如何将房间DB中的数据对象传递给WorkManager类

// 步骤1：定义实体类和DAO接口
@Entity
public class RoomData {
    @PrimaryKey
    public int id;
    public String data;
    // 其他属性...
}

@Dao
public interface RoomDataDao {
    @Query("SELECT * FROM RoomData")
    List<RoomData> getAllData();
    // 其他查询方法...
}

// 步骤2：创建自定义Worker
public class MyWorker extends Worker {
    public MyWorker(@NonNull Context context, @NonNull WorkerParameters workerParams) {
        super(context, workerParams);
    }

    @NonNull
    @Override
    public Result doWork() {
        // 获取房间DB的实例
        AppDatabase db = Room.databaseBuilder(getApplicationContext(), AppDatabase.class, "database-name").build();
        // 获取DAO接口
        RoomDataDao dao = db.roomDataDao();
        // 查询需要传递的数据对象
        List<RoomData> dataList = dao.getAllData();
        
        // 执行后台任务，传递数据对象给其他组件或进行其他操作
        
        return Result.success();
    }
}

// 步骤3：调度执行自定义Worker
public class MainActivity extends AppCompatActivity {
    private WorkManager workManager;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        
        workManager = WorkManager.getInstance(this);
        
        // 创建约束条件
        Constraints constraints = new Constraints.Builder()
                .setRequiredNetworkType(NetworkType.CONNECTED)
                .setRequiresCharging(true)
                .build();
        
        // 创建OneTimeWorkRequest，并设置约束条件
        OneTimeWorkRequest workRequest = new OneTimeWorkRequest.Builder(MyWorker.class)
                .setConstraints(constraints)
                .build();
        
        // 调度执行Worker
        workManager.enqueue(workRequest);
    }
}
