This is I think best and easiest approach to achieve animation from center to top:

ivSplashCenter.animate()
            .translationY(-((rlContainer.height - (ivSplashCenter.height * 2)) / 2).toFloat())
            .setInterpolator(AccelerateInterpolator()).duration = 1500

Here, ivSplashCenter is imageview and rlContainer is my root view of XML

NOTE:

One thing you need to understand here is that I am keeping a space from the top edge of the height of the image by ivSplashCenter.height * 2, If you don't want any padding/space at the top then you can just use ivSplashCenter.height

Use animations to do this, for more information about animating views, you could refer to this link and also this

What you are actually looking for in translating a view from the center to the top of the screen, you could use translation animation using the xml.

1.Create a folder anim in the res folder 2.Add a resource file that describes your translation effect like :

<translate xmlns:android="http://schemas.android.com/apk/res/android"
    android:fromXDelta="50%p" android:fromYDelta="50%p" 
    android:toXDelta="50%p" android:toYDelta="0%p" 
    android:duration="1000" 
    android:fillAfter="true" />

You could experiment with the % values.

3.implement this in code like :

translateAnim= AnimationUtils.loadAnimation(getApplicationContext(),
            R.anim.translate_anim);
imageView.startAnimation(translateAnim);

Hope this much of clue suffices!

P.S: You could experiment with fillAfter true or false, so that you could understand their effects better.
