Let’s talk about RecyclerView!
This is a very important design element for Android and almost every application should implement it. If you were ever thinking that you need to implement a list of items, like recent transactions, or a grid, like photos on Instagram, then RecyclerView should definitely be your friend. The video below will cover it in details.
To follow along you can download or fork my starter code from Github.
There are twelve steps altogether:
Step 1. Import dependency
Step 2. Replace ListView with RecyclerView.
Step 3. Replace ListView with RecyclerView in the Java file.
Step 4. Update the adapter.
Step 5. Update the ViewHolder.
Step 6. Update the constructor.
Step 7. Override onCreateViewHolder method.
Step 8. Override onBindViewHolder method.
Step 9. Modify getCount() method.
Step 10. Attach the new adapter.
Step 11. Attach LayoutManager.
Step 12. Attach new OnClickListener.
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.
