首先创建一个实现可过滤的自定义适配器：
public class MyFilterableAdapter extends baseAdapter implements Filterable { private Context context; private List<String> items; private List<String> filteredItems; private ItemFilter mFilter = new ItemFilter(); public MyFilterableAdapter(Context context, List<String> items) { //super(context, R.layout.your_row, items); this.context = context; this.items = items; this.filteredItems = items; } @Override public int getCount() { return filteredItems.size(); } @Override public Object getItem(int position) { return filteredItems.get(position); } @Override public long getItemId(int position) { return position; } @Override public View getView(int position, View convertView, ViewGroup parent) { ViewHolder viewHolder; if (convertView == null) { LayoutInflater inflater = (LayoutInflater) context .getSystemService(Context.LAYOUT_INFLATER_SERVICE); convertView = inflater.inflate(R.layout.row_search_merchant, parent, false); viewHolder = new ViewHolder(); viewHolder.tvTitle = (TextView) convertView.findViewById(R.id.tv_title); convertView.setTag(viewHolder); } else { viewHolder = (ViewHolder) convertView.getTag(); } String location = filteredItems.get(position); if (!location.isEmpty() || viewHolder != null) { viewHolder.tvTitle.setText(location); } return convertView; } public static class ViewHolder { TextView tvTitle; } private class ItemFilter extends Filter { @Override protected FilterResults performFiltering(CharSequence constraint) { String filterString = constraint.toString().toLowerCase(); FilterResults results = new FilterResults(); int count = items.size(); final List<String> tempItems = new ArrayList<>(count); for (int i = 0; i < count; i++) { if (items.get(i).toLowerCase().contains(filterString)) { tempItems.add(items.get(i)); } } results.values = tempItems; results.count = tempItems.size(); return results; } @SuppressWarnings("unchecked") @Override protected void publishResults(CharSequence constraint, FilterResults results) { filteredItems = (ArrayList<String>) results.values; notifyDataSetChanged(); } } public Filter getFilter() { return mFilter; }}而不是创建一个文本监视器
public class MyTextWatcher implements TextWatcher { private MyCustomAdapter lAdapter; public MyTextWatcher(MyCustomAdapter lAdapter) { this.lAdapter = lAdapter; } @Override public void beforeTextChanged(CharSequence s, int start, int count, int after) { } @Override public void onTextChanged(CharSequence s, int start, int before, int count) { } @Override public void afterTextChanged(Editable s) { lAdapter.getFilter().filter(s.toString().toLowerCase()); }}最后将您的TextWatcher添加到您的搜索编辑文本中：
final MyCustomAdapter lAdapter = new MyCustomAdapter(context, items);EditText etSearch = (EditText) view.findViewById(R.id.et_search); etSearch.addTextChangedListener(new SearchTextWatcher(lAdapter));
希望对您有帮助。
