Android Studio中SETAFFINITY ret=-1的含义是什么？这是我的活动日志

在下面的代码中，我在autocomplete_next TextView中设置了新的意图，但在我的手机中，当我运行应用程序时，当我尝试移动到下一个活动时，它不会进入下一个活动，相反，它会再次返回到相同的前一个活动。在Android Studio LOGCAT中，我看到了

RenderScript:SETAFFINITY ret=-1

。我在谷歌上找不到这个错误的线索？请帮我解决我的问题。提前谢谢你

activity_calculator.xml

LOGCAT

您可以添加活动的完整代码吗？这是我的完整代码添加了调用活动和带有XML布局的调用活动。似乎还有第三个活动称为“AlarmActivity”，但您没有为其提供代码。您是否在这一行“label_text=findviewbyd（R.id.label_textView）；”中输入了错误？Bkoz没有像“label\u textView”这样的id，我运行您的代码，从Calculator活动到AutoCompleteTactivity的转换工作正常。
