update/change animation in Android after loading from xml resource

Issue

How can i update attribute of animation in java code after loading from xml?

I have a rain drop fall animation defined in xml.

<?xml version="1.0" encoding="utf-8"?>

<set xmlns:android="http://schemas.android.com/apk/res/android"  
    android:shareInterpolator="false">
  <translate android:fromYDelta="10%p" 
    android:toYDelta="70%p"
    android:duration="2000" 
    android:repeatCount="1"
    />
   <scale
    android:interpolator="@android:anim/accelerate_decelerate_interpolator"
    android:fromXScale="1.2"
    android:toXScale=".5"
    android:fromYScale="1.2"
    android:toYScale="0.5"
    android:pivotX="50%"
    android:pivotY="50%"
    android:fillAfter="false"
    android:duration="2000" />

after loading this animation

 rainDropAnimation =AnimationUtils.loadAnimation(this, R.anim.cloud_fall_down);

how can i change fromYDelta of animation? basically i have some cloud moving on screen. i wants to show rain if user tap on a cloud. and i don't want to have to many animation resource for different rain drop image,a single animation will serve all drop juts need to change starting point

Solution

Not sure if this could be helpful for anyone BUT I solve my problem using TranslateAnimation.

Here is source code of animation: https://github.com/naveed-ahmad/Android-Game-Pack/blob/feature/UI/src/com/nav/gamepack/shared/WelcomeActivity.java#L192
