Fragment v4动画崩溃

Question

我使用的是最小API = 14的片段v4。

    FragmentTransaction ft = getSupportFragmentManager().beginTransaction();        
    ft.setCustomAnimations(
             R.anim.fragment_slide_left_enter,
             R.anim.fragment_slide_left_exit,
             R.anim.fragment_slide_right_enter,
             R.anim.fragment_slide_right_exit);
    ft.replace(R.id.content_frame, myLogFragment).commit(); 

但是当我使用动画时，应用程序崩溃了

我怎么才能修复它呢？

Answer 1

您必须将您的R.anim文件转换为R.animation

http://developer.android.com/guide/topics/graphics/prop-animation.html#declaring-xml

要区分使用新属性动画API的动画文件和使用旧视图动画框架的动画文件，从Android3.1开始，您应该将属性动画的XML文件保存在res/animator/目录中(而不是res/anim/)。使用动画程序目录名是可选的，但如果您想要使用Eclipse ADT插件(ADT 11.0.0+)中的布局编辑器工具，则必须使用，因为ADT只在res/ animator /目录中搜索属性动画资源。

Answer 2

您正在尝试从support library在FragmentTransaction上应用objectAnimator。但是支持库只能应用像Alpha，Translation... AnimatorSet这样的ValueProperty动画

<translate
xmlns:android="http://schemas.android.com/apk/res/android"
android:duration="@android:integer/config_shortAnimTime"
android:fromXDelta="-100%p"
android:interpolator="@android:anim/decelerate_interpolator"
android:toXDelta="0%p"/>
