How does TranslateAnimation work on Android?

I went through

TranslateAnimation (float fromXDelta, float toXDelta, float fromYDelta, float toYDelta)

but am still confused about how Translate animation works.

Can someone please explain how it works? I read the docs which say

fromXDelta  Change in X coordinate to apply at the start of the animation
toXDelta    Change in X coordinate to apply at the end of the animation
fromYDelta  Change in Y coordinate to apply at the start of the animation
toYDelta    Change in Y coordinate to apply at the end of the animation 

but it is still not clear to me how it works.

EDIT: I have a Button and a LinearLayout without any children. When I am clicking on the Button I want to dynamically generate a TextView and animate that TextView to appear in the LinearLayout. The number of TextViews will depend upon the number of clicks on the Button.
