Question

这是我获得2d数组的活动

{
  plugins: [
    new HtmlWebpackPlugin({
      template: 'src/index.html'
    })
  ]
}

获得＆＃34;响应＆＃34;的这个值在调用它:(我编辑了这个）在此代码中使用JSONArray

    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();

            }
        }
    };

想要制作像（在android中）的数组： -

Arrayquestion = [＆＃34;问题1＆＃34;＆＃34;问题2＆＃34;＆＃34;问题3＆＃34;]

Arrayoptiona = [＆＃34; optiona＆＃34;＆＃34; optiona＆＃34;＆＃34; optiona＆＃34;]

Arrayoptionb = [＆＃34; optionb＆＃34;＆＃34; optionb＆＃34;＆＃34; optionb＆＃34;]

Arrayoptionc = [＆＃34; OptionC中＆＃34;＆＃34; OptionC中＆＃34;＆＃34; OptionC中＆＃34;]

Arrayoptiond = [＆＃34; optiond＆＃34;＆＃34; optiond＆＃34;＆＃34; optiond＆＃34;]

Arraycorrect = [＆＃34; optiona＆＃34;＆＃34; optionb＆＃34;＆＃34; optiona＆＃34;]

成功= [TRUE]

Answer 1

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");

辅助方法：

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;
 }

希望它有所帮助。
