I have only one fragment and I want to change this fragment in viewpager dynamically according to recycler view item data

my problem is same as link given below
I have a ViewPager by same fragments RecyclerView just load items in one fragment of ViewPager
but at this post no one solve issue...
I have a recycler view items...I want when I click on recycler view item it takes me to viewpager fragment and shows that data of clicked item dynamically and on swiping viewpager it should move previous and next fragment accordingly...under fragment I want to show data of recyclerrview item using single fragment...
I have done this by using multiple fragment and using multiple instances by different name and different layout name and different id for its recyclerView and it works but i have a large number of fragments and it is not the solution for me ):
here is my viewpager code
public class AndroidViewPagerExample extends FragmentActivity {
ViewPager pager;
int positionring;
String rgtv;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
requestWindowFeature(Window.FEATURE_NO_TITLE);
getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN,
WindowManager.LayoutParams.FLAG_FULLSCREEN);
setContentView(R.layout.mainuuuu);
Intent it = getIntent();
positionring = it.getIntExtra("POS", 0);
final int position = it.getIntExtra("POS", 0);
rgtv= it.getStringExtra("name");
pager = (ViewPager) findViewById(R.id.pager);
pager.setAdapter(new MyPagerAdapter(getSupportFragmentManager()));
pager.setPageTransformer(true, new RotateUpTransformer());
pager.setCurrentItem(position);
pager.addOnPageChangeListener(new ViewPager.OnPageChangeListener() {
Boolean first = true;
Boolean userScrollChange=false;
public void onPageScrollStateChanged(int state) {
System.out.println("onPageScrollStateChanged");
System.out.println("Current position=="+position);
int curreentpos=position;
int newpos=curreentpos+1;
int previousState=curreentpos-1;
if (previousState == pager.SCROLL_STATE_DRAGGING
&& state == pager.SCROLL_STATE_SETTLING)
userScrollChange = true;
else if (previousState == pager.SCROLL_STATE_SETTLING
&& state == pager.SCROLL_STATE_IDLE)
userScrollChange = false;
previousState = state;
}
public void onPageScrolled(int position, float positionOffset, int positionOffsetPixels) {
System.out.println("onPageScrolled");
}
public void onPageSelected(int position) {
// Check if this is the page you want.
System.out.println("onPageSelected");
Apples.newInstance(rgtv);
}
});
}
private class MyPagerAdapter extends FragmentPagerAdapter {
public MyPagerAdapter(FragmentManager fm) {
super(fm);
}
#Override

Firebase Recycler Adapter is not showing my Recyclerview in Fragments

Basically i followed the accepted answer of this with few changes in my Activity and it worked perfect. My problem is that I wrote the exact same codes for my Fragment. when I open my app, it doesn't show anything. Before I changed my code in my fragment from a custom Adapter to the FirebaseRecyclerAdapter, everything worked fine.
This is my Fragment class
public class HomeFragment extends BaseFragment {
public Button buttonsrch, openFreezer, openRef, openPantry, scrollToFreezer, scrollToRef, scrollToPantry;
public NestedScrollView scrollView;
public RelativeLayout mFreezerLayout,mRefrigeratorLayout, mPantryLayout;

}
#Override

#Override
public void onStop() {
super.onStop();
if (firebaseRecyclerAdapter != null){
firebaseRecyclerAdapter.startListening();
}
}
private void FocusToFreezer(){
scrollView.post(new Runnable() {
#Override
public void run() {
scrollView.smoothScrollTo(0, mFreezerLayout.getTop());
}
});
}
private void FocusToRef(){
scrollView.post(new Runnable() {
#Override
public void run() {
scrollView.smoothScrollTo(0, mRefrigeratorLayout.getTop());
}
});
}
private void FocusToPantry(){
scrollView.post(new Runnable() {
#Override
public void run() {
scrollView.smoothScrollTo(0, mPantryLayout.getTop());
}
});
}
}
The only difference I could find is OnStart() and onStop() in activity are protected while on fragments are public
EDIT I found another page with the same problem and apparently FirebaseRecyclerAdapter doesn't work well with Fragments

I finally found an answer
simply remove mFreezerRecyclerView.setHasFixedSize(true);

The problem is chatDialog.getUnreadMessageCount() giving me count 2 when I once enter in chat room and come back to my chat listing page.
Description on issue:-
Example:-
I have installed my application in two devices. when i send message from one (Device A) to other (Device B).The device B will display correct Unread count i.e 1 . Now when i click on chat dialog and get entered inside the chat room (of Device B). and come back to it's listing page and then again try to send message from Device A to device B . This time the unread count comes as 2 but it should be one as i already viewed my previous message. This get more worse if i try to open my chat room again to read the message(Device B) and get back to my listing page(Device B) after reading the message . This time if I send the message from Device A to Device B, Then the count came out as "5" just for my one message this thing is making me sick, I debugged the whole code, it's chatDialog .getUnreadMessageCount() who is returning me count "5", I don't know why my previous messages are not counted as being read messages and why everytime I open chat room one additional number gets added up inside the unread count.Please help me out , i am scratching my head from past two days.
Your help will be greatly Appreciated.
Thanks

Problem is that your AllDialogsMessageListener is not getting unregistered so unregister it by calling unregisterQbChatListeners(); when you will be opening your chat room screen . Every thing will work fine once you do that.
This what i mean :-
binding.listDialogsChats.setOnItemClickListener(new AdapterView.OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
QBChatDialog selectedDialog = (QBChatDialog) parent.getItemAtPosition(position);
if (currentActionMode == null) {
unregisterQbChatListeners();
ChatActivity.startForResult(((Activity) mContext), REQUEST_DIALOG_ID_FOR_UPDATE, selectedDialog);
} else {
dialogsAdapter.toggleSelection(selectedDialog);
}
}
});
private void unregisterQbChatListeners() {
if (incomingMessagesManager != null) {
incomingMessagesManager.removeDialogMessageListrener(allDialogsMessagesListener);
}
if (systemMessagesManager != null) {
systemMessagesManager.removeSystemMessageListener(systemMessagesListener);
}
dialogsManager.removeManagingDialogsCallbackListener(this);
}
cheers!!!

