Recyclerview not scrolling to saved position after screen rotation

Recyclerview not scrolling to saved position after screen rotation - java

Hi I want to save Recylerview scroll position when screen rotates so that Recyclerview scrolls to that position before user sees screen.
I have tried every possible solution so far for similar questions but nothing is working. I am using GridLayoutManager with Recyclerview and displaying grid list of movies using JSON data.
Please have a look!!
MainActivity:
public class MainActivity extends AppCompatActivity implements
SharedPreferences.OnSharedPreferenceChangeListener {

#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
recyclerView = (RecyclerView) findViewById(R.id.recycler_view);
movieList = new ArrayList<>();
adapter = new MovieAdapter(this, movieList);
/*
if (getActivity().getResources().getConfiguration().orientation == Configuration.ORIENTATION_PORTRAIT) {
recyclerView.setLayoutManager(new GridLayoutManager(this, 2));
} else {
recyclerView.setLayoutManager(new GridLayoutManager(this, 4));
}
*/
recyclerView.setLayoutManager(new GridLayoutManager(this, 2));
recyclerView.setAdapter(adapter);
checkSort();
}
#Override
protected void onSaveInstanceState(Bundle outState) {
super.onSaveInstanceState(outState);
outState.putParcelable(KEY_RECYCLER_STATE, recyclerView.getLayoutManager().onSaveInstanceState());
}
#Override

super.onRestoreInstanceState(savedInstanceState);
if(savedInstanceState != null)
{
Parcelable savedRecyclerLayoutState = savedInstanceState.getParcelable(KEY_RECYCLER_STATE);
recyclerView.getLayoutManager().onRestoreInstanceState(savedRecyclerLayoutState);

Is it possible to set ViewPager inside a fragment class?

I have a Fragment class and an Activity class which is related to that fragment, ViewPager has been initialized inside the Activity of MizActivity
My question is it possible to move ViewPager initialization from Activity class to the Fragment class So that I have better control?
Thanks in advance

Yes, a Viewpager can be setup in a Fragment.
You just need to get the right FragmentManager when constructing it i.e use getChildFragmentManager() in mViewPager.setAdapter(new TvShowEpisodeDetailsAdapter(getSupportFragmentManager()));
From https://developer.android.com/guide/fragments/fragmentmanager
Access the FragmentManager
Accessing in an activity
Every FragmentActivity and subclasses thereof, such as
AppCompatActivity, have access to the FragmentManager through the
getSupportFragmentManager() method.
Accessing in a Fragment
Fragments are also capable of hosting one or more child fragments.
Inside a fragment, you can get a reference to the FragmentManager that
manages the fragment's children through getChildFragmentManager().

If i'm reading this correctly, you have two tabs and a backend database that stores the to do items and their state? To get the second list to update, you just need to do the same thing that you're doing in your first list, and update the adapter's data set and notify that the data set changed. How you trigger this action in your second tab is really the question.
You can either use an interface and have your adapter notify your activity that recycler view 1 had an action on it, and you can then tell adapter 2 to update its data. You can either pass back the data and only notify one row, or you could notify the entire data set. If you're doing this all service based, you could just reload the recycler view from the service and it will have the new data.
I think all you need to figure out is how you want to notify tab 2 that it needs to update its data. My recommendation is:
public interface AdapterInterface
{
void itemCompleted(Item hereIsTheItemThatNeedsToBeAddedTo2);
}
Then inside your adapter have a property with getters/setters such as:
private AdapterInterface adapterInterfaceListener;
Inside your Fragment/Activity implement AdapterInterface and implement the itemCompleted function.
And then set your adapter.setAdapterInterfaceLisetener to that function that you implemented. Then inside your adapter when the user clicks the checkbook to mark it as done, you can call the adapterInterfaceListener.itemCompleted() function, and it will send that information to your Fragment/Activity. From there you can give that new data to adapter2, or recall the API, however you want to get the new data.
Does this help?

Material Dialog Error I am working on listview,

I want to show a Dialog Window inside an adapter but i get this error: Bad window token, you cannot show a dialog before an Activity is created or after it's hidden. This is MainActivity
public class Order extends AppCompatActivity {
