6,345 PointsThere are a few animations defined below. Create a set that will play the fade and move animations at the same time. Don
help me guys lm stuck
ObjectAnimator fadeInAnimator = ObjectAnimator.ofFloat(button, View.ALPHA, 0, 1);
fadeInAnimator.setDuration(1000);
ObjectAnimator moveUpAnimator = ObjectAnimator.ofInt(button, "top", buttonTop, 16);
moveUpAnimator.setDuration(1000);
ObjectAnimator scaleXAnimator = ObjectAnimator.ofFloat(button, "scaleX", 1.0f, 1.5f);
scaleXAnimator.setDuration(300);
ObjectAnimator scaleYAnimator = ObjectAnimator.ofFloat(button, "scaleY", 1.0f, 1.5f);
scaleYAnimator.setDuration(300);
// Add code below!
private void animate {
ObjectAnimator scalex = ObjectAnimator.ofFloat(fab, "scaleX", 0, 1);
ObjectAnimator scaley = ObjectAnimator.ofFloat(fab, "scaleY", 0, 1);
AnimatorSet scaleFab = new AnimatorSet();
scaleFab.playTogether(scalex, scaley);
int tItleStartValue = titlePanel.getTop();
int titleEndValue =titlePanel.getBottom();
ObjectAnimator animatorTitle = ObjectAnimator.ofInt(titlePanel, "bottom", titleStartValue, titleEndValue);
int trackStartValue = trackPanel.getTop();
int trackEndValue =trackPanel.getBottom();
ObjectAnimator animatorTrack = ObjectAnimator.ofInt(trackPanel, "bottom", trackStartValue, trackEndValue);
AnimatorSet set = new AnimatorSet();
set.playSequentially(animatorTitle, animatorTrack, scaleFab);
}

56,413 PointsThe challenge code is already wrapped in a method so you don't need to specify it. You don't need to create any new animations, just use the ones provided and 1) create a new set 2) with the two animations asked for. Further steps will expand on the answer, but for now this step should only take 2 new lines of code. It looks likely you cut and pasted code from the class project as an answer. That's usually not recommended since the challenges will usually be set up differently and it's better to write the code out.
