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

Question

提问by arun

I have designed a simple layout.I have finished the design without animation, but now I want to add animations when textview click event and I don't know how to use it. Did my xml design looks good or not? Any suggestions would be appreciated.

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 设计看起来不错吗？任何建议，将不胜感激。

You can do two things to add animations, first you can let android animate layout changes for you. That way every time you change something in the layout like changing view visibility or view positions android will automatically create fade/transition animations. To use that set

你可以做两件事来添加动画，首先你可以让android为你设置动画布局。这样，每次您更改布局中的某些内容（例如更改视图可见性或视图位置）时，android 都会自动创建淡入淡出/过渡动画。使用该集合

android:animateLayoutChanges="true"

on the root node in your layout.

在布局中的根节点上。

Your second option would be to manually add animations. For this I suggest you use the new animation API introduced in Android 3.0 (Honeycomb). I can give you a few examples:

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。我可以给你举几个例子：

This fades out a View:

这淡出一个View：

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

This fades it back in:

这将它淡入：

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

This moves a Viewdown by its height:

这将View向下移动其高度：

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

This returns the Viewto its starting position after it has been moved somewhere else:

这将在View移动到其他地方后返回其起始位置：

view.animate().translationY(0);

You can also use setDuration()to set the duration of the animation. For example this fades out a Viewover a period of 2 seconds:

您还可以使用setDuration()来设置动画的持续时间。例如，这会View在 2 秒内淡出 a ：

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

And you can combine as many animations as you like, for example this fades out a Viewand moves it down at the same time over a period of 0.3 seconds:

您可以根据需要组合任意数量的动画，例如View在 0.3 秒的时间内淡出 a并同时将其向下移动：

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 AnimatorListenerAdapteryou don't have to implement all callbacks of AnimatorListenerat once but only those you need. This makes the code more readable. For example the following code fades out a Viewmoves 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.

您还可以为动画分配一个侦听器并对各种事件做出反应。就像动画开始时、结束时或重复时等。通过使用抽象类，AnimatorListenerAdapter您不必AnimatorListener一次实现所有回调，而只需实现您需要的回调。这使代码更具可读性。例如，以下代码淡出 aView在 0.3 秒（300 毫秒）的时间内将其向下移动其高度，并且当动画完成时，其可见性设置为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);
            }
        });

回答by NullPointerException

Please check thislink. Which will allow animations like L2R, R2L, T2B, B2T animations.

请检查此链接。这将允许 L2R、R2L、T2B、B2T 动画等动画。

This code shows animation from left to right

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);

if you want to do it from R2L then use

如果您想从 R2L 执行此操作，请使用

TranslateAnimation animate = new TranslateAnimation(0,-view.getWidth(),0,0);

for top to bottom as

从上到下作为

TranslateAnimation animate = new TranslateAnimation(0,0,0,view.getHeight());

and vice a versa..

反之亦然..

回答by jiahao

Based on the answer of @Xaver Kapeller I figured out a way to create scroll animation when new views appear on the screen (and also animation to hide them).

根据@Xaver Kapeller 的回答，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）。

It goes from this state:

它从这个状态开始：

Button
Last Button

按钮
最后一个按钮

to

到

Button
Button 1
Button 2
Button 3
Button 4
Last Button

按钮
按钮 1
按钮 2
按钮 3
按钮 4
最后一个按钮

and viceversa.

反之亦然。

So, when the user clicks on the first button, the elements "Button 1", "Button 2", "Button 3" and "Button 4" will appear using fade animation and the element "Last Button" will move down till end. The height of the layout will change as well, allowing using scroll view properly.

因此，当用户单击第一个按钮时，元素“按钮 1”、“按钮 2”、“按钮 3”和“按钮 4”将使用淡入淡出动画出现，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。

This is the code to show elements with animation:

这是显示带有动画的元素的代码：

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;
}

and this is the code to hide elements of the animation:

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();
}

Note there is a simple hack on the method to hide the animation. On the animation listener mHiddenLinearLayout, I had to remove the listener itself by using:

请注意，隐藏动画的方法有一个简单的技巧。在动画侦听器 mHiddenLinearLayout 上，我必须使用以下方法删除侦听器本身：

mHiddenLinearLayout.animate().setListener(null);

This is because once an animation listener is attached to an view, the next time when any animation is executed in this view, the listener will be executed as well. This might be a bug in the animation listener.

这是因为一旦动画侦听器附加到视图，下一次在此视图中执行任何动画时，侦听器也将被执行。这可能是动画侦听器中的错误。

The source code of the project is on GitHub: https://github.com/jiahaoliuliu/ViewsAnimated

项目源码在GitHub上：https: //github.com/jiahaoliuliu/ViewsAnimated

Happy coding!

快乐编码！

Update: For any listener attached to the views, it should be removed after the animation ends. This is done by using

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

view.animate().setListener(null);

Try adding this line to the xml parent layout

尝试将此行添加到 xml 父布局

 android:animateLayoutChanges="true"

Your layout will look like this

您的布局将如下所示

<?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>

The easiest way to animate Visibilitychanges is use Transition APIwhich available in support (androidx) package. Just call TransitionManager.beginDelayedTransitionmethod then change visibility of the view. There are several default transitions like Fade, Slide.

对Visibility更改进行动画处理的最简单方法是使用Transition API支持 (androidx) 包中提供的内容。只需调用TransitionManager.beginDelayedTransition方法然后更改视图的可见性。有几个默认转换，如Fade, Slide。

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);
}

Where parentis parent ViewGroupof animated view. Result:

动画视图的parent父级在哪里ViewGroup。结果：

Here is result with Slidetransition:

这是Slide转换的结果：

import androidx.transition.Slide;

Transition transition = new Slide(Gravity.BOTTOM);

It is easy to write custom transition if you need something different. Here is example with CircularRevealTransitionwhich I wrote in another answer. It shows and hide view with CircularReveal animation.

如果您需要不同的东西，很容易编写自定义过渡。这是CircularRevealTransition我在另一个答案中写的示例。它使用 CircularReveal 动画显示和隐藏视图。

Transition transition = new CircularRevealTransition();

android:animateLayoutChanges="true"option does same thing, it just uses AutoTransitionas transition.

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