CircularTools
Circle based animations for Android (min. API 11)
Currently implemented:
- Circular reveal
- Circular transform
- Radial reaction
Reveal:YouTube | Transform:YouTube | Radial reaction:YouTube |
---|---|---|
Sample
Demo in the source and releases
Note
- it's a fork from https://github.com/ozodrukh/CircularReveal/
- independent from Jake Wharton's NineOldsAndroid
- the returned
animator
is anObjectAnimator
so you can reverse it.
Limitations
For reveal and transform:
- it will never use the native
ViewAnimationUtils.createCircularReveal
method - currently there is an issue: views with elevation cannot be animated correctly on Lollipop and above.
- workaround A: set the LayerType of the target (or source) view to LayerType.SOFTWARE
- workaround B: wrap your target or (source) view with a simple layout, without elevation, and animate that. Demo reveal uses this method.
- hardware acceleration cannot be used in every situation. See table below:
API 11-17 | API 18+ | |
---|---|---|
Reveal | Software | Hardware |
Transform | Software | Hardware |
For radial reaction
- only one reaction can be animated at the same time, in the same
RadialReactionParent
- only one layout implemented yet: a LinearLayout.
- once an affectedView is reached, it will be removed from the list in the
RadialReactionParent
. If you want to animate multiple times, you have to add the views again. See demo for details.
Usage
For reveal and transform you have to wrap your animated views with a CircularFrameLayout
.
<hu.aut.utillib.circular.widget.CircularFrameLayout
android:id="@+id/simple_reveal"
android:layout_width="match_parent"
android:layout_height="match_parent">
<!-- Put any child views here if you want, it's stock FrameLayout --> </hu.aut.utillib.circular.widget.CircularFrameLayout>
Transform:
//myTargetView & mySourceView are children in the CircularFrameLayout float finalRadius = CircularAnimationUtils.hypo(width, height);
//getCenter computes from 2 view: One is touched, and one will be animated, but you can use anything for center int[] center = CircularAnimationUtils.getCenter(fab, myTargetView);
animator = CircularAnimationUtils.createCircularTransform(myTargetView, mySourceView, center[0], center[1], 0F, finalRadius);
animator.setInterpolator(new AccelerateDecelerateInterpolator());
animator.setDuration(1500);
animator.start();
Reveal:
//myView is a child in the CircularFrameLayout float finalRadius = CircularAnimationUtils.hypo(width, height);
//getCenter computes from 2 view: One is touched, and one will be animated, but you can use anything for center int[] center = CircularAnimationUtils.getCenter(fab, myView);
animator = CircularAnimationUtils.createCircularReveal(myView, center[0], center[1], 0, finalRadius);
animator.setInterpolator(new AccelerateDecelerateInterpolator());
animator.setDuration(1500);
animator.start();
For radial reaction you have to wrap your views -that are affected by the radial reaction- with a RadialReactionParent
.
- Wrap your view
- Add a listener to it (this listener will be notified when the invisible circle reaches an affected view)
- Add views to the parent's watchlist by calling
addAffectedView(View v)
- Create animation and start it
- Get notified when the radial reaction's invisible circle reaches one of the affected view
<hu.aut.utillib.circular.widget.RadialReactionLinearLayout
android:id="@+id/reaction_parent"
android:layout_width="match_parent"
android:layout_height="match_parent">
<FrameLayout
android:id="@+id/child_1"
android:layout_width="80dp"
android:layout_height="80dp"
android:layout_alignParentTop="true"
android:layout_margin="10dp"
android:background="@color/material_deep_teal_500"
android:visibility="invisible" />
<!-- Put any child views here if you want, it's stock LinearLayout --> </hu.aut.utillib.circular.widget.RadialReactionLinearLayout>
Radial reaction:
reactionParent = (RadialReactionParent) view.findViewById(R.id.reaction_parent);
reactionParent.addListener(this);
//add views reactionParent.addAffectedView(child1);
ObjectAnimator animator = CircularAnimationUtils.createRadialReaction(reactionParent, fab, "action");
animator.setInterpolator(new AccelerateDecelerateInterpolator());
animator.setDuration(1500);
animator.start();
...
@Override
public void onRadialReaction(View affectedView, String action) {
//Do what you want with the view
}
How to add dependency
This library is not released in Maven Central, but instead you can use JitPack
add remote maven url
repositories {
maven {
url "https://jitpack.io"
}
}
then add a library dependency
dependencies {
compile 'com.github.AutSoft:CircularTools:1.1.0'
}
