How to get animation to work again after complete?

On button click I would like to make an image move either down or right. The issue I am running into is that the movement of the image only occurs once. In onClick() method I am just calling either one of my move methods. Here are the move methods.

private void moveLeftToRight() {
    animation = new TranslateAnimation(0.0f, 200.0f, 0.0f, 0.0f);
    animation.setDuration(1500); // animation duration
    animation.setFillAfter(true);
    iv1.startAnimation(animation); // start animation
}

private void moveUpToDown() {
    animation = new TranslateAnimation(0.0f, 0.0f, 0.0f, 200.0f);
    animation.setDuration(1500); // animation duration
    animation.setFillAfter(true);
    iv1.startAnimation(animation); // start animation
}

I can call either one of these one time for the first time. Thereafter the animation methods do not work. I am wondering if I need to reset or something. Any ideas? Thanks in advance.

When you pass your coordinates to TranslateAnimation those coordinates are relative to 0,0 and not the views coordinates.

To fix this we will get the views coordinates with view.bottom, view.left etc.

Then add the values you'd like to transform by to those values, pass those to TranslateAnimation, and your translation will work as expected.
