android-databinding

问题 I get this error when my espresso test runs with android databinding on the fragment layout. I dont see any crash when I use the app. Is there anyway I can avoid this? onCreateView method in fragment: @Override public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) { // Inflate the layout for this fragment SponsorDetailBinding mBinding = DataBindingUtil.inflate(inflater, R.layout.fragment_sponsordetail, container, false); return mBinding.getRoot(); }

问题 I'm trying to use Android Databinding in my Android app. I've an Object Outlet if I initialize the object without any data. Everything works fine. And all data are well collected.

问题 I seem to be getting an error when creating binding expressions in Android Studio. The code seems to compile and run ok and the method is called, but I'm still left with an error in Android Studio. Am I missing something here? As far as the documentation is concerned I don't think I am. 回答1: Android Studio is following data binding implementation and may show warnings or errors where there is no problem. It should keep improving. 来源： https://stackoverflow.com/questions/42187405/binding

问题 I am developing an Android app in Xamarin.Android(C#). However, i do feel that this question can also be answered by any Java devs as well. I am new in android development. Anyways, i created a fragment with just a LinearLayout and a TextView inside it. When i create the background class for it, i don't inherit(on in JAVA's word, extend ) it from the Fragment class but rather from the LinearLayout class. So, the MyFragment.cs file starts like this : public class MyFragment : LinearLayout The
