How To Do The Next Button Action?

I'm facing a problem in Next button while displaying the next question. In my first time set text I'm getting the correct question and matched four option answers. What I needed is

Solution 1:

I assume, you are trying to manage question and its options on next/previous buttons click.

I achieved in my one of app same as you want:

Step1@ take one int count=0 define globally.

Step2@ when activity is called initially first question will be display with options.

setValues(count); // here I am setting question and options to textview inside setValues named method.

Step3@ onClick of NextButton check condition something like below:

if (count == question.size() - 1) {
    finish();
    break;
} 

else {
count++;
setValues(count);
   }

Step4@ onClick of PreviousButton check condition something like below:

if (count <= 0) {
Toast.makeText(OnPurposeUPSQuesAcitivty.this, "First Record",Toast.LENGTH_SHORT).show();
break;
} else {
count--;
setValues(count);
}

Your setValue method something look like below:

publicvoidsetValues(int j) {
txtque.setText(ques1.get(j));            

btn_practice1.setText(answ1.get(j);
btn_practice2.setText(answ1.get(j);
btn_practice3.setText(answ1.get(j);
btn_practice4.setText(answ1.get(j);
}

...........

Last Point@ After review your code, I don't came across that how you are setting values to options.

this

btn_practice1.setText(answ1.get((k*4)+0));

Will you explain above line of code, will update my answer, else you can use my solution as I mention above steps wise.
