How to move from ListView to RecyclerView?

Great work 🙂

In Step 12, it should be view.setOnClickListener rather than holder.parentView.setOnClickListener.

In Step 4, we need to add
private Context context;
private List contacts;

In Step 6, it should be
NewsAdapter(@NonNull Context context, @NonNull List contacts) {
this.context = context;
this.contacts = contacts;

It also makes more sense to make Step 6 right after Step 4 and make Step 5 right before Step 12 and make Steps 10 & 11 come in the end.

Finally, I’d like to thank you so much. Although I didn’t watch the video, but this page helped me a lot. Thanks again and regards.

thanks Vlad! Really helpful.

	<android.support.v7.widget.RecyclerView xmlns:android="http://schemas.android.com/apk/res/android"
	xmlns:tools="http://schemas.android.com/tools"
	android:id="@+id/list"
	android:layout_width="match_parent"
	android:layout_height="match_parent"
	android:divider="@null"
	tools:context="com.spreys.viewholderexample.ListViewActivity" />

	public class ViewHolder extends RecyclerView.ViewHolder {
	private TextView nameTextView;
	private TextView mobileTextView;
	private TextView landlineTextView;

	public ViewHolder(@NonNull View view) {
	super(view);
	this.nameTextView = (TextView)view
	.findViewById(R.id.name_text_view);
	this.mobileTextView = (TextView)view
	.findViewById(R.id.mobile_text_view);
	this.landlineTextView = (TextView)view
	.findViewById(R.id.landline_text_view);
	}
	}

	@Override
	public ViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
	return new ViewHolder(
	LayoutInflater
	.from(context)
	.inflate(R.layout.contact_item, parent, false)
	);
	}

	@Override
	public void onBindViewHolder(ViewHolder holder, int position) {
	Contact contact = contacts.get(position);

	holder.nameTextView.setText(contact.getName());
	holder.mobileTextView.setText(contact.getMobile());
	holder.landlineTextView.setText(contact.getLandline());
	}

	holder.parentView.setOnClickListener(new View.OnClickListener() {
	@Override
	public void onClick(View view) {
	Intent intent = new Intent(context, DetailsActivity.class);
	intent.putExtra(DetailsActivity.EXTRA_CONTACT, contact);
	context.startActivity(intent);
	}
	});

Let’s talk about RecyclerView!
