| Default Animations in Android |
Now don’t go running to build your app and see those fluid animations, unless you want to be disappointed and come back to this tutorial and continue it. Setting the animateLayoutChanges property is important, but you also need the following code to make it all work,
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.JELLY_BEAN) {
((ViewGroup) findViewById(R.id.llRoot)).getLayoutTransition()
.enableTransitionType(LayoutTransition.CHANGING);
}
We are now done, findViewById refrences the root layout inside which you want to show animations. Now is the time you can build and show or hide some views and test if this works or not! It will work. So wasn’t that easy? Of course you can have you custom animation and not the default changeBounds and Fade animations, but for simple Visibility the default ones are the best in my opinion.
In case you want to show your custom animations, you need to create a LayoutTransition object and supply it to the layout using the setLayoutTransition() method but that the code for some other day!
Also, if you are not interested in XML, you can also apply the same animations when there are layout changes using the beginDelayedTransition method. This method was added in API level 19 so make sure the device satisfies the API level before you use this code:
if (Build.VERSION.SDK_INT >= 19) {
TransitionManager.beginDelayedTransition((ViewGroup) yourViewOnWhichAnimationNeedsToBeShown.getParent());
}
This is it! Now your app will show animations on layout changes, show whenever the visibility of your views is set to Hidden or Visible, they are handled gracefully, 2 minutes of your time for better UI and UX. Let me what you think below. Cheers!
