Question

我正在尝试设置 activity 出现的动画，但是当 activity 启动时，出现异常“java.lang.RuntimeException：未知场景名称：翻译”被抛出。

清单：

<activity android:name=".ui.createtarget.CreateTargetActivity" android:theme="@style/SlidingPanel"/>

Styles.xml:

<style name="SlidingPanel" parent="AppTheme">
        <item name="android:windowEnterTransition">@transition/slide_from_bottom</item>
        <item name="android:windowExitTransition">@transition/slide_to_bottom</item>
</style>

Activity布局xml:

android:theme="@style/SlidingPanel"

过渡xml:

<?xml version="1.0" encoding="utf-8"?>
<translate
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:duration="250"
    android:fromXDelta="-100%p"
    android:toXDelta="0%p">
</translate>

如果重要的话，我从这样的片段开始 activity：

private fun onCreateNewTask(){
        val intent = Intent(context, CreateTargetActivity::class.java)
        intent.putExtra("targetPosition",targetPosition)
        startActivity(intent, ActivityOptions.makeSceneTransitionAnimation(activity).toBundle())
    }

请告诉我如何解决这个问题！

您的转换 XML 不是有效的转换 - 这是在您调用 startActivity)

之后调用的 View Animation XML file, not a transition (you'd apply view animations via overridePendingTransition

根据 Start an activity using a transition guide, you need to use one the types listed there. In your case, it looks like you should be using a Slide Transition 和 Gravity.START 边缘：

<?xml version="1.0" encoding="utf-8"?>
<slide
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:duration="250"
    android:slideEdge="start">
</slide>

Android - 未知场景名称：翻译异常 - 开始 activity 时出现过渡

Android - Unknown scene name: translate exception - when starting activity with transition
