android - Use text from EditText in activity1 on button in activity2 -

i want button in activity2 show text entered in edittext in activity1. first app using more 1 activity may trying pass things wrong. i've tried setting button text direct edittext value saving didn't work right. direction appreciated!

activity1

start_day called when button in activity1 pressed. sends app activity2.

public class addtasksactivity extends appcompatactivity {      public final static string taskone = "task 1 content";      @override     protected void oncreate(bundle savedinstancestate) {         super.oncreate(savedinstancestate);         setcontentview(r.layout.activity_add_tasks);     }      public void start_day(view view){         intent intent = new intent(this, daytasksactivity.class);         intent.putextra("taskone", taskone);         startactivity(intent);     } } 

activity2

currently button shows text activity1 "task 1 content." i'm doing right in passing things around can't seem working , haven't quite found yet.

public class daytasksactivity extends appcompatactivity {      @override     protected void oncreate(bundle savedinstancestate) {         super.oncreate(savedinstancestate);         setcontentview(r.layout.activity_day_tasks);          bundle bundle = getintent().getextras();         string taskone = bundle.getstring("taskone");          button buttontaskone = (button) findviewbyid(r.id.button_task_one);         buttontaskone.settext(taskone);     } } 

1. first give id views in layout files
2. then instantiate views in respective activity class
3. then text edit text , save in bundle , pass it
4. get value bundle in second activity
5. set value in button

activity1

public class addtasksactivity extends appcompatactivity {  private edittext myedittext;  @override protected void oncreate(bundle savedinstancestate) {     super.oncreate(savedinstancestate);     setcontentview(r.layout.activity_add_tasks);     myedittext = (edittext) findviewbyid(r.id.put_your_id_here_form_layout_file); }  public void start_day(view view){     intent intent = new intent(this, daytasksactivity.class);     intent.putextra("taskone", myedittext.gettext().tostring());     startactivity(intent);  } } 

activity2

public class addtasksactivity extends appcompatactivity {  private button buttontaskone;  @override protected void oncreate(bundle savedinstancestate) {     super.oncreate(savedinstancestate);     setcontentview(r.layout.activity_day_tasks);     buttontaskone = (button) findviewbyid(r.id.button_task_one);     bundle bundle = getintent().getextras();     string taskone = bundle.getstring("taskone");     if (taskone != null){         buttontaskone.settext(taskone);     }  } }
