If you want to implement this without XML you could do so as follows

final float growTo = 1.2f;
final long duration = 1200;

ScaleAnimation grow = new ScaleAnimation(1, growTo, 1, growTo, 
                                         Animation.RELATIVE_TO_SELF, 0.5f,
                                         Animation.RELATIVE_TO_SELF, 0.5f);
grow.setDuration(duration / 2);
ScaleAnimation shrink = new ScaleAnimation(growTo, 1, growTo, 1,
                                           Animation.RELATIVE_TO_SELF, 0.5f,
                                           Animation.RELATIVE_TO_SELF, 0.5f);
shrink.setDuration(duration / 2);
shrink.setStartOffset(duration / 2);
AnimationSet growAndShrink = new AnimationSet(true);
growAndShrink.setInterpolator(new LinearInterpolator());
growAndShrink.addAnimation(grow);
growAndShrink.addAnimation(shrink);
thumbLike.startAnimation(growAndShrink);

Of course, you could also use NineOldAndroids and use the new animation methods.

I think your original error is this line, it removes the animation you just started from the view again.

thumbLike.setAnimation(null);
