How to start an Activity with an animation set entirely programmatically [closed]

Question

I am trying to animate the way a new Activity appears. Default is to slide in. I have an animation set that I would like to somehow append to the Intent or the Activity so that it will start when I call startActivity.

The catch is that I need to do this completely programmatically. I cannot declare any XML resources for animations, etc. How would I do this?

Answer 1

Here is some code snippet

startActivity(intent);

overridePendingTransition(R.anim.slide_in_right, R.anim.slide_out_left);

slide_in_right

<set xmlns:android="http://schemas.android.com/apk/res/android">
<translate android:fromXDelta="50%p" android:toXDelta="0"
        android:duration="@android:integer/config_mediumAnimTime"/>
<alpha android:fromAlpha="0.0" android:toAlpha="1.0"
        android:duration="@android:integer/config_mediumAnimTime" />
</set>

slide_out_left

 <set xmlns:android="http://schemas.android.com/apk/res/android">
<translate android:fromXDelta="0" android:toXDelta="-50%p"
        android:duration="@android:integer/config_mediumAnimTime"/>
<alpha android:fromAlpha="1.0" android:toAlpha="0.0"
        android:duration="@android:integer/config_mediumAnimTime" />
</set>
