Android 递归JSON解析器

我需要通过递归解析这个json

{
    "code": "200",
    "data": [
        {
            "id": "2",

    ]
}

试试看
{
JSONObject json=新的JSONObject（“响应”）；
JSONArray dataArray=json.getJSONArray（“数据”）；
对于（int i=0；i我还没有尝试过，但逻辑上应该是这样的：

public void solve(JSONArray dataArray){
    try {
        for(int i = 0; i < dataArray.length(); i++) {
            JSONObject dataObj = dataArray.getJSONObject(i);
            System.out.println(dataObj.getString("id"));
            System.out.println(dataObj.getString("name"));
            System.out.println(dataObj.getString("parent"));
            JSONArray childArray = dataObj.getJSONArray("children");
            solve(childArray);
        }
    } catch(Exception e) {
        e.printStackTrace();
    }
}

public void solve（JSONArray数据数组）{
试一试{
对于（int i=0；i
你到底想要什么？我需要解析这个，并想设置一个微调器..选择BE/ME/Btech后，我需要获取子数据[第二个微调器中的计算机科学]再次选择computer science后，需要在单独的spinnerAll中获取子数据，如1st yr或2nd yr，JSON解析器将通过树递归解析。只需根据所选键浏览java.util.Map即可。
public void solve(JSONArray dataArray){
    try {
        for(int i = 0; i < dataArray.length(); i++) {
            JSONObject dataObj = dataArray.getJSONObject(i);
            System.out.println(dataObj.getString("id"));
            System.out.println(dataObj.getString("name"));
            System.out.println(dataObj.getString("parent"));
            JSONArray childArray = dataObj.getJSONArray("children");
            solve(childArray);
        }
    } catch(Exception e) {
        e.printStackTrace();
    }
}
