Android-like WeChat-like activity smooth horizontal switching Animation

I can see that overridependingtransition (Android. R. anim. slide_in_left, Android. R. anim. slide_out_right) is used in many podcasts on the Internet,

However, the method should be written in this way after startactivity and before finish;

The results are good, so I used apktool to decompile and view the resource file. I found a word that is "good" and used a large number of XML resource files;

The interface is very simple. You cannot upload the entire demo process. First, paste one: similar to other interfaces, mainly to demonstrate the jump Effect of clicking Next activity and returning:

1. First define the topic of the application node in manifest. xml

<Application
Android: icon = "@ drawable/ic_launcher"
Android: Label = "@ string/app_name"
Android: theme = "@ style/apptheme">

2. apptheme is defined in styles

<Style name = "apptheme" parent = "@ Android: style/theme">
<Item name = "Android: windownotitle"> true </item> <! -- Set no title -->
<Item name = "Android: textsize"> 20sp </item> <! -- Set the text size -->
<Item name = "Android: textcolor"> # f34141 </item>
<Item name = "Android: background"> @ Android: color/background_light </item>
<! -- Set activity switching animation -->
<Item name = "Android: windowanimationstyle"> @ style/activityanimation </item>
</Style>

<! -- Animation style -->
<Style name = "activityanimation" parent = "@ Android: style/animation">
<Item name = "Android: activityopenenteranimation"> @ anim/slide_right_in </item>

<Item name = "Android: activityopenexitanimation"> @ anim/slide_left_out </item>
<Item name = "Android: activitycloseenteranimation"> @ anim/slide_left_in </item>
<Item name = "Android: activitycloseexitanimation"> @ anim/slide_right_out </item>
</STYLE>

3. OK. The entire demo is like this process;
