我正在尝试动画片段之间的过渡。我从下面得到了答案 Android Fragments和动画

FragmentTransaction ft = getFragmentManager().beginTransaction();
ft.setCustomAnimations(R.anim.slide_in_left, R.anim.slide_out_right);

DetailsFragment newFragment = DetailsFragment.newInstance();

ft.replace(R.id.details_fragment_container, newFragment, "detailFragment");

// Start the animated transition.
ft.commit();

我的r。anm。slide_in_left

<?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>

但当我试着这样做时,它就出现了

02-08 16:27:37.961: ERROR/AndroidRuntime(1717): FATAL EXCEPTION: main

什么好主意吗?当我检查蜂窝API参考翻译有。我错过了什么? 有没有其他方法来动画片段之间的过渡? 谢谢你!


当前回答

对于其他任何被捕获的人,确保在构建事务时调用replace/add之前调用setCustomAnimations。

其他回答

我是这样做的:

添加这个方法来用动画替换片段:

public void replaceFragmentWithAnimation(android.support.v4.app.Fragment fragment, String tag){
    FragmentTransaction transaction = getSupportFragmentManager().beginTransaction();
    transaction.setCustomAnimations(R.anim.enter_from_left, R.anim.exit_to_right, R.anim.enter_from_right, R.anim.exit_to_left);
    transaction.replace(R.id.fragment_container, fragment);
    transaction.addToBackStack(tag);
    transaction.commit();
}

你必须在anim文件夹中添加四个与资源相关的动画:

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%" android:toXDelta="0%"
        android:fromYDelta="0%" android:toYDelta="0%"
        android:duration="700"/>
</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%"
        android:fromYDelta="0%" android:toYDelta="0%"
        android:duration="700" />
</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%" android:toXDelta="0%"
        android:fromYDelta="0%" android:toYDelta="0%"
        android:duration="700" />
</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%"
        android:fromYDelta="0%" android:toYDelta="0%"
        android:duration="700"/>
</set>

输出:

它的完成。

尝试使用这个简单快速的解决方案。Android提供了一些默认动画。

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

FragmentManager fragmentManager = getSupportFragmentManager();
FragmentTransaction fragmentTransaction = fragmentManager.beginTransaction();
fragmentTransaction.setCustomAnimations(android.R.anim.slide_in_left, android.R.anim.slide_out_right);
fragmentManager.addOnBackStackChangedListener(this);
fragmentTransaction.replace(R.id.frame, firstFragment, "h");
fragmentTransaction.addToBackStack("h");
fragmentTransaction.commit();

输出:

为了给这个老问题添加一个更现代的答案,如果你已经转移到材料设计,这可以很容易地使用提供的运动库——更多细节,请访问https://material.io/develop/android/theming/motion。

对于其他任何被捕获的人,确保在构建事务时调用replace/add之前调用setCustomAnimations。

下面是片段之间的幻灯片进出动画:

FragmentTransaction transaction = getFragmentManager().beginTransaction();
transaction.setCustomAnimations(R.animator.enter_anim, R.animator.exit_anim);
transaction.replace(R.id.listFragment, new YourFragment());
transaction.commit();

我们正在使用一个objectAnimator。

下面是animator子文件夹中的两个xml文件。

enter_anim.xml

<?xml version="1.0" encoding="utf-8"?>
<set>
     <objectAnimator
         xmlns:android="http://schemas.android.com/apk/res/android"
         android:duration="1000"
         android:propertyName="x"
         android:valueFrom="2000"
         android:valueTo="0"
         android:valueType="floatType" />
</set>

exit_anim.xml

<?xml version="1.0" encoding="utf-8"?>
<set>
    <objectAnimator
        xmlns:android="http://schemas.android.com/apk/res/android"
        android:duration="1000"
        android:propertyName="x"
        android:valueFrom="0"
        android:valueTo="-2000"
        android:valueType="floatType" />
</set>

我希望这能帮助到一些人。
