View half-hidden state sometimes happen in VisibilityAnimationManager

[cdongieux]

There is a little bug in VisibilityAnimationManager:

• grab the handle => the bubble shows up
• release the handle
• grab the handle again at the moment the bubble hide animation starts

Bug => the bubble is in a half-hidden state

To fix this, you have to start the show animation if the hide animation is still running:

    @Override
    public void show() {
        boolean hideIsRunning = hideAnimator.isRunning();
        hideAnimator.cancel();
        if (view.getVisibility() == View.INVISIBLE || hideIsRunning) {
            view.setVisibility(View.VISIBLE);
            updatePivot();
            showAnimator.start();
        }
    }

i have exactly the same problem, this occurs often and easily if we provide the custom animator and set higher duration
