解析JSON

通过JSONObject解析

private String parseJSONWithJSONObject(String string) {
    String returnData = "";
    try {
        JSONArray jsonArray = new JSONArray(string);
        for (int i = 0; i < jsonArray.length(); i++) {
            JSONObject jsonCbject = jsonArray.getJSONObject(i);
            String id = jsonCbject.getString("id");
            String name = jsonCbject.getString("name");
            String version = jsonCbject.getString("name");
            returnData += id + name + version;
        }
    } catch (JSONException e) {
        e.printStackTrace();
    }
    return returnData;
}

通过GSON解析

//新建APP类
public class APP {
    private int id;
    private String name;
    private String version;

    public int getId() {
        return id;
    }

    public void setId(int id) {
        this.id = id;
    }

    public String getVersion() {
        return version;
    }

    public void setVersion(String version) {
        this.version = version;
    }

    public String getName() {

        return name;
    }

    public void setName(String name) {
        this.name = name;
    }
}



private Object parseJSONWithGSON(String string) {
    Gson gson = new Gson();
    //借助 TypeToken 将期望解析成的数据类型传入到 fromJson()方法中
    List<APP> appList = gson.fromJson(string, new TypeToken<List<APP>>() {}.getType());
    for (APP app : appList) {//foreach循环
        Log.d("MainActivity", "id is " + app.getId());
        Log.d("MainActivity", "name is " + app.getName());
        Log.d("MainActivity", "version is " + app.getVersion());
    }
    return null;
}
