片段交易动画:滑入滑出 [英] Fragment transaction animation: slide in and slide out

问题描述

我查看了一些关于片段之间动画事务的教程.我已经使用这种方法制作动画并且它有效:

I've check some tutorials for animate transaction between fragments. I've used this method for animation and it works:

fragmentTransaction.setCustomAnimations(android.R.anim.slide_in_left,
                android.R.anim.slide_out_right);

但我想反转这个动画:旧片段向左滑出，新片段向右滑入，但 R.anim 文件的值似乎对我的范围没有用.

But I want to invert this animation: old fragment slide out to the left, and new fragment slide in to the right, but no value of R.anim file seems to be useful for my scope.

我该怎么做?

您可以创建自己的动画.将动画 XML 文件放在 res >动画

You can create your own animations. Place animation XML files in res > anim

enter_from_left.xml

enter_from_left.xml

<?xml version="1.0" encoding="utf-8"?>
<set xmlns:android="http://schemas.android.com/apk/res/android"
     android:shareInterpolator="false">
  <translate 
      android:fromXDelta="-100%p" android:toXDelta="0%"
      android:fromYDelta="0%" android:toYDelta="0%"
      android:duration="@android:integer/config_mediumAnimTime"/>
</set>

enter_from_right.xml

enter_from_right.xml

<?xml version="1.0" encoding="utf-8"?>
<set xmlns:android="http://schemas.android.com/apk/res/android"
     android:shareInterpolator="false">
  <translate
     android:fromXDelta="100%p" android:toXDelta="0%"
     android:fromYDelta="0%" android:toYDelta="0%"
     android:duration="@android:integer/config_mediumAnimTime" />
</set>

exit_to_left.xml

exit_to_left.xml

<?xml version="1.0" encoding="utf-8"?>
<set xmlns:android="http://schemas.android.com/apk/res/android"
     android:shareInterpolator="false">
  <translate 
      android:fromXDelta="0%" android:toXDelta="-100%p"
      android:fromYDelta="0%" android:toYDelta="0%"
      android:duration="@android:integer/config_mediumAnimTime"/>
</set>

exit_to_right.xml

exit_to_right.xml

<?xml version="1.0" encoding="utf-8"?>
<set xmlns:android="http://schemas.android.com/apk/res/android"
     android:shareInterpolator="false">
  <translate
     android:fromXDelta="0%" android:toXDelta="100%p"
     android:fromYDelta="0%" android:toYDelta="0%"
     android:duration="@android:integer/config_mediumAnimTime" />
</set>

您可以将持续时间更改为短动画时间

you can change the duration to short animation time

android:duration="@android:integer/config_shortAnimTime"

或较长的动画时间

android:duration="@android:integer/config_longAnimTime" 

用法(请注意，您在事务中调用方法的顺序很重要.在调用 .replace、.commit 之前添加动画):

USAGE (note that the order in which you call methods on the transaction matters. Add the animation before you call .replace, .commit):

FragmentTransaction transaction = supportFragmentManager.beginTransaction();
transaction.setCustomAnimations(R.anim.enter_from_right, R.anim.exit_to_left, R.anim.enter_from_left, R.anim.exit_to_right);
transaction.replace(R.id.content_frame, fragment);
transaction.addToBackStack(null);
transaction.commit();
