游标索引超出范围例外，Android数据库

我正在做一个android应用程序。我正试图在文本视图中查看数据库的行。在开始时，我想采取数据库的第一行。然后我使用陀螺仪来滑动屏幕上的报价。但是我得到这个错误。任何人都可以帮助我吗？非常感谢。游标索引超出范围例外，Android数据库

这是幻灯片类

这是数据库：

package com.example.prova1; 

/**This class is for the database that is used to store quotes*/

@Override

if(cursor.moveToFirst()){ 

    do{

    } while(cursor.moveToNext()); 

}

} 

public void getQuote(int id, String s1,String s2) { 
    SQLiteDatabase db = this.getReadableDatabase(); 

    Cursor cursor = db.query("quotelist", new String[] { "quoteId", 
      "textQuote", "textAuthor" }, "quoteId" + "=?", 
      new String[] { String.valueOf(id) }, null, null, null, null);

s2=cursor.getString(2); 


} 
public int getQuotesCount() { 
    String countQuery = "SELECT * FROM quotelist" ;

    Cursor cursor = db.rawQuery(countQuery, null); 
    cursor.close(); 

    // return count 
    return cursor.getCount(); 
}

该错误是翠鸟行：S1 = cursor.getString（1）;在DatabaseClass

并在行：quotedatabase.getQuote（id，s1，s2）;在ShowQuote类
