我看过一些动画片段之间的交互的教程。我用这个方法制作动画,效果很好:

fragmentTransaction.setCustomAnimations(android.R.anim.slide_in_left,
                android.R.anim.slide_out_right);

但我想把这个动画倒过来:旧片段滑出到左侧,新片段滑入到右侧,但R.anim文件的值似乎对我的作用域没有用处。
我该怎么做呢?

您可以创建自己的动画。将动画XML文件放置在res > anim
enter_from_left.xml

<?xml version="1.0" encoding="utf-8"?>
<set xmlns:android="http://schemas.android.com/apk/res/android"
     android:shareInterpolator="false">
  <translate 
      android:fromXDelta="-100%p" android:toXDelta="0%"
      android:fromYDelta="0%" android:toYDelta="0%"
      android:duration="@android:integer/config_mediumAnimTime"/>
</set>

enter_from_right.xml

<?xml version="1.0" encoding="utf-8"?>
<set xmlns:android="http://schemas.android.com/apk/res/android"
     android:shareInterpolator="false">
  <translate
     android:fromXDelta="100%p" android:toXDelta="0%"
     android:fromYDelta="0%" android:toYDelta="0%"
     android:duration="@android:integer/config_mediumAnimTime" />
</set>

exit_to_left.xml

<?xml version="1.0" encoding="utf-8"?>
<set xmlns:android="http://schemas.android.com/apk/res/android"
     android:shareInterpolator="false">
  <translate 
      android:fromXDelta="0%" android:toXDelta="-100%p"
      android:fromYDelta="0%" android:toYDelta="0%"
      android:duration="@android:integer/config_mediumAnimTime"/>
</set>

exit_to_right.xml

<?xml version="1.0" encoding="utf-8"?>
<set xmlns:android="http://schemas.android.com/apk/res/android"
     android:shareInterpolator="false">
  <translate
     android:fromXDelta="0%" android:toXDelta="100%p"
     android:fromYDelta="0%" android:toYDelta="0%"
     android:duration="@android:integer/config_mediumAnimTime" />
</set>

你可以改变持续时间到短动画时间

android:duration="@android:integer/config_shortAnimTime"

或长动画时间

android:duration="@android:integer/config_longAnimTime"

用法(注意,对事务调用方法的顺序很重要。在调用.replace、.commit之前添加动画):

FragmentTransaction transaction = supportFragmentManager.beginTransaction();
transaction.setCustomAnimations(R.anim.enter_from_right, R.anim.exit_to_left, R.anim.enter_from_left, R.anim.exit_to_right);
transaction.replace(R.id.content_frame, fragment);
transaction.addToBackStack(null);
transaction.commit();

有三种方法可以在片段中实现事务动画。

转换

因此需要使用其中一个内置的Transitions,使用setTranstion()方法:

getSupportFragmentManager()
        .beginTransaction()
        .setTransition( FragmentTransaction.TRANSIT_FRAGMENT_OPEN )
        .show( m_topFragment )
        .commit()

自定义动画

也可以使用setCustomAnimations()方法自定义动画:

getSupportFragmentManager()
        .beginTransaction()
        .setCustomAnimations( R.anim.slide_up, 0, 0, R.anim.slide_down)
        .show( m_topFragment )
        .commit()

向上滑动.xml

<?xml version="1.0" encoding="utf-8"?>
<objectAnimator
        xmlns:android="http://schemas.android.com/apk/res/android"
        android:interpolator="@android:anim/accelerate_decelerate_interpolator"
        android:propertyName="translationY"
        android:valueType="floatType"
        android:valueFrom="1280"
        android:valueTo="0"
        android:duration="@android:integer/config_mediumAnimTime"/>

向下滑动.xml

<?xml version="1.0" encoding="utf-8"?>
<objectAnimator
        xmlns:android="http://schemas.android.com/apk/res/android"
        android:interpolator="@android:anim/accelerate_decelerate_interpolator"
        android:propertyName="translationY"
        android:valueType="floatType"
        android:valueFrom="0"
        android:valueTo="1280"
        android:duration="@android:integer/config_mediumAnimTime"/>

