Edit: As pointed out by Kiryl Tkach in the comments below, there is a better solution described in this Google I/O talk [this video] . You can create a custom transition that animates a TextView 's text size as follows: public class TextSizeTransition extends Transition { private static final String PROPNAME_TEXT_SIZE = "alexjlockwood:transition:textsize"; private static final String[] TRANSITION_PROPERTIES = { PROPNAME_TEXT_SIZE }; private static final Property<TextView, Float> TEXT_SIZE_PROPERTY = new Property<TextView, Float>(Float.class, "textSize") { @Override public Float get(TextView textView) { return textView.getTextSize(); } @Override public void set(TextView textView, Float textSizePix

This was covered in one of the Google I/O 2016 talks [this video] . The source for the transition which you can copy into your code is found here [LINK] . If your IDE complains the addTarget(TextView.class); requires API 21, just remove the constructor and add the target either dynamically or in your xml. i.e. (note this is in Kotlin) val textResizeTransition = TextResize().addTarget(view.findViewById(R.id.text_view))

Don't think that this code is correct because of the thrashing font cache. It is told here [this video] . This code will create a lot of cache with font size like 15.025 or 17.356, which will be never used in the future. The right way to do this is to swap text with drawable and after animation swap it back. Everything is told in this [this video] video.

I'm trying to run a shared element transition from a recycler view to a detail view containing a pager. Pretty much the same as in this blog post [LINK] . Everything works, except that the back-from-detail-to-overview animation is clipped to the overview recycler view cells. After watching this talk [this video] , I learned, that unless setSharedElementsUseOverlay is set to false on the activity's window, the transitions will run on an overlay that's on top of everything - the whole content of the activity if I understood correctly. So it should not be possible that the transition is hidden or clipped. I searched both for setSharedElementsUseOverlay and windowSharedElementsUseOverlay in my projec

I tried to make a transition between the two activities using a shared TextView as shown in Google I/O [this video] 2016, but it works strangely since the text doesn't seem to fit into some container and its edges get cut off when the animation plays, though nothing should interfere with its scaling. I was putting it in other containers and tried different combinations, but the result was exactly the same. That said, when I go back from the second activity to the first, everything works as it should. A class for scaling text, TextResize.java [LINK] , has also been added to the project and included in shared element transition set between two activities. How can I fix incorrect text scaling animat
