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

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);
}
});

Please help

i think that the position of category in popup menu will be the same as section value of the second recyclerView if you get the position of clicked item in your activity by listening on item's click you can scroll the recyclerView using the LayoutManager.
recyclerView.getLayoutManager().scrollToPosition(youPositionInTheAdapter).

Getting focus of EditText inside RecyclerView

I'm implementing an application in which user can store Debit Cards and later they can use it by just entering the CVV number of the same card. I have used RecyclerView for all the items(Debit Cards) stored by the user. Everything is working fine, view is rendering all good and I have used LinearLayoutManager to show Horizontal scroll.
Now the problem which I am facing is whenever I try to enter CVV of any card as soon as I click on it the view gets shifted towards the last item of the list of Stored Cards, So if I'm having three cards stored in my list and I try to enter CVV for the first one the view is shifting directly to the third card but the focus remains on the first cards EditText. I don't know what's going on with the same. I'm sharing some code part for the same.
Setting adapter and defining horizontal scroll :-
recyclerAdapter = new RecyclerStoredCardAdapter(mContext, storedCards);
LinearLayoutManager layoutManager
= new LinearLayoutManager(this, LinearLayoutManager.HORIZONTAL, false);
storedCardListRecycler.setLayoutManager(layoutManager);
storedCardListRecycler.setVisibility(View.VISIBLE);
storedCardListRecycler.setAdapter(recyclerAdapter);
Sharing the screenshots with this so it will get clear. Any help would be appreciable. Thanks.

I am giving you my whole class. why? Because it will give you more understanding that how I used it with ListView.
Test it and Let me know. :)
Note
This line of code is very important - getActivity().getWindow().setSoftInputMode(WindowManager.LayoutParams.SOFT_INPUT_MASK_ADJUST);

Not able to reproduce this issue. Let me know if the following code does what you are facing. If not, can provide more feedback if you share you Adapter's Code.
MainActivity.java
public class MainActivity
extends AppCompatActivity {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
RecyclerView recyclerView = (RecyclerView) findViewById(R.id.recycler_view);
MyAdapter adapter = new MyAdapter();
recyclerView.setLayoutManager(new LinearLayoutManager(this, LinearLayoutManager.HORIZONTAL, false));
recyclerView.setAdapter(adapter);
}
}
public class MyAdapter extends RecyclerView.Adapter<RecyclerView.ViewHolder> {
#Override
public RecyclerView.ViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
View view = LayoutInflater.from(parent.getContext()).inflate(R.layout.recycler_ite, parent);
return new MyViewHolder(view);
}
#Override
public void onBindViewHolder(RecyclerView.ViewHolder holder, int position) {
((EditText)((MyViewHolder)holder).mBinding.findViewById(R.id.editText)).setHint(position + " ");
}
#Override
public int getItemCount() {
return 100;
}
public class MyViewHolder extends RecyclerView.ViewHolder {
View mBinding;
public MyViewHolder(View binding) {
super(binding);
this.mBinding = binding;
}
}
}
The 2xml layouts:
<EditText
android:id="#+id/editText"
android:layout_height="200dp"
android:layout_width="300dp"/>
</android.support.v7.widget.CardView>
My main_activity.xml is as follows:
<RelativeLayout
android:layout_height="match_parent"
android:layout_width="match_parent"
xmlns:android="http://schemas.android.com/apk/res/android">
<android.support.v7.widget.RecyclerView
android:id="#+id/recycler_view"
android:layout_height="wrap_content"
android:layout_width="match_parent"/>
</RelativeLayout>
As you can see this is the simplest case. Let me know if I missed anything.

The content of the adapter has changed but ListView did not receive a notification. How can i notify the list?

This is my fragment where I create the listview. When the data changed the listview is not notify. How can I do this? I make the request in viewModel using volley. I receive the next error: java.lang.IllegalStateException: The content of the adapter has changed but ListView did not receive a notification. Make sure the content of your adapter is not modified from a background thread, but only from the UI thread. Make sure your adapter calls notifyDataSetChanged() when its content changes.

