android Gallery滑动不流畅的解决

import android.content.Context;
import android.util.AttributeSet;
import android.view.KeyEvent;
import android.view.MotionEvent;
import android.widget.Gallery;@SuppressWarnings("deprecation")
public class MyGallery extends Gallery {    public MyGallery(Context context, AttributeSet attrs, int defStyle) {
        super(context, attrs, defStyle);
        // TODO Auto-generated constructor stub
    }    public MyGallery(Context context, AttributeSet attrs) {
        super(context, attrs);
        // TODO Auto-generated constructor stub
    }    public MyGallery(Context context) {
        super(context);
        // TODO Auto-generated constructor stub
    }    // 减慢滑动速度
    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;
    }
}

重写Gallery的几个方法就可以解决了
