Actuellement, je travaille avec un projet pour afficher la valeur de la base de données dans une table sous Android verticalement.J'ai obtenu la réponse horizontalement, maintenant je le veux verticalement.Comment afficher les données de ma base de données SQL et afficher dans une table comme verticalement

que voulez-vous dire horizontalement? –
Désolé, j'en ai besoin verticalement comme la deuxième image. – Jincy
quelle est la différence entre deux? semble similaire. Pourquoi voulez-vous horizontal? il suffit d'obtenir des données et de faire la ligne d'élément listview avec l'orientation Linearlayout horizontale –
