问题 I have a recycler view with ItemTouchHelper. It allows dragging the items. I want to limit the dragging to the bounds of recycler view - i.e. you can't just drag the view outside the container, so that it disappears. I tried checking the absolute coordinates like this: @Override public void onChildDraw(Canvas c, RecyclerView recyclerView, RecyclerView.ViewHolder viewHolder, float dX, float dY, int actionState, boolean isCurrentlyActive) { recyclerView.getLocationOnScreen(pos); int rvY = pos[1

问题 I have a recycler view with StaggeredGridLayoutManager. Within in I have custom items/views. Each item is defined as a ConstraintLayout where there is an image which is supposed to have a constant aspect ratio. But the image is to still be able to scale to fit the width of each span. And then the height should be adjusted according to the ratio. But somehow the images are not maintaining the aspect ratio. Here are the xml files and code to create the recycler view: item.xml <?xml version="1.0

问题 I've been dealing with a strange behavior in Recycler View, if the view count in the adapter is small, in my case with size 5, the views are not being recycled and onBindViewHolder is not called when the view is scrolled back to screen. If i increase the size to 10 views for example, then recycling starts working and onBindViewHolder is called every time a view enters the screen.
