My question is: how do I access the next question of "questions" when i click next for the next question since "58242", "58245", etc are all dynamic values?

the answer on this post was very helpfull but now i want to now how loop through the questions How to parse a dynamic JSON key in a Nested JSON result

it helped me get the currentdynamic value but does not give me the next question when i click on next

private View.OnClickListener nextListener = new View.OnClickListener() {
        public void onClick(View v) {
            setAnswer();
            try {
                if (quesIndex != searchResult.getJSONObject("questions").length() - 1) {
                    quesIndex++;
                    progress.setProgress(0);
                    progress.setMax(100);
                } else {
                    Intent myIntent = new Intent(TestActivity.this, Assesment.class);
                    myIntent.putExtra("intVariableName", score);
                    startActivity(myIntent);
                }
            } catch (JSONException e) {
                e.printStackTrace();
            }
            try {
                if (quesIndex == searchResult.getJSONObject("questions").length() - 1) {
                    next.setText("Finish");

                    Intent myIntent = new Intent(TestActivity.this, Assesment.class);
                    myIntent.putExtra("intVariableName", score);
                    startActivity(myIntent);
                    // close this activity
                    finish();
                }
            } catch (JSONException e) {
                e.printStackTrace();
            }
            showQuestion(quesIndex, review);
        }
    };

will appreciate the help thanks :)

Not sure what you problem is. Seems like the solution is in the link you gave above.

JSONObject questions = result.getJSONObject("questions");
Iterator keys = questions.keys();

//go through every question
while (keys.hasNext()) {
    String currentDynamicKey = (String)keys.next();
    JSONObject currentQuestion = questions.getJSONObject(currentDynamicKey);
}
