", "赵云");
        map2.put("phone", "110");

        Map<String, String> map3 = new HashMap<>();
        map3.put("name", "貂蝉");
        map3.put("phone", "13888882223");

        map4.put("name", "诸葛亮");
        map4.put("phone", "13888881234");

        // [1.2] 把map假如到集合中
        data.add(map1);
        data.add(map2);
        data.add(map3);
        data.add(map4);

        // [2] 设置数据适配器

        // form map集合的键
        SimpleAdapter adapter = new SimpleAdapter(getApplicationContext(), data, R.layout.item,
