Android在setvisibility(view.Gone)时添加简单的动画

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

我的XML

找到下面的代码，使循环显示的视图可见，如果你发送真，它将得到隐形/消失。如果你发送false，它就会被看到。anyView是你要显示/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()
    }
}

我的解扩展

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
    }

Use:

textView.slideVisibility(true)

根据@Xaver Kapeller的回答，我想出了一种方法，当新视图出现在屏幕上时，创建滚动动画(以及隐藏它们的动画)。

它从这个状态开始

按钮 最后一个按钮

to

按钮 按钮1 按钮2 按钮3 按钮4 最后一个按钮

和亦然。

因此，当用户点击第一个按钮时，元素“button 1”，“button 2”，“button 3”和“button 4”将使用渐隐动画出现，元素“Last button”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:

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;
}

这是隐藏动画元素的代码:

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();
}

注意有一个简单的方法来隐藏动画。在动画监听器mHiddenLinearLayout上，我必须通过使用删除监听器本身:

mHiddenLinearLayout.animate().setListener(null);

这是因为一旦一个动画监听器被附加到一个视图，下一次当任何动画在这个视图中执行时，监听器也将被执行。这可能是动画监听器中的bug。

项目的源代码在GitHub上: https://github.com/jiahaoliuliu/ViewsAnimated

编码快乐!

更新:对于任何附加到视图的监听器，它应该在动画结束后被删除。这是通过使用

view.animate().setListener(null);

尝试将这一行添加到xml父布局中

 android:animateLayoutChanges="true"

你的布局看起来是这样的

<?xml version="1.0" encoding="UTF-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:animateLayoutChanges="true"
    android:longClickable="false"
    android:orientation="vertical"
    android:weightSum="16">

    .......other code here

    </LinearLayout>

基于@ashakirov的答案，这是我的扩展显示/隐藏视图与渐隐动画

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
}

示例使用

view.fadeVisibility(View.VISIBLE)
view.fadeVisibility(View.GONE, 2000)
2021-01-21 06:58:42

请检查这个链接。这将允许像L2R, R2L, T2B, B2T动画。

这段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);

如果你想从R2L开始，那么使用

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。
