Crear revelación circular para dispositivos pre-Lollipop(Android)

Question

¿Es posible obtener este nuevo Animator para dispositivos pre-Lollipop?

Soy novato y estoy tratando de obtener los archivos java de su documentation oficial, pero estoy realmente perdido, no sé cómo encontrarlo, etc.

Answer 1

¡Sí! puede usar la biblioteca CircularReveal : como dijo @Alejandro .

Pero debe modificar la dependencia de la biblioteca a:

dependencies {
compile ''com.github.ozodrukh:CircularReveal:1.1.1'' //without "@aar" contrary to what the documentation says
}

De lo contrario, obtendrás una excepción en algunos dispositivos que se ejecutan en la versión pre-lollipop.

Answer 2

Encuentro una biblioteca para ti. Circular reveal , es compatible con 2.3 dispositivos.

Espero que te ayude!

Answer 3

Espero que esto te ayude ... de lo contrario solo utiliza este http://pulse7.net/android/android-create-circular-reveal-animation-and-ripple-effect-like-whatsapp/

compile (''com.github.ozodrukh:CircularReveal:1.1.1@aar'') {
transitive = true;

Answer 4

Esta es una actualización de las respuestas de share y BadYous .

1. La mejor biblioteca sigue siendo Circular Reveal .
2. La descripción correcta es compile ''com.github.ozodrukh:CircularReveal:2.0.1''

3. Use la importación correcta para ViewAnimationUtils

   import io.codetail.animation.ViewAnimationUtils;

Answer 5

La mejor biblioteca es: CircularReveal

utilizar :

Use regularmente RevealFrameLayout & RevealLinearLayout

<io.codetail.widget.RevealFrameLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent">
<!-- Put more views here if you want, it''s stock frame layout -->
<android.support.v7.widget.CardView
...
/>
</io.codetail.widget.RevealFrameLayout>

y:

 View myView = findView(R.id.awesome_card);
// get the center for the clipping circle
int cx = (myView.getLeft() + myView.getRight()) / 2;
int cy = (myView.getTop() + myView.getBottom()) / 2;
// get the final radius for the clipping circle
int finalRadius = Math.max(myView.getWidth(), myView.getHeight());
SupportAnimator animator =
ViewAnimationUtils.createCircularReveal(myView, cx, cy, 0, finalRadius);
animator.setInterpolator(new AccelerateDecelerateInterpolator());
animator.setDuration(1500);
animator.start();

Esta biblioteca es simple y funciona muy bien en pre lollipop.

No podemos usar Animator para dispositivos pre Lollipop. Aquí está el Animator.java
