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：
public void setListViewOnTouchAndScrollListener(final ListView listView1,final ListView listView2){
//设置listview2列表的scroll监听，用于滑动过程中左右不同步时校正
listView2.setOnScrollListener(new OnScrollListener() {
@Override
public void onScrollStateChanged(AbsListView view, int scrollState) {
//如果停止滑动
if(scrollState == 0 || scrollState == 1){
//获得第一个子view
View subView = view.getChildAt(0);
if(subView !=null){
final int top = subView.getTop();
final int top1 = listView1.getChildAt(0).getTop();
final int position = view.getFirstVisiblePosition();
//如果两个首个显示的子view高度不等
if(top != top1){
listView1.setSelectionFromTop(position, top);
}
}
}
}
public void onScroll(AbsListView view, final int firstVisibleItem,
int visibleItemCount, int totalItemCount) {
View subView = view.getChildAt(0);
if(subView != null){
final int top = subView.getTop();
// //如果两个首个显示的子view高度不等
int top1 = listView1.getChildAt(0).getTop();
if(!(top1 - 7 < top &&top < top1 + 7)){
listView1.setSelectionFromTop(firstVisibleItem, top);
listView2.setSelectionFromTop(firstVisibleItem, top);
}
}
}
});
//设置listview1列表的scroll监听，用于滑动过程中左右不同步时校正
listView1.setOnScrollListener(new OnScrollListener() {
@Override
public void onScrollStateChanged(AbsListView view, int scrollState) {
if(scrollState == 0 || scrollState == 1){
//获得第一个子view
View subView = view.getChildAt(0);
if(subView !=null){
final int top = subView.getTop();
final int top1 = listView2.getChildAt(0).getTop();
final int position = view.getFirstVisiblePosition();
//如果两个首个显示的子view高度不等
if(top != top1){
listView1.setSelectionFromTop(position, top);
listView2.setSelectionFromTop(position, top);
}
}
}
}
@Override
public void onScroll(AbsListView view, final int firstVisibleItem,
int visibleItemCount, int totalItemCount) {
View subView = view.getChildAt(0);
if(subView != null){
final int top = subView.getTop();
listView1.setSelectionFromTop(firstVisibleItem, top);
listView2.setSelectionFromTop(firstVisibleItem, top);
}
}
});
