SwipeRefreshLayout + ViewPager with Fragments not working

SwipeRefreshLayout + ViewPager with Fragments not working - android

I have implemented the SwipeRefreshLayout in many of the pages,and it working fine. but here i got stuck with one specific implementation , where i have a SwipeRefreshLayout for the ViewPager and ViewPager holding the FragmentPagerAdapter.
In my case , I have a ViewPager with two tabs and each holding the fragment with RecyclerView. On main page I have a SwipeRefreshLayout and on the onRefresh i need to load the API and update the fragments in ViewPager. Updating is working fine but unfortunately RecyclerView inside the Fragment ( ViewPager tab Item ) not scrolling top and it always calling the SwipeToRefresh.
I am familiar with using the SwipeRefreshLayout with RecyclerView, but here the problem is the main child of the SwipeRefreshLayout is ViewPager and it having the Fragment inside it and that fragment is holding the RecyclerView.
I have a thought of moving the SwipeRefreshLayout inside the fragments for the RecyclerView , but again here i have challenges like both the Fragments is having the same API. So that i am using the SwipeRefreshLayout directly on ViewPager to refresh my data.
Here is some of my codes.

similarly i have Favorites example as well. Mostly both will look like same, that's why not posting it here.
Sorry for posting the long question. Any help regarding this. Apologies for my poor English. Thanks in Advance.

How to place FrameView over Toolbar in Coordinator Layout

I want to place FrameView over Toolbar as show in the image below -

It's not the most elegant way but you could set the elevation on the different views to force which is on top. Also I believe within a frame layout the order in which you add the layout in your xml plays an important role in what is causing your problems

Full Screen DialogFragment is not visible after starting from another DialogFragment

I have 3 DialogFragments A, B and C. I am starting Fragment A from Activity using FragmentTransaction Like this:
FragmentA dialog = new FragmentA();
Bundle bundle = new Bundle();
bundle.putString("GameLevelType", "Puzzle");
dialog.setArguments(bundle);
FragmentTransaction transaction = ((AppCompatActivity) context).getSupportFragmentManager().beginTransaction();
transaction.setTransition(FragmentTransaction.TRANSIT_FRAGMENT_OPEN);
transaction.add(android.R.id.content, dialog).addToBackStack(null).commit();
Now I am starting Fragment B from inside the Adapter of the RecyclerView of Fragment A Like this:
class MyViewHolder extends RecyclerView.ViewHolder implements View.OnClickListener {
TextView levelName;
CardView gameCard;
public MyViewHolder(View itemView) {
super(itemView);
levelName = (TextView) itemView.findViewById(R.id.gameText);
gameCard = (CardView) itemView.findViewById(R.id.gameCard);
gameCard.setOnClickListener(this);
}
#Override
public void onClick(View view) {
Handler handler = new Handler();
handler.post(new Runnable() {
#Override
public void run() {
FragmentB fragment = new FragmentB();
FragmentTransaction gameTransaction = ((AppCompatActivity)context).getSupportFragmentManager().beginTransaction();
gameTransaction.setTransition(FragmentTransaction.TRANSIT_FRAGMENT_OPEN);
gameTransaction.add(android.R.id.content, fragment).addToBackStack(null).commit();
//fragment.show(((AppCompatActivity)context).getSupportFragmentManager(),"PuzzleDialog");
}
});
//((AppCompatActivity) context).getSupportFragmentManager().popBackStack();
}
}
Now I am starting Fragment C from Fragment B. But the Fragment C is not visible.
Here is Fragment C:

E/RecyclerView: No adapter attached; skipping layout. using ASYNC TASK

i've had a problem, when i've tried to view this below fragment showing "skipping layout". Can any one help me out how to solve this problem please.

