Activity slides out on the left and slides in on the right animation switching

Everyone knows that the default animation switching effect between activities in the Android system is: slide out on the left, slide in on the right. The animation switching effect of pressing the return key is: slide in on the left, slide out on the right. But now mobile phone manufacturers customize their own Rom, such as MI UI and Smartisan OS, etc., which causes the native switching animation of Android to change on different mobile phones. Sometimes we need to change it back to the native state.

This is a picture I stole online. It clearly tells us how Android’s displacement animation transforms:

The following is the specific implementation process:

Write animation file

Create anim directory in the res directory, and then create animation xml files in the directory: out_to_left.xml (exit the animation from the left), in_from_right.xml (enter the animation from the right) out_to_right.xml (exit the animation from the right), in_from_left.xml (enter the animation from the right
) Enter animation on the left)

in_from_left.xml

Write theme files

Open the style.xml file in the values folder, insert a style node into it, and declare a theme.

    <style name="Anim_fade" parent="android:Theme.NoTitleBar">
        <item name="android:windowAnimationStyle">@style/fade</item>
    </style>
   
   
    
    
     
     1
     
     2
     
     3
    
    
   
   
    
    
     
     1
     
     2
     
     3

As you can see, the parent theme of the above theme is @android :style/Theme.NoTitleBar, which inherits most of the attributes from the system theme.
One of the "android:windowAnimationStyle" attributes is customized by us, and the location is also in the style file in the values directory.

    <style name="fade" parent="@android:style/Animation.Activity">
        <item name="android:activityOpenEnterAnimation">@anim/in_from_right</item>
        <item name="android:activityOpenExitAnimation">@anim/out_to_left</item>
        <item name="android:activityCloseEnterAnimation">@anim/in_from_left</item>
        <item name="android:activityCloseExitAnimation">@anim/out_to_right</item>
    </style>

下面重点介绍这其中的几个属性的含义，大家网上搜一下也是可以的，我就直接将我所了解的说一下了：
现在假设有两个Activity A 和 B，在A中可以启动B。同时，A和B的theme属性均设置为上面定义的属性。那么，以上动画的发生时机如下：
（1）当A启动B时，A退出，B进入，A退出时的动画名称为android:activityOpenExitAnimation，动画文件为
R.anim.out_to_left，B进入时的动画名称为android:activityOpenEnterAnimation, 动画文件为R.anim.in_from_right。
（2）当B结束时，B退出，A进入。B退出的动画名称为android:activityCloseExitAnimation, 动画文件为R.anim.out_to_right， A进入时的动画名称为android:activityCloseEnterAnimation, 动画文件为R.anim.in_from_left。

以上全部ok了，我们就能看到想要的效果了。约了基友网上打LOL的，让他等了2个多小时了，估计等会会被骂死，效果图就不贴了，代码已上传，需要的话可以下载看看。

Activity左边滑出，右边滑入的动画切换

转载请注明出处：http://blog.csdn.net/u012301841/article/details/46920809

大家都知道Android系统默认Activity间的动画切换效果为：左边滑出、右边滑入，按返回键的动画切换效果为：左边滑入，右边滑出。但是现在的手机制造商都定制自己的Rom，像MI UI和锤子OS等之类的手机，导致Android原生的切换动画在不同的手机上发生了改变，有时候我们需要让他变回原生的状态。

这是我在网上盗的一张图，它清晰的告诉我们Android的位移动画的变换方式：

下面就是具体的实现过程了：

写动画文件

在 res目录创建anim目录，然后在目录创建动画的xml文件：out_to_left.xml (从左边退出动画) 、in_from_right.xml(从右边进入动画)
out_to_right.xml(从右边退出动画)、in_from_left.xml(从左边进入动画)

in_from_left.xml

    android:fromXDelta="-100%p"

写主题文件

在values文件夹中打开style.xml的文件，在其中插入一个style节点，声明一个主题。

    <style name="Anim_fade" parent="android:Theme.NoTitleBar">
        <item name="android:windowAnimationStyle">@style/fade</item>
    </style>

   3

   3

可以看到，以上主题的父主题是@android :style/Theme.NoTitleBar，就是继承自系统主题的大部分属性。
其中有一个”android:windowAnimationStyle”属性是由我们自定义的，定位的位置同样在values目录下的style文件中。

    <style name="fade" parent="@android:style/Animation.Activity">
        <item name="android:activityOpenEnterAnimation">@anim/in_from_right</item>
        <item name="android:activityOpenExitAnimation">@anim/out_to_left</item>
        <item name="android:activityCloseEnterAnimation">@anim/in_from_left</item>
        <item name="android:activityCloseExitAnimation">@anim/out_to_right</item>
    </style>

The following focuses on the meaning of several of these attributes. You can also search online. I will just tell you what I know: Now suppose there are two Activities A and B, and B can be started
in A. At the same time, the theme attributes of A and B are set to the attributes defined above. Then, the timing of the above animation is as follows:
(1) When A starts B, A exits and B enters. The animation name when A exits is android:activityOpenExitAnimation, the animation file is
R.anim.out_to_left, and the animation name when B enters It is android:activityOpenEnterAnimation, and the animation file is R.anim.in_from_right.
(2) When B ends, B exits and A enters. The animation name of B's exit is android:activityCloseExitAnimation, and the animation file is R.anim.out_to_right. The animation name of A's entry is android:activityCloseEnterAnimation, and the animation file is R.anim.in_from_left.

If all the above is ok, we can see the desired effect. I made an appointment with a gay friend to play LOL online, and I made him wait for more than 2 hours. I guess he will be scolded later, so I won’t post the renderings. The code has been uploaded. You can download it if you need it.
