android 两个listview同步滚动,2个listview同步滚动

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);
