Question

我需要像这样在Activities或Fragments之间制作动画。我使用Android Api >=14.

http://www.youtube.com/watch?v=cNMqIv5Ocnk - 这是Nexus5 Launcher

我已经尝试过使用Android ObjectAnimator的动画，但它与这个视频动画并不是很相似。

提前致谢。

我试过这段代码

（适用gla_on.xml）：

<objectAnimator
    android:duration="0"
    android:propertyName="alpha"
    android:valueFrom="1.0"
    android:valueTo="0.0" />
<objectAnimator
    android:duration="1000"
    android:interpolator="@android:interpolator/accelerate_decelerate"
    android:propertyName="scaleY"
    android:valueFrom="1"
    android:valueTo="12" />
<objectAnimator
    android:duration="1000"
    android:interpolator="@android:interpolator/accelerate_decelerate"
    android:propertyName="scaleX"
    android:valueFrom="1"
    android:valueTo="12" />

的 gla_off.xml：

<objectAnimator
    android:duration="0"
    android:propertyName="alpha"
    android:valueFrom="0.0"
    android:valueTo="1.0" />
<objectAnimator
    android:duration="1000"
    android:interpolator="@android:interpolator/accelerate_decelerate"
    android:propertyName="scaleY"
    android:valueFrom="1"
    android:valueTo="12" />
<objectAnimator
    android:duration="1000"
    android:interpolator="@android:interpolator/accelerate_decelerate"
    android:propertyName="scaleX"
    android:valueFrom="1"
    android:valueTo="12" />

并将其放入此代码片段中：

getFragmentManager()
        .beginTransaction()
        .setCustomAnimations(R.anim.gla_on, R.anim.gla_off)
        .replace(R.id.container, new NextFragment())
        .addToBackStack(null)
        .commit();

但是NextFragment没有显示

经过多次尝试，我找到了决定。

我在Android资源文件夹 anim

中创建了4个动画

<强> gla_there_come.xml

<set xmlns:android="http://schemas.android.com/apk/res/android" >

    <objectAnimator
        android:duration="500"
        android:propertyName="alpha"
        android:valueFrom="0.0"
        android:valueTo="1.0" />
    <objectAnimator
        android:duration="500"
        android:interpolator="@android:interpolator/accelerate_decelerate"
        android:propertyName="scaleY"
        android:valueFrom="0"
        android:valueTo="1" />
    <objectAnimator
        android:duration="500"
        android:interpolator="@android:interpolator/accelerate_decelerate"
        android:propertyName="scaleX"
        android:valueFrom="0"
        android:valueTo="1" />

</set>

<强> gla_there_gone.xml

<set xmlns:android="http://schemas.android.com/apk/res/android" >

    <objectAnimator
        android:duration="500"
        android:propertyName="alpha"
        android:valueFrom="1.0"

        android:propertyName="scaleY"
        android:valueFrom="1"
        android:valueTo="12" />
    <objectAnimator

        android:interpolator="@android:interpolator/accelerate_decelerate"
        android:propertyName="scaleX"
        android:valueFrom="1"
        android:valueTo="12" />

</set>

<强> gla_back_gone.xml

<set xmlns:android="http://schemas.android.com/apk/res/android" >

    <objectAnimator
        android:duration="500"
        android:propertyName="alpha"
        android:valueFrom="0.0"
        android:valueTo="1.0" />
    <objectAnimator
        android:duration="500"
        android:interpolator="@android:interpolator/accelerate_decelerate"
        android:propertyName="scaleY"
        android:valueFrom="12"
        android:valueTo="1" />
    <objectAnimator
        android:duration="500"
        android:interpolator="@android:interpolator/accelerate_decelerate"
        android:propertyName="scaleX"
        android:valueFrom="12"
        android:valueTo="1" />

</set>

<强> gla_back_come.xml

<set xmlns:android="http://schemas.android.com/apk/res/android" >

    <objectAnimator
        android:duration="500"
        android:propertyName="alpha"
        android:valueFrom="1.0"
        android:valueTo="0.0" />
    <objectAnimator
        android:duration="500"
        android:interpolator="@android:interpolator/accelerate_decelerate"
        android:propertyName="scaleY"
        android:valueFrom="1"
        android:valueTo="0" />
    <objectAnimator
        android:duration="500"
        android:interpolator="@android:interpolator/accelerate_decelerate"
        android:propertyName="scaleX"
        android:valueFrom="1"
        android:valueTo="0" />

</set>

我将下面的代码添加到我的FragmentActivity中：

public void goToNext() {
    mShowingNext = true;

    getFragmentManager()
            .beginTransaction()
            .setCustomAnimations(R.anim.gla_there_come, R.anim.gla_there_gone)
            .replace(R.id.container, new NextFragment())
            .commit();
}

public void goBack() {
    mShowingNext = false;

    getFragmentManager()
            .beginTransaction()
            .setCustomAnimations(R.anim.gla_back_gone, R.anim.gla_back_come)
            .replace(R.id.container, new MainFragment())
            .commit();
}

像Google Now Launcher Menu Animation这样的Android 3D动画
