如何下载多个firebase Storage Android文件？

dependencies {
    // 其他依赖项...
    implementation 'com.google.firebase:firebase-storage:20.0.0'
}

import com.google.firebase.FirebaseApp;
import com.google.firebase.FirebaseOptions;
import com.google.firebase.storage.FirebaseStorage;
import com.google.firebase.storage.StorageReference;

public class MyApp extends Application {

    @Override
    public void onCreate() {
        super.onCreate();

        // 初始化Firebase应用
        FirebaseApp.initializeApp(this, FirebaseOptions.fromResource(this));

        // 获取Firebase Storage引用
        FirebaseStorage storage = FirebaseStorage.getInstance();
        StorageReference storageRef = storage.getReference();
    }
}

storageRef.listAll().addOnSuccessListener(new OnSuccessListener<ListResult>() {
    @Override
    public void onSuccess(ListResult listResult) {
        for (StorageReference item : listResult.getItems()) {
            item.getFile(localFile)
                .addOnSuccessListener(new OnSuccessListener<FileDownloadTask.TaskSnapshot>() {
                    @Override
                    public void onSuccess(FileDownloadTask.TaskSnapshot taskSnapshot) {
                        // 下载成功
                    }
                })
                .addOnFailureListener(new OnFailureListener() {
                    @Override
                    public void onFailure(@NonNull Exception exception) {
                        // 下载失败
                    }
                });
        }
    }
});
