DiffUtil is an AppCompat utility class developed to ease Recyclerview updates. It is strongly advised to run all dataset operations in the main thread, to ensure consistency. And for now until next postDiffUtil calculations will also be run in the main thread for consistency concern. You can see we only have these 3 basic steps. The base DiffUtil. Callback implementation we use:. Now, with this diffResult, for every item insertion and deletion we get the precise adapter notification.
Typical application is list feeding, all new items are nicely inserted or removed which makes fancy animations to happen, like if we had set all the notifyItemInserted and notifyItemDeleted one by one. Until VLC 2.
Here is the DiffUtil. Callback specific to video grid which not only checks if items are the same, but if their content has changed also:. In our case this is two Item instances representing the same video file but artwork URL or time value has changed. We define here the updated value and return it. The dispatch util will call notifyItemChanged position, payload with this value. In the adapter, we override onBindViewHolder holder, position, payload to achieve this:. In our case, we load the thumb in the ImageView or we regenerate the progress string and update the progress bar with fillView.
The DiffUtil. Where detectMoves variable is a boolean which is set to true only in case of video resorting call, in other cases we spare the second pass.
Thanks to it, animations are fancier with only moving cards. We now master diffutil, but we can do better and get calculation out of UI thread. Rendez-vous to the second part of this post to check it out.

Leave a comment.Synchronized App Transitions is a feature in Android 9 that enhances the existing app transition architecture.
When a user opens, closes, or switches between apps, the SystemUI or Launcher homescreen process sends a request to control the animation frame-by-frame with guaranteed synchronization between view animations and window animations.
When the SystemUI or Launcher draws a new frame as part of an animation, it requests a different transform on the animating app surface that determines how the app is composed on the screen, and marks the request, a surface transaction, to be synchronized with the frame it's currently drawing.
This allows for new app transition animations that are not possible on Android 8. For example, the app launch animation can transform homescreen icons seamlessly into the app surface and the notification launch animation can transform notifications into the app surface.
For a reference implementation for the notification launch animation, see ActivityLaunchAnimator. To validate the performance of the animations, measure the performance of the controlling app, i.

I use these easy functions, it work like jquery slideUp slideDown, use it in an helper class, just pass your view :. Above method working but this is more realistic slide up and down animation from top of the screen. You can try this why. I had a similar requirement in the app I am working on. And, I found a third-party library which does a slide-up, slide-down and slide-right in Android.

ValueAnimator. ColorDrawable. Drawable. TransitionDrawable. ChangeBounds .The Navigation component lets you add both property and view animations to actions. To create your own animations, check out Animation resources.
Navigation also includes several default animations to get you started. To add animations to an action, do the following:. Once you've added animations, click the Text tab to toggle to the XML text view. In the following example, specifyAmountFragment is the source destination for the confirmationAction action:.
In addition to transition animations, Navigation supports adding shared element transitions between destinations. Shared element transitions are supplied programmatically rather than through your navigation XML file, as they require referencing the View instances that you wish to include in the shared element transition.
Each type of destination implements this programmatic API through a subclass of the Navigator. Extras interface. The Extras are passed to a call to navigate. The FragmentNavigator. Extras class allows you to attach shared elements to navigate calls to fragment destinations, as shown in the example below:. Activities rely on ActivityOptionsCompat to control Shared Element Transitions as detailed in the Start an activity with a shared element documentation and as shown in the example below:. When you navigate to or from an Activitypop animations are not applied automatically.
Instead, you must call ActivityNavigator. Content and code samples on this page are subject to the licenses described in the Content License.C636 huawei

However it does not provide me same result. Is there any better idea? Below animation gives a very reasonable immitation on my Galaxy Nexus. Obviously you can fine tune the parameters to your own liking. I created a very good approximation of iOS shaking when you long press a icon to remove app from homescreen.
You have to apply inside your code, programmatically, as it requires random number generation:. This code was design to be applied inside an adapter's gridview getViewbut you can apply to any view by changing the last line to:. First create an Animation resource file called shake. Click OK. If you would like to fine-tune the animation, simply modify the values in shake. IOS wobble animation is not that simple try to change pivot x and y randomly when rotate. You should change the value programatically though.
May be you also can use translate animation simultaneously. Example if you have onClick method and inside in it. You have animation like below it won't work. Other answers are correct as well but this is a bit smoother than them since it uses an interpolator produces smooth numbers for back an forth movement. Learn more. Asked 8 years, 1 month ago.