多个动画

最后,还可以在一个事务中启动多个片段动画,这样可以实现一个片段向上滑动,而另一个片段同时向下滑动的非常酷的效果:

getSupportFragmentManager()
        .beginTransaction()
        .setCustomAnimations( R.anim.abc_slide_in_top, R.anim.abc_slide_out_top ) // Top Fragment Animation
        .show( m_topFragment )
        .setCustomAnimations( R.anim.abc_slide_in_bottom, R.anim.abc_slide_out_bottom ) // Bottom Fragment Animation
        .show( m_bottomFragment )
        .commit()

**注:-**您可以根据您的要求检查动画,因为上面可能有问题。

slide_in_down.xml

<?xml version="1.0" encoding="utf-8"?>
<set xmlns:android="http://schemas.android.com/apk/res/android">
    <translate
        android:duration="@android:integer/config_longAnimTime"
        android:fromYDelta="0%p"

        android:toYDelta="-100%p"
        />

方向=向下

activity.getSupportFragmentManager()
                    .beginTransaction()
                    .setCustomAnimations(R.anim.slide_out_down, R.anim.slide_in_down)
                    .replace(R.id.container, new CardFrontFragment())
                    .commit();

方向=向上

activity.getSupportFragmentManager()
                    .beginTransaction()
                    .setCustomAnimations(R.anim.slide_in_up, R.anim.slide_out_up)
                    .replace(R.id.container, new CardFrontFragment())
                    .commit();

我遇到了同样的问题,我使用了简单的解决方案
1)在动画文件夹中创建sliding_out_right. xml

<?xml version="1.0" encoding="utf-8"?>
    <set xmlns:android="http://schemas.android.com/apk/res/android">
        <translate android:fromXDelta="0" android:toXDelta="-50%p"
            android:duration="@android:integer/config_mediumAnimTime"/>
        <alpha android:fromAlpha="1.0" android:toAlpha="0.0"
            android:duration="@android:integer/config_mediumAnimTime" />
    </set>

2)在动画文件夹中创建sliding_in_left. xml

<?xml version="1.0" encoding="utf-8"?>
<set xmlns:android="http://schemas.android.com/apk/res/android">
    <translate android:fromXDelta="50%p" android:toXDelta="0"
        android:duration="@android:integer/config_mediumAnimTime"/>
    <alpha android:fromAlpha="0.0" android:toAlpha="1.0"
        android:duration="@android:integer/config_mediumAnimTime" />
</set>

3)简单地使用片段事务setCustomeAnimations()和两个自定义xml以及两个默认xml进行动画,如下所示:

fragmentTransaction.setCustomAnimations(R.anim.sliding_in_left, R.anim.sliding_out_right, android.R.anim.slide_in_left, android.R.anim.slide_out_right );

这是我使用的另一个解决方案:

public class CustomAnimator {
    private static final String TAG = "com.example.CustomAnimator";

    private static Stack<AnimationEntry> animation_stack    = new Stack<>();

    public static final int                 DIRECTION_LEFT  = 1;
    public static final int                 DIRECTION_RIGHT = -1;
    public static final int                 DIRECTION_UP    = 2;
    public static final int                 DIRECTION_DOWN  = -2;

    static class AnimationEntry {
        View in;
        View    out;
        int     direction;
        long    duration;
    }

    public static boolean hasHistory() {
        return !animation_stack.empty();
    }

    public static void reversePrevious() {
        if (!animation_stack.empty()) {
            AnimationEntry entry = animation_stack.pop();
            slide(entry.out, entry.in, -entry.direction, entry.duration, false);
        }
    }

    public static void clearHistory() {
        animation_stack.clear();
    }

    public static void slide(final View in, View out, final int direction, long duration) {
        slide(in, out, direction, duration, true);
    }

    private static void slide(final View in, final View out, final int direction, final long duration, final boolean save) {

        ViewGroup in_parent = (ViewGroup) in.getParent();
        ViewGroup out_parent = (ViewGroup) out.getParent();

        if (!in_parent.equals(out_parent)) {
            return;
        }

        int parent_width = in_parent.getWidth();
        int parent_height = in_parent.getHeight();

