recycler-adapter

What I am trying to create is a horizontal scrolling image gallery. I have a RecyclerView (support 22.0.0). The problem I am having is that when I scroll to the end and then scroll back, usually one image will be missing sometimes two. Strangely when I keep swiping back and forth, a different image could be missing. Here is the layout for the item: <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="fill_parent" android:layout_height="160dp"> <ImageView android:id="@+id/product_variation_image" android:layout_width="match_parent" android:layout_height

I am trying to add a simple Click View to an item of a recycler view, but for some reason I have to click on an item twice instead of once to perform an action. On single click it seems like that recycler View does not detect a click. On the next one however it detects the click and performs a suitable action. XML : <android.support.v7.widget.CardView xmlns:android="http://schemas.android.com/apk/res/android" android:id="@+id/cardView" android:layout_width="match_parent" android:layout_height="wrap_content" > <RelativeLayout android:id="@+id/rlContainer" android:layout_width="match_parent"

I have got this stack trace though crashlytics. I have no idea where the issue is. Is there any alternative of StaggeredGridLayoutManager that I can use to get a listview like layout. Fatal Exception: java.lang.ArrayIndexOutOfBoundsException: start < 0 || end > len. start=-1, end=11, len=11 at java.util.Arrays.checkStartAndEnd(Arrays.java:1745) at java.util.Arrays.fill(Arrays.java:803) at android.support.v7.widget.StaggeredGridLayoutManager$LazySpanLookup.invalidateAfter(SourceFile:2404) at android.support.v7.widget.StaggeredGridLayoutManager.handleUpdate(SourceFile:1373) at android.support.v7

I am trying to develop e-commerce type of app in which user can add item to cart. But I am unable to update the cart badge counter from adapter. Here is screenshot of my app. I am using Recycler view inside fragment. And I am referring this below link for menu item count. https://mobikul.com/adding-badge-count-on-menu-items-like-cart-notification-etc/ My problem is I cannot access menu item from adapter. Here is my fragment code. PriceListFragment.java public class PriceListFragment extends Fragment { public ArrayList<Design> designList; private Single_DesignAdapter adapter; private

I'm having a problem with using the notifyItemMoved() method. It seems to be incorrectly displaying unmoved views. My list has 4 element in it. What I want to do is animate a swap between item 1 and item 3. Items 1 and 3 swap correctly, but item 2 displays what was at item 3! So the list starts off looking something like this: Item 0 Item 1 Item 2 Item 3 And ends like this: Item 0 Item 3 Item 3 <!-- What the heck has this changed for? Item 1 My adapter is backed by a List mProductList . I call the following code: public void sortBackingListUsingSortingList(List<ProductWrapper> newProductItems)

What is the best strategy to achieve this feature: I Have a horizontal RecyclerView with cards. Each card will fulfil the entire screen, but I want it to show part of the next card and previous one if it has more than one item. I know I can achieve this by setting my card android:layout_width at the adapter to have a specific DP like 250dp instead of match_parent . But it doesn't look like a proper solution. This is my code: Activity with RecyclerView: class ListPokemon : AppCompatActivity() { override fun onCreate(savedInstanceState: Bundle?) { super.onCreate(savedInstanceState)
