Android在Gallery中每次滑动只显示一页

import android.content.Context; import android.util.AttributeSet; import android.view.KeyEvent; import android.view.MotionEvent; import android.widget.Gallery; public class DetialGallery extends Gallery {     public DetialGallery(Context context ,AttributeSet attrSet) {      super(context,attrSet);      // TODO Auto-generated constructor stub     } private boolean isScrollingLeft(MotionEvent e1, MotionEvent e2)    {      return e2.getX() > e1.getX();    } @Override public boolean onFling(MotionEvent e1, MotionEvent e2, float velocityX,    float velocityY) {   // TODO Auto-generated method stub //  return super.onFling(e1, e2, 0, velocityY);//方法一：只去除翻页惯性 //  return false;//方法二：只去除翻页惯性  注：没有被注释掉的代码实现了开始说的2种效果。   int kEvent;   if(isScrollingLeft(e1, e2)){    //Check if scrolling left       kEvent = KeyEvent.KEYCODE_DPAD_LEFT;    }  else{     //Otherwise scrolling right       kEvent = KeyEvent.KEYCODE_DPAD_RIGHT;      }   onKeyDown(kEvent, null);   return true;   } }

亲测可以达到效果，转自http://hi.baidu.com/lvqiyong/blog/item/afbaad3daa102ff454e72390.html
