Images not showing in List Firebase

When using a custom adapter in Firebase, I ran into a problem that everything works, but the pictures in the sheet are not displayed. Something incomprehensible is highlighted, but not her. It is necessary that they be in a normal sheet and they can be seen. I think it's because of the context in Picasso. The guide I followed had a wish(mContext) method that I can't use now. Please help, I don't understand what is the problem. I am attaching the image_item.xml code

Android studio RecyclerView with firebase problem?

If i complete those edit text with what i want,it will show the info to my fire data base but in the recycler view never show the third holder(holder.textViewZ.setText(model.getWhy). Do you have any idea why is this happening?

How do i reset a Card Stack or get the Previous Card?

So, I have followed this tutorial (https://www.youtube.com/watch?v=cS5l_hPwC10) on how to do a card stack and it works fine even with 2 cardstacks at the same time. now I want to add a button so i can reset both stacks and/or a button to get to the previous card
Here is all the code I have related to the card stack. Tell me if you need more since this is the first time I am trying to programm something

ImageView ImgV2 = (ImageView) (ImgcontentView2.findViewById(R.id.image_content2));
ImgV2.setImageResource(getItem(position));
return ImgcontentView2;
}
}

Just keep handles to CardStack instead:
private CardStack cardStack01;
private CardStack cardStack02;
And let the Fragment implement getters and setters for these.

Retrieve data from ListView items

I made a listview with adapter and each listview item contains four RadioButtons.
What I want to do is to have a button on the listview containing activity.And when I click on that button it will retrieve all checkstate of radiobuttons of each item and send them to other activities.
But I don't know how to retrieve that data although I searched a lot . this is the Activity.java file

android:id="#+id/rate_listview"
android:layout_width="match_parent"
android:layout_height="match_parent"/>
<Button
android:id="#+id/the_btn"
android:layout_width="match_parent"
android:layout_height="match_parent"/>
</android.widget.LinearLayout>

Use a model something like
Class Rate{
String title;
int rate;
Rates(String title){
this.title = title;
}
public void setRate(int rate){
this.rate = rate;
}
public String getTitle(){
return this.title;
}
}
Now, inside activity do something like:
List<Rates> rates = new ArrayList<>();
rates.add(new Rates("إيه رأيك في البني آدم اللي شرح الدورة"));
rates.add(new Rates("ايه رأيك في المكان اللي تمت فيه الدورة");
rates.add(new Rates("الجهة المنظمة اللي عملت الدورة"));
rates.add(new Rates("محتوى الدورة"));
rates.add(new Rates("تقييم عام"));
List<String> strings = new ArrayList<>(rates.size());
for (Rate rate : rates) {
strings.add(rate != null ? rate.getTitle() : null);
}
//Initialization of Adapter and ListView and hooking them together
RateAdapter rateAdapter = new RateAdapter(this , titlesArray);
Now, inside adapter class, Handle the Event for radio buttons. To pass data back to Activity, created an interface to update respective index.
interface RadioClickListener{
void radioClicked(int position, int rate);
}
...
RadioClickListener radioClickListener;
...
public RateAdapter(Context context, ArrayList<String> arrayList) {
super(context, 0, arrayList);
this.context = context;
radioClicked = (RadioClickListener) context;
}
So, when you click the ratioButton, item at respective index is updated by calling
//pass the position and rate for that item
radioClickListener.radioClicked(position, "1");
And finally implement the interface to the Activity to update the List.
public class TempActivity extends AppCompatActivity implements RateAdapter.RadioClickListener {
...
#Override
public void radioClicked(int position, int rate){
rates.get(position).setRate(rate);
}
Now, you have the updated rates List, So to pass it to another activity parcel is with the intent and send it.

StaggeredGrid RecyclerView not showing anything

I'm trying to inflate a RecyclerView which has as StaggeredGrid Layout, but it is not showing anything. I've pretty much copied previous code I've used before for the RecyclerView so I'm kind of stumped.
In MuseumStoriesViewHolder.onCreateViewHolder() the return of holder has the following value ViewHolder{337ec22b position=-1 id=-1, oldPos=-1, pLpos:-1 unboundundefined adapter position no parent} I'm not sure if this is realated, but it was something that seemed off to me.
It also might help to know that the fragment I'm inflating this RecyclerView is a nested Fragment.
Any help would be greatly appreciated.
