how send arraylist activity , display there ? want data activity , send activity , there printed. able pass single string not array of strings

code on java file,

main activity:

edittext et1 , et2 , et3 , et4 ; public final static string message_key = "com.example.prabhav.myapplication.message"; arraylist<string> ar , tr = new arraylist<string>();  @override protected void oncreate(bundle savedinstancestate) {     super.oncreate(savedinstancestate);     setcontentview(r.layout.activity_full_on); }  public void sm (view v) {     et1= (edittext) findviewbyid(r.id.name);     string msg1 = et1.gettext().tostring();     et2= (edittext) findviewbyid(r.id.dob);     string msg2 = et2.gettext().tostring();     et3= (edittext) findviewbyid(r.id.emailinput);     string msg3 = et3.gettext().tostring();     et4= (edittext) findviewbyid(r.id.clgi);     string msg4 = et4.gettext().tostring();     ar.add(msg1);     ar.add(msg2);     ar.add(msg3);     ar.add(msg4);     tr=ar;     intent intent = new intent(this,secact.class);     intent.putextra("myarray",tr);     startactivity(intent);  } 

another activity:

spinner s; public final static string message_key = "com.example.prabhav.myapplication.message";  @override protected void oncreate(bundle savedinstancestate) {     super.oncreate(savedinstancestate);     intent intent= getintent();     arraylist<string> ls = (arraylist<string>) getintent().getserializableextra("myarray");     arrayadapter<string> adptr=new arrayadapter<string>(this,android.r.layout.simple_list_item_1,ls);     s= (spinner) findviewbyid(r.id.sp);     s.setadapter(adptr);      //  setcontentview(r.layout.sec_lay);  } 

once try follows

mainactivity

intent = new intent(this,secact.class); i.putstringarraylistextra("myarray", tr); startactivity(i); 

2nd activity

arraylist<string> list=(arraylist<string>)getintent().getstringarraylistextra("myarray"); //use list wish 

hope helps you.
