I'm creating an app for Quiz. I populated the listview with radio buttons but on
clicking on any radio button same button in next fourth rows are selecting automatically.
Here is my code MainActivity.java
public class MainActivity extends AppCompatActivity {
String ques_pdf;
PDFView pdfView;
String url = "api.abc.com"
private List<VideoListDataItem> dataFeed= new ArrayList<VideoListDataItem>();
ListView listView;
String test_id,marked_answer;
String q_no;
@Nullable
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
pdfView = (PDFView)findViewById(R.id.question_pdf);
final ArrayAdapter<VideoListDataItem> adapter = new MainActivity.Adapter();
listView = findViewById(R.id.listview_answers);
RequestQueue queue = Volley.newRequestQueue(getApplicationContext());
JsonObjectRequest jsonObjectRequest = new JsonObjectRequest(Request.Method.GET,
url, null,
new Response.Listener<JSONObject>() {
@Override
public void onResponse(JSONObject response) {
try {
JSONArray temp = response.getJSONArray("mock_test_pt");
for (int i = 0; i < temp.length(); i++) {
JSONObject buffer = temp.getJSONObject(i);
String marks_correct_ans= buffer.getString("marks_correct_ans");
String negative_mark= buffer.getString("negative_mark");
String duration = buffer.getString("duration");
ques_pdf = buffer.getString("ques_pdf");
String total_question = buffer.getString("total_question");
test_id = buffer.getString("id");
Log.i(" Test id",buffer.getString("id"));
int total_questions = Integer.parseInt(total_question);
for (int j=1;j<=total_questions;j++) {
dataFeed.add(new VideoListDataItem("" + j, "", "", "", "", ""));
adapter.notifyDataSetChanged();
}
new RetrievePDF().execute(ques_pdf);
Log.i("ques_pdf",ques_pdf);
}
} catch (JSONException e) {
e.printStackTrace();
}
}
}, new Response.ErrorListener() {
@Override
public void onErrorResponse(VolleyError error) {
}
});
jsonObjectRequest.setRetryPolicy(new DefaultRetryPolicy(10000, DefaultRetryPolicy.DEFAULT_MAX_RETRIES, DefaultRetryPolicy.DEFAULT_BACKOFF_MULT));
queue.add(jsonObjectRequest);
Log.i("Test paper","After loading pdf");
JsonObjectRequest jsonObjectRequest2 = new JsonObjectRequest(Request.Method.GET,
url, null,
new Response.Listener<JSONObject>() {
@Override
public void onResponse(JSONObject response) {
try {
Log.i("Answer", "" + response.toString());
JSONArray temp = response.getJSONArray("subject_wise_test_ans");
for (int i = 0; i < temp.length(); i++) {
JSONObject buffer = temp.getJSONObject(i);
JSONObject answer = buffer.getJSONObject("answer");
String id= buffer.getString("id");
String test_id1= buffer.getString("test_id");
Log.i("Test Id in answer",test_id1);
String subject_name = buffer.getString("subject_name");
String marks_pluse = buffer.getString("marks_pluse");
String marks_minus = buffer.getString("marks_minus");

q_no = buffer.getString("question_no");
String temp_string;
temp_string=test_id;
Log.i("Answer API",answer.toString());
if (test_id1.equals(test_id) ) {
// Toast.makeText(getApplicationContext(), "Matched!!!", Toast.LENGTH_SHORT).show();
break;
}
}
Log.i("QID",test_id);
} catch (JSONException e) {

Everything is working fine in this code except radio buttons. Radio button of different rows are getting selected automatically
