I'm trying to make a quiz app with a RadioGroup, but I want the "next" button to only be enabled/ pressable after a RadioButton is selected. And when pressed, to only show the next card in the CardView. Basically, I don't want the CardView to be scrollable by the user or at best, only scrollable to the next card until radio button is pressed. I know having a next button probably defeats the purpose of having a CardView. A better, cleaner implementation would also be appreciated.

MainAdapter.JAVA

public class MainAdapter extends RecyclerView.Adapter<MainAdapter.ViewHolder> 
 private ArrayList<String> mDataset;

 public MainAdapter(ArrayList<String> mDataset) 
 this.mDataset = mDataset;
 

 @Override
 public MainAdapter.ViewHolder onCreateViewHolder(ViewGroup parent, int viewType) 
 View v = LayoutInflater.from(parent.getContext())
 .inflate(R.layout.cards_adapter, parent, false);
 ViewHolder vh = new ViewHolder(v);
 return vh;
 

 @Override
 public void onBindViewHolder(final ViewHolder holder, final int position) 
 holder.mTitle.setText(mDataset.get(position));


 

 @Override
 public int getItemCount() 
 return mDataset.size();
 

 public class ViewHolder extends RecyclerView.ViewHolder 
 public TextView mTitle;
 public Button nextButton;

 public ViewHolder(View itemView) 
 super(itemView);
 mTitle = itemView.findViewById(R.id.title);
 nextButton = itemView.findViewById(R.id.next_button);
 
 

MainActivity.JAVA

public class MainActivity extends AppCompatActivity {
 private RecyclerView mRecyclerView;
 private RecyclerView.LayoutManager mLayoutManager;
 private RecyclerView.Adapter mAdapter;
 private ArrayList<String> mDataset;

 @Override
 protected void onCreate(Bundle savedInstanceState) 
 super.onCreate(savedInstanceState);
 setContentView(R.layout.activity_main);

 mDataset = new ArrayList<>();
 for (int i = 0; i < 30; i++) 
 mDataset.add("New Title #" + i);
 


 mRecyclerView = findViewById(R.id.recycler_view);
 SnapHelper snapHelper = new PagerSnapHelper();
 snapHelper.attachToRecyclerView(mRecyclerView);

 mRecyclerView.setHasFixedSize(true);
 mLayoutManager = new LinearLayoutManager(this, LinearLayoutManager.HORIZONTAL, false);
 mRecyclerView.setLayoutManager(mLayoutManager);
 mAdapter = new MainAdapter(mDataset);
 mRecyclerView.setAdapter(mAdapter);
