android - Link fragment button to another activity -

below edited code

@override public void onclick(view v) {     switch (v.getid()){          case r.id.btn_chg_password:             showdialog();             break;         case r.id.btn_order:             changemenu();             break;     } }  private void changemenu() {     sharedpreferences.editor editor = pref.edit();     editor.putboolean(constants.is_logged_in,false);     editor.putstring(constants.email,"");     editor.putstring(constants.name,"");     editor.putstring(constants.unique_id,"");     editor.apply();     order(); }  private void order(){      fragment login = new loginfragment();     fragmenttransaction ft = getfragmentmanager().begintransaction();     ft.replace(r.id.activity_activityresult1,activityresult1);     ft.commit(); 

i want change link activity_activityresult1 after press btn_order believe cannot link because fragment activity? on clicking btn_order want direct activity_activityresult1 <----- layout

below original code

 @override public void onclick(view v) {     switch (v.getid()){          case r.id.btn_chg_password:             showdialog();             break;         case r.id.btn_logout:             logout();             break;     } }  private void logout() {     sharedpreferences.editor editor = pref.edit();     editor.putboolean(constants.is_logged_in,false);     editor.putstring(constants.email,"");     editor.putstring(constants.name,"");     editor.putstring(constants.unique_id,"");     editor.apply();     gotologin(); }  private void gotologin(){      fragment login = new loginfragment();     fragmenttransaction ft = getfragmentmanager().begintransaction();     ft.replace(r.id.fragment_frame,login);     ft.commit(); } 

private void order(){   intent mintent = new intent();   mintent.setclassname(your_package_name_string, your_activity_name_string);   // ex: package name can "com.example"   // activity name "com.example.contact_developer"   startactivity(myintent);    or   intent myintent = new intent(getactivity(), targetactivity.class);  startactivity(myintent);  } 

use if mean navigate activity order button click of fragment hope helps.
