我有 List 女巫包含两个不同的 url我的网址:https://is2-ssl.mzstatic.com/image/thumb/Music111/v4/31/5b/62/315b62fb-3b46-d2ee-5833-be210d3287f7/source/100x100bb.jpg和https://lastfm-img2.akamaized.net/i/u/300x300/5ed371a8b6d03258d597eb661805baee.png我想在我的 AdaperRecyclerView 中切换图标图像(比较 url 的开头),但我的循环不像我想要的那样工作。我的开关图像代码:@Overridepublic void onBindViewHolder(@NonNull SongHolder holder, int possition) { // Source image swicher holder.binding.setModelItem(localArtistNameList.get(possition)); if( Stream.of(localSourceList).anyMatch((s) -> s.startsWith("https://is"))){ holder.binding.sourceIcon.setBackgroundResource(R.drawable.icon_source_itune); }else { holder.binding.sourceIcon.setBackgroundResource(R.drawable.icon_source_lastfm); } holder.binding.executePendingBindings();}@Overridepublic int getItemCount() { return localArtistNameList.size();}我的问题是图标无法更改。我对其进行了调试,并且为了简单起见,我确实打印了屏幕:

使用此代码onBindViewHolder:
holder.binding.setModelItem(localArtistNameList.get(possition));
holder.binding.sourceIcon.setBackgroundResource(localArtistNameList.get(i).startWith("https://is") ? R.drawable.icon_source_itune : R.drawable.icon_source_lastfm);
holder.binding.executePendingBindings();
