Bottombar: Would be awesome to get the Material animation from the spec sheet.

The spec sheet recommend using this kind of animation.

Would be awesome if you could implement it.

Thanks for your work BTW, it's a great lib.

[roughike]

Will definitely implement that somehow.

And thanks, I really appreciate it.

FragmentTransaction transaction = getSupportFragmentManager().beginTransaction();

// we just would have to create 2 anim xml files with the animation.
transaction.setCustomAnimations(android.R.anim.fade_in, android.R.anim.fade_out);
transaction.replace(R.id.fragmentContainer, fragment);
transaction.commit();

Does somebody already has a similar animation?

Update: See response below

I've tried to get the same transition that we have in the spec. It looks more or less identical! Here my code:

anim/fade_out.xml

<?xml version="1.0" encoding="utf-8"?>
<alpha
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:duration="@android:integer/config_shortAnimTime"
    android:fromAlpha="1"
    android:toAlpha="0"/>

anim/slide_in_up.xml

<?xml version="1.0" encoding="utf-8"?>
<set xmlns:android="http://schemas.android.com/apk/res/android">
    <translate
        android:duration="@android:integer/config_shortAnimTime"
        android:fromYDelta="5%p"
        android:toYDelta="0%p"/>

    <alpha
        android:duration="@android:integer/config_shortAnimTime"
        android:fromAlpha="0"
        android:toAlpha="1"/>
</set>

And in the fragmentManager set:

transaction.setCustomAnimations(R.anim.slide_in_up, R.anim.fade_out);
