Android uses theme to customize the toggle animation between activity _android

Most of the Android system default activity between the animation switch effect is, the right slide into the left slide; sometimes our needs may be to require all activity to be switched to fade in, and this time you may need to change the default switching style.

Here's the implementation:

First create the Anim folder under the Res folder, and then create the Fade_in.xml and fade_out.xml two animation resources inside

Fade_in.xml

<?xml version= "1.0" encoding= "Utf-8"?> <alpha xmlns:android=
"http://schemas.android.com/apk/res/" Android "
 android:duration=" "
 android:fromalpha=" 0.0 "
 android:interpolator=" @android: anim/ Accelerate_interpolator "
 android:toalpha=" 1.0 "/>

Fade_out.xml

<?xml version= "1.0" encoding= "Utf-8"?> <alpha xmlns:android=
"http://schemas.android.com/apk/res/" Android "
 android:duration=" "
 android:fromalpha=" 1.0 "
 android:interpolator=" @android: anim/ Accelerate_interpolator "
 android:toalpha=" 0.0 "/>

It is then written in the Resources tab in the Styles.xml under the Values folder:

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

 <style name= "Fade" parent= "@android: style/ Animation.activity ">
 <item name=" android:activityopenenteranimation "> @anim/fade_in</item>
 <item name= "android:activityopenexitanimation" > @anim/fade_out</item>
 <item name= "Android : Activitycloseenteranimation "> @anim/fade_in</item>
 <item name=" Android: Activitycloseexitanimation "> @anim/fade_out</item>
 </style>

The final step is to add Android:theme= "@style/anim_fade" in the statement of the activity in Androidmanifest.xml.

<?xml version= "1.0" encoding= "Utf-8"?> <manifest xmlns:android= "http://schemas.android.com/apk/res/" Android "package=" Com.example.customanimationforactivity "android:versioncode=" 1 "android:versionname=" 1.0 "> & LT;USES-SDK android:minsdkversion= "android:targetsdkversion=" "/> <application android:allowBackup=" True "android:icon=" @drawable/ic_launcher "android:label=" @string/app_name "Android:theme=" @android: style/ Theme.notitlebar "> <activity android:name=" com.example.customanimationforactivity.MainActivity "Android: Label= "@string/app_name" android:theme= "@style/anim_fade" > <intent-filter> <action android:name= "Andro Id.intent.action.MAIN "/> <category android:name=" Android.intent.category.LAUNCHER "/> </intent-filter&
 Gt </activity> <activity android:name= ". Appactivity "Android:theme=" @style/anim_fade "> </activity> </application> </manifest>

Post the code for the splash activity:

Package com.example.customanimationforactivity;

Import android.app.Activity;
Import android.content.Intent;
Import Android.os.Bundle;
Import Android.os.Handler;

public class Mainactivity extends activity
{

 private Handler Handler = new Handler ();

 @Override
 protected void onCreate (Bundle savedinstancestate)
 {
 super.oncreate (savedinstancestate);
 Setcontentview (r.layout.activity_main);
 Handler.postdelayed (New Runnable ()
 {
 @Override public
 Void Run ()
 {
 Intent Intent = new Intent (Mainactivity.this, appactivity.class);
 StartActivity (intent);
 Finish ();
 }
 , 1000);

 }
