Question

我正在使用片段v4，最小API = 14。

    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

我该如何解决？

Answer 1

您必须将R.anim个文件转换为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版视图动画框架的动画文件，从Android 3.1开始，您应该在res / animator /目录中保存属性动画的XML文件（而不是res /阿尼姆/）。使用animator目录名是可选的，但是如果你想使用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只搜索res / animator /目录中的属性动画资源。

Answer 2

您正试图从objectAnimator FragmentTransaction申请support library。但支持库只能应用ValueProperty，Alpha等Translation动画... AnimatorSet

<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"/>

试试这个