Try setting the setting the RecyclerView with an empty Adapter before you execute your AsyncTask.
View rootView= inflater.inflate(R.layout.fragment_third, container, false);
recyclerView = (RecyclerView) rootView.findViewById(R.id.recyclerView);
-->recyclerView.setAdapter(new RecyclerViewAdapter(getActivity(), new ArrayList<>(), null);
new JSONTask().execute(url, this);
Then create a method in the RecyclerViewAapter to load the the populated List<JsonURLFullModel> from the AsyncTask's onPostExecute.
public void loadJson(List<JsonURLFullModel> jsonList){
mValues = jsonList;
notifyDataSetChanged();
}
If that doesn't work trying loading on the Ui thread from Asynctask using runOnUiThread
runOnUiThread(new Runnable() {
#Override
public void run() {
adapter.loadJson(...)
}
});
Edit 1 Adding loadJson to your RecyclerViewAapter.class
#Override
public int getItemCount() {
return mValues.size();
}
public void loadJson(List<JsonURLFullModel> jsonList){
mValues = jsonList;
notifyDataSetChanged();
}
//Below interface implimentation can be found in ThirdFragment
// you can write below interface separetly or in you can write in this class like below
public interface ItemListener {
void onItemClick(int mPosition, List<JsonURLFullModel> mValues);
}
Call the method in your PostExecute
#Override
protected void onPostExecute(ThirdFragModel result) {
super.onPostExecute(result);
//jsonfull.setText(result);
//dialog.dismiss(); // closing dialog, before the content load in ListView(i.e until application lodading it will run, then dialog closes)
getActivity().runOnUiThread(new Runnable() {
#Override
public void run() {
adapter.loadJson(result.getMovieModelList());
}
});
}
Also add your the Layout manager for the RecyclerView in onCreateView
View rootView= inflater.inflate(R.layout.fragment_third, container, false);
recyclerView = (RecyclerView) rootView.findViewById(R.id.recyclerView);
-->recyclerView.setAdapter(new RecyclerViewAdapter(getActivity(), new ArrayList<>(), null);
layoutManager = new AutoFitGridLayoutManager(getActivity(), 500);
recyclerView.setLayoutManager(layoutManager);

Fragments influence each other in Android ,how to prevent?

I'm using 1 Activity and 4 TabFragment in Android. When I add a keylistener in second TabFragment using EditText , My first TabFragment opens keyboard. I controlled that 2 xml_layout different each other.
So any idea why Fragments affect each other and how to prevent this ? . Did you anyone face that problem ?

Please help me in implementing searchview in viewpager .

With help of uploaded code
I can tell that
make method in your fragments named search and
call adapter filter method
public void search(String text)
{
adapter.filter(text)
}
you can check instance of fragment and call search method of fragment after this line
Fragment fragment = adapter.getFragment(viewPager.getCurrentItem());

I think the best design for this is to use the Activity as the central "hub" for events that need to go the fragments.
So this is how I would do this:
First start with a listener interface. This can be declared as an inner interface of the Activity:
static interface QueryListener {
void onQueryChange(String query);
}
Activity gets properties for holding listeners and methods for adding and removing listeners (declared synchronized to prevent those pesky ConcurrentModificationExceptions:
private List<QueryListener> mQueryListeners = new ArrayList<>();
public synchronized void addQueryListener(#NonNull QueryListener listener) {
// check if the listener was already added
// you could also use a Set instead of a List for this
if (mQueryListeners.contains(listener)) return;
mQueryListeners.add(listener);
}
public synchronized void removeQueryListener(#NonNull QueryListener listener) {
mQueryListeners.remove(listener);
}
Activity also gets a method that can be called by the fragment with the SearchView:
public synchronized void changeQuery(String query) {
for (QueryListener listener : mQueryListeners) {
listener.onQueryChange(query);
}
}
Now your fragments with the adapters need to implement QueryListener and register/unregister themselves:
Add this line somewhere in onCreate():
((YourActivity) getActivity()).addQueryListener(this);
Unregister in onDestroy():
#Override
public void onDestroy() {
((YourActivity) getActivity()).removeQueryListener(this);
super.onDestroy();
}
add the QueryListener method implementation:
#Override
public void onQueryChange(String query) {
// if (isVisible()) { if desired
mAdapter.filter(query);
}
Note: You don't have to have the fragment implement QueryListener; you can use an anonymous class. But you'll have to hold the reference to it so you can call removeQueryListener() with it later.
Now just hook up the SearchView:
#Override
public boolean onQueryTextChange(String query) {
((YourActivity) getActivity()).changeQuery(query);
}
Another pattern I've used is to create a dedicated class for registering/notifying listeners. I create a single instance of this class and have a method on the Activity to access it:
QueryHandler handler = ((YourActivity) getActivity()).getQueryHandler();
// QueryHandler has all the listener properties and methods shown for the Activity
...
handler.changeQuery(query);
Alternatively, you can also use one of the many open-source event bus packages like Otto to pass events amongst your fragments.
