为什么属性动画移动后仍可点击？

其实最关键的地方是在dispatchTouchEvent中调用了
isTransformedTouchPointInView()判断的

 protected boolean isTransformedTouchPointInView(float x, float y, View child,
            PointF outLocalPoint) {
        final float[] point = getTempPoint();
        point[0] = x;
        point[1] = y;
        transformPointToViewLocal(point, child);
        final boolean isInView = child.pointInView(point[0], point[1]);
        if (isInView && outLocalPoint != null) {
            outLocalPoint.set(point[0], point[1]);
        }
        return isInView;
    }

    /**
     * @hide
     */
    public void transformPointToViewLocal(float[] point, View child) {
        point[0] += mScrollX - child.mLeft;
        point[1] += mScrollY - child.mTop;

        if (!child.hasIdentityMatrix()) {
            child.getInverseMatrix().mapPoints(point);
        }
    }

最终的结果就是判断child.hasIdentityMatrix()的返回值
