滑动冲突

外部拦截法解决滑动冲突

声明成员变量：

/**
	 * 处理滑动冲突的属性
	 */
	private int mLastIntercepX = 0;
	private int mLastIntercepY = 0;

//外部拦截法处理滑动冲突
	public boolean onInterceptTouchEvent(MotionEvent event) {
		boolean intercept = false;
		int x = (int) event.getX();
		int y = (int) event.getY();

		switch (event.getAction()) {
		case MotionEvent.ACTION_DOWN:
			intercept = false;
			break;
		case MotionEvent.ACTION_MOVE:
			int deltaX= (int) (x-mLastIntercepX);
			int deltaY= (int) (y-mLastIntercepY);
			if(Math.abs(deltaX)>Math.abs(deltaY)){//左右滑动
				intercept = true;
			}
			else {//上下滑动，交给子View处理
					intercept = false;

			}
			break;
		case MotionEvent.ACTION_UP:
			intercept = false;
			break;
		}

		mLastIntercepX = x;
		mLastIntercepY = y;

		return intercept;
