Question

我试图通过将电流向左淡化并从右侧淡化新电流来动画两个片段之间的过渡。应用程序在运行时崩溃。

minSdkVersion： 16
targetSdkVersion： 23
模拟器在api版本23上运行

活动代码

    FragmentTransaction transaction = getFragmentManager().beginTransaction();
    transaction.setCustomAnimations(R.animator.enter_from_right, R.animator.exit_to_left);
    transaction.replace(R.id.listFragmentContainer, fragment);
    transaction.commit();

RES /动画/ enter_from_right.xml

<?xml version="1.0" encoding="utf-8"?>
<set xmlns:android="http://schemas.android.com/apk/res/android"
    android:shareInterpolator="false">
<ObjectAnimator
    android:fromXDelta="100%" android:toXDelta="0%"
    android:fromYDelta="0%" android:toYDelta="0%"
    android:duration="700"/>
</set>

RES /动画/ exit_to_left.xml

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

你只是想念objectAnimator元素

将ObjectAnimator更改为objectAnimator，就像这样

<强> RES /动画/ enter_from_right.xml

<?xml version="1.0" encoding="utf-8"?>
<set xmlns:android="http://schemas.android.com/apk/res/android"
    android:shareInterpolator="false">
<objectAnimator
    android:fromXDelta="100%" android:toXDelta="0%"
    android:fromYDelta="0%" android:toYDelta="0%"
    android:duration="700"/>
</set>

<强> RES /动画/ exit_to_left.xml

<?xml version="1.0" encoding="utf-8"?>
<set xmlns:android="http://schemas.android.com/apk/res/android"
    android:shareInterpolator="false">
<objectAnimator
    android:fromXDelta="0%" android:toXDelta="-100%"
    android:fromYDelta="0%" android:toYDelta="0%"
    android:duration="700"/>
</set>
