Android视图在开始TranslateAnimation时闪烁

Question

我使用TranslateAnimation移动按钮，它工作正常，但在动画开始之前奇怪的闪烁apear。在短时间内，动画视图移动到更高的位置。之后视图回到正常位置并开始动画。

我使用RelativeLayout并移动7个按钮。

public void moveView(final int rotationType) {
    AnimationSet animationList[] = new AnimationSet[buttonAmount];
    for (int i = 0; i < buttonAmount; i++) {
        AnimationSet animationsSet = new AnimationSet(false);
        animationsSet.setFillAfter(true);
        boolean visible = true;
        boolean hide = false;
        boolean show = false;
        ImageButton button = buttons.get(i);

        int position = i + movementCount;

        if (position < 0) {
            position = getLastButtonId();
        } else if (position > getLastButtonId()) {
            position = position - buttonAmount;
        }
        int cL = getDP(leftCoord.get(position));
        int cB = getDP(bottomCoord.get(position));

        // TODO left right

        if (rotationType == RIGHTBUTTON) {
            position--;
        } else if (rotationType == LEFTBUTTON) {
            position++;
        }

        if (position < 0) {
            position = getLastButtonId();
        } else if (position > getLastButtonId()) {
            position = position - buttonAmount;
        }
        int nL = getDP(leftCoord.get(position));
        int nB = getDP(bottomCoord.get(position));
        int left = cL - nL;
        int bot = cB - nB;
        long time = 1000;

        if (rotationType == LEFTBUTTON) {
            if (cL == getDP(leftArrowLeft) && cB == getDP(leftArrowBottom)) {
                hide = false;
                visible = true;
                show = true;
            }
            if (nL == getDP(leftArrowLeft) && nB == getDP(leftArrowBottom)) {
                hide = false;
                visible = false;
                time = 0;
            }

            if (nL == getDP(rightArrowLeft)
                    && nB == getDP(rightArrowBottom)) {
                hide = true;
            }
        } else

        if (rotationType == RIGHTBUTTON) {
            if (cL == getDP(rightArrowLeft)
                    && cB == getDP(rightArrowBottom)) {
                hide = false;
                visible = true;
                show = true;
            }
            if (nL == getDP(leftArrowLeft) && nB == getDP(leftArrowBottom)) {
                hide = true;
            }

            if (nL == getDP(rightArrowLeft)
                    && nB == getDP(rightArrowBottom)) {
                hide = false;
                visible = false;
                show = false;
                time = 0;
            }
        }

        TranslateAnimation trans = new TranslateAnimation(left, 0, bot, 0);

        final int l = nL;
