从类中获取对我的活动的引用，扩展了RoomPersistence

Question

是否有任何方法可以从扩展Roomdatabase 2的类（用@Database注释的类）中获取我的活动上下文？ 我需要此上下文，以便可以在活动和此类之间初始化接口以传递一些操作？

代码：

@Database(entities = {Movie.class}, version = 1, exportSchema = false)
public abstract class MovieDatabase extends RoomDatabase {
private final static String TAG_LOG = MovieDatabase.class.getSimpleName();

public abstract IDatabaseAccessObject dao();

public MovieDatabase() {
    super();
    Log.w(TAG_LOG, "->MovieDatabase constructor is called.");
}

@Override
public void init(@NonNull DatabaseConfiguration configuration) {
    super.init(configuration);
    Log.w(TAG_LOG, "->init is called. This is called every time Room.databaseBuilder(,,) is accessed.");
}

@Override
public void close() {
    super.close();
    Log.w(TAG_LOG, "->close is called.");
}

@NonNull
@Override
public SupportSQLiteOpenHelper getOpenHelper() {
    Log.w(TAG_LOG, "->getOpenHelper is called.");
    return super.getOpenHelper();
}

@Override
public boolean isOpen() {
    Log.w(TAG_LOG, "->isOpen is called.");
    return super.isOpen();
}

@NonNull
@Override
protected SupportSQLiteOpenHelper createOpenHelper(DatabaseConfiguration config) {
    Log.w(TAG_LOG, "->createOpenHelper is called.");
    Log.d(TAG_LOG, "->createOpenHelper->config.name:" + config.name);
    Log.d(TAG_LOG, "->createOpenHelper->config.callbacks:" + config.callbacks);
    Log.d(TAG_LOG, "->createOpenHelper->config.requireMigration:" + config.requireMigration);
    return null;
}

@NonNull
@Override
protected InvalidationTracker createInvalidationTracker() {
    Log.w(TAG_LOG, "->createInvalidationTracker is called.");
    return null;
}

@Override
public void clearAllTables() {
    Log.w(TAG_LOG, "->clearAllTables is called.");
}
}
