recyclerview items size not the same size in layout
I'm trying to make a nested recyclerview with multiple items and after finishing the adatper and design and going in testing I got this in the emulator
I didn't understand why items appears like that, the items not the same height and width which I make it for the design of it's layout.
here is the code for recyclerview setup
mRecyclerView.setHasFixedSize(true);
adapter = new CheckoutMainRecyAdapter(CheckOutActivity.this, allSampleData);
mRecyclerView.setLayoutManager(new LinearLayoutManager(CheckOutActivity.this));
mRecyclerView.setAdapter(adapter);
and here is the adapter code
public class CheckoutMainRecyAdapter extends RecyclerView.Adapter<RecyclerView.ViewHolder> {
private ArrayList<CheckoutMainModel> dataList;
private Context mContext;
public CheckoutMainRecyAdapter(Context context, ArrayList<CheckoutMainModel> dataList) {
this.dataList = dataList;
this.mContext = context;
}
@Override
public RecyclerView.ViewHolder onCreateViewHolder(ViewGroup viewGroup, int i) {

Solution
- You have to supply the recycler as the root to the inflate method, so that the inflated view gets the correct layout parameters from the parent
- You have to set attachToRoot to false, because the recycler view handles the attaching.
Example:
view = LayoutInflater.from(viewGroup.getContext()).inflate(R.layout.your_layout, viewGroup, false);
