Android Alpha Fade in Animation Issue

Question

I have an ImageView element that I create in my code and place inside of my RelativeLayout. I set this image to be Invisible to start off with using the following code:

arrow.setVisibility(View.INVISIBLE);

I then defined a Fade-In Alpha animation via XML:

<set xmlns:android="http://schemas.android.com/apk/res/android"
android:shareInterpolator="false"
android:fillEnabled="true"
android:fillAfter="true"
android:fillBefore="true">

<alpha
    android:fromAlpha="0.0"
    android:toAlpha="1.0"
    android:startOffset="100"
    android:duration="300" />

/set>

To run the animation:

I simply call the following to start the animation

myview.startAnimation(myanimation);

The issue I am seeing is that my animation causes the ImageView to flicker in at full visibility and then go through the animation of alpha 0 to 1. How do I fix this? I can't set the initial alpha value to 0 because the alpha animation is based on percentage and not absolute alpha value. (ex: 0*current value to 1*current value)

Any help would be greatly appreciated.

I think the problem is, with this line of code:

android:fillBefore="true"

Here, Try this code instead, it works for me :

<?xml version="1.0" encoding="UTF-8"?>
<alpha xmlns:android="http://schemas.android.com/apk/res/android"
    android:duration="2000"
    android:fillAfter="true"
    android:fromAlpha="0.0"
    android:toAlpha="1.0" />
