I’m working on an Android app and I want to implement a RecyclerView where the item layout changes when it is scrolled to the center horizontally. I’ve included an image below to show what I’m aiming for:
What I Want to Achieve:
When an item in the RecyclerView is scrolled to the center, I want it to change its layout to make it look more prominent (e.g., larger size, different background, etc.).
What I’ve Tried:
-
I have implemented a basic RecyclerView with a horizontal LinearLayoutManager.
-
I have searched for tutorials, but I could only find examples of standard RecyclerView
implementations.My Code So Far:
Here is the basic setup of my RecyclerView:
RecyclerView recyclerView = findViewById(R.id.recyclerView);
recyclerView.setLayoutManager(new LinearLayoutManager(this, LinearLayoutManager.HORIZONTAL, false));
MyAdapter adapter = new MyAdapter(myData);
recyclerView.setAdapter(adapter);
my adapter:
public class MyAdapter extends RecyclerView.Adapter<MyAdapter.ViewHolder> {
private List<MyData> mData;
public MyAdapter(List<MyData> data) {
this.mData = data;
}
@Override
public ViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
View view = LayoutInflater.from(parent.getContext()).inflate(R.layout.item_layout, parent, false);
return new ViewHolder(view);
}
@Override
public void onBindViewHolder(ViewHolder holder, int position) {
// Bind data to the item
}
@Override
public int getItemCount() {
return mData.size();
}
public class ViewHolder extends RecyclerView.ViewHolder {
public ViewHolder(View itemView) {
super(itemView);
}
}
}
How can I detect when an item is centered and change its layout accordingly? Are there specific methods or listeners in RecyclerView that I can use to achieve this effect?
Any guidance or code examples would be greatly appreciated.
