public class YellowFragment extends Fragment implements FlowerAdapter.FlowerClickListener{

mRestManager = new RestManager();

listCall.enqueue(new Callback<List<Flower>>() {
#Override

}

}
}
#Override

});
}
In this code, when i swipe, if mlat is None, there is swipe updating icon and it's not disappear.
What i wanted is that if mlat has some value, do getLinearPosts();, but if mlat has None, show Toast "Choose your location".
but refershing icon do not disappear
like this
Question: How can i disappear this updating or refreshing icon when mlat is None?
After your task is completed, just call swipeContainer_yellow.setRefreshing(false) and it will hide that progressbar
As i can see you have already used it, but problem is you are assuming that your response will be perfect all the time. So instead of keeping it inside if (response.isSuccessful()), keep it outside if condition and also put it in onFailure()
listCall.enqueue(new Callback<List<Flower>>() {
#Override
public void onResponse(Call<List<Flower>> call, Response<List<Flower>> response) {
swipeContainer_yellow.setRefreshing(false);
if (response.isSuccessful()) {
mFlowerAdapter.clear();
List<Flower> flowerList = response.body();
for(int i =0; i<flowerList.size(); i++) {
Flower flower = flowerList.get(i);
mFlowerAdapter.addFlower(flower);
}
}
}
#Override
public void onFailure(Call<List<Flower>> call, Throwable t) {
swipeContainer_yellow.setRefreshing(false);
}
});

This is my example where I am tapping on the map to get the tapped point coordinates and to send a search request to know more details about that place, for example, city, street. But the response is always null values.

}
**Response is always null values. What I do wrong?
This is a GitHub whole project for this example https://github.com/davmehrabyan/YandexMapSearch **
I tried to build an app that have 5 fragment that displayed using bottom navigation view. I use volley to get the data from database. i have a problem with calling the data. at fragment A. i call the web service and got some data and then display it using recyclerview. But if i move to another fragment ( lets say fragment B) and went back to the fragment A. the data is lost and it just show the standard ui like search widget,spinner widget. All i want to ask is :
where should i put the code to call web service for all my fragment. On the activity that handle the fragment or just on the fragment?
why volley doesn't call data again when i back to the fragment?
this is the code of my mainactivity that contain bottom navigation view with 5 fragments:
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
if(isNetworkStatusAvialable (getApplicationContext())) {
bottomNavigationView=(BottomNavigationView)findViewById(R.id.main_nav);
frameLayout=(FrameLayout) findViewById(R.id.main_frame);
herbal= new herbal();
crude = new crude();
database=new database();
analysis=new analysis();
compound=new compound();
setFragment(herbal);
bottomNavigationView.setOnNavigationItemSelectedListener(new BottomNavigationView.OnNavigationItemSelectedListener() {
#Override

{

I have trouble with runOnUiThread in socket io. I use this library. I have listener for some event. If I get this event I change the image. But when I get event image stay as before and I don't understand why it's happen. Maybe someone help or explain me what I'm doing wrong. Thanks in advance. This is my code
private void online(){
SocketService.getSocket().on("online", new Emitter.Listener() {
#Override
public void call(Object... args) {
activity.runOnUiThread(new Runnable() {
#Override
public void run() {
Log.d("myLogs", "online");
onlineOffline.setImageResource(R.drawable.online);
callTo.setOnClickListener(ProfileList.this);
callToRegion.setOnClickListener(ProfileList.this);

EDIT!
Socket connected successfully and I can see message online/offline in the log. Also I debug code and don't show error. Full code

I have a simple weather app that uses fragments to display the current, hourly and daily weather. I have noticed that when I open a heavy app (game) and then I try to open the my app it crashes with the null pointer exception because a fragment (maybe all of the 3) is not attached to the fragment manager.
I have experienced this crash many times but with no luck finding a solution to the problem. I have including a if-else statement to check if the fragment is attached (see the log). Why might I be getting the NPE?
Here is my log:

super(context);
}
public void setTouchListener(OnTouchListener onTouchListener) {
this.onTouchListener = onTouchListener;
}
private OnTouchListener onTouchListener;
#Override
public boolean dispatchTouchEvent(MotionEvent event) {
switch (event.getAction()) {
case MotionEvent.ACTION_DOWN:
onTouchListener.onTouch();
break;
case MotionEvent.ACTION_UP:
