And my Fragment code to load
dataAdapter = new rutaSelAdapter(lista, new onItemClick() {

});
rlista.setLayoutManager(new LinearLayoutManager(getContext(), LinearLayoutManager.HORIZONTAL, false));
rlista.setAdapter(dataAdapter);
And my dataAdapter class
public class rutaSelAdapter extends OmegaRecyclerView.Adapter<rutaSelAdapter.ViewHolder> {
public List<Ruta> lista;
private onItemClick onItemClick;
private Ruta selectedItem;
public rutaSelAdapter(List<Ruta> l, onItemClick onclick) {
lista = l;

}

}
notifyDataSetChanged();
}
public void deleteData(Ruta rx) {
//ToastHelper.normal("Se a eliminado el horario " + rx.getHora());
lista.remove(rx);
notifyDataSetChanged();
}
public class ViewHolder extends SwipeViewHolder implements View.OnClickListener {
private final TextView tnombre;
private LinearLayout linearFondo;
HorarioDao horarioManager = AppController.daoSession.getHorarioDao();
private Ruta currentItem;
public ViewHolder(ViewGroup itemView) {
super(itemView, R.layout.ruta_sel_template, SwipeViewHolder.NO_ID, SwipeViewHolder.NO_ID);
tnombre = findViewById(R.id.tnombre);
linearFondo = findViewById(R.id.linearFondo);
contentView.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
setSelectedItem(currentItem);
onItemClick.onClickItemList(v, getAdapterPosition());
}
});
}
private Ruta backItem;
private void setSelection(Ruta rx){
//if (backItem == null)
}
#Override
public void onClick(final View v) {
}
public void display(Ruta rx) {
currentItem = rx;
if (rx.getNombre() == null) tnombre.setText("");
else tnombre.setText(rx.getNombre().toString());
}
}
}
In Android Studio show me right as I want.
But in runtime, in my mobile the items have full width but wrap content.enter image description here

i think you just add notifyDataSetChanged in your class adapter
public rutaSelAdapter(List<Ruta> l, onItemClick onclick) {
lista = l;
this.onItemClick = onclick;
if (l.size() > 0)
setSelectedItem(l.get(0));
notifyDataSetChanged();
}

In your recyclerview item layout update width of these 2 textviews [tnombre and thorarios] to wrap_content
<LinearLayout
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="center_vertical"
android:layout_marginLeft="5dp"
android:orientation="vertical">
<TextView
android:id="#+id/tnombre"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:ellipsize="end"
android:inputType="textMultiLine"
android:lines="1"
android:textAppearance="#style/TextAppearance.AppCompat.Medium"
android:textSize="12sp"
android:textStyle="bold"></TextView>
<TextView
android:id="#+id/thorarios"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="center_vertical"
android:textAppearance="#style/TextAppearance.AppCompat.Small"
android:textColor="#color/colorPrimary"
android:textSize="10sp"
android:visibility="gone"></TextView>
</LinearLayout>

If someone else have this issue, I fixed adding this line in the fragment class.
rlista.setHasFixedSize(true);

My recycler view doesn't show all items that it has, how can I fix it?

I have something wrong with recyclerView. It doesn't show all items. For example, recyclerView has 12 items, but it shows like 10 with a half items. I can set paddingBottom for it, and it shows all items, but I don't think it is a good way. How can I fix it? I think maybe it becouse of my buttons above it.

Try adding app:layout_constraintBottom_toBottomOf="parent" in the recycler view and also make the height of the recycler view to be 0dp (match_constraint).

Why there is an error in setOnItemClickListener

I use fragment and I want to set listview in m fragment.I have error in this field.
I want to use ListView of Foldingcell, but I think I have an error in my adapter.
i can not find error.
any body can't help me?
what should I do?
this is my error:

It looks like your error is in the setAdapter not the onItemClickListener.
My guess is that ListView lvlist = (ListView) view.findViewById(R.id.lvlist); return null;
Check if "R.id.lvlist" is realy the id of your listView in the xml file.
Also, Check if "lvlist" is null after the findViewById line of code
