Я сталкиваюсь с ошибкой при установке ограничения горизонтальной цепи с помощью ConstraintLayout
:
E/AndroidRuntime: FATAL EXCEPTION: main

Я в основном добавляю ограничение как:
set.createHorizontalChain(buttonA.id, ConstraintSet.LEFT, buttonC.id, ConstraintSet.RIGHT, arrayOf(buttonA.id, buttonB.id, buttonC.id).toIntArray(), arrayOf(0f, 0f).toFloatArray(), 0)
У меня более 2 виджетов, потому что я передаю buttonA
, buttonB
и buttonC
.
