我有一个奇怪的问题.我从ListView切换到RecyclerView,我无法刷新或通知我的ListView中的更改.我试着调用Item.this.notifyDataSetChanged();

和其他方法刷新View但它不起作用.

而是滚动时(无论方向如何)刷新RecyclerView.如何更改时如何通知我的RecyclerView？

码：

@Override

public void onBindViewHolder(Ids holder,final int position) {

rowItemClass = (ListViewRow) rowItems.get(position);

Log.e("swag","OYOYOYOYOYO");

if (Globals.isPlaying && Globals.pos == position) {

if (pausedSamePos == true) {

holder.pauseed_play.setVisibility(View.VISIBLE);

holder.playing_pause.setVisibility(View.GONE);

} else {

holder.pauseed_play.setVisibility(View.GONE);

holder.playing_pause.setVisibility(View.VISIBLE);

}

holder.song_currenttime_sb.setActive();

holder.song_duration_sb.setVisibility(View.VISIBLE);

holder.seekbar.setActive();
