現在我正在使用sqllite所有存儲的JSON values.The值JSON應用程序被正確地存儲和我對下面的錯誤sqllite獲取數據時發生，請幫我...如何解決CursorIndexOutOfBoundsException

這是我的出處：

    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(); 

      }

你的光標「curser」是什麼定義的？你可以請張貼它

編輯：正如我所看到的，你的第二個光標dbcur沒有放置在任何位置，所以它在他的頂部位置-1。請嘗試使用dbcur.moveToFirst()或dbcur.moveToNext()

我已經加了我新的代碼......... – user533787 2010-12-09 09:48:30

我所看到的，你的第二個光標dbcur ISN」放置在任何位置，所以它處於最高位置-1。請嘗試將它與movetofirst（）或movetonext（）一起放置。 – Thrawn80 2010-12-09 09:53:47

我只選擇狀態value.so只有一個光標是不夠....下面的代碼工作正確放置........

正確的代碼：

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();

要麼你做

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

}while(cursor.moveToNext());

OR你可以做

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

}

光標是在指數-1 intially位置
