It can extend any kind of View to gain these features. This can reasonably be achieved in a single line statement in API 12 and above.ANDROID MATERIAL DESIGN CIRCULAR REVEAL ANIMATION
Below is an example where v is the view you wish to animate. This will slide the View in question off to the left by px. To slide the view back onto the UI we can simply do the following. If you only want to animate the height of a view from say 0 to a certain number you could implement your own animation:.
Try to use TranslateAnimation class, which creates the animation for position changes. Update: Here's the example for this. If you have the height of your view as 50 and in the hide mode you want to show only 10 px. The sample code would be. PS: There are lot's or other methods there to help you use the animation according to your need.
Also have a look at the RelativeLayout. LayoutParams if you want to completely customize the code, however using the TranslateAnimation is easier to use. This example code assumes you are putting your view in RelativeLayout, if not change the name of Layout, however other layout might not work.
How can I use this to circularly reveal an entire activity, without any shared elements? Specifically, I'd like my searchActivity to circularly reveal from the search action button in the toolbar. After looking for a solution for half a day without a result, I came up with an own implementation. I'm using a transparent activity with a matching root layout. The root layout is a view which can then be revealed with createCircularReveal. Every layout should work here.
This view will be revealed in the activity. It was important to put circularRevealActivity into a OnGlobalLayoutListenerbecause the view needs to be drawn for the animation.
The definition for R. However, it should work without that line too, if your design does not specify default transitions for activities. Let me know. To reverse the CircularReveal animation swap the startRadius and endRadius arguments. Also you will need to setup an AnimatorListener and in the onAnimationEnd callback method is where you can call finishAfterTransition. This is for when you press the up navigation or click on the back button. If you want to reverse the circular reveal on leaving activity, use the following modification to onBackPressed.

