The pager returns the 1st object in the array list, and keeps returning the 1st object even if i swing left and right, did a lot of debugging, and for some reason when the pager get's to getItem(int position) it start's going crazy, it FINDS the corresponding object , then looks a the previous object(pos-1) then does some other weird things and returns the 1st obj in arrayList.
This method is called within the ViewHolder of RecyclerViewAdapter

I have a RecyclerView, it has items in it. I need each item to have its own Activity, that is, we have item1 by clicking on it, Activity1 opens, there is also item2 about clicking on it, Activity2 is opened. Can this be done somehow? If so, how? I managed to make it so that when I clicked, the same Fragment opened, and the text changes depending on which item was clicked. But it doesn't quite suit me.

The positon param inside onBindViewHolder() method tells you which item of your RecyclerView clicked.
Use this to control your program and in out of onBindViewHolder() method you can get your item position by getAdapterPosition().
holder.Card.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
switch (position) {
case 0: {
// Start first activity.
break;
}
case 1: {
// Start Second activity.
break;
}
}
}
});
I need a help. I am developing dynamic tabs with dynamic data in viewpager fragment's list. Somehow i got the dynamic tabs and hit API in placeholder fragment to get the recyclerview list.

I want to pass my total entity (Incidencia) who is created in One fragment and pass it to another fragment who will show a list of each entity added before. Both fragments are inside of one Activity. Im using recyclerview to list the entities and this entity implements parcelable.

This is the fragment who will add the entity

This is the fragment who will show the list of entities
public class ListaIncidenciasTroncalFragment extends Fragment {

Bundle args = getArguments();
Incidencia incidencia = args.getParcelable("incident");
mlistaIncidenciasTroncalAdapter.add(incidencia);

This is the recyclerview adapter

You put the parcelable here
IngresoIncidenciaTroncalFragment fragment = new IngresoIncidenciaTroncalFragment();
Bundle args = new Bundle();
args.putParcelable("incident", incidencia);
But within IngresoIncidenciaTroncalFragment, you never got them.
Also, be sure to check the nullability of the arguments.
Bundle args = getArguments();
if (args != null) {
Incidencia incidencia = args.getParcelable("incident");
} else {
Log.w("GetIncidencia", "Arguments expected, but missing");
}
Also, you are missing many fields from writeToParcel that are being read into Incidencia(Parcel in), the first of which do not match, and the rest are out of order.
If you want to pass data between Fragments, see
How to implement OnFragmentInteractionListener
Communicating with Other Fragments
If both fragments in one Activity you just can use FragmentManager#findFragmentByTag(String) or FragmentManager#findFragmentById(int id) to get other fragment instance and just call some public method on that fragment to set entity.
Note that you should use either some tag or some container id when adding this fragments in order to be able to get them.
Try the update the Fragment like this
public class IngresoIncidenciaTroncalFragment extends Fragment implements
FechaDialog.DatePickerDialogFragmentEvents,HoraDialog.TimePickerDialogFragmentEvents ,FechaLlegadaDialog.DateLlegadaPickerDialogFragmentEvents{
private TextView mDateDisplay;
private TextView mTimeDisplay;
private Button botonAgregaIncidencia;
Context context;
private OnButtonClickedListener mListener;
private Spinner spinnerFallas;
public interface OnButtonClickedListener {
void onButtonClicked(Incidencia incidencia);
}
#Override
public void onAttach(Context context) {
if (context instanceOf OnButtonClickedListener) {
mListener = (OnButtonClickedListener) context;
}
}
#Nullable
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
/**

I have a recyclerview with some data and I have a searchview, and filter is working just fine. But un-filtering not working. I can't get the whole data in the recyclerview after un-filter. No data is showing. I have to re-open the activity to get data. I tried to used two data sets. But i have no idea where to use them.

Just Modify your function and Add check for null or "" .
it will work fine

I wish to set the titlebar in this fragment's activity to the HelpItem's description field.
On line 10, I set the title of the activity with a String representing a HelpItem's description.
Instead of getting the description of the retrieved HelpItem on line 9 I get the description of the next HelpItem.
I.E. in an ArrayList of five HelpItem objects with the helpDescriptions "aaa", "bbb", "ccc", "ddd", "eee" clicking on "bbb" in the
list displays "bbb" and the information text associated with it. The title is set to "ccc".
On line 19 the same call to helpItem.getHelpDescription() returns the description field of the "bbb" object.
When moving through the list via a ViewPager the next object in the list has the same issue until I reach the end of the list,
where the correct helpDescription field is displayed. I can also move back to the start of the list and it will display the correct
helpDescription, but this is then lost when I move forward and backward through the list again.
Any ideas why this is happening? Thanks.
