kandi X-RAY | epoxy Summary

epoxy is a Java library typically used in User Interface, RecyclerView applications. epoxy has no bugs, it has no vulnerabilities, it has build file available, it has a Permissive License and it has high support. You can download it from GitHub, Maven.

Epoxy is an Android library for building complex screens in a RecyclerView. Models are automatically generated from custom views or databinding layouts via annotation processing. These models are then used in an EpoxyController to declare what items to show in the RecyclerView. This abstracts the boilerplate of view holders, diffing items and binding payload changes, item types, item ids, span counts, and more, in order to simplify building screens with multiple view types. Additionally, Epoxy adds support for saving view state and automatic diffing of item changes. We developed Epoxy at Airbnb to simplify the process of working with RecyclerViews, and to add the missing functionality we needed. We now use Epoxy for most of the main screens in our app and it has improved our developer experience greatly.

            Python: Program Outputs Different Values Every Time It Runs
            Asked 2022-Apr-17 at 07:58

            This problem has been occurring for a couple months now with any project that uses complicated sets of equations (such as for composite mechanics analysis or thrust/fluid flow analysis). Simple calculations, iterative methods, and Numpy matrices seem to work fine on their own though. And just to be sure, I have tried completely uninstalling and reinstalling Python and Pycharm, but the same problem persists.

            For the past couple months, any code that incorporates more complex mathematics, such as those described above, will output different values despite all input values and calculations being constant. The different codes have no means of variation or randomness. I've noticed these incorrect outputs usually occur within arrays/matrices, and I can tell the output values are incorrect because the expected numbers are instead absurdly large.

            For example, an element within a matrix is expected to be 5.197e+7, but instead, the code outputs 3.322e+257 for that same element. However, upon running the code a second time, the code produces an output of 2.822e+204 for the exact same element. Only upon the third run does the code output the correct value for that element, which is 5.197e+7. This process can take anywhere from 1 to 15 separate runs for the same, unchanging code in order to output the correct value.

            Another interesting aspect is that the calculations I am coding usually require multiple iterations of said code. However, even though I am resetting the arrays that temporarily save all values (other than final values that no longer affect the calculations), whatever is causing these "errors is being carried through the code until the end of the iterations. To my understanding, this shouldn't be the case since, at the end of an iteration, the code is setting all values, other than the known initial values, to 0 and recalculating. This would mean that the code is continuously making the same error.

            Below are some examples of the program's expected output vs actual outputs.

            I don't know if it's the cause of your problem, but your code has six calls to np.empty. I don't see any later initialization of these arrays.

            np.empty causes the array to not be initialized, and the memory will contain random garbage. Try replace those with np.zeros and see if you get better results.

            MediaController for VideoView inside BottomSheetDialog is hidden behind the BottomSheetDialog
            Asked 2022-Mar-17 at 15:01

            I have a project where I programmatically add custom map markers to a Maps activity. When a user clicks on a marker, a BottomSheetDialog comes up from the bottom of the screen, and contains information about the custom map marker. One of the key pieces of information is a video that will play. The problem is that the MediaController for the VideoView doesnt hover above the video, but is behind the BottomSheetDialog. It is in the correct place on the screen, but behind both the BottomSheetDialog and the VideoView. I am using EpoxyRecyclerView to add the VideoView, MediaController and various TextView to the BottomSheetDialog.

            I'm currently using the Epoxy library instead of RecyclerView. However, since Epoxy is built on the basis of RecyclerView, let's just call it RecyclerView.

            In the code, the type of the lambda is mismatched, how does it work?
            Asked 2021-Oct-18 at 20:36

            I'm using the Epoxy library on Android.

            What I'm curious about is why the parameter of the lambda expression doesn't get an error when the type doesn't match.

            The listener is a lambda expression that takes an Int type as a parameter.

            But listener(addDetailClicked) works normally.

            Shouldn't it be listener(Int)? or listener({ i -> addDetailClicked(i) }).

            Is the automatic comparison in the Epoxy library based on DiffUtil?
            Asked 2021-Oct-08 at 22:25

            I came across the Epoxy library while looking for information about RecyclerView.

            Epoxy is a library that makes RecyclerView easier to use.

            I haven't applied it to my app yet, but I think it will be easier if I apply it.

            Because the RecyclerView I use is based on two view types, and both items are dynamically added/removed frequently (DiffUitl is also used).

            However, while reading the description of the Epoxy library in Git,

            I came across the following:

            Additionally, Epoxy adds support for saving view state and automatic diffing of item changes.

            I'm curious as to what automatic diffing you're talking about here works based on. Is it DiffUtil internally or simply notifyDatasetChanged()?

            If it uses DiffUtil then I'm going to use Epoxy or I'll consider it.

            ...

            ANSWER

            Answered 2021-Oct-08 at 22:25

            or simply notifyDatasetChanged()?

            They are not using notifyDatasetChanged() as per the documentation:

            Epoxy's automatic diffing to reduce the overhead, while also efficiently only updating the views that changed.

            Is it DiffUtil internally

            DiffUtil is used for the EpoxyController class, but not for EpoxyAdapter class, the documentation says:

            The Android Support Library class DiffUtil is used for diffing in EpoxyController. For legacy reasons, the older EpoxyAdapter uses a custom solution for diffing.

            So, As you still designing your app, I expect that you'll be using EpoxyController rather than the legacy EpoxyAdapter; and therefore, DiffUtil is already utilized.

            If it uses DiffUtil then I'm going to use Epoxy or I'll consider it

            It's up to you; using libraries in general has pros and cons in terms of continuity, security, limitations, complexity .. etc.
