Transition between 2 recycler views having cards

I have 2 recycler views that have cards.They basically look the same have the same number of cards and everthing. The first one is for like viewing and other stuff and the second one is only for deleting cards. OnlongClicking a card in the first recycler view triggers the opening of the second recycler view. I wanted to add transitions in between them like what keep notes has done when a card is long clicked. Both the recycler view use the same adapter. I have set what the adapter should do based on passing context to the adapter. enter image description here this is my 1st layout having the 1st recycler view.enter image description here this is the 2nd layout having the second recycler view.I want like a seamless transition for the tool bar again just like what Google keeps has done.A simple solution would be preferred as I am very new to this stuff.
Here is the java code for the adapter.

I have added the code related to the scene transititon which is in the adapter.
here is a gif of the problem when i add a scene transition
enter image description here
As u can see there are 2 pauses when going from 1st to 2nd activity 1st pause being longer 2nd one shorter. And also a pause when exiting the 2nd activity which seems to have the same duration as the 2nd pause.

Why I cannot pass data from RecyclerView to another RecyclerView - AndroidX

I want to make data from RecyclerView1 Activity1 can be passed to RecyclerView2 Activity2

Add item on RecycleView Android

I'm trying to add an item on RecycleView like this:
I have an object called Image
public class Image{
public String name;
public String url;
}
When I click on the button to add a new item, my code is like this:
#Override
public void addItemOnList(String url) {
adapter.addItem(new ImageObject("aaaaaa", R.drawable.close_button));
}
That is my method which inserts on the list.
public void addItem(ImageObject imageObject) {
itemList.add(imageObject);
notifyDataSetChanged();
}
My problem is when I click for the first time in additem my onBindViewHolder doesn't iterate all the list but when I check in debug mod my getItemCount is correct! So If I try to add an item after the first time all work well.

New code:

}

onClickListener in RecyclerView.ViewHolder

I've got a RecyclerView.ViewHolder and RecyclerView.Adapter, I need after click on item and then send information about this item to another Activity.
PlacesAdapter.java
public class PlacesAdapter extends RecyclerView.Adapter<PlacesViewHolder> {
private PlacesActivity placesActivity;
Context context;
private int position;
List<Places> places;
public PlacesAdapter(List<Places> places) {
this.places = places;}
#Override
public void onAttachedToRecyclerView(RecyclerView recyclerView) {
super.onAttachedToRecyclerView(recyclerView);
}
#Override
public PlacesViewHolder onCreateViewHolder(ViewGroup viewGroup, int i) {
View v = LayoutInflater.from(viewGroup.getContext()).inflate(R.layout.places_view, viewGroup, false);
PlacesViewHolder pvh = new PlacesViewHolder(v);
return pvh;
}
#Override
public void onBindViewHolder(PlacesViewHolder personViewHolder, int i) {
personViewHolder.name.setText(places.get(i).name);
personViewHolder.address.setText(places.get(i).address);
Picasso.with(personViewHolder.itemView.getContext())
.load(places.get(i).photo)
.into(personViewHolder.getPhoto());
}
#Override
public int getItemCount() {
return places.size();
}
}
PlacesViewHolder.java
In this line "intent.putExtra(PlacesDetail.PLACES_NAME,);" How can I send name?
public class PlacesViewHolder extends RecyclerView.ViewHolder {
CardView cv;
public TextView name;
public TextView address;
public ImageView photo;
public PlacesViewHolder(final View itemView) {
super(itemView);
cv = (CardView)itemView.findViewById(R.id.cv);
name = (TextView)itemView.findViewById(R.id.person_name);
address = (TextView)itemView.findViewById(R.id.person_age);
photo = (ImageView)itemView.findViewById(R.id.person_photo);
itemView.setOnClickListener(new View.OnClickListener(){
#Override
public void onClick(View v) {
Context context = v.getContext();
Intent intent = new Intent(context, PlacesDetail.class);
intent.putExtra(PlacesDetail.PLACES_NAME,);
context.startActivity(intent);
}
});
}
public TextView getAddress() {
return address;
}
public TextView getName() {
return name;
}
public ImageView getPhoto() {
return photo;
}
}

