recyclerview-layout

Any idea how to create a page indicator for recyclerview list ? You can add an indicator by using RecyclerView.ItemDecoration. Just draw some lines or circles at the bottom and use layoutManager.findFirstVisibleItemPosition() to get the current active item. Since pagers tend to fill the whole width this is an accruate way of getting the displayed item. This also allows us to calculate the scrolling distance by comparing the childs left edge to the parents. Below you find a sample decoration that draws some lines and animates between them public class LinePagerIndicatorDecoration extends

I create a RecyclerView list with a default layout. I then add one new item to the list and the layout updates to show the new item. I then navigate to a previous activity. When I return to the RecyclerView activity I am returned to the generic, default list and my new item in the RecyclerView list is gone. So how do I return to the RecyclerView and the new item that I created rather than the generic list? Do I need to add some code that says if the size of the adapter is > 0 then don't create a new list use the existing one? And should I be doing the test in the RecyclerView activity or in

I make small project with RecyclerView with CardView items inside. I created expandable card (expanded by pressing on small button inside the card). Each card always contain visible part (id:top_layout) and expandable part (id:expandable_part_layout). Problem is that when I expand last item or item which after expand has bottom edge below bottom edge of RecyclerView (some part of item or expanded item is invisible to user) the RecyclerView should scroll up all items to show whole item that I expanded. I tried use scrollToPosition and similar methods to scroll to end of expanded card but

I am working on grid layout using recyclerview in android. The grid occupies a portion of the screen and has a shadow. To get the desired shadow effect I am using an elevation value of 12 dp. But it does not seem to work as I cannot see any elevation (shadow) of the grid. Why is this happening? Does recyclerview not support elevation? <?xml version="1.0" encoding="utf-8"?> <RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" xmlns:tools="http://schemas.android.com/tools" android:layout_width="match_parent" android:id="@+id/activity_grid_layout" android:background="

I have RecyclerView having an ImageView and a TextView for each row layout.In ViewHolder in RecyclerViewAdapter, I have click listener as v.setOnClickListener(new View.OnClickListener() { @Override public void onClick(View v) { Images i=list.get(getAdapterPosition()); i.setFlag(!i.getFlag()); list.set(getAdapterPosition(),(i)); notifyDataSetChanged(); } }); In that click listener I am changing Boolean flag such that it can show either an item is selected or not. Depending on it's value I want to Traverse entire ArrayList by checking for(int i=0; i<images.size(); i++){ if(images.get(i).getFlag(
