Привет в приведенном ниже коде, я работаю с bottom navigation
, он содержит другую опцию в том, что одна вещь - учетная запись. Если щелкнуть на нижней вкладке учетной записи, вы хотите отобразить cardview
в recyclerviews
Но data
ничего не придет. Он отображается пустым.
, используя это ниже xml для отображения контента в listview
формате
account. xml:
