Мы сталкиваемся с проблемой с textwatcherlistener, т. Е. С клавиатурой несколько раз.
Edittext inputtype - это число, но экран, показывающий 2 клавиатуры, т. Е. Число и значение по умолчанию.
мы используем expandlistview (с еще одной динамической информацией в расширенном просмотре), имеет одинредактировать текст.
Edittext с использованием textwatcher слушателя.В childview текстовый код написан.
пытался скрыть клавиатуру, но не работал.
