Listview не сохраняет элементы при повороте экрана - Android Studio

Question

ОК. У меня есть новостная программа, которая получает данные через JSON. Он имеет специальный адаптер, который включает в себя в основном строки и изображения. В верхней части экрана есть кнопка поиска и editText для критериев поиска. Это еще не работает, но будет легко исправлено позже. В любом случае все работает нормально, но когда я поворачиваю экран, данные исчезают, и вам нужно снова нажать кнопку поиска. Но тогда действительно это никогда не перезагружает данные. Я надеюсь, что это что-то в основной деятельности, поэтому я включил это здесь. Любая помощь будет оценена!
