I want to build a grid like the one in Pinterest app on Android.
I started extending an AdapterView<ListAdapter>
but I cannot make many things working (for example the overscroll effect) so, after abandoning the idea to extend AbsListView
, now I am starting thinking it is better to extend a ListView
and override the layoutChildren()
method.
What do you think?
Thanks
We won’t be needing any external library for this as Android’s native RecyclerView makes implementing a Pinterest masonry layout simply by changing the RecyclerView’s Layout Manager
mRecyclerView.setLayoutManager(new StaggeredGridLayoutManager(2, StaggeredGridLayoutManager.VERTICAL));
RecyclerAdapter adapter = new RecyclerAdapter(this);
mRecyclerView.setAdapter(adapter);
Cool. it's Very easy ,but margin on my LinearLayout didn’t seem to work. So here’s a quick fix.
SpacesItemDecoration decoration = new SpacesItemDecoration(16);
mRecyclerView.addItemDecoration(decoration);
SpacesItemDecoration class:
public class SpacesItemDecoration extends RecyclerView.ItemDecoration {
private final int mSpace;
public SpacesItemDecoration(int space) {
this.mSpace = space;
}
@Override
public void getItemOffsets(Rect outRect, View view, RecyclerView parent, RecyclerView.State state) {
outRect.left = mSpace;
outRect.right = mSpace;
outRect.bottom = mSpace;
// Add top margin only for the first item to avoid double space between items
if (parent.getChildAdapterPosition(view) == 0)
outRect.top = mSpace;
}
}
