有什么建议吗?什么不起作用?你看到的数字是不是有错误的值,或者根本没有显示数字?@Eran我什么也看不到。没有数字出现。当我出现时。setNumber2;数字出现。但是使用.setNumber2++numMessages;没有出现。如果你是passin,则haps numMessages不包含你认为它的内容g 0,这可能是未显示任何内容的原因。您从全局变量获取值,但我不确定应用程序未运行时该变量会发生什么情况。也许您应该将该数字存储在共享首选项中,然后从共享首选项中加载它。我在通知负载中接收通知编号作为标记。我将其解析为整数,但不包含number不会出现在设备中。我也尝试过静态设置数字,但在这种情况下,它会按预期工作。
