// Example code to migrate from ListView to RecyclerView // Step 1: Add RecyclerView to your layout XML <androidx.recyclerview.widget.RecyclerView android:id="@+id/recycler_view" android:layout_width="match_parent" android:layout_height="match_parent"/> // Step 2: Create a ViewHolder class public class MyViewHolder extends RecyclerView.ViewHolder { public TextView textView; public MyViewHolder(View view) { super(view); textView = view.findViewById(R.id.textView); } } // Step 3: Create an Adapter class public class MyAdapter extends RecyclerView.Adapter { private List dataList; public MyAdapter(List dataList) { this.dataList = dataList; } @Override public MyViewHolder onCreateViewHolder(ViewGroup parent, int viewType) { View itemView = LayoutInflater.from(parent.getContext()) .inflate(R.layout.list_item, parent, false); return new MyViewHolder(itemView); } @Override public void onBindViewHolder(MyViewHolder holder, int position) { holder.textView.setText(dataList.get(position)); } @Override public int getItemCount() { return dataList.size(); } } // Step 4: Set up RecyclerView in your Activity/Fragment RecyclerView recyclerView = findViewById(R.id.recycler_view); MyAdapter adapter = new MyAdapter(myDataList); recyclerView.setLayoutManager(new LinearLayoutManager(this)); recyclerView.setAdapter(adapter);
