android recyclerview scrollview java

I am currently facing a challenge with a RecyclerView that is nested inside a ScrollView. The RecyclerView does not seem to adapt its height correctly when the content changes dynamically. I am using Android API level 30 and the following layout structure: ```xml <ScrollView android:layout_width="match_parent" android:layout_height="match_parent" android:fillViewport="true"> <LinearLayout android:layout_width="match_parent" android:layout_height="wrap_content" android:orientation="vertical"> <TextView android:layout_width="match_parent" android:layout_height="wrap_content" android:text="Header Text" /> <androidx.recyclerview.widget.RecyclerView android:id="@+id/myRecyclerView" android:layout_width="match_parent" android:layout_height="wrap_content" /> </LinearLayout> </ScrollView> ``` I have set the RecyclerView's height to `wrap_content`, but it seems to only display the first few items and does not expand to show all entries. I tried using `setHasFixedSize(false)` on the RecyclerView, but that did not solve the issue. Additionally, I have implemented a custom adapter to handle dynamic data, and when the data set changes, I call `notifyDataSetChanged()` on the adapter. However, I am still seeing only partial content: ```java public class MyAdapter extends RecyclerView.Adapter<MyAdapter.MyViewHolder> { private List<String> data; public MyAdapter(List<String> data) { this.data = data; } @Override public MyViewHolder onCreateViewHolder(ViewGroup parent, int viewType) { View view = LayoutInflater.from(parent.getContext()).inflate(R.layout.item_layout, parent, false); return new MyViewHolder(view); } @Override public void onBindViewHolder(MyViewHolder holder, int position) { holder.bind(data.get(position)); } @Override public int getItemCount() { return data.size(); } public void updateData(List<String> newData) { this.data = newData; notifyDataSetChanged(); } static class MyViewHolder extends RecyclerView.ViewHolder { TextView itemText; MyViewHolder(View itemView) { super(itemView); itemText = itemView.findViewById(R.id.item_text); } void bind(String text) { itemText.setText(text); } } } ``` The RecyclerView seems to ignore the additional items when there's a change in its data. I also verified that my adapter's `getItemCount()` returns the correct number of items. Could this be a problem related to nested scrolling, or am I missing something in the layout configuration? Any insights would be greatly appreciated!
