RecyclerView isn't showed without setLayoutManager, but setLayoutManager makes my program crash. This method was demonstrated in all of the tutorials I have watched. Yeah, I know, there is too much code with a lot of garbage, but the error can be anywhere, so I hope you can help me(
StoreInfoPage.java (get it just like the MainActivity)
public class StoreInfoPage extends AppCompatActivity {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.store_info_page);
RecyclerView lastMonthSellsList = findViewById(R.id.last_month_sells_list);
ArrayList<Product> products = new ArrayList<>();
products.add(new Product(4, 5, true, true, 16000, 12000));
products.add(new Product(4, 5, true, true, 16000, 12000));
StoreSellingAdapter adapter = new StoreSellingAdapter(this, products);
lastMonthSellsList.setAdapter(adapter);
lastMonthSellsList.setLayoutManager(new LinearLayoutManager(this));
}

I really don't know you!
Everything is because of TextView.setText(Int).
Just replace Int with String.valueOf(Int).

So, when I try to refresh list with new items, all views (e.g. all TextView) updates successfully except this tree. The tree becomes a copy of tree in previous card (item) in RecyclerView.
I have such adapter:
public class TransactionsCardAdapter extends RecyclerView.Adapter<TransactionsCardAdapter.TcaViewHolder> {
private Context mContext;

Please, explain me, what I am doing wrong and why this problem happens.

RecyclerView reuses existing views instead of inflating them again. All the fields which are not explicitly updated will hence be copied from some other view. If the child is not being explicitly hidden or updated (like when they are null) old values will be used. So, you will have to add an else case for every child view. Like if some value is null hide it in the else case.
if (item.getStatusConfirmed() != null) {
makeConfirmed(item.getStatusConfirmed(), holder);
} else {
view.setVisibilty(View.GONE);
}

Recyclerview not all data is displayed

hi I am trying to display data in a recyclerview in android by parsing a json from mysql database. But it keeps displaying just some of the data and I can't seem to find the problem.Any help will be greatly appreciated.
This is the adapter:
public class Adapter extends RecyclerView.Adapter<Adapter.MyViewHolder> {
List<Course> data;
private Context context;
public Adapter(Context context,List<Course> data){
this.data=data;
this.context=context;
}
#NonNull
#Override
public MyViewHolder onCreateViewHolder(#NonNull ViewGroup parent, int viewType) {
View view=LayoutInflater.from(parent.getContext()).inflate(R.layout.course_list,parent,false);
return new MyViewHolder(view);
}
#Override
public void onBindViewHolder(#NonNull MyViewHolder holder, int position) {
DecimalFormat form = new DecimalFormat("0.00");
Course current=data.get(position);
holder.tCoursecode.setText(current.getmCoursecode());
holder.tCoursetitle.setText(current.getmCoursetitle());
holder.tCredit.setText(String.valueOf(current.getmCredit()));
holder.tMarks.setText(form.format (current.getmMarks()));
holder.tGrade.setText(current.getmGrade());
}
#Override
public int getItemCount() {
return data.size();
}
class MyViewHolder extends RecyclerView.ViewHolder {
TextView tCoursecode;
TextView tCoursetitle;
TextView tCredit;
TextView tMarks;
TextView tGrade;
public MyViewHolder(View itemView) {
super(itemView);
tCoursecode=itemView.findViewById(R.id.tcc);
tCoursetitle=itemView.findViewById(R.id.tct);
tCredit=itemView.findViewById(R.id.tc);
tMarks=itemView.findViewById(R.id.tm);
tGrade=itemView.findViewById(R.id.tg);
}
}
this the layout:

ExpandableRecyclerview Inside a Cardview Recyclerview

I am totally familiar with ExpandableRecyclerview Or ExpandableLayout But I have a design that is a little bit unique and I am seeking help to achieve this implementation.
I Am Attaching the design
When the user clicks the arrow shown in the image the CardView Recyclerview should expand or inflate a recyclerview in between comment button and response section. How to do that. I have tried the ExpandableRecyclerview from ThoughtBot and ExpandableListView all this components add a child to parent.
I am using ExpandableRecyclerview from Thoughtbot,
com.thoughtbot.expandablerecyclerview
My Adapter Looks like as below.
public class ReviewRecyclerAdapter extends ExpandableRecyclerViewAdapter<ReviewViewHolder, CommentsViewHolder> {
private Context context;
public ReviewRecyclerAdapter(Context context,List<? extends ExpandableGroup> groups) {
super(groups);
this.context = context;
}
#Override
public ReviewViewHolder onCreateGroupViewHolder(ViewGroup parent, int viewType) {
View view = LayoutInflater.from(parent.getContext())
.inflate(R.layout.list_item_review, parent, false);
return new ReviewViewHolder(view);
}
#Override

ListView Items changed automatically in Fragment android

when I scroll the listview the items changed automatically, in other word an item override other item's view like : when I click on favorite button other items has been changed like this
example:
the item that I clicked
I didn't click on this item
here is my code :
CustomListAdapter.java :
public class CustomListAdapter extends BaseAdapter {
private Context context;
LayoutInflater inflater;
boolean isVoter;
public CustomListAdapter(Context c ) {
this.context = c;
}
#Override
public View getView(final int position, View convertView, ViewGroup parent) {
if (convertView == null){
LayoutInflater layoutInflater = (LayoutInflater)context.getSystemService(Activity.LAYOUT_INFLATER_SERVICE);
convertView = layoutInflater.inflate(R.layout.date_view,null);
viewHolder = new ViewHolder();
viewHolder.vote = (ImageButton) convertView.findViewById(R.id.vote);
}else {
viewHolder = (ViewHolder)convertView.getTag();
}
isVoter = newsItemArray.get(position).isVoter();
viewHolder.vote.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
if (!Utility.isNetworkAvailable(context))
Toast.makeText(context, R.string.no_network, Toast.LENGTH_LONG).show();
else
voteBtn( position);
}});
return convertView;
}
public void voteBtn(int position){
if ( !isVoter ) {
viewHolder.vote.setImageResource(R.drawable.button_pressed);
}
else{
viewHolder.vote.setImageResource(R.drawable.button_normal);
}
isVoter = !isVoter;
}
}
private class ViewHolder{
ImageButton vote ;
}
#Override
public int getCount() {
return newsItemArray.size();
}
#Override
public Object getItem(int position) {
return newsItemArray.get(position).getTitle();
}
#Override

return position;
}

isVoter and viewHolder should not be global variables within the Adapter. Meaning, you are not actually changing whatever member is returned by newsItemArray.get(position).isVoter()
Try adding the position to the ViewHolder object. Then pass the ViewHolder object into the constructor of the viewHolder.vote.setOnClickListener. Within the OnClickListener you can then call
isVoter = newsItemArray.get(viewHolder.position).isVoter();
newsItemArray.get(viewHolder.position).setVoter(!isVoter);

Recycler view setLayoutManager Android Studio [duplicate] - android

I really don't know you! Everything is because of TextView.setText(Int). Just replace Int with String.valueOf(Int).
