关于该项目：

为什么我想做：

我想单击批准按钮将通知/消息保存到批准的通知/消息数据库中。但我注意到，当我点击 Aprrove 按钮时，它被插入，当点击 Rejected 按钮时，它也被插入到 Rejected 表中。因此，我检查是否不在拒绝表中，然后将其插入到批准表中。那时一切都很好，但是当我做同样的事情时（从批准中删除通知并插入拒绝），然后我得到了 StackOverFlow 错误。

这是生成错误的代码：

public RejectedNotifications(Context context) {
        super(context, TABLE_NAME_REJECTED_NOTIFICATION, null, DATABASE_VERSION);
        ***approved = new ApprovedNotifications(context);***
    }

表 Approved 的另一个数据库处理程序类似于关于代码：

public ApprovedNotifications(Context context) {
        super(context, TABLE_NAME_APPROVED_NOTIFICATION, null, DATABASE_VERSION);
        rejected = new RejectedNotifications(context);
    }

您已经在代码中创建了一个无限循环。每次创建实例时ApprovedNoficiations，它都会创建一个RejectedNotifications实例，然后再创建另一个ApprovedNotifications实例，依此类推......

这两个类之间的关系是循环的。如果您希望两个实例相互引用，您可能需要先创建一个，然后将其作为参数传递给第二个。

你有一个非常清晰的无限递归。ApprovedNotifications的构造函数创建一个新的RejectedNotifications. RejectedNotifications构造函数创建一个新ApprovedNotifications的，等等。
