android - Passing String Array to another class using Intents -

actually have 2 activities namely mainactivity , listview .
want pass string array "arr" mainactivity listview ..
, activity listview show list of elements of "arr"

note: data in arr supplied database created me , , works fine .

there issue retrieving of arr in activity listview

mainactivity

package com.vivekmishra1991.database;  import android.content.context; import android.content.intent; import android.database.cursor; import android.os.bundle; import android.app.activity; import android.view.menu; import android.view.view; import android.widget.arrayadapter; import android.widget.button; import android.widget.listview; import android.widget.textview;  public class mainactivity extends activity { public int i;  public string arr[] = new string[100];    private databasehelper databasehelper;  @override   protected void oncreate(bundle savedinstancestate) {     super.oncreate(savedinstancestate);     setcontentview(r.layout.activity_main);      // clickable textview       final textview textview=(textview) findviewbyid(r.id.savedcontent);    textview.setonclicklistener(new view.onclicklistener() {        public void onclick(view view) {               <--array(arr) retrived database-->              intent intent=new intent(mainactivity.this,listview.class);            intent.putextra("array",arr);           startactivity(intent);    }    });    }  // oncreate ends here    } 

listview

  <-imports->  public class listview extends activity { listview listview; intent intent=getintent(); string[] arr=intent.getstringarrayextra("array"); public void oncreate(bundle savedinstancestate) {     super.oncreate(savedinstancestate);     setcontentview(r.layout.view_list);       listview.findviewbyid(r.id.list);      arrayadapter<string> adapter = new arrayadapter<string>        (this,android.r.layout.simple_list_item_1,arr);     listview.setadapter(adapter); } 

}

you should getting extras in oncreate

'getintent().getstringarrayextra(string name)'

edit

i mistakenly wrote bundle method of passing object through intents. method wrote stores directly in intent.