This is the complete example of custom Adapter where i'm able to get the details of particular items. In MainActivity you need to set the adapter :
adapter = new MyAdapter(getApplicationContext(), account_no, title, aFN1, aLN1,aFN2, aLN2,aFN3, aLN3,isavilable,waitlist,flag);
adapter.notifyDataSetChanged();
mRecyclerView.setAdapter(adapter);
Now see the code for the custom Adapter :
public class MyAdapter extends RecyclerView.Adapter<MyAdapter.ViewHolder> {
String TAG = "MyAdapter";
Context context;
private String[] accountNo;
private String[] title;
private String[] afn1;
private String[] aln1;
private String[] afn2;
private String[] aln2;
private String[] afn3;
private String[] aln3;
private String[] isAvailable;
private String[] waitlist;
private int flag;
public static class ViewHolder extends RecyclerView.ViewHolder {
public TextView account_no,title,afn1,afn2,aln1,aln2,color,is_available;
private ImageView img_android;
CardView cardView;
public ViewHolder(CardView v) {
super(v);
account_no = (TextView)v.findViewById(R.id.acctno);
title = (TextView)v.findViewById(R.id.title);
afn1 = (TextView) v.findViewById(R.id.afn1);
cardView = v;
}
}
// Provide a suitable constructor (depends on the kind of dataset)
public MyAdapter(Context context, String[] accountNo,String[] title,String[] afn1,String[] aln1,String[] afn2,String[] aln2,String[] afn3,String[] aln3,String[] isAvailable, String[] waitlist,int flag) {
this.context = context;
this.accountNo = accountNo;
this.title = title;
this.afn1 = afn1;
this.aln1 = aln1;
this.afn2 = afn2;
this.aln2 = aln2;
this.afn3 = afn3;
this.aln3 = aln3;
this.isAvailable = isAvailable;
this.waitlist = waitlist;
this.flag = flag;
Log.d(TAG,afn1.toString() +aln1+afn2+aln2+afn3+aln3.toString()+waitlist);
}
#Override
public ViewHolder onCreateViewHolder(ViewGroup parent,int viewType) {
CardView cv = (CardView) LayoutInflater.from(parent.getContext()).inflate(R.layout.list_item, parent, false);
return new ViewHolder(cv);
}
#Override
public void onBindViewHolder(final ViewHolder holder, final int position) {
final CardView cardView = holder.cardView;
final TextView accountno = (TextView)cardView.findViewById(R.id.acctno);
accountno.setText(accountNo[position]);
final TextView titletxt = (TextView)cardView.findViewById(R.id.title);
titletxt.setText(title[position]);
final TextView afn1txt = (TextView) cardView.findViewById(R.id.afn1);
afn1txt.setText(afn1[position]+" "+aln1[position]);
Log.d(TAG,waitlist[position]);
cardView.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
int id = getItemViewType(position);
SharedPreferences sharedPreferences = context.getSharedPreferences(Constant.MYPREFERENCE,Context.MODE_PRIVATE);
SharedPreferences.Editor edit = sharedPreferences.edit();
edit.putString(Constant.ACCOUNT,accountNo[position]);
edit.putString(Constant.TITLE,title[position]);
edit.putString(Constant.AFN1,afn1[position]);
edit.putString(Constant.ALN1,aln1[position]);
edit.putString(Constant.AFN2,afn2[position]);
edit.putString(Constant.ALN2,aln2[position]);
edit.putString(Constant.AFN3,afn3[position]);
edit.putString(Constant.ALN3,aln3[position]);
edit.putBoolean(Constant.IS_AVAILABLE, Boolean.parseBoolean(isAvailable[position].toUpperCase()));
edit.putString(Constant.WAITLIST,waitlist[position]);
Log.d("WaitingNo2 :",""+String.valueOf(waitlist[position]));
edit.commit();
Intent intent = new Intent(v.getContext(), DetailsActivity.class);
v.getContext().startActivity(intent);
}
});
}
// Return the size of your dataset (invoked by the layout manager)
#Override
public int getItemCount() {
return accountNo.length;
}
}
After All that get the value from sharedPreferences in the Activity which is called on Card Click:
preferences = getSharedPreferences("myshared", Context.MODE_PRIVATE);
AccountNo = sharedPreferences.getString(Constant.ACCOUNT,null).toUpperCase();
title = sharedPreferences.getString(Constant.TITLE,null).toUpperCase();
afn1 = sharedPreferences.getString(Constant.AFN1,null).toUpperCase();
aln1 = sharedPreferences.getString(Constant.ALN1,null).toUpperCase();
afn2 = sharedPreferences.getString(Constant.AFN2,null).toUpperCase();
aln2 = sharedPreferences.getString(Constant.ALN2,null).toUpperCase();
afn3 = sharedPreferences.getString(Constant.AFN3,null).toUpperCase();
aln3 = sharedPreferences.getString(Constant.ALN3,null).toUpperCase();
isAvailable = sharedPreferences.getBoolean(Constant.IS_AVAILABLE,isAvailable);
waitlist = sharedPreferences.getString(Constant.WAITLIST,waitlist);
Now do whatever you want and enjoy the code.

