Can I change the Android startActivity() transition animation?

Questions:

I am starting an activity and would rather have a alpha fade-in for startActivity(), and a fade-out for the finish(). How can I go about this in the Android SDK?

How to&Answers:

In the same statement in which you execute finish(), execute your animation there too. Then, in the new activity, run another animation. See this code:

fadein.xml

<set xmlns:android="http://schemas.android.com/apk/res/android" 
     android:fillAfter="true">
     <alpha android:fromAlpha="1.0" 
            android:toAlpha="0.0"
            android:duration="500"/> //Time in milliseconds
</set>

In your finish-class

private void finishTask() {
    if("blabbla".equals("blablabla"){
        finish();
        runFadeInAnimation();
    }
}

private void runFadeInAnimation() {
    Animation a = AnimationUtils.loadAnimation(this, R.anim.fadein);
    a.reset();
    LinearLayout ll = (LinearLayout) findViewById(R.id.yourviewhere);
    ll.clearAnimation();
    ll.startAnimation(a);   
}

fadeout.xml

<set xmlns:android="http://schemas.android.com/apk/res/android"
           android:fillAfter="true">
  <alpha android:fromAlpha="0.0"
         android:toAlpha="1.0"
         android:duration="500"/>
</set>

In your new Activity-class you create a similiar method like the runFadeAnimation I wrote and then you run it in onCreate and don’t forget to change the resources id to fadeout.

Answer:

Starting from API level 5 you can call overridePendingTransition immediately to specify an explicit transition animation:

startActivity();
overridePendingTransition(R.anim.hold, R.anim.fade_in);

or

finish();
overridePendingTransition(R.anim.hold, R.anim.fade_out);

Answer:

See themes on android: http://developer.android.com/guide/topics/ui/themes.html.

Under themes.xml there should be android:windowAnimationStyle where you can see the declaration of the style in styles.xml.

Example implementation:

<style name="AppTheme" parent="...">

    ...

    <item name="android:windowAnimationStyle">@style/WindowAnimationStyle</item>

</style>

<style name="WindowAnimationStyle">
    <item name="android:windowEnterAnimation">@android:anim/fade_in</item>
    <item name="android:windowExitAnimation">@android:anim/fade_out</item>
</style>

Answer:

Use overridePendingTransition

startActivity();
overridePendingTransition(R.anim.fadein, R.anim.fadeout);

fadein.xml

<?xml version="1.0" encoding="utf-8"?>
<set xmlns:android="http://schemas.android.com/apk/res/android">
    <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="500" />
</set>

fadeout.xml

<?xml version="1.0" encoding="utf-8"?>
<set xmlns:android="http://schemas.android.com/apk/res/android">
    <alpha xmlns:android="http://schemas.android.com/apk/res/android"
        android:interpolator="@android:anim/anticipate_interpolator"
        android:fromAlpha="1.0" android:toAlpha="0.0" android:duration="500" />
</set>

Answer:

For fadeIn and fadeOut, only add this after super.onCreate(savedInstanceState) in your new Activity class. You don’t need to create something else (No XML, no anim folder, no extra function).

overridePendingTransition(R.anim.abc_fade_in,R.anim.abc_fade_out);

Answer:

If you always want to the same transition animation for the activity

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    overridePendingTransition(android.R.anim.fade_in, android.R.anim.fade_out);

@Override
protected void onPause() {
    super.onPause();
    if (isFinishing()) {
        overridePendingTransition(android.R.anim.fade_in, android.R.anim.fade_out);
    }
}

Answer:

You can simply create a context and do something like below:-

private Context context = this;

And your animation:-

((Activity) context).overridePendingTransition(R.anim.abc_slide_in_bottom,R.anim.abc_slide_out_bottom);

You can use any animation you want.

Answer:

 // CREATE anim 

 // CREATE animation,animation2  xml // animation like fade out 

  Intent myIntent1 = new Intent(getApplicationContext(), Attend.class);
  Bundle bndlanimation1 =  ActivityOptions.makeCustomAnimation(getApplicationContext(), 
  R.anim.animation, R.anim.animation2).toBundle();
  tartActivity(myIntent1, bndlanimation1);
