如何从回收器视图onclick android studio firestore获取数据

// 步骤2：在布局文件中创建一个回收器视图
<androidx.recyclerview.widget.RecyclerView
    android:id="@+id/recyclerView"
    android:layout_width="match_parent"
    android:layout_height="match_parent" />

// 步骤3：在活动或片段中初始化Firestore数据库的实例和集合引用
private FirebaseFirestore db;
private CollectionReference collectionRef;

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

    db = FirebaseFirestore.getInstance();
    collectionRef = db.collection("your_collection_name");

    // 步骤4：创建适配器类，并将数据绑定到回收器视图中
    RecyclerView recyclerView = findViewById(R.id.recyclerView);
    MyAdapter adapter = new MyAdapter();
    recyclerView.setAdapter(adapter);

    // 步骤5：在适配器类中实现点击事件的监听器
    adapter.setOnItemClickListener(new MyAdapter.OnItemClickListener() {
        @Override
        public void onItemClick(int position) {
            // 步骤6：获取被点击项的位置，并通过位置获取文档ID
            DocumentSnapshot snapshot = adapter.getItem(position);
            String documentId = snapshot.getId();

            // 步骤7：通过文档ID获取文档数据
            collectionRef.document(documentId).get().addOnSuccessListener(new OnSuccessListener<DocumentSnapshot>() {
                @Override
                public void onSuccess(DocumentSnapshot documentSnapshot) {
                    if (documentSnapshot.exists()) {
                        // 获取数据并更新回收器视图的显示
                        YourData data = documentSnapshot.toObject(YourData.class);
                        adapter.updateData(position, data);
                    }
                }
            });
        }
    });
}
