我有一个线性布局,我想显示或隐藏与动画,推动布局向上或向下每当我改变其可见性。
我在那里看过一些样品,但没有一个适合我的需要。
我已经为动画创建了两个xml文件,但我不知道当我改变线性布局的可见性时如何启动它们。

val transition: Transition = Slide(Gravity.BOTTOM)
transition.duration = 600
transition.addTarget(you_parent_layout_id)
TransitionManager.beginDelayedTransition(rootLayoutId, transition)
yourViewIdToHide.visibility = if (yourViewIdToHide.isShown) View.GONE else View.VISIBLE

你可以上下滑动任何视图或布局使用咆哮的代码在安卓应用程序
boolean isClicked = false;
LinearLayout mLayoutTab = (LinearLayout) findViewById(R.id.linearlayout);
if(isClicked) {
isClicked = false;
mLayoutTab.animate()
.translationYBy(120)
.translationY(0)
.setDuration(getResources().getInteger(android.R.integer.config_mediumAnimTime));
} else {
isClicked = true;
mLayoutTab.animate()
.translationYBy(0)
.translationY(120)
.setDuration(getResources().getInteger(android.R.integer.config_mediumAnimTime));
}
你可以使用简单的三行代码来显示动画…
//getting the hiding view by animation
mbinding.butn.setOnClickListener {
val SlideOutLeft = AnimationUtils.loadAnimation(this, R.anim.slide_out_left)
simplelayout.visibility = View.INVISIBLE
simplelayout.startAnimation(SlideOutLeft)
val SlideInRight = AnimationUtils.loadAnimation(applicationContext, R.anim.slide_in_right)
animation1.visibility = View.VISIBLE
animation1.startAnimation(SlideInRight)
}
//again unhide the view animation
mbinding.buttn.setOnClickListener {
val SlideInLeft=AnimationUtils.loadAnimation(this,R.anim.slide_in_left)
//set the layout
simplelayout.visibility=View.VISIBLE
simplelayout.startAnimation(SlideInLeft)
val SlideOutRight=AnimationUtils.loadAnimation(this,R.anim.slide_out_right)
animation1.visibility=View.INVISIBLE
animation1.startAnimation(SlideOutRight)
}

使用ObjectAnimator
private fun slideDown(view: View) {
val height = view.height
ObjectAnimator.ofFloat(view, View.TRANSLATION_Y, 0f, height.toFloat()).apply {
duration = 1000
start()
}
}
private fun slideUp(view: View) {
val height = view.height
ObjectAnimator.ofFloat(view, View.TRANSLATION_Y, height.toFloat(), 0f)).apply {
duration = 1000
start()
}
}
如果你想同时显示/隐藏多个视图,你可以使用TransitionSet(因为你不能同时播放2个“单个”过渡)
fun slideTopBottomVisibility(topLayout: View, bottomLayout: View, show: Boolean) {
val topTransition: Transition = Slide(Gravity.TOP)
topTransition.duration = 600
topTransition.addTarget(topLayout)
val bottomTransition: Transition = Slide(Gravity.BOTTOM)
bottomTransition.duration = 600
bottomTransition.addTarget(bottomLayout)
val transitionSet = TransitionSet()
transitionSet.addTransition(topTransition)
transitionSet.addTransition(bottomTransition)
TransitionManager.beginDelayedTransition(topLayout.parent as ViewGroup, transitionSet)
topLayout.visibility = if (show) View.VISIBLE else View.GONE
bottomLayout.visibility = if (show) View.VISIBLE else View.GONE
}
