I'm having some issues with Android Animations with the ViewAnimator.
Here is my code (yes I know I should do the animations themselves in XML but that isn't the problem):
@Override
public void onActivityCreated(Bundle savedInstanceState) {
super.onActivityCreated(savedInstanceState);
final ViewAnimator animator = (ViewAnimator)getActivity().findViewById(R.id.animator);
Button next = (Button)getActivity().findViewById(R.id.buttonNext);
Button back = (Button)getActivity().findViewById(R.id.buttonBack);
next.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
animator.setInAnimation(inFromBottomAnimation());
animator.setOutAnimation(outToTopAnimation());
animator.showNext();
}
});
back.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
animator.setInAnimation(inFromTopAnimation());
animator.setOutAnimation(outToBottomAnimation());
animator.showPrevious();
}
});
}
private Animation inFromBottomAnimation() {
Animation inFromBottom = new TranslateAnimation(
Animation.RELATIVE_TO_PARENT, 0.0f, Animation.RELATIVE_TO_PARENT, 0.0f,
Animation.RELATIVE_TO_PARENT, +1.0f, Animation.RELATIVE_TO_PARENT, 0.0f
);
inFromBottom.setDuration(1000);
inFromBottom.setInterpolator(new AccelerateInterpolator());
return inFromBottom;
}
private Animation outToTopAnimation() {
Animation outToTop = new TranslateAnimation(
Animation.RELATIVE_TO_PARENT, 0.0f, Animation.RELATIVE_TO_PARENT, 0.0f,
Animation.RELATIVE_TO_PARENT, 0.0f, Animation.RELATIVE_TO_PARENT, -1.0f
);
outToTop.setDuration(1000);
outToTop.setInterpolator(new AccelerateInterpolator());
return outToTop;
}
private Animation inFromTopAnimation() {
Animation inFromTop = new TranslateAnimation(
Animation.RELATIVE_TO_PARENT, 0.0f, Animation.RELATIVE_TO_PARENT, 0.0f,
Animation.RELATIVE_TO_PARENT, -1.0f, Animation.RELATIVE_TO_PARENT, 0.0f
);
inFromTop.setDuration(1000);
inFromTop.setInterpolator(new AccelerateInterpolator());
return inFromTop;
}
private Animation outToBottomAnimation() {
Animation outToBottom = new TranslateAnimation(
Animation.RELATIVE_TO_PARENT, 0.0f, Animation.RELATIVE_TO_PARENT, 0.0f,
Animation.RELATIVE_TO_PARENT, 0.0f, Animation.RELATIVE_TO_PARENT, +1.0f
);
outToBottom.setDuration(1000);
outToBottom.setInterpolator(new AccelerateInterpolator());
return outToBottom;
}
First of all, the animations are delayed. I have to wait half a second before the animation starts. Second, the first animation that runs in the ViewAnimator either does not run at all (just skips to the next view - after half a second wait though because of the first problem) or it runs too quick to notice.
Is there any workaround/fix to these problems?
Seems to have been an Android problem. The problem is a lot less noticeable on Android 4.1.
