本文实例讲述了Android编程实现仿心跳动画效果的方法。分享给大家供大家参考，具体如下：

// 按钮模拟心脏跳动 private void playHeartbeatAnimation() { AnimationSet animationSet = new AnimationSet(true); animationSet.addAnimation(new ScaleAnimation(1.0f, 1.8f, 1.0f, 1.8f, Animation.RELATIVE_TO_SELF, 0.5f, Animation.RELATIVE_TO_SELF, 0.5f)); animationSet.addAnimation(new AlphaAnimation(1.0f, 0.4f)); animationSet.setDuration(200); animationSet.setInterpolator(new AccelerateInterpolator()); animationSet.setFillAfter(true); animationSet.setAnimationListener(new AnimationListener() { @Override public void onAnimationStart(Animation animation) { } @Override public void onAnimationRepeat(Animation animation) { } @Override public void onAnimationEnd(Animation animation) { AnimationSet animationSet = new AnimationSet(true); animationSet.addAnimation(new ScaleAnimation(1.8f, 1.0f, 1.8f, 1.0f, Animation.RELATIVE_TO_SELF, 0.5f, Animation.RELATIVE_TO_SELF, 0.5f)); animationSet.addAnimation(new AlphaAnimation(0.4f, 1.0f)); animationSet.setDuration(600); animationSet.setInterpolator(new DecelerateInterpolator()); animationSet.setFillAfter(false); // 实现心跳的View imageView.startAnimation(animationSet); } }); // 实现心跳的View imageView.startAnimation(animationSet); }

由于这是一个循环的动画，所以需要开一个线程来进行动画的实现，当然还有另外一个方法，就是在一个动画结束开始另一个动画，在另一个动画结束开始这个动画也可以，这边示例用的是线程。

new Thread(){ public void run() { while (true){ try { Thread.sleep(1000); } catch (InterruptedException e) { // TODO Auto-generated catch block e.printStackTrace(); } runOnUiThread(new Runnable() { public void run() { playHeartbeatAnimation(); } }); } }; }.start();

希望本文所述对大家Android程序设计有所帮助。
