Android 在自定义列表中搜索自定义getFilter<；对象>；

在自定义arrayAdapter中实现自定义getFilter时遇到问题。尝试了各种代码，但仍然没有成功。这是我的自定义阵列适配器

public class CallSMSAdapter extends RecyclerView.Adapter<RecyclerView.ViewHolder> implements Filterable {
    private final static int TYPE_CALL=1,TYPE_SMS=2;
    private List<Object> callSMSFeed = new ArrayList();
    private List<Object> contactListFiltered;
    // Context is not used here but may be required to
    // perform complex operations or call methods from outside
    private Context context;

    // Constructor
    public CallSMSAdapter(Context context){
        this.context=context;
    }

    public void setCallSMSFeed(List<Object> callSMSFeed){
        this.callSMSFeed = callSMSFeed;
    }

    // We need to override this as we need to differentiate
    // which type viewHolder to be attached
    // This is being called from onBindViewHolder() method
    @Override
    public int getItemViewType(int position) {
        if (callSMSFeed.get(position) instanceof SMS) {
            return TYPE_SMS;
        }
        return -1;
    }

    // Invoked by layout manager to replace the contents of the views
    @Override
    public void onBindViewHolder(final RecyclerView.ViewHolder holder, final int position) {
        int viewType=holder.getItemViewType();

                SMS sms=(SMS)callSMSFeed.get(position);
                ((SMSViewHolder)holder).showSmsDetails(sms);

    }

    @Override
    public int getItemCount(){return callSMSFeed.size();}

    // Invoked by layout manager to create new views
    @Override
    public RecyclerView.ViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
        // Attach layout for single cell
        int layout = 0;
        RecyclerView.ViewHolder viewHolder;
        // Identify viewType returned by getItemViewType(...)
        // and return ViewHolder Accordingly

                layout=R.layout.single_list_item2;
                View smsView = LayoutInflater
                        .from(parent.getContext())
                        .inflate(layout, parent, false);
                viewHolder=new SMSViewHolder(smsView);

        return viewHolder;
    }

    private void setFadeAnimation(View view) {
        AlphaAnimation anim = new AlphaAnimation(0.0f, 1.0f);
        anim.setDuration(500);
        view.startAnimation(anim);
    }

    @Override
    public Filter getFilter() {

        return new Filter() {
            @Override
            protected FilterResults performFiltering(CharSequence charSequence) {

            }

            @Override
            protected void publishResults(CharSequence charSequence, FilterResults filterResults) {

            }
        };
    }

    // Second ViewHolder of object type SMS
    // Reference to the views for each call items to display desired information
    public class SMSViewHolder extends RecyclerView.ViewHolder {

        private TextView senderNameTextView,smsContentTextView, smsTimeTextView;

        public SMSViewHolder(View itemView) {
            super(itemView);
            // Initiate view
            senderNameTextView =(TextView)itemView.findViewById(R.id.pNametxt);
            smsContentTextView =(TextView)itemView.findViewById(R.id.pName2txt);
            smsTimeTextView =(TextView)itemView.findViewById(R.id.pJobProfiletxt);
        }

        public void showSmsDetails(SMS sms){
            // Attach values for each item
            String senderName   =sms.getSenderName();
            String smsContent   =sms.getSmsContent();
            String smsTime     =sms.getSmsTime();
            senderNameTextView.setText(senderName);
            smsContentTextView.setText(smsContent);
            smsTimeTextView.setText(smsTime);
        }
    }
}

我认为错误在于不知道如何获取每个对象中每个数据的值。由于每个对象都由3个值组成，因此我必须能够根据过滤器指示的搜索进行搜索

谢谢。

你没有实现过滤器，你怎么能得到结果？使用一个已经实现了

Filterable

接口的适配器-在99%的情况下，编写自己的

filter

是在重新发明轮子
