如何从Firebase数据库中获取数据并将其填充到ListView中

dependencies {
    // Firebase Realtime Database
    implementation 'com.google.firebase:firebase-database:20.0.0'
}

FirebaseApp.initializeApp(this);

public class MyAdapter extends ArrayAdapter<String> {
    private List<String> data;

    public MyAdapter(Context context, List<String> data) {
        super(context, android.R.layout.simple_list_item_1, data);
        this.data = data;
    }

    @Override
    public View getView(int position, View convertView, ViewGroup parent) {
        if (convertView == null) {
            convertView = LayoutInflater.from(getContext()).inflate(android.R.layout.simple_list_item_1, parent, false);
        }

        TextView textView = convertView.findViewById(android.R.id.text1);
        textView.setText(data.get(position));

        return convertView;
    }
}

public class MainActivity extends AppCompatActivity {
    private DatabaseReference databaseReference;
    private ListView listView;
    private MyAdapter adapter;

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

        listView = findViewById(R.id.listView);
        List<String> data = new ArrayList<>();
        adapter = new MyAdapter(this, data);
        listView.setAdapter(adapter);

        // 获取Firebase数据库的引用
        databaseReference = FirebaseDatabase.getInstance().getReference("your_node_name");

        // 添加值事件监听器
        databaseReference.addValueEventListener(new ValueEventListener() {
            @Override
            public void onDataChange(@NonNull DataSnapshot dataSnapshot) {
                data.clear();

                // 遍历数据快照，获取数据并添加到列表中
                for (DataSnapshot snapshot : dataSnapshot.getChildren()) {
                    String value = snapshot.getValue(String.class);
                    data.add(value);
                }

                // 通知适配器数据已更改
                adapter.notifyDataSetChanged();
            }

            @Override
            public void onCancelled(@NonNull DatabaseError databaseError) {
                // 处理取消事件
            }
        });
    }
}
