要在RecyclerView的EditText中保留焦点并继续输入，你可以尝试以下解决方法：

1. 在RecyclerView的Adapter中，为每个EditText设置一个TextWatcher监听器，以便在用户输入时更新数据集。例如：

public class MyAdapter extends RecyclerView.Adapter {
    private List mData;

    public MyAdapter(List data) {
        mData = data;
    }

    @NonNull
    @Override
    public ViewHolder onCreateViewHolder(@NonNull 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(@NonNull ViewHolder holder, int position) {
        holder.mEditText.setText(mData.get(position));
        holder.mEditText.addTextChangedListener(new TextWatcher() {
            @Override
            public void beforeTextChanged(CharSequence s, int start, int count, int after) {

            }

            @Override
            public void onTextChanged(CharSequence s, int start, int before, int count) {
                mData.set(holder.getAdapterPosition(), s.toString());
            }

            @Override
            public void afterTextChanged(Editable s) {

            }
        });
    }

    @Override
    public int getItemCount() {
        return mData.size();
    }

    public static class ViewHolder extends RecyclerView.ViewHolder {
        public EditText mEditText;

        public ViewHolder(@NonNull View itemView) {
            super(itemView);
            mEditText = itemView.findViewById(R.id.editText);
        }
    }
}

2. 在Activity或Fragment中，使用LinearLayoutManager来管理RecyclerView，并在适当的时候保存和恢复焦点。例如：

public class MainActivity extends AppCompatActivity {
    private RecyclerView mRecyclerView;
    private MyAdapter mAdapter;
    private LinearLayoutManager mLayoutManager;
    private int mFocusedItemPosition;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        mRecyclerView = findViewById(R.id.recyclerView);
        mLayoutManager = new LinearLayoutManager(this);
        mRecyclerView.setLayoutManager(mLayoutManager);

        List data = new ArrayList<>();
        // 添加一些初始数据
        for (int i = 0; i < 10; i++) {
            data.add("");
        }

        mAdapter = new MyAdapter(data);
        mRecyclerView.setAdapter(mAdapter);
    }

    @Override
    protected void onPause() {
        super.onPause();
        // 保存焦点的位置
        mFocusedItemPosition = mLayoutManager.findFirstVisibleItemPosition();
    }

    @Override
    protected void onResume() {
        super.onResume();
        // 恢复焦点的位置
        mLayoutManager.scrollToPosition(mFocusedItemPosition);
    }
}

这样，当你在EditText中输入内容时，RecyclerView会自动更新数据集，并在Activity或Fragment的生命周期方法中保存和恢复焦点位置。
