我设计了一个简单的布局。我已经完成了没有动画的设计,但现在我想在textview点击事件时添加动画,我不知道如何使用它。 我的xml设计看起来好不好? 任何建议将不胜感激。

你可以做两件事来添加动画,首先你可以让android动画布局改变你。这样每次你在布局中改变一些东西,如改变视图可见性或视图位置,android将自动创建淡入淡出/过渡动画。要使用该集
android:animateLayoutChanges="true"
在布局的根节点上。
您的第二个选择是手动添加动画。为此,我建议您使用Android 3.0(Honeycomb)中引入的新动画API。我可以举几个例子:
这会淡出View
:
view.animate().alpha(0.0f);
这使它逐渐消失:
view.animate().alpha(1.0f);
这会使View
向下移动高度:
view.animate().translationY(view.getHeight());
在将View
移动到其他位置之后,将view.animate().translationY(0);
返回到其起始位置:
setDuration()
您还可以使用View
设置动画的持续时间。例如,这会在2秒的时间内淡出view.animate().alpha(0.0f).setDuration(2000);
:
View
你可以根据需要组合任意数量的动画,例如这会淡出view.animate()
.translationY(view.getHeight())
.alpha(0.0f)
.setDuration(300);
并在0.3秒内同时向下移动:
AnimatorListenerAdapter
您还可以为动画分配侦听器并对各种事件做出反应。就像动画开始,结束或重复等一样。通过使用抽象类AnimatorListener
,您不必一次实现View
的所有回调,而只需要实现所需的回调。这使代码更具可读性。例如,以下代码淡出View.GONE
在0.3秒(300毫秒)的时间内将其向下移动高度,当动画完成时,其可见性设置为view.animate()
.translationY(view.getHeight())
.alpha(0.0f)
.setDuration(300)
.setListener(new AnimatorListenerAdapter() {
@Override
public void onAnimationEnd(Animator animation) {
super.onAnimationEnd(animation);
view.setVisibility(View.GONE);
}
});
。

请检查this链接。这将允许动画,如L2R,R2L,T2B,B2T动画。
此代码从左到右显示动画
TranslateAnimation animate = new TranslateAnimation(0,view.getWidth(),0,0);
animate.setDuration(500);
animate.setFillAfter(true);
view.startAnimation(animate);
view.setVisibility(View.GONE);
如果您想从R2L进行操作,请使用
TranslateAnimation animate = new TranslateAnimation(0,-view.getWidth(),0,0);
从上到下为
TranslateAnimation animate = new TranslateAnimation(0,0,0,view.getHeight());
反之亦然..
答案 2 :(得分:11)
基于@Xaver Kapeller的答案,我想出了一种在屏幕上出现新视图时创建滚动动画的方法(以及隐藏它们的动画)。
它来自这个州:
到
反之亦然。
因此,当用户点击第一个按钮时,元素“按钮1”,“按钮2”,“按钮3”和“按钮4”将使用淡入淡出动画显示,元素“最后一个按钮”将向下移动直到结束。布局的高度也会改变,允许正确使用滚动视图。
这是用动画显示元素的代码:
logging.disable(logging.DEBUG)
这是隐藏动画元素的代码:
private void showElements() {
// Precondition
if (areElementsVisible()) {
Log.w(TAG, "The view is already visible. Nothing to do here");
return;
}
// Animate the hidden linear layout as visible and set
// the alpha as 0.0. Otherwise the animation won't be shown
mHiddenLinearLayout.setVisibility(View.VISIBLE);
mHiddenLinearLayout.setAlpha(0.0f);
mHiddenLinearLayout
.animate()
.setDuration(ANIMATION_TRANSITION_TIME)
.alpha(1.0f)
.setListener(new AnimatorListenerAdapter() {
@Override
public void onAnimationEnd(Animator animation) {
super.onAnimationEnd(animation);
updateShowElementsButton();
mHiddenLinearLayout.animate().setListener(null);
}
})
;
mLastButton
.animate()
.setDuration(ANIMATION_TRANSITION_TIME)
.translationY(mHiddenLinearLayoutHeight);
// Update the high of all the elements relativeLayout
LayoutParams layoutParams = mAllElementsRelativeLayout.getLayoutParams();
// TODO: Add vertical margins
layoutParams.height = mLastButton.getHeight() + mHiddenLinearLayoutHeight;
}
注意隐藏动画的方法有一个简单的黑客攻击。在动画侦听器mHiddenLinearLayout上,我不得不使用以下方法删除侦听器:
private void hideElements() {
// Precondition
if (!areElementsVisible()) {
Log.w(TAG, "The view is already non-visible. Nothing to do here");
return;
}
// Animate the hidden linear layout as visible and set
mHiddenLinearLayout
.animate()
.setDuration(ANIMATION_TRANSITION_TIME)
.alpha(0.0f)
.setListener(new AnimatorListenerAdapter() {
@Override
public void onAnimationEnd(Animator animation) {
Log.v(TAG, "Animation ended. Set the view as gone");
super.onAnimationEnd(animation);
mHiddenLinearLayout.setVisibility(View.GONE);
// Hack: Remove the listener. So it won't be executed when
// any other animation on this view is executed
mHiddenLinearLayout.animate().setListener(null);
updateShowElementsButton();
}
})
;
mLastButton
.animate()
.setDuration(ANIMATION_TRANSITION_TIME)
.translationY(0);
// Update the high of all the elements relativeLayout
LayoutParams layoutParams = mAllElementsRelativeLayout.getLayoutParams();
// TODO: Add vertical margins
layoutParams.height = mLastButton.getHeight();
}
这是因为一旦动画侦听器附加到视图,下次在此视图中执行任何动画时,侦听器也将被执行。这可能是动画监听器中的错误。
项目的源代码在GitHub上: https://github.com/jiahaoliuliu/ViewsAnimated
快乐的编码!
更新:对于附加到视图的任何侦听器,应在动画结束后将其删除。这是通过使用
完成的mHiddenLinearLayout.animate().setListener(null);

