package com.view;

import android.content.Context;
import android.util.AttributeSet;
import android.view.View;
import android.widget.HorizontalScrollView;

public class SyncHorizontalScrollView extends HorizontalScrollView {
    private View mView;
    public SyncHorizontalScrollView(Context context) {
        super(context);
        // TODO Auto-generated constructor stub
    }
    public SyncHorizontalScrollView(Context context, AttributeSet attrs) {
        super(context, attrs);
        // TODO Auto-generated constructor stub
    }
    protected void onScrollChanged(int l, int t, int oldl, int oldt) {
        super.onScrollChanged(l, t, oldl, oldt);
        if (mView != null) {
            mView.scrollTo(l, t);
        }
    }
    public void setScrollView(View view) {
        mView = view;
    }
}

使用方法：

scrollView0=(SyncHorizontalScrollView)findViewById(R.id.scrollView0);
scrollView1=(SyncHorizontalScrollView)findViewById(R.id.scrollView1);
scrollView0.setScrollView(scrollView1);
scrollView1.setScrollView(scrollView0);

如果使用兩個HorizontalScrollView聯動滑動，美觀起見隱藏掉一個的滑動條：android:scrollbars="none"
