"Chase" current view off screen with "Next" view in android (overridePendingTransition)

Question

My current android application has a requirement to have the "Next" screen slide up from the bottom of the screen as the current view slides out from the top. I can achieve this effect with anim and overridePendingTransition. However i want the "Next" screen to slide up faster from the bottom than than the current screen is sliding out the top of the screen. What attributes (and values) do i require in my animation xml files to achieve this effect?

Answer 1

This will slide the next screen in from the bottom to the top and the current screen out from the top and 25% up making the next screen slide over the current screen.

slide_in_bottom.xml

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

slide_out_top.xml

<?xml version="1.0" encoding="utf-8"?>
<translate xmlns:android="http://schemas.android.com/apk/res/android"
    android:duration="@android:integer/config_mediumAnimTime"
    android:fromYDelta="0"
    android:toYDelta="-25%p" />
