问题 I have a horizontal recyclerView, When I first open the activity I want to make all the items in recyclerview scroll to the bottom (to the right in this case) and back to the top (to the left). Kinda like an animation. Scroll behavior should be visible to the user. I tried to do it like: Animation slideRight = AnimationUtils.loadAnimation(this, R.anim.slide_right); Animation slideLeft = AnimationUtils.loadAnimation(this, R.anim.slide_left); slideRight.setDuration(1000); slideLeft.setDuration

问题 I'm changing locale of my app programmatically using the following method. It works fine but when I start an already existing singleTask activity using Intent.FLAG_ACTIVITY_CLEAR_TOP flag. Then application loses the layout direction but translation is correct. For example, if application language is Arabic then all views direction is changed to English locale (left-to-right). What could be the reason? I'm calling following method in attachBaseContext of BaseActivity and Application class.
