继上篇内部拦截法

需求还是跟上篇一样。只不过这次用外部拦截法来解决；只要在父容器添加如下代码就可以解决了滑动冲突，很简单，套模板就行

 // 分别记录上次滑动的坐标(onInterceptTouchEvent)    private int mLastXIntercept = 0;    private int mLastYIntercept = 0; @Override    public boolean onInterceptTouchEvent(MotionEvent ev) {        boolean intercepted = false;        int x = (int) ev.getX();        int y = (int) ev.getY();        switch (ev.getAction()) {            case MotionEvent.ACTION_DOWN:                intercepted = false;                break;            case MotionEvent.ACTION_MOVE: {                int deltaX = x - mLastXIntercept;                int deltaY = y - mLastYIntercept;                if (Math.abs(deltaX) > Math.abs(deltaY)) {                    intercepted = true;                } else {                    intercepted = false;                }                break;            }            case MotionEvent.ACTION_UP: {                intercepted = false;                break;            }        }        mLastXIntercept = x;        mLastYIntercept = y;        return intercepted;    }

效果如下：
