java.lang.ClassCastException: android.view.ViewGroup $ LayoutParams нельзя отнести на android.widget.LinearLayout $ LayoutParams android 4.1.2

Question

У меня есть это исключение только на некоторых устройствах на android 4.1.2. Итак, я хочу знать, в чем проблема. Здесь не трассировки стека - ни одной строки из моего кода, только из SDK - исключение происходит в SDK, так что никаких линий не было пропущено:

Answer 1

В своем коде вы импортируете import android.widget.LinearLayout.LayoutParams вместо android.view.ViewGroup.LayoutParams;

так Удалить import android.widget.LinearLayout.LayoutParams;

и добавить import android.view.ViewGroup.LayoutParams;
