How to stop the running timer with EditText?

I'm trying to create an app that shows some questions and EditText fields in front of the each of the question for an answer with CountDownTimer, the problem I have is I'm trying to stop the running CountDownTimer on the last entered answer and save those seconds next to user's name but not sure how? I know questionTimer.cancel() would stop the timer but it has to be done on the last entered answer in last EditText.
This is the MainActivity.java file:
public class MainActivity extends AppCompatActivity {
CountDownTimer questionTimer;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
btnStart = (Button) findViewById(R.id.start);
btnStart.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
setQuestions();
timer();
}
});
}//End of create()
public void timer() {
questionTimer = new CountDownTimer(30000, 1000) {
public void onTick(long millisUntilFinished) {
timer = (TextView) findViewById(R.id.timer);
timer.setText("Seconds Remaining: " + millisUntilFinished / 1000);
}
public void onFinish() {
timer.setText("Done!");
}
}.start();
}
public void setQuestions() {
ArrayList<Questions> qArrList = new ArrayList<>();
for (int i = 0; i < 5; i++) {
ques = new Questions();
ques.setQuestion("");
qArrList.add(ques);
}
adapter = new AdapterListView(getBaseContext(), R.layout.item_listview, qArrList);
questListView.setAdapter(adapter);
}
}//End of Class
This is the AdapterListView.java file:
public class AdapterListView extends ArrayAdapter<Questions> {
Context mContext;
LayoutInflater inflater;
private ArrayList<Questions> questionsArrayList;
private Questions quesObject;
private ArrayList<String> quesList = new ArrayList<String>();
private int a, b, ab, c, d, cd, e, f, ef, g, h, gh, i, j, ij;
private ArrayList<Integer> answersList = new ArrayList<Integer>();
public AdapterListView(Context context, int resource, ArrayList<Questions> questionsArrayList) {
super(context, resource);
this.mContext = context;
this.setQuestionsArrayList(questionsArrayList);
this.inflater = (LayoutInflater) context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
}
#Override
public View getView(final int position, View convertView, ViewGroup parent) {
final ViewHolder holder;
if (convertView == null) {
convertView = inflater.inflate(R.layout.item_listview, null);
holder = new ViewHolder();
holder.questionTextView = convertView.findViewById(R.id.question);
holder.editText = convertView.findViewById(R.id.ans_edit_text);
holder.imgTrue = convertView.findViewById(R.id.ans_true);
holder.imgFalse = convertView.findViewById(R.id.ans_false);
convertView.setTag(holder);
} else {
holder = (ViewHolder) convertView.getTag();
}
quesObject = getQuestionsArrayList().get(position);
int count = 0;
if (position == 0) count = 1;
else if (position == 1) count = 2;
else if (position == 2) count = 3;
else if (position == 3) count = 4;
else if (position == 4) count = 5;
Random rand = new Random();
a = (rand.nextInt(15) + 1);

quesList.add(i + " + " + j);
getAnswersList().add(ab);
getAnswersList().add(cd);
getAnswersList().add(ef);
getAnswersList().add(gh);
getAnswersList().add(ij);
holder.questionTextView.setText("Q " + count + ": \t" + quesList.get(position));
holder.editText.addTextChangedListener(new TextWatcher() {
public void afterTextChanged(Editable s) {
if (holder.editText.getText().toString().trim().length() > 0) {
int inputNum = Integer.parseInt(String.valueOf(holder.editText.getText().toString().trim()));
if (getAnswersList().get(position) != inputNum) {
holder.imgFalse.setVisibility(View.VISIBLE);
holder.imgTrue.setVisibility(View.GONE);
} else {
holder.imgTrue.setVisibility(View.VISIBLE);
holder.imgFalse.setVisibility(View.GONE);
}
}
}
public void beforeTextChanged(CharSequence s, int start, int count, int after) {
}
public void onTextChanged(CharSequence s, int start, int before, int count) {
}
});
return convertView;
}
#Override
public int getCount() {
return getQuestionsArrayList().size();
}
static class ViewHolder {
TextView questionTextView;
EditText editText;
ImageView imgTrue, imgFalse;
}
}

I have manged to sort this out by setting an int variable against Position and calling this in MainActivity class inside the running Timer. Please see the code below.
public class MainActivity extends AppCompatActivity {
CountDownTimer questionTimer;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
btnStart = (Button) findViewById(R.id.start);
btnStart.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
setQuestions();
timer();
}
});
}//End of create()
public void timer() {
questionTimer = new CountDownTimer(30000, 1000) {
public void onTick(long millisUntilFinished) {
timer = (TextView) findViewById(R.id.timer);
timer.setText("Seconds Remaining: " + millisUntilFinished / 1000);
if (adapter.getEndQuiz() == 5) {
questionTimer.cancel();
}
}
public void onFinish() {
timer.setText("Done!");
}
}.start();
}
public void setQuestions() {
ArrayList<Questions> qArrList = new ArrayList<>();
for (int i = 0; i < 5; i++) {
ques = new Questions();
ques.setQuestion("");
qArrList.add(ques);
}
adapter = new AdapterListView(getBaseContext(), R.layout.item_listview, qArrList);
questListView.setAdapter(adapter);
}

Unable to calculate proper value from each row in ListView

// i have two button for increasing and decreasing the quantity, after increasing or decreasing the value i want to calculate price from each row but it is not giving correct value.Also the quantity getting changed while scrolling .Mostly the above said problem occurs whenever the size of listview is more than screen size.

Never update an item view in a list from the event handler (controller).
It looks like you are correctly updating the model (prodetailarray), but in an onClick or any event handler, all you want to do is update the model and then call notifyDataSetChanged(). This will inform your list view that the model has changed, and the list view will regenerate item views based on the new model data.
If that's not sufficient to solve your problem, you'll need to post your entire adapter code so we can identify the problem.

Your application is sticking when you're scrolling down because you're doing all of that processing upon every move when you scroll. Every row is running through the statements of your getView method every single time it's brought back to the screen, phones don't have enough processing power for all of that. You need to separate all of that into a different class, and then load it into the adapter in a smaller data set so that all it has to do is display it. Basically, you're doing processing in the UI(Main) thread, which is bad.
Given how you also have nested listViews, changing to an expandedListView would also be a lot easier for you in the grand scheme of things, may do the job better. Here's a tutorial for it: https://www.youtube.com/watch?v=BkazaAeeW1Q

Item deleting from listview affecting asynctask

I am making a multi-video downloader. I have created a listview and for each item in the listview an asynctask is called which downloads the file in the background. Everything works perfect. But, if i want to delete an item from the listview for example from position 2, the item at position 3 (both are currently running) comes on position 2 and the asynctask attached previously to position 2 continues running and it shows the progress of asynctask that was previously attached to the position 2. How can I move the asynctask of position 3 to position 2.
Here is my Adapter Class from where I am calling the asynctask class:
public class DownloadInfoArrayAdapter extends ArrayAdapter<DownloadInfo> {
public static TextView progpercent;
// Simple class to make it so that we don't have to call findViewById frequently
// private static final String TAG = FileDownloadTask.class.getSimpleName();

you should override the remove method of your adapter in order to cancel properly the asyncTask associated to your item.
