web services - Passing data from Activity to Fragment in android -


i have started android , working on simple login page,where user can use email , password login conditions while login. when user login "store owner",his name , email shown on next page (i.e on fragment class) working fine whenever user login "public user",his name , email not showing on next page.

note: using webservices , sharedpreferences fetch , save data.

thanks in advance

here code

loginactivity

frament class

public class myfragment extends fragment{

sharedpreferences sharedpreferenceslogin; public static final string my_prefs_names = "myprefsfiles"; textview names,emails;  string str_names,str_emails;  public myfragment() {     // required empty public constructor }   @override public view oncreateview(layoutinflater inflater, viewgroup container,                          bundle savedinstancestate) {      view layout = inflater.inflate(r.layout.fragment_my, container, false);       sharedpreferenceslogin=    getactivity().getsharedpreferences(my_prefs_names, context.mode_private);      names=(textview)layout.findviewbyid(r.id.names);     emails=(textview)layout.findviewbyid(r.id.emails);      str_names=     sharedpreferenceslogin.getstring("firstname","");     str_emails=      sharedpreferenceslogin.getstring("email","");      names.settext(str_names);     emails.settext(str_emails);  }

}

override newinstance() method in fragment this.

public static yourfragment newinstance(bundle bundle) {      activityfeedlistfragment fragment = new activityfeedlistfragment();     fragment.setarguments(bundle);     return fragment; }

and pass bundle object.

arrays - What causes a java.lang.ArrayIndexOutOfBoundsException and how do I prevent it? -

what arrayindexoutofboundsexception mean , how rid of it? here code sample triggers exception: string[] name = {"tom", "dick", "harry"}; for(int = 0; i<=name.length; i++) { system.out.print(name[i] +'\n'); } your first port of call should documentation explains reasonably clearly: thrown indicate array has been accessed illegal index. index either negative or greater or equal size of array. so example: int[] array = new int[5]; int boom = array[10]; // throws exception as how avoid it... um, don't that. careful array indexes. one problem people run thinking arrays 1-indexed, e.g. int[] array = new int[5]; // ... populate array here ... (int index = 1; index <= array.length; index++) { system.out.println(array[index]); } that miss out first element (index 0) , throw exception when index 5. valid indexes here 0-4 inclusive. correct, idiomatic for statement here be: for (int index = 0; index <...
