Here is a custom transition


ft.setCustomAnimations(

an example: slide_in_left.xml


<?xml version="1.0" encoding="utf-8" ?>
<objectAnimator xmlns:android="http://schemas.android.com/apk/res/android"
    android:interpolator="@android:interpolator/accelerate_decelerate"
    android:valueFrom="-1280"
    android:valueTo="0"
    android:valueType="floatType"
    android:propertyName="x"
    android:duration="2000" />

    android:valueFrom="0"
    android:valueTo="1280"
    android:valueType="floatType"
    android:propertyName="y"
    android:duration="2000" />
