使用扩展片段中的意图从recyclerview中创建详细数据

// 在RecyclerView的Adapter中设置点击事件
public class MyAdapter extends RecyclerView.Adapter<MyAdapter.ViewHolder> {
    private List<Item> items;

    public MyAdapter(List<Item> items) {
        this.items = items;
    }

    @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) {
        Item item = items.get(position);
        holder.textView.setText(item.getTitle());

        // 设置点击事件
        holder.itemView.setOnClickListener(v -> {
            Context context = v.getContext();
            Intent intent = new Intent(context, DetailActivity.class);
            intent.putExtra("item_id", item.getId());
            context.startActivity(intent);
        });
    }

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

    public static class ViewHolder extends RecyclerView.ViewHolder {
        public TextView textView;

        public ViewHolder(View view) {
            super(view);
            textView = view.findViewById(R.id.textView);
        }
    }
}

// 在DetailActivity中获取传递的数据
public class DetailActivity extends AppCompatActivity {
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_detail);

        Intent intent = getIntent();
        if (intent != null) {
            int itemId = intent.getIntExtra("item_id", -1);
            // 根据itemId获取详细数据并显示
        }
    }
}

<activity android:name=".DetailActivity" />
