问题 I am using Firebase UI FirebaseRecyclerAdapter to populate a RecyclerView. I managed to get click events from components of my item view (the title), but not for anywhere in the item view, which is what I need. I followed google sample. In my Activity: private void setRecyclerView() { recyclerView = (RecyclerView) findViewById(R.id.recycler_view_gigs); recyclerView.setHasFixedSize(true); recyclerView.setLayoutManager(new LinearLayoutManager(this)); mAdapter = new FirebaseRecyclerAdapter<Gig,

问题 I have RecyclerView with images. It based on this solution. Images are lazy loaded into view with Glide. I need to add zoom on central image like in this: How can i do it? 回答1: The most direct way to affect what you want is to extend LinearLayoutManager . As you've no doubt discovered, hooking into the scroll events properly is a pain: So let's extend the manager. We'll create a few parameters that you might expose. public class ZoomCenterCardLayoutManager extends LinearLayoutManager { //

问题 I am using Glide 3.7.0 with RecyclerView . The item view always blinks when refreshing (calling notifyDataSetChanged ). Here is my code: Glide .with(context) .load(filepath) .diskCacheStrategy(DiskCacheStrategy.NONE) .skipMemoryCache(true) .dontAnimate() .into(imageview); When I use no cache, the ImageView has a null Bitmap when notifyDataSetChanged method is called and Glide hasn't finished loading the bitmap. If I use the code below: Glide .with(context) .load(filepath) .dontAnimate() .into

问题 I've got a remove on swipe, that draws a background (much like the Inbox app), implemented by an ItemTouchHelper - by overriding the onChilDraw method and drawing a rectangle on the provided canvas: ItemTouchHelper mIth = new ItemTouchHelper( new ItemTouchHelper.SimpleCallback(0, ItemTouchHelper.RIGHT) { public void onSwiped(RecyclerView.ViewHolder viewHolder, int direction) { remove(viewHolder.getAdapterPosition()); } public boolean onMove(RecyclerView recyclerview, RecyclerView.ViewHolder v

问题 I am getting a weird scrolling behavior when I add a RecyclerView inside a NestedScrollView. What happens is that whenever the scrollview has more rows than can be shown in the screen, as soon as the activity is launched, the NestedScrollView starts with an offset from the top (image 1). If there are few items in the scroll view so that they can all be shown at once, this doesn't happen (image 2). I am using version 23.2.0 of the support library. Image 1 : WRONG - starts with offset from the

问题 I think I've read pretty much all the answers to all of the similar SO questions, and NONE of them seem to be working for me. It's driving me nuts, and I've spent too much time on this. I'm implementing a RecyclerView here and I can't for the life of me update it's children. What happens is that after I update nothing changes on the screen, UNLESS I start scrolling. Once I scroll it updates perfectly . This is my code: public void updateDataAtIndex(final int indexToUpdate, ReadableMap
