问题 I require an animation for an image in my application. The image should start coming from the top left corner till the middle of screen. The image size will be smaller at the initial stage.

问题 I am using a RelativeLayout to put a rotating spinner animation on top of a placeholder image while the real image is being loaded in a background thread. When the real bitmap is ready, the code below is run with in the UI thread with Activity.runOnUiThread(Runnable) The problem is, that all my attempts to hide the rotating image after the real image was loaded seem to fail.

问题 I have a strange behaviour with the default layout animation in devices running Android 5 (Lollipop). I am using an activity with multiple Fragments which are replaced at runtime using the default fragment manager. When replacing the old fragment, i want to use an animation for a smooth ui flow.
