android-viewholder

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. When I clicked on an unlocked checkbox everything works as normal it check the box and un-checks the box fine. The problem comes as soon as I click

问题 I'm using a RecyclerView to display some data. For each item in my RecyclerView I have created a custom layout which holds beside other views a RecyclerView. So I have a nested RecyclerView under each item. <RelativeLayout android:layout_width="match_parent" android:layout_height="match_parent"> <android.support.v7.widget.RecyclerView android:layout_width="180dp" android:layout_height="45dp" android:id="@+id/recycler_view"/> //Other text views </RelativeLayout> The layout for the inner

问题 In my android project, I created Generic RecyclerView's Adapter class & Viewholder class like below, Adapter class, public class BaseRecyclerViewAdapter extends RecyclerView.Adapter<BaseViewHolder> { private ItemClickListener itemClickListener; private List<? extends Object> objectArrayList; private int layout; private BaseViewHolder baseViewHolder; public BaseRecyclerViewAdapter(int layout, ItemClickListener itemClickListener, List<? extends Object> objectArrayList) { this.layout = layout;

问题 I am having a listview in my app. Each listview row expands on tap and a hidden view becomes visible but problem is that hidden view also becomes visible for many others items in the list. I know the reason for this behaviour but I don't know how to resolve it. Here is my adapter class public class ScheduleTaskAdapter extends BaseAdapter { Context context; LayoutInflater layoutInflater; // List<InterestAndLanguageBean> interestAndLanguageBeans=new ArrayList<>(); List<BirdsDataBean> imageList

问题 I've investigated several SO answers on this question (here, here, and here) and none of the proposed solutions have worked. My problem is that my RecyclerView list items aren't being displayed. I've set breakpoints in MessengerRecyclerAdapter, onCreateViewHolder, onBindViewHolder, and getItemCount and only the first one is ever called. While in a breakpoint I've entered the expression evaluator and executed MessengerRecyclerAdapter.getItemCount(); And received the expected answer of 20. The

问题 Can the RecyclerView.ViewHolder be used not as a inner class? Are there any issues on doing so? I have searched around but havent found any documentation on it! 回答1: Actually, I think a ViewHolder should either be a static nested class (mind the static!) or a top-level class (which actually will be no different, just the class name will contains the outer class name followed by a $ and then the inner class name). Why do I think so? When the ViewHolder is a non-static inner class of the

问题 I'm reading data into my listview from a database and i can see the information in the listview, the data in each row is split into left and right. When i scroll in the listview the items are not uppdating correctly. Some items in the right side off the listview are moving to the left side and the other way around. I can make this problem go away by setting convertView = null directly under the getView() which is a very bad solution! How to solve the problem properly? Code links: Xml "http:/

问题 I was recently playing a little bit with the RecyclerView and the concept of ViewHolder's in Android 5+. The adapter implementation handles quite a large dataset (i.e ~ 60 000 items), requested from the internet upon onBindViewHolder(...) call. The network requests are handled by the volley library and the response represents the data model used to fill up the view holder. Now when fast-flinging (i.e motion with a velocity, different than swipe where a user touches the device and moves slowly

问题 It is my third day now dealing with the handling of my view clicks. I originally was using ListView , then I switched to RecyclerView . I have added android:onclick elements to every control on my row_layout and I am handling them in my MainActivity like this: public void MyMethod(View view) {} In my old ListView implementation, I have done setTag(position) to be able to get it in MyMethod by doing this inside it: Integer.parseInt(view.getTag().toString()) This worked nicely without problems.

问题 I can't figure out where am I wrong. I have created a button inside my custom ListView Adapter, I have implemented the ViewHolder pattern and set up an OnClickListener for the button. The problem is, whenever I click on the button on any row, I get the same result for clicks. Same title, same username. What else to I need to set up? Thanks and Merry Christmas!
