前一段时间写了一个自定义横向滚动条，感觉效果不怎样好（ 

Android 自定义横向滚动条

1、实现效果图

2、实现联动效果的，自定义继承自HorizontalScrollView的SyncHorizontalScrollView滚动条

package com.org.scrollview;import android.content.Context;import android.util.AttributeSet;import android.view.View;import android.widget.HorizontalScrollView;/*** @Description:这个类也是从网上找的参考*/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);//设置控件滚动监听，得到滚动的距离，然后让传进来的view也设置相同的滚动具体if(mView!=null) {mView.scrollTo(l, t);}}/*** 设置跟它联动的view* @param view*/public void setScrollView(View view) {mView = view;}}

3、通用的联动效果的封装类，供需要此效果类继承即可。CustomListScrollManageActivity

4、看怎么继承实现上面类的数据接口MainActivity

package com.org.horizontalscrollview;import java.util.ArrayList;import android.os.Bundle;import android.view.View;import android.widget.AdapterView;import android.widget.Toast;public class MainActivity extends CustomListScrollManageActivity {private ArrayList mList = new ArrayList();@Overrideprotected void onCreate(Bundle savedInstanceState) {super.onCreate(savedInstanceState);getDataSource();super.initView();}    public ArrayList getDataSource(){    for (int i = 0; i < 20; i++) {    int j = i;        StudentItem item1 = new StudentItem(j, "同学A", "男", 18, "高二");        mList.add(item1);        j ++ ;        StudentItem item2 = new StudentItem(j, "同学B", "女", 17, "高三");        mList.add(item2);}    return mList;    }@Overridepublic ArrayList getReadListHeadItems() {ArrayList headItems = new ArrayList();headItems.add("学号");headItems.add("姓名");headItems.add("性别");headItems.add("年龄");headItems.add("年级");return headItems;}@Overridepublic ArrayList getIndexDataArray(int recordIndex) {ArrayList itemsData = new ArrayList();StudentItem item = new StudentItem();item = mList.get(recordIndex);for (int i = 0; i
