Tableau dynamique au lieu de statique lors de la création d'icônes et de texte ListView Android

Question

J'utilise ce code suivant qui crée un ListView avec du texte et une icône, mais le problème que j'ai, c'est que je veux que le tableau soit dynamique plutôt que statique ma liste est créée dynamiquement pas statistiquement. Mon but ultime est de récupérer des chaînes spécifiques de mon Db et de les afficher ensuite dans la Listview où chaque chaîne serait dans chaque rangée. Merci beaucoup d'avance.

Mon code source:

Answer 1

while (c.isAfterLast() == false) { 
     rawImage = c.getString(c.getColumnIndex("couponThumbnailResult")); 
     keyWord = c.getString(c.getColumnIndex("keyWordResult")); 
     histDesRes = c.getString(c.getColumnIndex("historyDescriptionResult")); 
     //Toast.makeText(getApplicationContext(), 
     //history, Toast.LENGTH_LONG).show(); 
     history = keyWord+" "+ histDesRes; 
     //Use an ArrayList to store your results from the DB 
     c.moveToNext(); 
    } 

String[] results = yourArrayList.toArray(); 

utiliser ce tableau dans votre adaptateur ....
