如何让scrollview在viewpager

Answer 1

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));
}
}
}
