RecyclerView displaying wrong data in other positions

I am creating a RecyclerView with Card view
my json data contains movie name,year,rating
my card view contains three text fields moviename,rating,year
when i click on rating field it should get the data from the json and display rating beside the rating text field, but the problem here is when i click on text field the data of my card view is displayed on other positions of the card view also.

public class ViewHolder extends RecyclerView.ViewHolder {
TextView view_container;
TextView something;
public TextView textTitle, textRating, textYear;
public ViewHolder(#NonNull View itemView) {
super(itemView);
view_container = itemView.findViewById(R.id.textView5);
something = itemView.findViewById(R.id.Rating);
textTitle = itemView.findViewById(R.id.title);
textRating = itemView.findViewById(R.id.textView2);
textYear = itemView.findViewById(R.id.main_year);
}
}
}

Never bind data with view inside onCreateViewHolder method as you have done this on click of something' ,holder.textYear.setText(g);`
So instead of managing it like this, I suggest you to manage your rating textview with visibility.
Just move your click action inside onBindViewHolder(), and do below changes with it.
Double w = list.get(viewHolder.getAdapterPosition()).getRating();
String k = Double.toString(w);
viewHolder.textRating.setText(k);
viewHolder.textRating.setVisibility(View.INVISIBLE);
viewHolder.something.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
viewHolder.textRating.setVisibility(View.VISIBLE);
}
});
To maintain the review state:
First create one booelan variable inside your model class and generate getter-setter for that.
i.e.
private boolean isReviewedVisible = false;
public boolean isReviewedVisible() {
return isReviewedVisible;
}
public void setIsReviewedVisible(boolean isVisible) {
this.isReviewedVisible = isVisible;
}
Than add below checks in onBindViewHolder() method.
if(movie.isReviewedVisible()){
viewHolder.textRating.setVisibility(View.VISIBLE);
} else {
viewHolder.textRating.setVisibility(View.INVISIBLE);
}
viewHolder.something.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
movie.setReviewedVisible(true);
viewHolder.textRating.setVisibility(View.VISIBLE);
}
});

Fragment listview last value is not disappear

I have listview All the values are delete and update properly but only the last value is not delete in the listview.
Added a full fragment code. Take a look
For example
If I have three values in the listview If I delete 1 and 2 its removing and listview refresh properly but the last one is not refreshed in the listview

you have to tell your ListView that something changed in it's former List by calling notifyDataSetChanged() method of your adapter
Also you should not create a new instance of ArrayList, but only clear the old instance. Don't forget to check for null before clearing.

try calling the adapter again with a null like.
setListAdapter()

Android - Creating Listview using Custom Adapter Programmatically

I'm in learning about add view programmatically. But, I'm in confusing now.
I have data, there are idpatient, idheader. Patient can have more than one ID header. When I input idpatient, it will add listview (with custom adapter) programmatically. The number of listview is same with the number of ID header.
I want to set in each listview with data patient group by ID header..
So far, I add search view when loop adding listview, but when I input one ID header to seacrh view, all of listview will view the same data according to ID header in search view..
I'm sorry for the long explanation. Can anybody help me to solve this problem?
Thanks in advance

// 5. retrn rowView
return rowChildView;
}
}
Whene i click to the row of listview i get the "id" but how i can pass it to the popupMenu.
The solution: it just add settag(position) to imageview in getview, then :
public void showMenu(View v) {
PopupMenu popup = new PopupMenu(this, v);
popup.setOnMenuItemClickListener(this);
popup.inflate(R.menu.poupup_menu);
popup.show();
listView.performItemClick(v, (Integer) v.getTag(),listView.getItemIdAtPosition((Integer) v.getTag()));
}

You can use interface to communicate between them
In your adapter class, initialize
private OnItemSelectedListener mListener;
and add these methods
public void setOnItemClickLister(OnItemSelectedListener mListener) {
this.mListener = mListener;
}
//Creating an interface
public interface OnItemSelectedListener {
public void onItemSelected(String s);
}
in onClick function in adapter
use this
mListener.onItemSelected(id);
//id is your string
you can call it in MainActivity,
adapter.setOnItemClickLister(new OnItemSelectedListener() {
#Override
public void onItemSelected(String s) {
//you will get the string here, you can pass it as an argument in popup menu
}
});

On the adapter Side:
view.findViewById(R.id.menu_btn).setTag(id);
On the ListActivity Side:
public void showPopUp(View v){
currentId = v.getTag().toString();
PopupMenu popupMenu=new PopupMenu(this,v);
popupMenu.setOnMenuItemClickListener(ListActivity.this);
MenuInflater inflater=popupMenu.getMenuInflater();
inflater.inflate(R.menu.my_pop_up,popupMenu.getMenu());
popupMenu.show();
}
On XML side:
<ImageButton android:id="#+id/menu_btn"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:background="#drawable/ic_overflow"
android:layout_marginStart="10dp"
android:layout_marginEnd="20dp"
android:layout_alignParentEnd="true"
android:layout_centerVertical="true"
android:onClick="showPopUp"/>
Note: onClick="showPopUp" is very critical here.
This should be helpful. Thank you.

I'm not allowed to flag at this moment, but this might be a duplicate of how can i use the number from textfield of each row in listview and make a call on this number?
Anyway, my answer given there might solve your problem:
Here is what I do:
private class MyAdapter extends BaseAdapter {
private ListView listView;
...
#Override
public View getView(int i, View view, ViewGroup viewGroup) {
this.listView = (ListView) viewGroup;
and then in each View.OnClickListener I can get the position of the clicked item by
#Override
public void onClick(View view) {
...
MyAdapter.this.listView.getPositionForView((View) view.getParent()));
