Animation transition between activities using FLAG_ACTIVITY_CLEAR_TOP
提问by Romain Piel
In my android app, I'm making a method that pop all activities and bring up the first activity.
在我的 android 应用程序中，我正在制作一种弹出所有活动并调出第一个活动的方法。
I use this code:
我使用这个代码：
Intent intent = new Intent(this, MMConnection.class);
intent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
this.startActivity(intent);
As I noticed that the transition was still a left to right animation, does someone know if there is a way to change system animation when starting an activity?
当我注意到过渡仍然是从左到右的动画时，有人知道是否有办法在开始活动时更改系统动画？
Actually, I'd ideally like to have a right to left transition (like when the return button is tapped)
实际上，我希望有一个从右到左的过渡（比如点击返回按钮时）
thanks for help!
感谢帮助！

CoolMcGrr is right, you want to use overridePendingTransition(int enterAnim, int exitAnim).
CoolMcGrr 是对的，您想使用overridePendingTransition(int enterAnim, int exitAnim).
To specifically get the standard "back button" transition, I use these as the enterAnimand exitAnimtransitions:
为了专门获得标准的“后退按钮”转换，我使用这些作为enterAnim和exitAnim转换：
push_right_in.xml
push_right_in.xml
<?xml version="1.0" encoding="utf-8"?>
<set xmlns:android="http://schemas.android.com/apk/res/android">
<translate android:fromXDelta="-100%p" android:toXDelta="0" android:duration="@android:integer/config_shortAnimTime"/>
<alpha android:fromAlpha="0.0" android:toAlpha="1.0" android:duration="@android:integer/config_shortAnimTime" />
</set>
push_right_out.xml
push_right_out.xml
<?xml version="1.0" encoding="utf-8"?>
<set xmlns:android="http://schemas.android.com/apk/res/android">
<translate android:fromXDelta="0" android:toXDelta="100%p" android:duration="@android:integer/config_shortAnimTime"/>
<alpha android:fromAlpha="1.0" android:toAlpha="0.0" android:duration="@android:integer/config_shortAnimTime" />
</set>

You should take a look Activity.overridePendingTransition().
你应该看看Activity.overridePendingTransition()。
Of course, this requires that you run at least version 2.0 of the SDK.
当然，这要求您至少运行 2.0 版的 SDK。

Problem occurs nowadays because pre-ICS and ICS have different built-in activity transitions. This is much cleaner than defining your own animation and SDK independant:
现在出现问题是因为 pre-ICS 和 ICS 具有不同的内置活动转换。这比定义你自己的动画和 SDK 独立得多：
Intent intent = new Intent(this, MMConnection.class);
intent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP|Intent.FLAG_ACTIVITY_NO_ANIMATION);
this.startActivity(intent);
finish();
This will start the activity (not visible yet) and play the "activity finish" transition to the new activity.
这将启动活动（尚不可见）并播放“活动完成”过渡到新活动。

I used this code:
我使用了这个代码：
overridePendingTransition(android.R.anim.fade_in, android.R.anim.fade_out);
You can see these examples in GmailAnimationor LopeAnimations. Also you can see more in this Blog.
您可以在GmailAnimation或LopeAnimations 中看到这些示例。你也可以在这个博客中看到更多。
