Assuming that you have the layout in place for your quiz:

In your activity you can do something like:

Button nextButton=(Button) findViewById(R.id.nextbutton);
        nextButton.setOnClickListener(new OnClickListener() {

            @Override
            public void onClick(View v) {
                question.setText(questions.get(questionNumber));
answersList = new AnswersListAdapter(
                getBaseContext(), splitAnswers[questionNumber], -1 , false);
answers.setAdapter(answersList);

            }
        });

AnswersListAdapter.java

import android.content.Context;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.widget.BaseAdapter;
import android.widget.ImageView;
import android.widget.RelativeLayout;
import android.widget.TextView;

public class AnswersListAdapter extends BaseAdapter {

    private Context context;
    private String [] splitAnswers;
    public AnswersListAdapter(Context context,String [] splitAnswers){
        super();
        this.context=context;
        this.splitAnswers=splitAnswers;
    }

    @Override
    public int getCount() {
        return splitAnswers.length;
    }

    @Override
    public Object getItem(int arg0) {
        return splitAnswers[arg0];
    }

    @Override
    public long getItemId(int arg0) {
        return splitAnswers[arg0].hashCode();
    }

    @Override
    public View getView(int position, View arg1, ViewGroup arg2) {
        LayoutInflater inflater = LayoutInflater.from(context);
        RelativeLayout root = (RelativeLayout) inflater.inflate(R.layout.answers_item, null,false);

        TextView label =(TextView) root.findViewById(R.id.label);
        ImageView options=(ImageView) root.findViewById(R.id.options);


                label.setText(splitAnswers[position]);
        return root;
    }

}

answers_item.xml

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:padding="2dp" >
    <TextView
        android:id="@+id/label"
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        android:paddingBottom="3dp"
        android:paddingLeft="50dp"
        android:paddingTop="3dp"
        android:text="@+id/label"
        android:textColor="#FFFFFF" >
    </TextView>
    <ImageView
        android:id="@+id/options"
        android:layout_width="30dp"
        android:layout_height="30dp"
        android:layout_alignLeft="@id/label"
        android:layout_alignTop="@id/label"
        android:background="@drawable/a" >
    </ImageView>
</RelativeLayout>

You might have to do some customization depening on where exactly your data is coming in from and also few other factors. Hope it helps.