Please use this code below :
QBChatService.markMessagesAsRead("YOUR_DIALOG_ID", null, new QBEntityCallback<Void>() {
#Override
public void onSuccess(Void aVoid, Bundle bundle) {
QBRequestGetBuilder requestBuilder = new QBRequestGetBuilder();
requestBuilder.eq("_id", Team.getCurrent().getChatId());
QBChatService.getChatDialogs(null, requestBuilder, new QBEntityCallback<ArrayList<QBDialog>>() {
#Override
public void onSuccess(ArrayList<QBDialog> qbDialogs, Bundle bundle) {
if (qbDialogs != null && qbDialogs.size() > 0) {
QBDialog dialog = qbDialogs.get(0);//here you get your dialog with unreadMessageCount = 0
}
}
#Override
public void onError(QBResponseException e) {
}
});
}
#Override
public void onError(QBResponseException e) {
}
});

ViewPropertyAnimator loops unexpectedly

I'm trying to animate a set of buttons such that they disappear sequentually on click, then performs an action based on the button clicked. The action is assigned to the animation listener which triggers on animation end. This works fine.
The problem is that I want the buttons to reappear sequentually when the activity resumes. For some reason the action assigned to the animation listener re-triggers even after setting the animation to null. What am I missing?

Below is the menu builder. I have three menu items: Load database, price list, and about. This class manages all the animations.
public MenuItemBuilder(Context context) {
this.context = context;
init();
}
private void init() {
initLoadDatabase();
initPriceList();
initAbout();
}
private View getViewFromId(int res) {
return ((Activity) context).findViewById(res);
}
private ImageButton getImageButtonFromId(int res) {
return (ImageButton) ((Activity) context).findViewById(res);
}
private void initLoadDatabase() {
final ImageButton button = getImageButtonFromId(R.id.imageLoadDatabase);
button.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
animateAllViewsExit(ButtonType.LOAD_DATABASE);
}
});
}
private void initPriceList() {
final ImageButton button = getImageButtonFromId(R.id.imagePriceList);
button.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
animateAllViewsExit(ButtonType.PRICE_LIST);
}
});
}
private void initAbout() {
final ImageButton button = getImageButtonFromId(R.id.imageAbout);
button.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
animateAllViewsExit(ButtonType.ABOUT);
}
});
}
private List<View> getAnimatedViews() {
List<View> viewList = new ArrayList<>();
viewList.add(getViewFromId(R.id.imageLoadDatabase));
viewList.add(getViewFromId(R.id.priceListContainer));
viewList.add(getViewFromId(R.id.imageAbout));
return viewList;
}
public void animateAllViewsEnter() {
List<View> viewList = getAnimatedViews();
for (int i = 0; i < viewList.size(); i++) {
View view = viewList.get(i);
view.animate()
.setStartDelay((viewList.size() - i) * 250)
.alpha(1.0f);
}
}
private void animateAllViewsExit(ButtonType buttonType) {
List<View> viewList = getAnimatedViews();
for (int i = 0; i < viewList.size(); i++) {
View view = viewList.get(i);
ViewPropertyAnimator animator = view.animate()
.setStartDelay(i * 250)
.alpha(0.0f);
if (i == viewList.size() - 1) {
lastAnimation = animator;
}
}
setAnimationAction(buttonType);
}
private void setAnimationAction(final ButtonType buttonType) {
if (lastAnimation != null) {
lastAnimation.setListener(new Animator.AnimatorListener() {
#Override
public void onAnimationStart(Animator animation) {
}
#Override
public void onAnimationEnd(Animator animation) {
performAction(buttonType);
lastAnimation = null;
}
#Override
public void onAnimationCancel(Animator animation) {
}
#Override
public void onAnimationRepeat(Animator animation) {
}
});
}
}
private void performAction(ButtonType buttonType) {
switch (buttonType) {
case LOAD_DATABASE:
// TODO to be done
break;
case PRICE_LIST:
context.startActivity(new Intent(context, PriceList.class));
break;
case ABOUT:
context.startActivity(new Intent(context, About.class));
break;
}
}
private enum ButtonType {
LOAD_DATABASE,
PRICE_LIST,
ABOUT
}

Fixed it by setting the listener to both enter and exit animations.
public void animateAllViewsEnter() {
List<View> viewList = getAnimatedViews();
for (int i = 0; i < viewList.size(); i++) {
View view = viewList.get(i);
view.animate()
.setStartDelay((viewList.size() - i) * 250)
.alpha(1.0f)
.setListener(null);
}
}
private void animateAllViewsExit(ButtonType buttonType) {
List<View> viewList = getAnimatedViews();
for (int i = 0; i < viewList.size(); i++) {
viewList.get(i).animate()
.setStartDelay(i * 250)
.alpha(0.0f)
.setListener(getAnimatorListener(i == viewList.size() - 1, buttonType));
}
}
