The problem is you are storing answers in answ1 array for that time four empty strings adding in ques1 array so you are getting your next question after four times pressing the button....

For that maintain two indexes one for questions and other for answers..

Make Your Array :

ArrayList<String> Question = new ArrayList<String>();
ArrayList<String> Answer = new ArrayList<String>();

Add your value :

Question.add(json_data.getString("QUESTION_TAG").toString());
Answer.add(json_data.getString("ANSWER_TAG").toString());

check List Length and you have to update index in button click.

Button Click Event :

Question.get(index).toString();
Answer.get(index).toString();

Here you can use your data and update index each time after click and if your answer id true.

Note: your index should be maintain otherwise it will throws indexoutofrangeexception Exception.

Hope you can manage according to this.
