Android 在从php获取数组时,如何通过JSONArray获取2d数组?_Android - Fatal编程技术网

Android 在从php获取数组时,如何通过JSONArray获取2d数组?

Android 在从php获取数组时,如何通过JSONArray获取2d数组?,android,Android,这是我获取2d阵列的活动 Response.Listener<String> responseListener = new Response.Listener<String>() { @Override public void onResponse(String response) { try { JSONObject jsonResponse = new JSONObjec

这是我获取2d阵列的活动

    Response.Listener<String> responseListener = new Response.Listener<String>() {

        @Override
        public void onResponse(String response) {
            try {
                JSONObject jsonResponse = new JSONObject(response);
                
                //what to do here
                
            } catch (JSONException e) {
                e.printStackTrace();
                AlertDialog.Builder builder = new AlertDialog.Builder(MainActivity.this);
                builder.setMessage("Error")
                        .setNegativeButton("Retry", null)
                        .create()
                        .show();

            }
        }
    };
想让数组像(在android中):-

Arrayquestion=[“问题1”、“问题2”、“问题3”]

Arrayoptiona=[“optiona”、“optiona”、“optiona”]

Arrayoptionb=[“optionb”、“optionb”、“optionb”]

Arrayoptionc=[“optionc”、“optionc”、“optionc”]

Arrayoptiond=[“optiond”、“optiond”、“optiond”]

Arraycorrect=[“optiona”、“optionb”、“optiona”]

成功=[正确]

和助手方法:

private String[] readJsonObject(JSONObject jsonObject) throws JSONException {
        String[] result = new String[3];
        result[0] = jsonObject.getString(Integer.toString(1));
        result[1] = jsonObject.getString(Integer.toString(2));
        result[2] = jsonObject.getString(Integer.toString(3));
        return result;
 }

希望有帮助。

您能删除json图像并用代码块替换它吗?完成,请立即查看响应,仍然会收到错误;(请再核对一下这个问题edited@SumitYadav哪一行有错误?您能发送堆栈跟踪吗?org.json.JSONException:Value{“1”:“question3”,“2”:“question1”,“3”:“question5”}在类型为org.json的问题上,JSONObject不能转换为JSONArray//仅使用一个代码进行检查,它会运行catch(JSONException e)@SumitYadav谢谢,我更新了答案。你能再检查一下吗?老兄,你太棒了
JSONObject jsonResponse = new JSONObject(string);
String[] question = readJsonObject(jsonResponse.getJSONObject("question"));
String[] optiona = readJsonObject(jsonResponse.getJSONObject("optiona"));
String[] optionb = readJsonObject(jsonResponse.getJSONObject("optionb"));
String[] optionc = readJsonObject(jsonResponse.getJSONObject("optionc"));
String[] optiond = readJsonObject(jsonResponse.getJSONObject("optiond"));
String[] correct = readJsonObject(jsonResponse.getJSONObject("correct"));
boolean success = jsonResponse.getBoolean("success");
private String[] readJsonObject(JSONObject jsonObject) throws JSONException {
        String[] result = new String[3];
        result[0] = jsonObject.getString(Integer.toString(1));
        result[1] = jsonObject.getString(Integer.toString(2));
        result[2] = jsonObject.getString(Integer.toString(3));
        return result;
 }
