水平联滚动怎么实现？

布局水平联动我想实现一个功能上面一个布局是ScrollView里面嵌套一个HorizontalScrollView实现水平滚动在这个布局下面也有一个ScrollView里面嵌套一个HorizontalScrollView的布局实现上下左右滚动我现在想实现的是当上面的布局水平滚动的时候下面的也跟着水平滚动或者下面的水平滚动上面的也跟着水平滚动就是实现联动的效果请问怎么实现 package com.car; import android.app.Activity; import android.os.Bundle; /** * 仿写汽车之家首页效果 */ public class MainActivity extends Activity implements ScrollViewListener, HorizontalScrollViewListener { private MyScrollView scrollView1 = null; private MyScrollView scrollView2 = null; private MyScrollView scrollView3 = null; private MyHorizontalScrollView horizontalScrollView1 = null; private MyHorizontalScrollView horizontalScrollView2 = null; @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_main); scrollView1 = (MyScrollView) findViewById(R.id.scrollview1); scrollView1.setScrollViewListener(this); scrollView2 = (MyScrollView) findViewById(R.id.scrollview2); scrollView3 = (MyScrollView) findViewById(R.id.scrollview3); horizontalScrollView1 = (MyHorizontalScrollView) findViewById(R.id.MyHorizontalScrollView1); horizontalScrollView2 = (MyHorizontalScrollView) findViewById(R.id.MyHorizontalScrollView2); scrollView2.setScrollViewListener(this); } @Override public void onScrollChanged(MyScrollView scrollView, int x, int y, int oldx, int oldy) { if (scrollView == scrollView1) { scrollView2.scrollTo(x, y); } else if (scrollView == scrollView2) { scrollView1.scrollTo(x, y); scrollView3.scrollTo(x,y); } } @Override public void onScrollChanged(MyHorizontalScrollView scrollView, int x, int y, int oldx, int oldy) { if(scrollView == horizontalScrollView1){ horizontalScrollView2.scrollTo(x,y); }else if(scrollView == horizontalScrollView2){ horizontalScrollView1.scrollTo(x,y); } } } 现竖直滚动可以联动但是水平的不能

	package com.car; /** * ScrollViewListener * * @Description: * @Author: pengqiang.zou * @CreateDate: 2015-05-06 15:35 */ public interface ScrollViewListener { void onScrollChanged(MyScrollView scrollView, int x, int y, int oldx, int oldy); }
20分	把所有的HorizontalScrollView加入到一个集合里面，然后监控手势滑动的参数，然后让集合里面的HorizontalScrollView跟着一起滚动。可以看下控件的scrollBy(),scrollTo()这些方法。
20分	如果你是平行滑动的话，为什么不把两个横向的布局放到一个scroll里呢？如果不是平行滑动，就根据你自己的要求计算滑动尺度
	horizontalScrollView1 = (MyHorizontalScrollView) findViewById(R.id.MyHorizontalScrollView1); horizontalScrollView2 = (MyHorizontalScrollView) findViewById(R.id.MyHorizontalScrollView2); horizontalScrollView1.setScrollView(horizontalScrollView2); horizontalScrollView2.setScrollView(horizontalScrollView1);
	上面的代码可以实现2个horizontalScrollView联动
