-

i trying create number of buttons on view programatically , need array, can add button object in nsmutablearray?

yes can see following code

// create buttons sliding menu. simplicity create 5 standard buttons. nsmutablearray  *buttonarray = [[nsmutablearray alloc] init];   for(nsinteger = 0; < [self.slidemenuarray count]; i++)  {      // rounded rect nice      uibutton *btn = [uibutton buttonwithtype:uibuttontypecustom];       nsstring *title=[slidemenuarray objectatindex:i];       [btn setframe:cgrectmake(0.0f, 4.0f, 90.0f, 20.0f)];      [btn settitle:[nsstring stringwithstring:title] forstate:uicontrolstatenormal];          [btn setbackgroundcolor:[uicolor clearcolor]];      [btn settitlecolor:[uicolor whitecolor] forstate:uicontrolstatenormal];      [[btn titlelabel] setfont:[uifont systemfontofsize:12]];       [btn addtarget:self action:@selector(buttonpressed:) forcontrolevents:uicontroleventtouchupinside];      uiimage *backgroundview;      if(i==0)      backgroundview= [uiimage imagenamed:@"btnclk.png"];      else      backgroundview= [uiimage imagenamed:@"btn.png"];          [btn setbackgroundimage:backgroundview forstate:uicontrolstatenormal];      [buttonarray addobject:btn];   }

you can retrieve added button objects this-

for(int = 0; < [buttonarray count]; i++)     {         uibutton *btn = [buttonarray objectatindex:i];          // move buttons position in x-demension (horizontal).         cgrect btnrect = btn.frame;         btnrect.origin.x = totalbuttonwidth;         [btn setframe:btnrect];      }

edit: so after comments below, revisted , realized hanging me up. imagine client list , client details activity started : public class clientsmainactivity extends fragmentactivity { @override public void oncreate(bundle savedinstancestate) { super.oncreate(savedinstancestate); //studiotabopenhelper db; setcontentview(r.layout.main_client_activity); } } so works great, starts main_client_activity (defined in layout below, , call activity when button on main screen clicked): intent intent = new intent(getactivity(), clientsmainactivity.class); startactivity(intent); easy issue is, clientsmainactivity not call oncreateview or anything, sets layout layout defines fragment, , listfragment. fine cause not trying pass clientsmainactivity , if have hypothetical activity like: sessionmainsactivity called when click on session edit of client, not calling sessionsmainactivity same way (starts activity sets alayout), want layout set defines...