You can achieve this by creating an interface inside your adapter for an itemclicklistener and then you can set onItemClickListener from your PlacesActivity.
Somewhere inside your PlacesAdapter you would need the following:
private onRecyclerViewItemClickListener mItemClickListener;
public void setOnItemClickListener(onRecyclerViewItemClickListener mItemClickListener) {
this.mItemClickListener = mItemClickListener;
}
public interface onRecyclerViewItemClickListener {
void onItemClickListener(View view, int position, String places_name);
}
Then inside your ViewHolder (which I've added as an inner class inside my adapter), you would apply the listener to the components you'd like the user to click, like so:
class PlacesViewHolder extends RecyclerView.ViewHolder implements View.OnClickListener {
PlacesViewHolder(View view) {
super(view);
view.setOnClickListener(this);
}
#Override
public void onClick(View v) {
if (mItemClickListener != null) {
mItemClickListener.onItemClickListener(v, getAdapterPosition(), PlacesDetail.PLACES_NAME);
}
}
}
This example shows an onClickListener being applied to the view inside PlacesViewHolder.
recyclerView.setAdapter(adapter);// set adapter on recyclerview
adapter.notifyDataSetChanged();// Notify the adapter
adapter.setOnItemClickListener(new PlacesAdapter.onRecyclerViewItemClickListener() {
#Override
public void onItemClickListener(View view, int position, String places_name) {
//perform click logic here (places_name is passed)
}
});
To implement this code, you would setOnItemClickListener to your adapter inside PlacesActivity as shown above.

try this , it's work with me correctly
Create a new class and this code
public class RecyclerItemClickListener implements RecyclerView.OnItemTouchListener {
private OnItemClickListener mListener;
public interface OnItemClickListener {
public void onItemClick(View view, int position);
public void onLongItemClick(View view, int position);
}
GestureDetector mGestureDetector;
public RecyclerItemClickListener(Context context, final RecyclerView recyclerView, OnItemClickListener listener) {
mListener = listener;
mGestureDetector = new GestureDetector(context, new GestureDetector.SimpleOnGestureListener() {
#Override
public boolean onSingleTapUp(MotionEvent e) {
return true;
}
#Override
public void onLongPress(MotionEvent e) {
View child = recyclerView.findChildViewUnder(e.getX(), e.getY());
if (child != null && mListener != null) {
mListener.onLongItemClick(child, recyclerView.getChildAdapterPosition(child));
}
}
});
}
#Override public boolean onInterceptTouchEvent(RecyclerView view, MotionEvent e) {
View childView = view.findChildViewUnder(e.getX(), e.getY());
if (childView != null && mListener != null && mGestureDetector.onTouchEvent(e)) {
mListener.onItemClick(childView, view.getChildAdapterPosition(childView));
return true;
}
return false;
}
#Override public void onTouchEvent(RecyclerView view, MotionEvent motionEvent) { }
#Override
public void onRequestDisallowInterceptTouchEvent (boolean disallowIntercept){}
}
And in your Activity add this to your adapter implementation
mRecyclerView.addOnItemTouchListener(
new RecyclerItemClickListener(getActivity(), mRecyclerView, new RecyclerItemClickListener.OnItemClickListener() {
#Override
public void onItemClick(View view, int position) {
// do something
}
}
}
#Override
public void onLongItemClick(View view, int position) {
// do whatever
}
})
);