Is it working for you? I will give it a go this week. Working like a charm for me. I just had the feeling that this circular reveal should be possible without merging two activities into one If there are problems let me know.Android allows changing object properties over a certain time interval via the properties animation API.
The superclass of the animation API is the Animator class. The ObjectAnimator class can be used to modify attributes of an object. You can also add an AnimatorListener class to your Animator class. This listener is called in the different phases of the animation. You can use this listener to perform actions before or after a certain animation, e. The animate method on a View object returns an ViewPropertyAnimator object for the view.
It provides a fluent API to typical animations which can be performed on views. You can also register action, which are executed before the start or after the end of the animation. Via the setInterpolator method you register an TimeInterpolator object with an animation. It defines the rate of change for an animation. The standard is linear. The Android platform defines a few default ones. For example, the AccelerateDecelerateInterpolator class defines that the animation starts and ends slowly but accelerates through the middle.
The animation system cannot automatically understand every type. Via the setEvaluator method you can set an object of type TypeEvaluator. It allows creating animations for arbitrary types, by providing custom evaluators for these types. The LayoutTransition class allows setting animations on a layout container and a change on the view hierarchy of this container will be animated. Animations can be applied to Views but it is also possible to apply them on the transition between activities.
Create a new Android project with the top level package name com. If you run this example and press the different buttons, the animation should start. Via the toolbar, you can start your HitActivity. Android 5. If you define a shared part the old view with be animating into the position and size of the new view. To test this create a project with the top level package called com. Create two activity with two different layout, both containing a ImageView with the same android:transitionName property.
If you run your application and click on the image view, it is animated to the view with the same android:transitionName property, in our case the button. Free use of the software examples is granted under the terms of the Eclipse Public License 2. This tutorial describes how to use the animation API in Android. Android Animations 1. Using animations Android allows changing object properties over a certain time interval via the properties animation API.Hi, in my previous post we looked at the basic reveal effect which we applied to view.
Circular Reveal Animation In Android
Though it looks great and makes your app look fresh we still need a lot more to make a cool material look. Circular reveals are really awesome, but they are just a part of the whole thing. When clicked it goes to circle, then after a while it reveals to the whole screen and new activity starts. We can do it with Animated Vector Drawable or just with static drawable backgorund shape and animating view width.
Making this kind of shape is easy. Width by your choice. I use ValueAnimator class over int with duration of ms on each change of value I resize button width. That what it looks like. Final width is 56 dp in pixels and on each update we change buttons layout params and requestLayout to update layout. Then at the same time we fade out text taking the same ms.
When text is out we show up Progress Bar. I just wait for 2 seconds using postDelayed method of Handler class and show reveal animation. Now the coolest part, what we have in here is a smooth activity change and it looks awesome. After done loading I do three actions simultaneously: reveal button, fade out progress bar, start next activity.
Since it was a button I had elevation of 4 dp on it to cast a slight shadow. We need to get rid of it before revealing because it needs to look like round button and reveal view are one single. I set reveal duration to ms which found to be the best. Reveal starts from button position with its radius and ends 1.
The reason I add 20 more percent than just the max dimension is to give it an overwhelming look. I could start next activity when reveal animation is done, after ms. Just after ms since the start of it, when reveal animation takes ms. Alright, that was some of the Advanced Android Circular Reveal stuff where we animated views in a gooey style.As your app is used, new information will need to be shown on the screen while old information is removed.
Immediately switching what's shown can look jarring or users can easily miss the new content on the screen. Utilizing animations can slow down the changes and draw the user's eye with notion so the updates are more apparent.
There are three common animations to use when showing or hiding a view. You can use the circular reveal animation, a crossfade animation, or a cardflip animation. Crossfade animations also known as dissolve gradually fade out one View or ViewGroup while simultaneously fading in another.
This animation is useful for situations where you want to switch content or views in your app. The crossfade animation shown here uses ViewPropertyAnimatorwhich is available for Android 3.
First, you need to create the two views that you want to crossfade. The following example creates a progress indicator and a scrollable text view:. Here's an example using the layout from the previous code snippet as the activity content view:. Card flips animate between views of content by showing an animation that emulates a card flipping over.
The card flip animation shown here uses FragmentTransactionwhich is available for Android 3. In order to create the card flip animation, you need a total of four animators. Two animators for when the front of the card animates out and to the left and in and from the left. You also need two animators for when the back of the card animates in and from the right and out and to the right. Each side of the "card" is a separate layout that can contain any content you want, such as two text views, two images, or any combination of views to flip between.
You'll then use the two layouts in the fragments that you'll later animate. The following layouts create one side of a card that shows text:. And the other side of the card that displays an ImageView :. Create fragment classes for the front and back of the card.
These classes return the layouts that you created previously in the onCreateView method of each fragment.
You can then create instances of this fragment in the parent activity where you want to show the card. The following example shows nested fragment classes inside of the parent activity that uses them:. Now, you'll need to display the fragments inside of a parent activity.
To do this, first create the layout for your activity. The following example creates a FrameLayout that you can add fragments to at runtime:. In the activity code, set the content view to be the layout that you just created. It's also a good idea to show a default fragment when the activity is created, so the following example activity shows you how to display the front of the card by default:.
Now that you have the front of the card showing, you can show the back of the card with the flip animation at an appropriate time. Create a method to show the other side of the card that does the following things:. Reveal animations provide users visual continuity when you show or hide a group of UI elements.Fix issues listed on codacy.

Star 6. Circular Reveal effect implementation for Android.Reveal is a new animation introduced in Android L that animates the view's clipping boundaries. Reveal animations provide users visual continuity when you show or hide a group of UI elements. This animation is often times used in conjunction with a floating action button.
You want to call enterReveal after the enter transition of the activity has been completed. Update enterReveal method to remove this listener from the stop listening to this animation.
This is done to disable reveal animation when the activity ends. While exiting the activity after the reveal transition, you want to finish the activity after completing the exit reveal animation.
To enable exit reveal transition on press of ActionBar up button or back button, call exitReveal from onOptionsItemSelected and onBackPressed respectively. If you do the reveal animation directly on the view, it might look weird because the stroke part of the shape gets revealed as well.
To prevent this, you can embed the view inside a FrameLayout which has stroke border as a background.

By doing this, the animation reveals the view while the background part remains the same, so it looks like only color part is revealed. The reveal effect can be made to look more natural if it starts where the user tapped. Jump to Section. Edit Page Page History.
