如何在ROOM Database中删除一行后才显示Toast？

@Entity(tableName = "your_table_name")
public class YourEntity {
    @PrimaryKey
    @NonNull
    private String id;

    // 其他字段和构造函数、Getter/Setter方法等
}

@Dao
public interface YourDao {
    @Delete
    void delete(YourEntity entity);
}

@Database(entities = {YourEntity.class}, version = 1)
public abstract class YourDatabase extends RoomDatabase {
    public abstract YourDao yourDao();

    // 单例模式获取数据库实例的方法
    private static YourDatabase instance;

    public static synchronized YourDatabase getInstance(Context context) {
        if (instance == null) {
            instance = Room.databaseBuilder(context.getApplicationContext(),
                    YourDatabase.class, "your_database_name")
                    .build();
        }
        return instance;
    }
}

// 获取数据库实例
YourDatabase database = YourDatabase.getInstance(this);

// 创建一个新的线程来执行数据库操作
new Thread(new Runnable() {
    @Override
    public void run() {
        // 删除操作
        YourEntity entity = new YourEntity();
        // 设置要删除的行的属性
        // ...

        database.yourDao().delete(entity);

        // 在UI线程中显示Toast
        runOnUiThread(new Runnable() {
            @Override
            public void run() {
                Toast.makeText(YourActivity.this, "删除成功", Toast.LENGTH_SHORT).show();
            }
        });
    }
}).start();
