I'm kind of new to Android. I need to customize animations in my app when the activities open.
I used following code in my application styles.xml
<style name="YourAnimation.Activity" parent="@android:style/Animation.Activity"> <item name="android:windowEnterAnimation">@anim/fade_in</item> <item name="android:windowExitAnimation">@anim/fade_out</item> </style> Then applied the style to a theme, in the same file.
<style name="YourTheme" parent="android:Theme.Translucent"> <item name="android:windowAnimationStyle">@style/CustomAnimationActivity</item> </style> Then added the theme in my AndroidManifest.xml
<application android:allowBackup="true" android:icon="@mipmap/ic_launcher" android:label="@string/app_name" android:theme="@style/YourTheme" > </application> But, when I'm running this, following error occurs.
I think I need to add animation ml files somewhere in my project. but, no idea how to do that. Someone please help me with this.
Thanks in advance. :)
-edit-
Here is the fade_in.xml
<?xml version="1.0" encoding="utf-8"?> <set xmlns:android="http://schemas.android.com/apk/res/android" android:fillAfter="true"> <alpha android:duration="1000" android:fromAlpha="0.0" android:interpolator="@android:anim/accelerate_interpolator" android:toAlpha="1.0"/> </set> Here is the fade_out.xml
<?xml version="1.0" encoding="utf-8"?> <set xmlns:android="http://schemas.android.com/apk/res/android" android:fillAfter="true"> <alpha android:duration="1000" android:fromAlpha="1.0" android:interpolator="@android:anim/accelerate_interpolator" android:toAlpha="0.0"/> </set> Crash Log

In Android Studio:
- right click the res folder.
- New > Android resource directory.
- For Resource type: select anim.
- Press Ok, and you have the anim res folder.
You can then create/include the items for your CustomAnimationActivity as in your styles.
Edit following crash log
java.lang.IllegalStateException: You need to use a Theme.AppCompat theme (or descendant) with this activity.` Just change your styles.xml to extend an AppCompat theme e.g.
<style name="YourTheme" parent="android:Theme.AppCompat.Light"> <item name="android:windowAnimationStyle">@style/CustomAnimationActivity</item> </style> Also, your Activity should probably extend AppCompatActivity (or Activity).

Try to add below xml files in anim folder
fadein.xml
<?xml version="1.0" encoding="utf-8"?> <alpha xmlns:android="http://schemas.android.com/apk/res/android" android:interpolator="@android:anim/accelerate_interpolator" android:fromAlpha="0.0" android:toAlpha="1.0" android:duration="700" /> fadeout.xml
<?xml version="1.0" encoding="utf-8"?> <alpha xmlns:android="http://schemas.android.com/apk/res/android" android:interpolator="@android:anim/decelerate_interpolator" android:zAdjustment="top" android:fromAlpha="1.0" android:toAlpha="0.0" android:duration="700" /> After doing this just add below code in your splash activity (Note. Place this code after finishing your intent)
overridePendingTransition(R.anim.fadein, R.anim.fadeout);
