Android View confused with X, left, and transitionX

[Pu Yongming]

Hi all,

I am very confused and can't understand the necessary of the x, left property in class View.

I searched the internet and found:  x = getLeft() + getTransitionX();

why need some thing like that.

I think a single x or left is enough for a view system to layout, measure and draw.

can someone explian for me?

BR,

The "x = getLeft" is for telling system that "X is left" and the " getTransitionX()" is to say that it is able to move, and that its not locked in place.

thanks, but why can't there be a single X, no left, no translation. if you move a view, just change the x. this is much simpler.

Alright, so i explained the first part, it is trying to say: "I want the X to be the same as left, now I want it to change or in other words Transistion". I know that it would be simpler, but that is the way it is.
