android-recyclerview

问题 I have multiple lists in my Android app, the activities that contain those (recycle) listviews also contain other content. Putting a listview below the content works fine without any custom modelling. However, when scrolling in the list, it is only scrolling the list, thus showing about 1 or 2 items, while we would like to scroll the whole activity, so that the content moves up and the complete list is shown. To make an activity scrollable, we would need a ScrollView, this goes a bit against

问题 I have a RecyclerView that displays a list of images and text that are downloaded from the internet via a RecyclerView adapter. The problem arises when I scroll up and down the RecyclerView. As I scroll down the list initially, everything seems fine and all the CardViews (a cardview containing an image and some text) are in their respective positions. However, as I begin to scroll back up, all the previous CardViews are replaced by the lowest CardView. The lowest item of the recyclerview is

问题 I've been trying to find out how I could check if a checkbox was checked in a list item in a RecyclerView. I have seen some articles online but I could not understand what they meant. If anyone could help, that'd be great. Info about my app This is a little snippet of what it does. It is a contacts app. On one screen it lists out ALL of the user's contacts. I didn't use the contacts picker for this. I displayed the list as a recyclerview, each item in the recyclerview has a checkbox. The user

问题 I am building a notifications list for an application I'm working on and I'm having trouble finding a way to take my list of notifications from the server and displaying them in separate lists in a RecyclerView. The end product would display the list of notifications with headers for Recent notifications and Older notifications, a la: <RECENT HEADER> <NOTIF-1> <NOTIF-2> <OLDER HEADER> <NOTIF-3> <NOTIF-4> <NOTIF-5> <NOTIF-6> except instead of angle-bracket text it's actual views representing

问题 I have a problem with my recyclerViev , specifically with the scrolling. I have some list, which is updated in real time, some item is added, some removed, and everything is sorted by some parameter. So the item which was initially first on the list, can have its parameter changed, which will be in different position after the sorting. So my recyclerView is for example focusing on the initial item, and after change, when some item has "better" parameter is changing position with that initial

That works well when accessing Firebase Realtime DB data as explained here: https://github.com/firebase/FirebaseUI-Android/blob/master/database/README.md#using-firebaseui-with-indexed-data But what about accessing Firestore data? It seems that FirestoreRecyclerAdapter does not support indexed queries via setIndexedQuery(keyref, dataref, ... ) How can I maybe execute the data query manually inside the

问题 Currently I have a RecyclerView with a check box that can have three states. ticked, unticked or Locked. I understand I can make a custom view state. The question is more understand the behavior and of the recyclerview view holder binding. When the RecylcerView loads everything works as expected everything is unticked except for the locked items.
