Android编程开发ScrollView中ViewPager无法正常滑动问题解决方法

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));     }   } }
