i'm trying put app uses prepopulated sqlite database when loaded, populate list view. i'm new android , have been using guides online me through. using examples site: http://www.reigndesign.com/blog/using-your-own-sqlite-database-in-android-applications/

i unsure how set start populating data list view. pointers or examples helpful.

public class databasehelper extends sqliteopenhelper{  //the android's default system path of application database. private static string db_path = "/data/data/com.example.testsqllite/databases/"; private static string db_name = "testdatabase"; private sqlitedatabase mydatabase;  private final context mycontext;   public databasehelper(context context) {      super(context, db_name, null, 1);     this.mycontext = context; }     public void createdatabase() throws ioexception{      boolean dbexist = checkdatabase();      if(dbexist){         //do nothing - database exist     }else{          //by calling method , empty database created default system path            //of application gonna able overwrite database our database.         this.getreadabledatabase();          try {              copydatabase();          } catch (ioexception e) {              throw new error("error copying database");          }     }  }  /**  * check if database exist avoid re-copying file each time open application.  * @return true if exists, false if doesn't  */ private boolean checkdatabase(){      sqlitedatabase checkdb = null;      try{         string mypath = db_path + db_name;         checkdb = sqlitedatabase.opendatabase(mypath, null, sqlitedatabase.open_readonly);      }catch(sqliteexception e){          //database does't exist yet.      }      if(checkdb != null){          checkdb.close();      }      return checkdb != null ? true : false; }  /**  * copies database local assets-folder created empty database in  * system folder, can accessed , handled.  * done transfering bytestream.  * */ private void copydatabase() throws ioexception{      //open local db input stream     inputstream myinput = mycontext.getassets().open(db_name);      // path created empty db     string outfilename = db_path + db_name;      //open empty db output stream     outputstream myoutput = new fileoutputstream(outfilename);      //transfer bytes inputfile outputfile     byte[] buffer = new byte[1024];     int length;     while ((length = myinput.read(buffer))>0){         myoutput.write(buffer, 0, length);     }      //close streams     myoutput.flush();     myoutput.close();     myinput.close();  }  public void opendatabase() throws sqlexception{      //open database     string mypath = db_path + db_name;     mydatabase = sqlitedatabase.opendatabase(mypath, null, sqlitedatabase.open_readonly); } @override public synchronized void close() {          if(mydatabase != null)             mydatabase.close();          super.close(); }  @override public void oncreate(sqlitedatabase db) {  }  @override public void onupgrade(sqlitedatabase db, int oldversion, int newversion) {  }      // add public helper methods access , content database.    // return cursors doing "return mydatabase.query(....)" it'd easy    // create adapters views. 

}

i think excellent tutorial on creating , using database class. have register, don't have verify don't have use real info.
