错误setBackground动画后查看

Question

我创建了一个CustomView扩展View.创建一些CustomView并使用动画来移动和旋转它们.更改backgroundResource和错误发生后,新的背景不会填写所有CustomView.请看代码:

    clearAnimation();
    AnimationSet animation = new AnimationSet(true);
    TranslateAnimation translateAnimation = new TranslateAnimation(0, destX - srcX, 0, destY - srcY);
    translateAnimation.setInterpolator(new LinearInterpolator());
    translateAnimation.setDuration((long) MGConstant.ANIMATE_DURATION);
    animation.addAnimation(translateAnimation);

    final float finalX = destX;
    final float finalY = destY;

    animation.setAnimationListener(new AnimationListener() {

        public void onAnimationEnd(Animation arg0) {
            clearAnimation();
            setX(finalX);
            setY(finalY);

            RotateAnimation rotateAnimation = new RotateAnimation(0, degrees, Animation.RELATIVE_TO_SELF, 0.5f, Animation.RELATIVE_TO_SELF, 0.5f);
            rotateAnimation.setInterpolator(new LinearInterpolator());
            rotateAnimation.setDuration((long) MGConstant.ANIMATE_DURATION);
            rotateAnimation.setFillAfter(true);
            startAnimation(rotateAnimation);
            resetLayout();

            mMoveStatus = false;
            degree = degrees;

        }

        public void onAnimationRepeat(Animation arg0) {
        }

        public void onAnimationStart(Animation arg0) {
        }
    });


    startAnimation(animation);

和resetLauyout:

     lp = (LayoutParams) getLayoutParams();
    if (lp == null) {
        Log.d(TAG, "FIRST");
        lp = new LayoutParams((int) cardW, (int) cardH);
        lp.leftMargin = (int) mX;
        lp.topMargin = (int) mY;
    } else {
        Log.d(TAG, "LAST");
        lp.leftMargin = (int) mX;
        lp.topMargin = (int) mY;
    }
    setLayoutParams(lp);

请帮我

当您更改布局参数等内容时，请确保您还调用了 View.requestLayout()。但我认为你在这里不需要这个。您所需要的只是以下内容：

    AnimationSet animation = new AnimationSet(true);
    animation.setFillAfter(true);
    TranslateAnimation translateAnimation = new TranslateAnimation(0, destX - srcX, 0, destY - srcY);
    translateAnimation.setInterpolator(new LinearInterpolator());
    translateAnimation.setDuration((long) MGConstant.ANIMATE_DURATION);
    animation.addAnimation(translateAnimation);
    RotateAnimation rotateAnimation = new RotateAnimation(0, degrees, Animation.RELATIVE_TO_SELF, 0.5f, Animation.RELATIVE_TO_SELF, 0.5f);
    rotateAnimation.setInterpolator(new LinearInterpolator());
    rotateAnimation.setDuration((long) MGConstant.ANIMATE_DURATION);
    rotateAnimation.setStartOffset((long) MGConstant.ANIMATE_DURATION);
    animation.addAnimation(rotateAnimation);
    startAnimation(animation);
