android转场动画（Activity和Fragment切换动

效果图

Activity切换动画

动画执行优先级，系统动画<AppTheme<(overridePendingTransition\ActivityOptionsCompat)）

1.overridePendingTransition（）

官方简介
Activity.jpg

下面放code：
R.anim.in_activity
R.anim.out_activity
R.anim.in_activity_close
R.anim.out_activity_close
资源文件放anim

in_activity

<?xml version="1.0" encoding="utf-8"?>
<set xmlns:android="http://schemas.android.com/apk/res/android">
    <translate
        android:fromYDelta="100%"
        android:toYDelta="0%"
        android:duration="300"
        />
</set>

out_activity

<?xml version="1.0" encoding="utf-8"?>
<set xmlns:android="http://schemas.android.com/apk/res/android">
    <translate
        android:duration="300"
        android:fromYDelta="0%"
        android:toYDelta="0%"
        />
</set>

in_activity_close

<?xml version="1.0" encoding="utf-8"?>
<set xmlns:android="http://schemas.android.com/apk/res/android">
    <translate
        android:fromYDelta="0%"
        android:toYDelta="0%"
        android:duration="300"
        />
</set>

out_activity_close

<?xml version="1.0" encoding="utf-8"?>
<set xmlns:android="http://schemas.android.com/apk/res/android">
    <translate
        android:duration="300"
        android:fromYDelta="0%"
        android:toYDelta="100%"
        />
</set>

2.Theme方式

    <!-- Base application theme. -->
    <style name="AppTheme" parent="Base.Theme.AppCompat.Light.DarkActionBar">
        <!-- Customize your theme here. -->
        <item name="colorPrimary">@color/colorPrimary</item>
        <item name="colorPrimaryDark">@color/colorPrimaryDark</item>
        <item name="colorAccent">@color/colorAccent</item>
        <item name="android:windowAnimationStyle">@style/myWindowAnim</item>
    </style>

    <style name="myWindowAnim">
        <item name="android:activityOpenEnterAnimation">@anim/in_activity</item>
        <item name="android:activityOpenExitAnimation">@anim/out_activity</item>
        <item name="android:activityCloseEnterAnimation">@anim/in_activity_close</item>
        <item name="android:activityCloseExitAnimation">@anim/out_activity_close</item>
    </style>

主题添加 <item name="android:windowAnimationStyle">@style/myWindowAnim</item>
这样全局都有动画了，不用每个Activity单独设置了。
资源文件同上

ActivityOptionsCompat( )

有兼容包，当然5.0以下没有动画效果。
看API名字应该就能知道了

1. ActivityOptionsCompat.makeCustomAnimation(Context context, int enterResId, int exitResId)【相当于overridePendingTransition】
2. ActivityOptionsCompat.makeScaleUpAnimation(View source,int startX, int startY, int startWidth, int startHeight)
3. ActivityOptionsCompat.makeThumbnailScaleUpAnimation(View source,Bitmap thumbnail, int startX, int startY)

共享属性

4. ActivityOptionsCompat.makeSceneTransitionAnimation(Activity activity, View sharedElement, String sharedElementName)
5. ActivityOptionsCompat.makeSceneTransitionAnimation(Activity activity,Pair<View, String>… sharedElements)

//                startActivity(new Intent(this, Main2Activity.class));
//                overridePendingTransition(R.anim.in_activity, R.anim.out_activity);
//                ActivityOptionsCompat activityOptionsCompat = ActivityOptionsCompat.makeCustomAnimation(this, R.anim
//                        .in_activity, R.anim.out_activity);
//                ActivityOptionsCompat activityOptionsCompat = ActivityOptionsCompat.makeScaleUpAnimation(v,
//                        v.getWidth() , v.getHeight() , 0, 0);
//                Bitmap bitmap = BitmapFactory.decodeResource(getResources(), R.mipmap.ic_launcher);
//                ActivityOptionsCompat activityOptionsCompat = ActivityOptionsCompat.makeThumbnailScaleUpAnimation(v,
//                        bitmap, v.getWidth(), v.getHeight());
                ActivityOptionsCompat activityOptionsCompat = ActivityOptionsCompat.makeSceneTransitionAnimation(
                        this, v, "sharedElement");
                ActivityCompat.startActivity(this, new Intent(this, B.class),
                        activityOptionsCompat.toBundle());

这里注意：ActivityCompat.startActivity（）。

Android 5.0（API 级别 21）支持这些共享元素转换：
changeBounds - 为目标视图的布局边界的变化添加动画。
changeClipBounds - 为目标视图的裁剪边界的变化添加动画。
changeTransform - 为目标视图的缩放与旋转变化添加动画。
changeImageTransform - 为目标图像的大小与缩放变化添加动画。

<transitionSet xmlns:android="http://schemas.android.com/apk/res/android">
    <changeBounds   android:interpolator="@android:interpolator/accelerate_decelerate"
        android:duration="500"/>
</transitionSet>

<style name="BaseAppTheme" parent="android:Theme.Material">
  <!-- enable window content transitions -->
  <item name="android:windowContentTransitions">true</item>

  <!-- specify enter and exit transitions -->
  <item name="android:windowEnterTransition">@transition/explode</item>
  <item name="android:windowExitTransition">@transition/explode</item>

  <!-- specify shared element transitions -->
  <item name="android:windowSharedElementEnterTransition">
    @transition/change_image_transform</item>
  <item name="android:windowSharedElementExitTransition">
    @transition/change_image_transform</item>
</style>

Fragment切换动画

资源文件放在animator
Fragment转场动画和Activity转场有点不同的是，Fragment只要在跳转页设置就行。

fragment_slide_left_enter

<?xml version="1.0" encoding="utf-8"?>
<set xmlns:android="http://schemas.android.com/apk/res/android">
    <objectAnimator

        android:valueFrom="1000" android:valueTo="0"
        android:valueType="floatType"
        android:propertyName="translationX"
        android:duration="@android:integer/config_mediumAnimTime" />
    <!--<objectAnimator-->
