public class mainactivity extends listactivity { string key_id = "_id"; string key_hole = "hoyo"; string key_par = "par"; string key_handicap = "handicap"; string key_yards = "yardaje";  @override protected void oncreate(bundle savedinstancestate) {      super.oncreate(savedinstancestate);      setcontentview(r.layout.activity_main);      databasehelper mydbhelper = new databasehelper(this);      arraylist<hashmap<string, string>> menuitems = new    arraylist<hashmap<string, string>>();         try {            mydbhelper.createdatabase();        } catch (ioexception ioe) {            throw new error("unable create database");        }        try {            mydbhelper.opendatabase();        }catch(sqlexception sqle){            throw sqle;        }      cursor c = mydbhelper.getallcoursecontacts();       if(c.movetofirst())       {           do{                hashmap<string, string> map = new hashmap<string,    string>();               map.put(key_hole, c.getstring(1));               map.put(key_par, getstring(2));               map.put(key_handicap, getstring(3));               map.put(key_yards,getstring(4));             }while(c.movetonext());      }         mydbhelper.close();       listadapter adapter = new simpleadapter(this, menuitems,                  r.layout.list_item,                 new string[] { key_hole, key_par, key_handicap,  key_yards }, new int[] {                         r.id.hole, r.id.par, r.id.handicap,r.id.yards });           setlistadapter(adapter);     }     @override  public boolean oncreateoptionsmenu(menu menu) {       getmenuinflater().inflate(r.menu.main, menu);      return true;  }   } 

my activity xml:

<linearlayout xmlns:android="http://schemas.android.com/apk/res/android"      xmlns:tools="http://schemas.android.com/tools"      android:layout_width="match_parent"      android:layout_height="match_parent"      android:paddingbottom="@dimen/activity_vertical_margin"      android:paddingleft="@dimen/activity_horizontal_margin"      android:paddingright="@dimen/activity_horizontal_margin"      android:paddingtop="@dimen/activity_vertical_margin"      tools:context=".mainactivity" >      <listview          android:id="@id/android:list"          android:layout_width="match_parent"          android:layout_height="wrap_content"           android:drawselectorontop="false"/>    </linearlayout> 

and item_list xml

   <?xml version="1.0" encoding="utf-8"?>    <linearlayout xmlns:android="http://schemas.android.com/apk/res/android"        android:layout_width="match_parent"        android:layout_height="match_parent"        android:orientation="vertical" >  <textview      android:id="@+id/hole"     android:layout_width="wrap_content"     android:layout_height="wrap_content"     android:textsize = "40sp"/> <linearlayout     android:layout_width="wrap_content"     android:layout_height="wrap_content"     android:orientation="horizontal">     <textview          android:id="@+id/par"         android:layout_width="wrap_content"         android:layout_height="wrap_content"         android:textsize="20sp"/>     <textview         android:id="@+id/handicap"         android:layout_width="wrap_content"         android:layout_height="wrap_content"         android:textsize="20sp"/>     <textview         android:id="@+id/yards"         android:layout_width="wrap_content"         android:layout_height="wrap_content"         android:textsize="20sp"/>    </linearlayout>     </linearlayout> 

the problem here:

map.put(key_hole, c.getstring(1)); // correct map.put(key_par, getstring(2)); // incorrect! map.put(key_handicap, getstring(3)); // incorrect! map.put(key_yards,getstring(4)); // incorrect! 

you have getstring() instead of c.getstring() last three.
