单击RecyclerView项目时，将显示一个新活动，其中包含有关该项目的信息

// 在RecyclerView的适配器中设置点击事件监听器
holder.itemView.setOnClickListener(new View.OnClickListener() {
    @Override
    public void onClick(View v) {
        // 获取被点击项目的信息
        String title = itemList.get(position).getTitle();
        String description = itemList.get(position).getDescription();
        int imageRes = itemList.get(position).getImageRes();

        // 创建Intent对象，启动ProjectDetailActivity
        Intent intent = new Intent(context, ProjectDetailActivity.class);
        intent.putExtra("title", title);
        intent.putExtra("description", description);
        intent.putExtra("imageRes", imageRes);
        context.startActivity(intent);
    }
});

// 在ProjectDetailActivity中获取传递的项目信息并显示
Intent intent = getIntent();
String title = intent.getStringExtra("title");
String description = intent.getStringExtra("description");
int imageRes = intent.getIntExtra("imageRes", 0);

// 显示项目信息
TextView titleTextView = findViewById(R.id.titleTextView);
TextView descriptionTextView = findViewById(R.id.descriptionTextView);
ImageView imageView = findViewById(R.id.imageView);

titleTextView.setText(title);
descriptionTextView.setText(description);
imageView.setImageResource(imageRes);
