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

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);
            }
        });

最简单的方法是使用过渡API，支持(androidx)包。只需调用TransitionManager。beginDelayedTransition方法，然后改变视图的可见性。有几个默认的过渡，如渐隐，滑动。

import androidx.transition.TransitionManager;
import androidx.transition.Transition;
import androidx.transition.Fade;

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ViewGroup。结果:

下面是幻灯片转换的结果:

import androidx.transition.Slide;

Transition transition = new Slide(Gravity.BOTTOM);

如果你需要一些不同的东西，很容易编写自定义转换。下面是我在另一个答案中写的CircularRevealTransition的例子。它用CircularReveal动画显示和隐藏视图。

Transition transition = new CircularRevealTransition();

android:animateLayoutChanges="true"选项做同样的事情，它只是使用AutoTransition作为过渡。

我可以这样显示/隐藏菜单:

java(扩展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);
                }
            });
}

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)

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>
