я использую Glide для отображения изображений в Android studio, но как я могу реализовать Glide в своем listview?
Мне нужна помощь от кого-либо.. пожалуйста, уважайте мой вопрос..
Хорошо, моя проблема в том, что я хочу использовать Glide для моего listview, но я не знаю, как это сделать..
Пожалуйста, сконструируйте мой listviewadapter так, чтобы скольжение работало, дайте мне любое другое возможное решение для достижения моей цели..
Моя цель-я просто хочу отобразить изображение и текст в listview или gridview с Glide и JSON, результат JSON-это мой php-скрипт..
Вот мой код..
