Lolipop öncesi cihazlar için dairesel görüntü oluşturma (Android)

Question

Lollipop öncesi cihazlar için bu yeni Animator'u almak mümkün mü?

Ben acemi ve ben onun resmi documentation den java dosyalarını almaya çalışıyorum, ama gerçekten kayıp, ben onu bulmak için nasıl bilmiyorum, vb Biz Lollipop öncesi Animator kullanamazsınız

Answer 1

olduğunu. Circular reveal, 2.3 cihazlarla uyumludur.

Umut sizin için yardımcı olur!

Answer 3

Evet! CircularReveal kütüphanesini kullanabilirsiniz: @Alejandro. , Önceden lolipop sürümü üzerinde çalışan bazı cihazlarda bir özel durum alırsınız Değilse

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

:

Ama yapmak kütüphane bağımlılığı değiştirmek zorunda.

Answer 4

iyi kütüphane: CircularReveal

kullanım:

Kullanım düzenli 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> 

ve:

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(); 

Bu kütüphane basit ve lolipop öncesi çok güzel çalışıyor. Bu size yardımcı olacaktır

Answer 5

Umut ... aksi takdirde sadece bu 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 6

Bu Alejandro's ve BadYous's answers için bir güncelleme kullanın.

1. En kütüphane hala Circular Reveal olduğunu.
2. sağ açıklama compile 'com.github.ozodrukh:CircularReveal:2.0.1'

3. ViewAnimationUtils

   import io.codetail.animation.ViewAnimationUtils;
