可以将文章内容翻译成中文,广告屏蔽插件可能会导致该功能失效(如失效,请关闭广告屏蔽插件后再试): 问题: Is there any way to simulate a click on a RecyclerView item with Robolectric? So far, I have tried getting the View at the first visible position of the RecyclerView , but that is always null . It's getChildCount() keeps returning 0 , and findViewHolderForPosition is always null . The adapter returns a non-0 number from getItemCount() (there are definitely items in the adapter). I'm using Robolectric 2.4 SNAPSHOT. 回答1: Seems like the issue was that RecyclerView needs to be measured and layed out manually in Robolectric. Calling this solves

If your use of RecyclerView falls into this category, set this to true. What's that suppose to mean? Can anyone show me the context of using it or explain about the meaning

In the end it should become a booking application so that you can choose between different disciplines and book a certain time slot withing it. However so far I only achieve to do either a ListActivity OR the tabbed activity (the standard one from android studio) but not both. Would be glad if someone could help on this. The tabbed activity: public class Diciplines extends AppCompatActivity { /** * The {

But in my case to avoid that I have tried doing it even on UI thread but still no luck. I am using FirebaseUI for my app. Below is the code snippet: public static void getUserFromUserId ( @NonNull DatabaseReference dbRef , @NonNull String userId ) { dbRef . child ( USERS ). child ( userId ) . addListenerForSingleValueEvent ( new ValueEventListener () { @Override public void onDataChange ( DataSnapshot

ListAdapter not refreshing RecyclerView if I submit the same list with different item order

匿名 (未验证) 提交于 2019-12-03 01:34:02
可以将文章内容翻译成中文,广告屏蔽插件可能会导致该功能失效(如失效,请关闭广告屏蔽插件后再试): 问题: I am using a RecyclerView with ListAdapter (which uses AsyncListDiffer to calculate and animate changes when list is replaced). The problem is that if I submit() some list, then re-order that list, and submit() again, nothing happens. How do I force ListAdapter to evaluate this new list, even though it is "the same" (but order has changed)? New findings: I checked source code of submitList() and in the beggining there is a check: public void submitList(@Nullable final List<T> newList) { final int runGeneration = ++this

RecyclerView: Inconsistency detected. Invalid item position

可以将文章内容翻译成中文,广告屏蔽插件可能会导致该功能失效(如失效,请关闭广告屏蔽插件后再试): 问题: Our QA has detected a bug: when rotating the Android device (Droid Turbo), the following RecyclerView-related crash happened: java.lang.IndexOutOfBoundsException: Inconsistency detected. Invalid item position 2(offset:2).state:3 To me it looks like an internal error inside RecyclerView, as I can't think of any way of this being caused directly by our code... Has anyone encountered this problem? What would be the solution? A brutal workaround could be perhaps to catch the exception when it happens, and re-create the RecyclverView instance
