Question

이 튜토리얼 http://www.sarahghaffary.com/android-quotes-generator-sample-application-using-alarmmanager-and-sqlite-database/을 따르고 있습니다.하지만 따옴표가 없어도 따옴표를 반복하여 계속 작성하는 방법을 알고 싶습니다. 아래의 코드를 변경해야하지만 확실하지는 않습니다. 초보자 만이 도움이 될 것입니다!

코드 :

public String getRandomQuote(){ 
SQLiteDatabase db = this.getWritableDatabase(); 
String selectQuery = "SELECT * FROM " + QUOTES_TABLE_NAME + " WHERE " + KEY_ISREAD + " = 0 ORDER BY RANDOM() LIMIT 1"; 
Cursor cursor = db.rawQuery(selectQuery, null); 

if (cursor != null) 
    if(cursor.moveToFirst()){ 
     db.execSQL("update " + QUOTES_TABLE_NAME + " set " + KEY_ISREAD + " = 1 where "+ KEY_ID +" = "+ cursor.getString(0)); 
     return cursor.getString(1); 
    } 
return "Sorry, you ran out of quotes <img src="http://www.sarahghaffary.com/wp-includes/images/smilies/icon_biggrin.gif" alt=":D" class="wp-smiley"> "; 
}

public String getRandomQuote(){ 
SQLiteDatabase db = this.getWritableDatabase(); 
String selectQuery = "SELECT * FROM " + QUOTES_TABLE_NAME + " WHERE " + KEY_ISREAD + " = 0 ORDER BY RANDOM() LIMIT 1"; 
String UpdateAllQuery= "Update "+ QUOTES_TABLE_NAME + " set " + KEY_ISREAD + " = 0"; 
Cursor cursor = db.rawQuery(selectQuery, null); 
String quote = ""; 

if (cursor != null){ 
     cursor.moveToFirst(); 
     if (cursor.getCount() < 1){ 
      db.execSQL(UpdateAllQuery); 
      cursor = db.rawQuery(selectQuery, null); 
      cursor.moveToFirst(); 
     } 
     db.execSQL("update " + QUOTES_TABLE_NAME + " set " + KEY_ISREAD + " = 1 where "+ KEY_ID +" = "+ cursor.getString(0)); 
     quote = cursor.getString(1); 
     return quote; 
}else{ 
    return "Sorry, you ran out of quotes <img src="http://www.sarahghaffary.com/wp-includes/images/smilies/icon_biggrin.gif" alt=":D" class="wp-smiley"> ";
