Android 使用带有片段的活动绑定服务
我对绑定服务有疑问。我有父活动和几个片段，我用活动绑定和解除绑定服务，现在我可以在片段中访问该服务了吗？我需要在片段中使用ServiceConnection。是的，您可以通过以下方式访问片段中父活动的服务：Android 使用带有片段的活动绑定服务,android,android-fragments,android-service,Android,Android Fragments,Android Service,我对绑定服务有疑问。我有父活动和几个片段，我用活动绑定和解除绑定服务，现在我可以在片段中访问该服务了吗？我需要在片段中使用ServiceConnection。是的，您可以通过以下方式访问片段中父活动的服务： getActivity().getMyService() 是的，您可以通过以下方式访问片段中父活动的服务： getActivity().getMyService() ===============在您的活动中================= callbackFragmentSe
