Slide left/right animation between fragments
提问by ludriv
I post a question here because I can't find out a solution to my problem. I read a lot of things about android animation.
我在这里发布了一个问题，因为我找不到解决我的问题的方法。我读了很多关于android动画的东西。
I actually develop an android 4.0 app and I need to animate transition between fragments (not layout).
我实际上开发了一个 android 4.0 应用程序，我需要动画片段之间的过渡（不是布局）。
Similary post, worked with layout but no more precision about fragments
Here my uncomplete code :
这是我不完整的代码：
Activity code
活动代码
private void showFragment(final Fragment fragment)
{
if (null == fragment)
return;
FragmentTransaction ft = getFragmentManager().beginTransaction();
ft.setCustomAnimations(R.anim.slide_in_left, R.anim.slide_out_right);
ft.replace(R.id.fragment_container_layout, fragment, fragment.getClass().getSimpleName()).commit();
}
R.anim.slide_in_left
R.anim.slide_in_left
<?xml version="1.0" encoding="utf-8"?> <set xmlns:android="http://schemas.android.com/apk/res/android"
android:duration="@android:integer/config_mediumAnimTime">
<translate
android:fromXDelta="100%p"
android:toXDelta="0" />
<alpha
android:fromAlpha="0.0"
android:toAlpha="1.0" />
</set>
And finally R.anim.slide_out_right
最后是R.anim.slide_out_right
<?xml version="1.0" encoding="utf-8"?>
<set xmlns:android="http://schemas.android.com/apk/res/android"
android:duration="@android:integer/config_mediumAnimTime" >
<translate
android:fromXDelta="0"
android:toXDelta="-100%p" />
<alpha
android:fromAlpha="1.0"
android:toAlpha="0.0" />
</set>
When I run this code, I got an exception : 12-27 15:26:55.566: E/AndroidRuntime(27699): java.lang.RuntimeException: Unknown animator name: translate
当我运行此代码时，出现异常： 12-27 15:26:55.566: E/AndroidRuntime(27699): java.lang.RuntimeException: Unknown animator name: translate
Do you have any idea to fix this ?
你有什么想法来解决这个问题吗？

Problem solved!
问题解决了！
Like Piyush Gupta said, I must have a custom subclass of FrameLayoutper FragmentI need to animate, first.
就像 Piyush Gupta 所说的那样，首先我必须有一个自定义的子类FrameLayoutper FragmentI 需要动画。
Secondly, I must not use R.animbut R.animatorlike another similar post (link in question).
其次，我不能使用R.anim但R.animator喜欢另一个类似的帖子（有问题的链接）。
Thank you all !
谢谢你们 ！