RecyclerView on item click NullPointerException [duplicate]

This question already has answers here:
What is a NullPointerException, and how do I fix it?
(12 answers)
Closed 6 years ago.
So I've set up my RecyclerView with SQLite DB and it's populating the list, but every time I click on the list item it should open the new activity and pass data to it via intent extras.
The click gives me NullPointerException:

title = (TextView) itemView.findViewById(R.id.tekstNaListi);
container = itemView.findViewById(R.id.cont_item_root);
container.setOnClickListener(this);
}
#Override
public void onClick(View v) {
itemClickCallback.onItemClick(getAdapterPosition());
}
}
}
It gives the error on line itemClickCallback.onItemClick(getAdapterPosition()); which is the last line in the class.
I'm overriding onClick in the class where recycler view is populated like this:
#Override
public void onItemClick(int p) {
Todo item = (Todo) listData.get(p);
Intent i = new Intent(HomeScreen.this, Details.class);
Bundle extras = new Bundle();
extras.putString("naslov", item.getTitle());
extras.putString("datum", item.getRecordDate());
extras.putInt("id", item.getItemId());
startActivity(i);
}
That class implements implements RecAdapter.ItemClickCallback
Any ideas? Thanks!

EDIT:
This error shows up:
java.lang.NullPointerException: Attempt to invoke interface method 'void data.RecAdapter$ItemClickCallback.onItemClick(int)' on a null object reference
at data.RecAdapter$1.onClick(RecAdapter.java:67)
and it refeers to this line in adapter class:
itemClickCallback.onItemClick(position);

1) Check the callback null or not.
#Override
public void onClick(View v) {
if (itemClickCallback!=null){
itemClickCallback.onItemClick(getAdapterPosition());
}
}
2) The activity/class implements the method. This is okay. But, are you set the listener in your onCreate() ?
rectAdapter.setItemClickCallback(this);
3)EDITED Change your adapter like this:
public class RecAdapter extends RecyclerView.Adapter<RecAdapter.RecHolder> {
private int previousPosition = 0;
private List<Todo> listData;
private LayoutInflater inflater;
private ItemClickCallback itemClickCallback;
public interface ItemClickCallback {
void onItemClick(int p);
}
public void setItemClickCallback(final ItemClickCallback itemClickCallback) {
this.itemClickCallback = itemClickCallback;
}
public RecAdapter(List<Todo> listData, Context c) {
this.inflater = LayoutInflater.from(c);
this.listData = listData;
}
#Override
public RecHolder onCreateViewHolder(ViewGroup parent, int viewType) {
View view = inflater.inflate(R.layout.layout_row_za_listu, parent, false);
return new RecHolder(view);
}
#Override
public void onBindViewHolder(RecHolder holder, final int position) {
Todo item = listData.get(position);
holder.title.setText(item.getTitle());
if (position > previousPosition) {
AnimationUtil.animate(holder, true);
} else {
AnimationUtil.animate(holder, false);
}
previousPosition = position;
holder.container.setOnClickListener(new View.OnClickListener() {
#Override

itemClickCallback.onItemClick(position);
}
});
}
#Override
