问题 I have a fragment, which contains a recyclerview. This recyclerview is managed with an adapter that includes the viewholder pattern. In the fragment I have a "Save" button, this button must check that no TextInputEditText is empty in the list. The problem is that I can not access the TextInputEditText of the adapter. ViewHolder is only accessible from the "onBindViewHolder" method. I tried to access from fragment in a way: for (int i = 0; i < employeeList.size(); i++) { View employeeView =

问题 I followed Vilen's excellent answer on SO: Put an indeterminate progressbar as footer in a RecyclerView grid on how to implement an endless scroll recyclerview with ProgressBar. I implemented it myself and it works but I would like to extend the example. I want to add extra items at the top of the recyclerview, similar to how Facebook does it when you add a new status update.

问题 Closed. This question is off-topic. It is not currently accepting answers. Want to improve this question? Update the question so it's on-topic for Stack Overflow. Closed last year . I used to SwipeToDismiss library but now I'm trying to migrate to RecyclerView and things are not so obvious, do you know any replacements for this lib?

问题 I have list item with EditText in it, I don't know how many items there will be. I have a problem when I enter some text in EditText , and then scroll down a RecyclerView , after I've scroll up again there is no text in my first EditText . I am wondering what, and where should I write code so that while the user is typing or finished typing (I was thinking to do that with a TextWatcher ) in the EditText the text gets saved into into a file (I'll save it in a .txt file in the external storage)

问题 I am trying to use a RecyclerView as a horizontal ListView . I am trying to figure out how to highlight the selected item. When I click on one of the items, it gets selected and it is highlighted properly but when I click on another one, the second one gets highlighted with the older one.

问题 I'm trying to work with the new RecyclerView , but I could not find an example of a RecyclerView with different types of rows/cardviews getting inflated. With ListView I override the getViewTypeCount and getItemViewType , for handling different types of rows. Am I supposed to do it like the "old" way or should I do something with LayoutManager ?

问题 I need to implement a horizontal listview in my Android application.
