Fragment makes it out of onCreateView whenever I switch out the layout, leading me to believe the problem is within the xml file itself
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout

the AddFragment.java:
public class AddFragment extends Fragment implements View.OnClickListener, DatePickerDialog.OnDateSetListener{
EditText activityName;
Spinner priority;
Button dateSelected;
TextView date;
View v;
Context context;
CallBackToMain backToMain;

String dateStrung = "";
public static AddFragment newInstance(Entrada e) {
Bundle args = new Bundle();

return fragment;
}
@Nullable
@Override
public View onCreateView(LayoutInflater inflater, @Nullable ViewGroup container, @Nullable Bundle savedInstanceState) {

return v;
}
@Override

this.context = context;

super.onActivityCreated(savedInstanceState);
instance();

}
private void config(){
if (modify != null){

date.setText(modify.returnDateInFormat());
String [] fullDateSplit = date.getText().toString().split("/");
dateStrung = fullDateSplit[2] + fullDateSplit[1] + fullDateSplit[0];
}
String[] values = {"Alta", "Media", "Baja"};
priority.setAdapter(new ArrayAdapter(context, android.R.layout.simple_list_item_1, values));
}
private void actions(){
actionButton.setOnClickListener(this);
}
@Override
public void onClick(View v) {
if (v.getId() == R.id.date_select){
new DatePickerDialog(context, AddFragment.this,
Calendar.getInstance().get(Calendar.getInstance().YEAR),

Calendar.getInstance().get(Calendar.getInstance().DAY_OF_MONTH)).show();
}
else if (v.getId() == R.id.save){

}
}
@Override
public void onDateSet(DatePicker view, int year, int month, int dayOfMonth) {
//Si no, 0 es enero, 1 es febrero, etc.
month++;
//
if(year < Calendar.YEAR || (year == Calendar.YEAR && month < Calendar.MONTH) || (year == Calendar.YEAR && month == Calendar.MONTH && dayOfMonth < Calendar.DAY_OF_MONTH)){
new AlertDialog.Builder(context).setTitle("Fecha invalida").setMessage("Fecha anterior al día presente").show();
}
else{
dateStrung = year + "" + month + "" + dayOfMonth;
date.setText(dayOfMonth + "/" + month + "/" + year);
}
}
public interface CallBackToMain{

}
}
It simply comes to a dead halt in:
v = inflater.inflate(R.layout.addfragment, container, false);
with the error java.lang.NullPointerException: Attempt to invoke virtual method 'boolean java.lang.String.equals(java.lang.Object)' on a null object reference
I've revised the java and the xml code countless times, but I can't seem to find the root cause of this, and to top it off it's a string.equals that seems to be the biggest culprit here, so I simply don't understand what could be happening...
Can anyone lend me a hand? I'm a bit of a rookie, it that hasn't been made clear yet ^^;
