来源：互联网发布：淘宝联盟app怎么返利编辑：程序博客网时间：2024/06/05 06:06

在开发的过程中看到项目有实现两个listview同步滚动的效果，所以就希望跟大家分享一下！！

不用说大家可能也想到在listview的onScrollListener中做一些操作，

现在具体的细节如下：

view source
print?
01public void setListViewOnTouchAndScrollListener(finalListView listView1,finalListView listView2){ 
02          
03            
04         //设置listview2列表的scroll监听，用于滑动过程中左右不同步时校正
05         listView2.setOnScrollListener(newOnScrollListener() { 
06     
07    @Override
08    publicvoid onScrollStateChanged(AbsListView view,int scrollState) {
09     //如果停止滑动
10     if(scrollState ==0 || scrollState ==1){ 
11      //获得第一个子view
12      View subView = view.getChildAt(0);
13       
14      if(subView !=null){
15       finalint top = subView.getTop();
16       finalint top1 = listView1.getChildAt(0).getTop();
17       finalint position = view.getFirstVisiblePosition();
18        
19       //如果两个首个显示的子view高度不等
20       if(top != top1){
21        listView1.setSelectionFromTop(position, top);
22       }
23      } 
24     } 
25      
26    } 
27     
28    publicvoid onScroll(AbsListView view,final intfirstVisibleItem, 
29      intvisibleItemCount, inttotalItemCount) { 
30     View subView = view.getChildAt(0);
31     if(subView !=null){ 
32      finalint top = subView.getTop();
33  
34//      //如果两个首个显示的子view高度不等 
35      inttop1 = listView1.getChildAt(0).getTop();
36      if(!(top1 -7 < top &&top < top1 +7)){ 
37       listView1.setSelectionFromTop(firstVisibleItem, top);
38       listView2.setSelectionFromTop(firstVisibleItem, top);
39      } 
40      
41     } 
42    } 
43   }); 
44         
45       //设置listview1列表的scroll监听，用于滑动过程中左右不同步时校正
46         listView1.setOnScrollListener(newOnScrollListener() { 
47     
48    @Override
49    publicvoid onScrollStateChanged(AbsListView view,int scrollState) {
50    if(scrollState ==0 || scrollState ==1){ 
51      //获得第一个子view
52      View subView = view.getChildAt(0);
53       
54      if(subView !=null){
55       finalint top = subView.getTop();
56       finalint top1 = listView2.getChildAt(0).getTop();
57       finalint position = view.getFirstVisiblePosition();
58        
59       //如果两个首个显示的子view高度不等
60       if(top != top1){
61        listView1.setSelectionFromTop(position, top);
62        listView2.setSelectionFromTop(position, top);
63       }
64      } 
65     } 
66    } 
67     
68    @Override
69    publicvoid onScroll(AbsListView view,final intfirstVisibleItem, 
70      intvisibleItemCount, inttotalItemCount) { 
71     View subView = view.getChildAt(0);
72     if(subView !=null){ 
73      finalint top = subView.getTop();
74      listView1.setSelectionFromTop(firstVisibleItem, top);
75     listView2.setSelectionFromTop(firstVisibleItem, top);
76      
77     } 
78    } 
79   }); 
80}
