Android中如何解析json字符串 [复制]

Android中的JSON解析

String jsonString = "[{\"name\":\"John\",\"age\":25},{\"name\":\"Mary\",\"age\":30}]";
try {
    JSONArray jsonArray = new JSONArray(jsonString);
    for (int i = 0; i < jsonArray.length(); i++) {
        JSONObject jsonObject = jsonArray.getJSONObject(i);
        String name = jsonObject.getString("name");
        int age = jsonObject.getInt("age");
        // 在这里可以对获取到的数据进行处理
        // 例如，可以将数据显示在界面上或者保存到数据库中
    }
} catch (JSONException e) {
    e.printStackTrace();
}

List> dataList = new ArrayList<>();
try {
    JSONArray jsonArray = new JSONArray(jsonString);
    for (int i = 0; i < jsonArray.length(); i++) {
        JSONObject jsonObject = jsonArray.getJSONObject(i);
        String name = jsonObject.getString("name");
        int age = jsonObject.getInt("age");
        Map data = new HashMap<>();
        data.put("name", name);
        data.put("age", age);
        dataList.add(data);
    }
} catch (JSONException e) {
    e.printStackTrace();
}
SimpleAdapter adapter = new SimpleAdapter(this, dataList, android.R.layout.simple_list_item_2, new String[]{"name", "age"}, new int[]{android.R.id.text1, android.R.id.text2});
ListView listView = findViewById(R.id.list_view);
listView.setAdapter(adapter);
