Question

应用程序在onclick上一直崩溃。调试中没有错误。在editor.apply（）或开始下一个活动时崩溃。无法弄清楚原因。当它崩溃时，它会转到白色屏幕，然后重新加载主要活动。使用android studio和kindle。试过模拟器，它仍然没有工作。尝试重写和检查权限没有任何效果。应用程序的其余部分工作正常，我在其他活动中访问共享首选项。任何帮助都很好。谢谢。

我认为问题在于你正在创建很多Editor对象的实例。

尝试这样做：

SharedPreferences settings = PreferenceManager.getDefaultSharedPreferences("info",Context.MODE_PRIVATE);
 SharedPreferences.Editor editor=settings.edit();
     editor.putString("sex", malefem);
     editor.putString("username", name);
     editor.putString("pin", pin);
     editor.putString("email", email);
     editor.putString("phone", number);
     editor.putString("age", age);
     editor.apply();

崩溃的应用程序。 Android系统。 OnClick共享首选项
