Java 如何连续设置晶圆厂按钮(放大/缩小)的动画?
我想在Java 如何连续设置晶圆厂按钮(放大/缩小)的动画?,java,android,android-layout,android-animation,floating-action-button,Java,Android,Android Layout,Android Animation,Floating Action Button,我想在FloatingActionButton 我试过的 public void animFab() { ObjectAnimator scaleX = ObjectAnimator.ofFloat(fab, View.SCALE_X, from, to); ObjectAnimator scaleY = ObjectAnimator.ofFloat(fab, View.SCALE_Y, from, to); ObjectAnimator translationZ =
FloatingActionButton
我试过的
public void animFab() {
ObjectAnimator scaleX = ObjectAnimator.ofFloat(fab, View.SCALE_X, from, to);
ObjectAnimator scaleY = ObjectAnimator.ofFloat(fab, View.SCALE_Y, from, to);
ObjectAnimator translationZ = ObjectAnimator.ofFloat(fab, View.TRANSLATION_Z, from, to);
AnimatorSet set1 = new AnimatorSet();
set1.playTogether(scaleX, scaleY, translationZ);
set1.setDuration(500);
set1.setInterpolator(new AccelerateInterpolator());
set1.addListener(new AnimatorListenerAdapter() {
@Override
public void onAnimationEnd(Animator animation) {
}
});
ObjectAnimator scaleXBack = ObjectAnimator.ofFloat(fab, View.SCALE_X, to, from);
ObjectAnimator scaleYBack = ObjectAnimator.ofFloat(fab, View.SCALE_Y, to, from);
ObjectAnimator translationZBack = ObjectAnimator.ofFloat(fab, View.TRANSLATION_Z, to, from);
Path path = new Path();
path.moveTo(0.0f, 0.0f);
path.lineTo(0.5f, 1.3f);
path.lineTo(0.75f, 0.8f);
path.lineTo(1.0f, 1.0f);
PathInterpolator pathInterpolator = new PathInterpolator(path);
AnimatorSet set2 = new AnimatorSet();
set2.playTogether(scaleXBack, scaleYBack, translationZBack);
set2.setDuration(500);
set2.setInterpolator(pathInterpolator);
final AnimatorSet set = new AnimatorSet();
set.playSequentially(set1, set2);
set.addListener(new AnimatorListenerAdapter() {
@Override
public void onAnimationEnd(Animator animation) {
super.onAnimationEnd(animation);
set.start();
}
});
set.start();
}
问题
以上代码适用于Lolipop及以上设备,但不适用于KitKat设备
下面是我尝试过的一些链接
public void animFab() {
ObjectAnimator scaleX = ObjectAnimator.ofFloat(fab, View.SCALE_X, from, to);
ObjectAnimator scaleY = ObjectAnimator.ofFloat(fab, View.SCALE_Y, from, to);
ObjectAnimator translationZ = ObjectAnimator.ofFloat(fab, View.TRANSLATION_Z, from, to);
AnimatorSet set1 = new AnimatorSet();
set1.playTogether(scaleX, scaleY, translationZ);
set1.setDuration(500);
set1.setInterpolator(new AccelerateInterpolator());
set1.addListener(new AnimatorListenerAdapter() {
@Override
public void onAnimationEnd(Animator animation) {
}
});
ObjectAnimator scaleXBack = ObjectAnimator.ofFloat(fab, View.SCALE_X, to, from);
ObjectAnimator scaleYBack = ObjectAnimator.ofFloat(fab, View.SCALE_Y, to, from);
ObjectAnimator translationZBack = ObjectAnimator.ofFloat(fab, View.TRANSLATION_Z, to, from);
Path path = new Path();
path.moveTo(0.0f, 0.0f);
path.lineTo(0.5f, 1.3f);
path.lineTo(0.75f, 0.8f);
path.lineTo(1.0f, 1.0f);
PathInterpolator pathInterpolator = new PathInterpolator(path);
AnimatorSet set2 = new AnimatorSet();
set2.playTogether(scaleXBack, scaleYBack, translationZBack);
set2.setDuration(500);
set2.setInterpolator(pathInterpolator);
final AnimatorSet set = new AnimatorSet();
set.playSequentially(set1, set2);
set.addListener(new AnimatorListenerAdapter() {
@Override
public void onAnimationEnd(Animator animation) {
super.onAnimationEnd(animation);
set.start();
}
});
set.start();
}
ObjectAnimator translationZ = ObjectAnimator.ofFloat(fab, View.TRANSLATION_Z, from, to);
ObjectAnimator translationZBack = ObjectAnimator.ofFloat(fab, View.TRANSLATION_Z, to, from);
PathInterpolator pathInterpolator = new PathInterpolator(path);
正如您所知,这些特性是在API21中引入的,而早期的API不提供这些特性,这就是您看到这些错误的原因。但是,可以使用从支持库获取路径插值器
用于创建基于路径的[插值器]的帮助器(https://developer.android.com/reference/android/view/animation/Interpolator.html)
实例。在API 21或更新版本上,将使用平台实现,而在较旧的平台上,将使用兼容的替代实现
我不认为你需要一个“z”翻译的解决方案。(我真的看不出有和没有任何区别,但那可能只是我自己。无论如何,晶圆厂已经有了高度效果的阴影。)
这里是对animFab()
的一次重做,对其进行了一些修改,以适应21世纪之前的API。
确保您从v4支持库中挂起了PathInterpolatorCompat
。首先是一段视频,显示在API 19仿真器上工作的代码:
另一种可能是用于可绘制动画,但这将是一个完全重写。可能此库将帮助您了解“不在KitKat上工作”的实际含义吗?@azizbekian应用程序正在崩溃,因为
PathInterpolator
和ObjectAnimator.Offload(fab,View.translationz,to,from)
在api level 21Hey@Cheticamp中添加了它的工作,非常感谢您的解释,如果可能的话,您可以使用“AnimatedVectorDrawableCompat”小悟空提供任何示例代码吗?没问题。至于AnimatedVectorDrawableCompat
,我还没有使用过它,所以我没有任何示例代码可以共享。
