Java 应用程序警报导致奇怪的错误，直到我按下后退按钮
我的应用程序中有一个警报，每10分钟通知我一次。它运行良好，但每当警报通知我，我的应用程序名称将显示为一个框在屏幕中部，我不能按下任何东西，直到我按下后退按钮。真奇怪 这是我的代码：Java 应用程序警报导致奇怪的错误，直到我按下后退按钮,java,android,alarm,android-alarms,alarms,Java,Android,Alarm,Android Alarms,Alarms,我的应用程序中有一个警报，每10分钟通知我一次。它运行良好，但每当警报通知我，我的应用程序名称将显示为一个框在屏幕中部，我不能按下任何东西，直到我按下后退按钮。真奇怪 这是我的代码： // Alert Code final AlertDialog alertDialog = new AlertDialog.Builder(this).create(); alertDialog.setTitle("Confirmation"); alertDialog.setMes

您似乎没有重载back语句，因此，当您按下back按钮时，您将返回到后台堆栈。Android文档中有关于这方面的更多信息：
实际上我不明白？你能给我提供密码吗？我怎么做？我们的工作不是帮助你。礼貌会给你带来更多的帮助，而不是对那些给你建议的人大喊大叫。你不会发现有很多人可以编写代码来解决这个问题（尤其是在我们面前没有所有的代码可以处理的情况下）。我的理论是，你的应用程序正在重新启动，你的应用程序中的方框是某种启动屏幕（我假设方框和名称是你创建的某个屏幕）。我之前链接的后台堆栈只是向您显示，通过回击退出应用程序，这就是回击关闭对话框的原因。当MyAlarmService从您的警报接收到意图时，它会做什么？它向我显示“显示对话框”活动，请检查updatea屏幕截图将有助于更好地理解..所以您的问题是看不到按钮？或者你可以看到它们，但不能按它们？请用截图来了解你的问题
