android activities vertical transition animation

I don't know what is wrong here. Trying to make a vertical animation between two activities. Activity 1 should slide from being visible to bottom. Activity 2 should slide from top to bottom (become visible).

This is what I want enter image description here

my code

overridePendingTransition(R.anim.top_to_visible, R.anim.visible_to_bottom);

top_to_visible.xml

<translate xmlns:android="http://schemas.android.com/apk/res/android"
android:interpolator="@android:anim/accelerate_interpolator"
android:fromYDelta="100%p" android:toYDelta="0%p"
android:duration="300"/>

visible_to_bottom.xml

<translate xmlns:android="http://schemas.android.com/apk/res/android"
android:interpolator="@android:anim/accelerate_interpolator"
android:fromYDelta="0%p" android:toYDelta="-100%p"
android:duration="300"/>

what's wrong here ?

You will need to use anim. First create two xml files and put them in res/anim

top_to_visible.xml

<?xml version="1.0" encoding="utf-8"?>
<translate xmlns:android="http://schemas.android.com/apk/res/android"
    android:duration="@android:integer/config_longAnimTime"
    android:fromYDelta="-100%p"
    android:toYDelta="0" />

visible_to_bottom.xml

 <?xml version="1.0" encoding="utf-8"?>
<translate xmlns:android="http://schemas.android.com/apk/res/android"
    android:duration="@android:integer/config_longAnimTime"
    android:fromYDelta="0%p"
    android:toYDelta="100%p" />

Is it possible that you thought the y axis origin is at the bottom? Because when I just modify the from/to values I get what you want. The 0% of y is at the top. The 0/0 point is at the top left. So based on that you need the "to bottom" to move from 0 to 100% and the "from top to visible" to be -100% to 0%

top_to_visible.xml

<?xml version="1.0" encoding="utf-8"?>
<set xmlns:android="http://schemas.android.com/apk/res/android">
    <translate xmlns:android="http://schemas.android.com/apk/res/android"
        android:duration="300"
        android:fromYDelta="-100%p"
        android:interpolator="@android:anim/accelerate_interpolator"
        android:toYDelta="0%p" />
</set>

and visible_to_bottom

<?xml version="1.0" encoding="utf-8"?>
<set xmlns:android="http://schemas.android.com/apk/res/android">
    <translate xmlns:android="http://schemas.android.com/apk/res/android"
        android:duration="300"
        android:fromYDelta="0%p"
        android:interpolator="@android:anim/accelerate_interpolator"
        android:toYDelta="100%p" />
</set>

Try this for visible_to_bottom.xml animation ..

android:fromYDelta="0%p" android:toYDelta="100%p"

remove the negative sign "-100%p" -> "100%p"
