ScrollView中ViewPager无法正常滑动的问题

解决方法只需要在接近水平滚动时ScrollView不处理事件而交由其子View(即这里的ViewPager)处理即可，重写ScrollView的onInterceptTouchEvent函数，如下：

<span style="font-size:18px;">package cc.newnews.view;
    
    import android.content.Context;
    import android.util.AttributeSet;
    import android.view.GestureDetector;
    import android.view.GestureDetector.SimpleOnGestureListener;
    import android.view.MotionEvent;
    import android.widget.ScrollView;
    
    public class VerticalScrollView extends ScrollView {
    
    	private GestureDetector mGestureDetector;
    
    	public VerticalScrollView(Context context, AttributeSet attrs) {
    		super(context, attrs);
    		mGestureDetector = new GestureDetector(context, new YScrollDetector());
    	}
    
    	@Override
    	public boolean onInterceptTouchEvent(MotionEvent ev) {
    		return super.onInterceptTouchEvent(ev)
    				&& mGestureDetector.onTouchEvent(ev);
    	}
    
    	class YScrollDetector extends SimpleOnGestureListener {
    
    		@Override
    		public boolean onScroll(MotionEvent e1, MotionEvent e2,
    				float distanceX, float distanceY) {
    			/**
    			 * 如果我们滚动更接近水平方向,返回false,让子视图来处理它
    			 */
    			return (Math.abs(distanceY) > Math.abs(distanceX));
    		}
    	}
    }</span>
