Recyclerview总是在滚动时重用视图，因此您必须将选定的位置存储到临时arraylist中，然后将条件检查保持在onBindViewHolder中，以确保该特定位置是否已经存在于arraylist中？我更新了你的衣服。在评论中找到以下变化
private List<Occurrence> mDataSet;private Activity activity;//Added here temporary ArrayListprivate ArrayList<String> mSelectedPosition = new ArrayList<String>;public <OccurrencesActivity extends OnOccurrenceSelectedListener> OccurrencesAdapter(OccurrencesActivity occurrencesActivity, List<Occurrence> occurrences) { this.activity = (android.app.Activity) occurrencesActivity; mDataSet = occurrences;}@Overridepublic void onBindViewHolder(final ViewHolder holder, final int position) { //Set ViewTag holder.itemView.setTag(position); //Check everyposition during view binding process if(mSelectedPosition.contains(String.valueOf(position))){ holder.itemView.setBackgroundColor(App.getContext().getResources().getColor(R.color.white)); holder.titleTextView.setTextColor(App.getContext().getResources().getColor(R.color.turquoise)); holder.statusTextView.setTextColor(App.getContext().getResources().getColor(R.color.grey)); holder.dateTextView.setTextColor(App.getContext().getResources().getColor(R.color.grey)); holder.timeTextView.setTextColor(App.getContext().getResources().getColor(R.color.grey)); }else{ holder.itemView.setBackgroundColor(App.getContext().getResources().getColor(R.color.white)); holder.titleTextView.setTextColor(App.getContext().getResources().getColor(R.color.turquoise)); holder.statusTextView.setTextColor(App.getContext().getResources().getColor(R.color.grey)); holder.dateTextView.setTextColor(App.getContext().getResources().getColor(R.color.grey)); holder.timeTextView.setTextColor(App.getContext().getResources().getColor(R.color.grey)); } Occurrence instance = mDataSet.get(position); ... setonClickListener(holder, instance); }private void setonClickListener(final ViewHolder holder, final Occurrence occurrence) { holder.itemView.setonClickListener(new View.onClickListener() { @Override public void onClick(View view) { // Get Position int position = (int) view.getTag(); //Remove SelectedPosition if Already there if(mSelectedPosition.contains(position)) mSelectedPosition.remove(String.valueOf(position)); else mSelectedPosition.add(String.valueOf(position)); notifyDataSetChanged(); //Not sure about this lines occurrence.setSelected(!occurrence.isSelected()); ((OnOccurrenceSelectedListener)activity).onOccurrenceSelected(mDataSet); } }); }
