How a Translate Animation works: Android

Question

I\'m trying to move a RelativeLayout using TranslateAnimation. Code I have written for performing the same is:

translateAnimation =         


        

Answer 1

The 3rd parameter of the TranslateAnimation constructor you are using is a delta value, so the starting point is calculated like:

currentYPos + startingDeltaY

Since you seem to be passing in a Y value that refers to the location of something on the screen, this delta value won't be correct.

Try using this constructor:

public TranslateAnimation (int fromXType, float fromXValue, int toXType, float toXValue, int fromYType, float fromYValue, int toYType, float toYValue)

Like this:

new TranslateAnimation(Animation.RELATIVE_TO_SELF, 0, Animation.RELATIVE_TO_SELF, 0, Animation.ABSOLUTE, heightOfRootView-excuseContainer.getHeight(), Animation.ABSOLUTE, currentYPoint);
