由 好久不见. 提交于 2019-12-08 07:42:49
问题 My Scenario is very similar to this Image: Flow of the app will be like this: View needs to get updated. Create an observable using RxAndroid to fetch the data from cache / local file. update the view. Make another network call using Retrofit and RxJava to update the view again with new data coming from the web services. Update the local file with the new data. So, I am updating the view twice(One from local file and just after that through webservices) How can I achieve the result using

Drop delete trigger for Room database

由 点点圈 提交于 2019-12-08 04:13:06
问题 I am using room database to store comments and RxJava as a listener to do some stuff when the database is changed. I want to not call the callback when delete is called on the table, only when insert is called. What i found out so far is that Room library has triggers that are called on delete , insert and update of the table that in turn call RxJava's methods. Is there any way to drop the delete trigger and get callbacks only for the insert and update methods? Here is my CommentDAO: @Query(

RxJava: How to express doOnFirst()?

由 时光总嘲笑我的痴心妄想 提交于 2019-12-07 15:48:27
问题 I am using RxJava and I have an Observable with multiple items inside. What I would like to do is run function A on the first item, function B on all of them and function C when the Observable is completed: -----1-----2-----3-----|--> | | | | run A | | | | | | | run B run B run B | | run C is there a clever way of expressing this with lambda functions? I have the following solution already, but it looks ugly and I suspect that there is a better way to do this: observable.subscribe( new

What is the MutableLiveData equivalent in RxJava?

We certainly can use a combination of publish() , refcount() and replay() to achieve the core of the MutableLiveData observable behavior. That said, what would be the analogous counterpart of mCurrentName.setValue() as it pertains to detecting a change and emitting the corresponding event? public class NameViewModel extends ViewModel { // Create a LiveData with a String private
