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

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>

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()
    }
}

你可以做两件事来添加动画，首先你可以让android为你动画布局的变化。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将自动创建渐隐/过渡动画。要使用这个集合

android:animateLayoutChanges="true"

在布局的根节点上。

第二个选择是手动添加动画。为此，我建议你使用Android 3.0 (Honeycomb)中引入的新动画API。我可以举几个例子:

淡出一个视图:

view.animate().alpha(0.0f);

这将淡入它:

view.animate().alpha(1.0f);

这将按高度向下移动视图:

view.animate().translationY(view.getHeight());

这将在视图被移动到其他位置后返回到它的起始位置:

view.animate().translationY(0);

你也可以使用setDuration()来设置动画的持续时间。例如，在2秒内淡出一个视图:

view.animate().alpha(0.0f).setDuration(2000);

你可以组合任意多的动画，例如这个淡出一个视图，并在0.3秒的时间内同时向下移动它:

view.animate()
        .translationY(view.getHeight())
        .alpha(0.0f)
        .setDuration(300);

And you can also assign a listener to the animation and react to all kinds of events. Like when the animation starts, when it ends or repeats etc. By using the abstract class AnimatorListenerAdapter you don't have to implement all callbacks of AnimatorListener at once but only those you need. This makes the code more readable. For example the following code fades out a View moves it down by its height over a period of 0.3 seconds (300 milliseconds) and when the animation is done its visibility is set to View.GONE.

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。

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

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);
