This is my source:

                  Cursor curser=myDB.rawQuery("select * from "+TABLE_NAME+"",null); 
 if(curser.moveToFirst())
     {
      int k=0;
      System.out.println("enter first");
      do
        {
      System.out.println("enter second");
      if(status1==true)
      {
      System.out.println("enter third"); 
      for(int i=0;i<items.length;i++)
       {
      System.out.println("item"+items.length);
      System.out.println("enter fourth");
      Cursor dbcur = myDB.rawQuery("select * from "+TABLE_NAME+" where Status='"+items[i]+"'", null);
      System.out.println("enter fifth");
      int title=curser.getColumnIndex("Title");
      String tit=curser.getString(title);
      System.out.println("value"+tit);

     /* String title1=dbcur.getString(dbcur.getColumnIndex("Title"));
      System.out.println("title"+title1);
      String name1=dbcur.getString(dbcur.getColumnIndex("Name"));
      System.out.println("name"+name1);
      String open1=dbcur.getString(dbcur.getColumnIndex("Open"));
      System.out.println("open"+open1);
      String close1=dbcur.getString(dbcur.getColumnIndex("Close"));
      System.out.println("close"+close1);
      String no1=dbcur.getString(dbcur.getColumnIndex("No"));
      System.out.println("no"+no1);
      no.add(no1+","+k);
   first.put(no1+","+k, title1);
   second.put(no1+","+k,name1);
   third.put(no1+","+k, open1);
   fourth.put(no1+","+k,close1);
   k=k+1; 
   mylist=sorting(no,1,true);  */

     }

       }


        }while(curser.moveToNext());
     }
    curser.close();
  myDB.close();

           }
How to&Answers:

Either you do

if(cursor.moveToFirst() && cursor.getCount() >= 1){
  do{
    ....
        ....

}while(cursor.moveToNext());

OR you can do

if(cursor.getCount() >= 1){
  while(cursor.moveToNext()){
        ....
        ....

}

The cursor is position at index -1 intially

Answer:

What is your Cursor “curser” defined? Can you please post it

Edit:
As i can see, your second cursor dbcur isn’t placed to any position, so it is on his top position -1. Please try to place it with dbcur.moveToFirst() or dbcur.moveToNext()

Answer:

I am select only status value.so only one cursor is enough….Below code work correct……..

Correct code:

Cursor dbcur = myDB.rawQuery("select * from "+TABLE_NAME+" where Status='"+items[i]+"'", null);
                 if(dbcur.moveToFirst())
                  {
                      int k=0;
                      System.out.println("enter first");
                      do
                        {

                         String title1=dbcur.getString(dbcur.getColumnIndex("Title"));
                         System.out.println("title"+title1);
                         String name1=dbcur.getString(dbcur.getColumnIndex("Name"));
                         System.out.println("name"+name1);
                         String open1=dbcur.getString(dbcur.getColumnIndex("Open"));
                         System.out.println("open"+open1);
                         String close1=dbcur.getString(dbcur.getColumnIndex("Close"));
                         System.out.println("close"+close1);
                         String no1=dbcur.getString(dbcur.getColumnIndex("No"));
                         System.out.println("no"+no1);
                         no.add(no1+","+k);
                         first.put(no1+","+k, title1);
                         second.put(no1+","+k,name1);
                         third.put(no1+","+k, open1);
                         fourth.put(no1+","+k,close1);
                         k=k+1; 
                         mylist=sorting(no,1,true); 

                        }while(dbcur.moveToNext());
                  }
                     dbcur.close();
                     myDB.close();
