Your alertDialog is created before public boolean onJsAlert(...) method called and when it's called second time you got AndroidRuntimeException: requestFeature() must be called before adding content because of you can't use requestWindowFeature() with created dialog. 您的alertDialog是在调用public boolean onJsAlert(...)方法之前创建的，并且在第二次调用时，您遇到了AndroidRuntimeException: requestFeature() must be called before adding content由于无法在创建的对话框中使用requestWindowFeature() ，因此AndroidRuntimeException: requestFeature() must be called before adding content 。 You have to create new instance of dialog in this method or reuse global defined dialog. 您必须使用此方法创建对话框的新实例或重新使用全局定义的对话框。