ListView not reloading after data delete

I have set the custom BaseAdapter in Activity as :
llNoContactMessage = (LinearLayout) findViewById(R.id.llNoContacts);
listAdapter = new ContactsListAdapter(this, contactsList);
lvContactList = (ListView) findViewById(R.id.lvContactList);
lvContactList.setAdapter(listAdapter);
lvContactList.setOnItemClickListener(null);
And there is my Adapter class:
public class ContactsListAdapter extends BaseAdapter {
private List<ContactsInfo> contactList;
private Context context;
public ContactsListAdapter(Context context, List<ContactsInfo> contactsList) {
this.context = context;
this.contactList = contactsList;
}
#Override
public View getView(int position, View convertView, ViewGroup parent) {
View view = convertView;
final ContactsInfo contactsInfo = contactList.get(position);
if(view == null) {
LayoutInflater inflater = (LayoutInflater) context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
view = inflater.inflate(R.layout.activity_contacts_item, parent, false);
ViewHolder vh = new ViewHolder();
vh.tvContactName = (TextView) view.findViewById(R.id.tvContactName);
vh.tvContactNumber = (TextView) view.findViewById(R.id.tvContactNumber);
vh.llRemoveContact = (LinearLayout) view.findViewById(R.id.llRemoveContact);
view.setTag(vh);
}
final ViewHolder holder = (ViewHolder) view.getTag();
holder.tvContactName.setText(contactsInfo.getContactName());
holder.tvContactNumber.setText(contactsInfo.getContactNumber());
holder.llRemoveContact.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
UIUtils.showRemoveContactAlert(context, contactsInfo);
if(UIUtils.contactRemoved) {
contactList.remove(contactsInfo);
setList(getContacts());
notifyDataSetChanged();
}
}
});
return view;
}
static class ViewHolder {
TextView tvContactNumber;
TextView tvContactName;
LinearLayout llRemoveContact;
}
#Override
public int getCount() {
return contactList.size();
}
#Override
public ContactsInfo getItem(int index) {
return contactList.get(index);
}
#Override
public long getItemId(int position) {
return getItem(position).get_id();
}
public void setList(List<ContactsInfo> list) {
contactList.clear();
contactList.addAll(list);
}
private List<ContactsInfo> getContacts() {
CrisisCallingDatabase crisisCallDB = new CrisisCallingDatabase(context);
return crisisCallDB.getContactsList();
}
}
The method to delete data from database is:
public static void showRemoveContactAlert(final Context context, final ContactsInfo contact) {
AlertDialog.Builder b = new AlertDialog.Builder(context);
b.setMessage("Remove Contact");
b.setCancelable(true);
b.setPositiveButton("Yes", new DialogInterface.OnClickListener() {
#Override
public void onClick(DialogInterface dialog, int which) {
CrisisCallingDatabase ccd = new CrisisCallingDatabase(context);
if(ccd.deletContact(contact.get_id())){
Toast.makeText(context, contact.getContactName() + " removed successfully.", Toast.LENGTH_SHORT).show();
contactRemoved = true;
} else {
Toast.makeText(context, "Remove contact failed.", Toast.LENGTH_SHORT).show();
contactRemoved = false;
}
CrisisCallingDatabase.closeDBConnections();
}
});
b.setNegativeButton("No", null);
b.show();
}
But the view of the list is not removing the item from the list. However after clicking the any UI component on the list again is reloading the list i.e. the deleted item is removed. I don't know where I did mistake. Any help will be appreciated.

Move your notifyDataSetChanged() call to the end of your setList method.

Finally solved the issue, I just moved the confirmation alert code inside the On Click event like below :
holder.llRemoveContact.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
context.runOnUiThread(new Runnable() {
#Override
public void run() {
AlertDialog.Builder b = new AlertDialog.Builder(context);
b.setMessage("Remove Contact");
b.setCancelable(true);
b.setPositiveButton("Yes", new DialogInterface.OnClickListener() {
#Override
public void onClick(DialogInterface dialog, int which) {
if(succefulRemoval)){
contactList.remove(contactsInfo);
setList();
Toast.makeText(context, contactsInfo.getContactName() + " removed successfully.", Toast.LENGTH_SHORT).show();
} else {
Toast.makeText(context, "Remove contact failed.", Toast.LENGTH_SHORT).show();
}
}
});
b.setNegativeButton("No", null);
b.show();
}
});
}
});

Maybe you got answer already, but just for an extra
public void setList(List<ContactsInfo> list) {
contactList.clear();
contactList.addAll(list);
contactList.notifyDataSetChanged();
}