尝试将此行添加到axml父级布局
android:animateLayoutChanges="true"
答案 4 :(得分:7)
基于@ashakirov 的回答,这是我使用淡入淡出动画显示/隐藏视图的扩展程序
fun View.fadeVisibility(visibility: Int, duration: Long = 400) {
val transition: Transition = Fade()
transition.duration = duration
transition.addTarget(this)
TransitionManager.beginDelayedTransition(this.parent as ViewGroup, transition)
this.visibility = visibility
}
使用示例
view.fadeVisibility(View.VISIBLE)
view.fadeVisibility(View.GONE, 2000)
答案 5 :(得分:5)
制作Visibility
更改动画的最简单方法是使用Transition API
,它在支持(androidx)软件包中提供。只需调用TransitionManager.beginDelayedTransition
方法,然后更改视图的可见性即可。有几种默认过渡,例如Fade
,Slide
。
private void toggle() {
Transition transition = new Fade();
transition.setDuration(600);
transition.addTarget(R.id.image);
TransitionManager.beginDelayedTransition(parent, transition);
image.setVisibility(show ? View.VISIBLE : View.GONE);
}
其中parent
是动画视图的父级ViewGroup
。结果:
这是Slide
转换的结果:
Transition transition = new Slide(Gravity.BOTTOM);
如果您需要不同的东西,编写自定义过渡很容易。这是我在another answer中写的CircularRevealTransition
的示例。它使用CircularReveal动画显示和隐藏视图。
Transition transition = new CircularRevealTransition();
android:animateLayoutChanges="true"
选项的作用相同,只是使用AutoTransition作为过渡。
答案 6 :(得分:4)
我能够以这种方式显示/隐藏菜单:
MenuView.java(扩展了FrameLayout)
private final int ANIMATION_DURATION = 500;
public void showMenu()
{
setVisibility(View.VISIBLE);
animate()
.alpha(1f)
.setDuration(ANIMATION_DURATION)
.setListener(null);
}
private void hideMenu()
{
animate()
.alpha(0f)
.setDuration(ANIMATION_DURATION)
.setListener(new AnimatorListenerAdapter() {
@Override
public void onAnimationEnd(Animator animation) {
setVisibility(View.GONE);
}
});
}
答案 7 :(得分:1)
我的解决方案扩展
fun View.slideVisibility(visibility: Boolean, durationTime: Long = 300) {
val transition = Slide(Gravity.BOTTOM)
transition.apply {
duration = durationTime
addTarget(this@slideVisibility)
}
TransitionManager.beginDelayedTransition(this.parent as ViewGroup, transition)
this.isVisible = visibility
}
使用:
textView.slideVisibility(true)
答案 8 :(得分:0)
找到下面的代码,使 Circuler 显示中的视图可见,如果你发送 true,它会得到 Invisible/Gone。如果你发送假,它会变得可见。 anyView 是您要显示/隐藏的视图,它可以是任何视图(布局、按钮等)
private fun toggle(flag: Boolean, anyView: View) {
if (flag) {
val cx = anyView.width / 2
val cy = anyView.height / 2
val initialRadius = Math.hypot(cx.toDouble(), cy.toDouble()).toFloat()
val anim = ViewAnimationUtils.createCircularReveal(anyView, cx, cy, initialRadius, 0f)
anim.addListener(object : AnimatorListenerAdapter() {
override fun onAnimationEnd(animation: Animator) {
super.onAnimationEnd(animation)
anyView.visibility = View.INVISIBLE
}
})
anim.start()
} else {
val cx = anyView.width / 2
val cy = anyView.height / 2
val finalRadius = Math.hypot(cx.toDouble(), cy.toDouble()).toFloat()
val anim = ViewAnimationUtils.createCircularReveal(anyView, cx, cy, 0f, finalRadius)
anyView.visibility = View.VISIBLE
anim.start()
}
}
