Я использую макет движения в своем проекте, и вот окончательный результат
it looks OK, but Animation plays with lag in some devices
- Animation plays with lag in old devices (Samsung j5 2016 & Samsung j5 2017 & HTC desire 820)
here is an old device record : видеофайл - Анимация отлично работает в эмуляторе и новых устройствах (Huawei p30 light и Samsung note 8)
в layout description
, scaleX
и scaleY
и alpha
меняются
вот мое описание макета исходный код

Есть Любая помощь сделать анимацию без лагов, пожалуйста? и снова здесь видеофайл , который задерживается при запуске анимации
