CodePudding user response：

you need to add abutton to confirm action in viewholder

 public class MyViewClass extends RecyclerView.ViewHolder{
    TextView id;
    .
    .
    EditText answer;
    Button getAnswer;
    public MyViewClass(@NonNull View itemView) {
        super(itemView);
        id = itemView.findViewById(R.id.questionid);
        .
        .
        getAnswer=itemView.findViewById(R.id.getAnswer);




    }
}

and in the onBindViewHolder add this

holder.getAnswer.setOnClickListener(new View.OnClickListener() {
    @Override
    public void onClick(View v) {
        answer.add(answer.getText().toString());
    }
});

now the answere list will have a list of answers that get from edit text

CodePudding user response：

use addTextChangedListener to your editText so that you can observe changes and add to your arrayList,

If you want to pass same value to Activity then you can create interface class and write a method which you can implement in Activity or you can use eventBus to pass value.
