Code:

StaggeredGridLayoutManager  manager = new StaggeredGridLayoutManager(2, StaggeredGridLayoutManager.HORIZONTAL);
mRv.setLayoutManager(manager);
mRv.addItemDecoration(new DividerItemDecoration(getActivity(), DividerItemDecoration.HORIZONTAL_LIST), DividerItemDecoration.HORIZONTAL_LIST);
mAdapter = new HomeAdapter(this, list);
mRv.setAdapter(mAdapter);

Then recyclerview no adapter attached appears; skipping layout

And then check a variety of methods did not solve, a lot of online statements. But it still hasn’t solved the problem

StaggeredGridLayoutManager  manager = new StaggeredGridLayoutManager(2, StaggeredGridLayoutManager.HORIZONTAL);
mRv.setLayoutManager(manager);
mAdapter = new HomeAdapter(this, list);
mRv.setAdapter(mAdapter);
mRv.addItemDecoration(new DividerItemDecoration(getActivity(), DividerItemDecoration.HORIZONTAL_LIST), DividerItemDecoration.HORIZONTAL_LIST);

I saw an example later. The code for finding the split line is called

after setAdapter.

Then try it, and it’s OK