        ObjectAnimator slide_out;
        ObjectAnimator slide_in;

        switch (direction) {
            case DIRECTION_LEFT:
            default:
                slide_in = ObjectAnimator.ofFloat(in, "translationX", parent_width, 0);
                slide_out = ObjectAnimator.ofFloat(out, "translationX", 0, -out.getWidth());
                break;
            case DIRECTION_RIGHT:
                slide_in = ObjectAnimator.ofFloat(in, "translationX", -out.getWidth(), 0);
                slide_out = ObjectAnimator.ofFloat(out, "translationX", 0, parent_width);
                break;
            case DIRECTION_UP:
                slide_in = ObjectAnimator.ofFloat(in, "translationY", parent_height, 0);
                slide_out = ObjectAnimator.ofFloat(out, "translationY", 0, -out.getHeight());
                break;
            case DIRECTION_DOWN:
                slide_in = ObjectAnimator.ofFloat(in, "translationY", -out.getHeight(), 0);
                slide_out = ObjectAnimator.ofFloat(out, "translationY", 0, parent_height);
                break;
        }

        AnimatorSet animations = new AnimatorSet();
        animations.setDuration(duration);
        animations.playTogether(slide_in, slide_out);
        animations.addListener(new Animator.AnimatorListener() {

            @Override
            public void onAnimationCancel(Animator arg0) {
            }

            @Override
            public void onAnimationEnd(Animator arg0) {
                out.setVisibility(View.INVISIBLE);
                if (save) {
                    AnimationEntry ae = new AnimationEntry();
                    ae.in = in;
                    ae.out = out;
                    ae.direction = direction;
                    ae.duration = duration;
                    animation_stack.push(ae);
                }
            }

            @Override
            public void onAnimationRepeat(Animator arg0) {
            }

            @Override
            public void onAnimationStart(Animator arg0) {
                in.setVisibility(View.VISIBLE);
            }
        });
        animations.start();
    }
}

类的用法。假设你有两个片段(list和details片段),如下所示

<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/ui_container"
    android:layout_width="match_parent"
    android:layout_height="match_parent" >

    <FrameLayout
        android:id="@+id/list_container"
        android:layout_width="match_parent"
        android:layout_height="match_parent" />

    <FrameLayout
        android:id="@+id/details_container"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:visibility="gone" />
</FrameLayout>

用法

View details_container = findViewById(R.id.details_container);
View list_container = findViewById(R.id.list_container);
// You can select the direction left/right/up/down and the duration
CustomAnimator.slide(list_container, details_container,CustomAnimator.DIRECTION_LEFT, 400);

当用户按下返回键时,可以使用函数CustomAnimator.reversePrevious();获取上一个视图。

在从一个片段过渡到另一个片段的过程中也有同样的白色问题。在navigation.xml中设置导航和动画。

所有片段中的背景相同,但白色空白屏幕。因此,我在执行过渡期间设置片段中的navOptions

//Transition options
        val options = navOptions {
            anim {
                enter = R.anim.slide_in_right
                exit = R.anim.slide_out_left
                popEnter = R.anim.slide_in_left
                popExit = R.anim.slide_out_right
            }
        }

.......................

  this.findNavController().navigate(SampleFragmentDirections.actionSampleFragmentToChartFragment(it),
                    options)

这对我很有效。转换之间没有白色。神奇)

对我来说,唯一能够去除动画上白色背景的方法是,我更改为DialogFragment而不是Fragment,并添加以下代码:
创建了以下样式:

<style name="WindowSlideInAndOutAnimation">
        <item name="android:windowEnterAnimation">@anim/slide_in_bottom</item>
        <item name="android:windowExitAnimation">@anim/slide_out_top</item>
    </style>

    <style name="AppFullScreenDialogTransparentTitleBar" parent="Theme.MaterialComponents.Light.Dialog">
        <item name="android:windowBackground">@android:color/transparent</item>
        <item name="android:windowNoTitle">true</item>
        <item name="android:windowIsFloating">false</item>
        <item name="colorPrimaryDark">@android:color/transparent</item>
    </style>

然后在对话框片段中引用这些样式,如下所示:

override fun getTheme() = R.style.AppFullScreenDialogTransparentTitleBar

override fun onViewCreated(view: View, savedInstanceState: Bundle?) {
        super.onViewCreated(view, savedInstanceState)
        dialog?.window?.setWindowAnimations(R.style.WindowSlideInAndOutAnimation)

//rest of code on view created here
}

然后我就像平常一样通过导航组件导航到片段(还要注意将导航XML文件中片段的类型更改为对话框)
