View 滑动冲突处理方法

外部拦截发

在父布局中做处理：

    private int mLastXIntercept;
    private int mLastYIntercept;

    @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:
                if (interceptEvent(ev)) {
                    intercepted = true;
                } else {
                    intercepted = false;
                }
                break;
            case MotionEvent.ACTION_UP:
                intercepted = false;
                break;
            default:
                break;
        }
         mLastXIntercept = x;
         mLastYIntercept = y;
        return intercepted;
    }

    /* 父容器需要当前的点击事件 */
    private boolean interceptEvent(MotionEvent ev) {
        return true;
    }

内部拦截发

子View中做如下处理：

 private int mLastX;
    private int mLastY;

    @Override
    public boolean dispatchTouchEvent(MotionEvent ev) {
        int x = (int) ev.getX();
        int y = (int) ev.getY();
        switch (ev.getAction()) {
            case MotionEvent.ACTION_DOWN:
                getParent().requestDisallowInterceptTouchEvent(true);

                break;
            case MotionEvent.ACTION_MOVE:
                int deltaX = x - mLastX;
                int deltaY = y - mLastY;
                if (dispatchEvent(ev)) {
                    getParent().requestDisallowInterceptTouchEvent(false);
                }
                break;
            case MotionEvent.ACTION_UP:
                break;
            default:
                break;
        }
        mLastX = x;
        mLastY = y;
        return super.dispatchTouchEvent(ev);
    }
     /* 父容器需要当前的点击事件 */
    private boolean dispatchEvent(MotionEvent event) {
        return true;
    }

父容器中做如下处理：

  @Override
    public boolean onInterceptTouchEvent(MotionEvent ev) {
        int action = ev.getAction();
        if (action == MotionEvent.ACTION_DOWN) {
            return false;
        } else {
            return true;
        } 
    }
