ListView與RecyclerView列表項編輯模式

ListView和RecyclerView都可以實現列表項的編輯模式，具體操作方法如下：

1. ListView編輯模式：在ListView中實現編輯模式通常需要自定義適配器，并在適配器中添加編輯模式的邏輯。可以通過在列表項中添加編輯按鈕或長按列表項觸發(fā)編輯模式。

// 創(chuàng)建自定義適配器
public class CustomAdapter extends ArrayAdapter<String> {
    private boolean editMode = false;

    public CustomAdapter(Context context, List<String> items) {
        super(context, 0, items);
    }

    @Override
    public View getView(int position, View convertView, ViewGroup parent) {
        View view = convertView;
        if (view == null) {
            view = LayoutInflater.from(getContext()).inflate(R.layout.list_item, parent, false);
        }

        TextView text = view.findViewById(R.id.item_text);
        Button editButton = view.findViewById(R.id.edit_button);

        text.setText(getItem(position));

        if (editMode) {
            editButton.setVisibility(View.VISIBLE);
        } else {
            editButton.setVisibility(View.GONE);
        }

        return view;
    }

    public void setEditMode(boolean editMode) {
        this.editMode = editMode;
        notifyDataSetChanged();
    }
}

2. RecyclerView編輯模式：在RecyclerView中實現編輯模式通常需要自定義RecyclerView.Adapter，并在適配器中添加編輯模式的邏輯?？梢酝ㄟ^在列表項中添加編輯按鈕或長按列表項觸發(fā)編輯模式。

// 創(chuàng)建自定義適配器
public class CustomAdapter extends RecyclerView.Adapter<CustomAdapter.ViewHolder> {
    private List<String> items;
    private boolean editMode = false;

    public CustomAdapter(List<String> items) {
        this.items = items;
    }

    @Override
    public ViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
        View view = LayoutInflater.from(parent.getContext()).inflate(R.layout.list_item, parent, false);
        return new ViewHolder(view);
    }

    @Override
    public void onBindViewHolder(ViewHolder holder, int position) {
        holder.text.setText(items.get(position));

        if (editMode) {
            holder.editButton.setVisibility(View.VISIBLE);
        } else {
            holder.editButton.setVisibility(View.GONE);
        }
    }

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

    public void setEditMode(boolean editMode) {
        this.editMode = editMode;
        notifyDataSetChanged();
    }

    public class ViewHolder extends RecyclerView.ViewHolder {
        TextView text;
        Button editButton;

        public ViewHolder(View itemView) {
            super(itemView);
            text = itemView.findViewById(R.id.item_text);
            editButton = itemView.findViewById(R.id.edit_button);
        }
    }
}

通過以上方法，可以實現在ListView和RecyclerView中切換列表項的編輯模式。
