Dynamically Setting a Fixed Height for a Staggered Grid View

阅读更多关于 Dynamically Setting a Fixed Height for a Staggered Grid View

问题 I'm trying to take a RecyclerView with a StaggeredGridLayout and make it a fixed height by having it measure the views and set the height dynamically. I'm overriding the onMeasure() , but it does not always seem to measure correctly. I'd say it works about 50% of the time. The other 50% of the time it under measures it. I think it has to do with when the text wraps in the view_tile_small.xml , but I'm not sure. Fragment public class AtTheMuseumFragment extends Fragment implements

问题 I have a staggered grid that has 2 columns. This is working. What I want is at position 0 for the row to span across the 2 columns. I have done this before quite easily using GridLayoutManger as so: mGridLayoutManager.setSpanSizeLookup(new GridLayoutManager.SpanSizeLookup() { @Override public int getSpanSize(int position) { return position == 0 ? 2 : 1; } }); StaggeredGridLayoutManager doesn't provide me with this functionality like GridLayoutManager does. Is there a different way of doing

I'm trying to implement a facebook like, gallery grid, where items have different sizes: I was trying to use different libraries/solutions but for now without success: I tried to use AsymemetricGridView . But the problem with this implementation is that there are empty dead spaces left in the grid after going throw the adapter. I also thought of using the StaggeredGridLayoutManager and a RecycleView , but items, in this case, don't have equal or half sizes to other items as it implemented in the Facebook gallery. Now I thinking of providing different view holders for different cases in the

问题 I’m using a staggered recycler view layout for a list of photos. I want the spacing on the sides to be zero while still having space between the two columns. I’m using an item decoration sub class to get the spacing seen in the attached photo. I know I have control over the left and right spacing but the problem is that I never know which column the photo is in. It seems like the staggered layout manager does some of its own reordering. I've tried using getChildAdapterPosition but it seems to
