我已尝试过所有功能，但仍然无法获得准确的解决方案。

我也尝试了很多其他代码，但是没有人给我完美的解决方案，并且当我滚动listview时，视频位置也会随机变化。请尽可能帮助我
Thanx提前

您可以使用RecyclerView代替。并尝试此代码
RecyclerView rv_featureList;
private View currentFocusedLayout, oldFocusedLayout;
@Override
public void onCreate(Bundle instanceState) {
rv_featuredList.addOnScrollListener(new RecyclerView.OnScrollListener() {
@Override
public void onScrollStateChanged(RecyclerView recyclerView,
int newState) {
super.onScrollStateChanged(recyclerView, newState);
if (newState == AbsListView.OnScrollListener.SCROLL_STATE_IDLE) {
//get the recyclerview position which is completely visible and first
int positionView = ((LinearLayoutManager) recyclerView.getLayoutManager()).findFirstCompletelyVisibleItemPosition();
Log.i("VISISBLE", positionView + "");
if (positionView >= 0) {
if (oldFocusedLayout != null) {
//Stop the previous video playback after new scroll
}
currentFocusedLayout = ((LinearLayoutManager) recyclerView.getLayoutManager()).findViewByPosition(positionView);
//play video
oldFocusedLayout = currentFocusedLayout;
}
}
}
});
}
