很多开发场景会用到搜索框实时模糊搜索来帮助用户输入内容,如图

Android输入框实时模糊搜索

思路是在EditText 字符变动的时候 弹出ListPopupwindow并更新列表,这样的做法google已经封装为AutoCompleteTextView

用法

 mAutoCompleteTextView.setAdapter(adapter); mAutoCompleteTextView.setFocusable(true); mAutoCompleteTextView.setOnItemClickListener(new AdapterView.OnItemClickListener() { @Override public void onItemClick(AdapterView<?> parent, View view, int position, long id) { } }); 

adapter自定义
Adapter 继承 BaseApdater 需要实现 Filterable 接口

private class SearchAdapter extends BaseAdapter implements Filterable { private Context mContext; public SearchAdapter(Context context) { super(); this.mContext = context; } @Override public int getCount() { if (mSearchCustomEntities == null) { return 0; } else { return mSearchCustomEntities.size(); } } @Override public Object getItem(int position) { if (mSearchCustomEntities == null) { return null; } else { return mSearchCustomEntities.get(position); } } @Override public long getItemId(int position) { return position; } @Override public View getView(int position, View convertView, ViewGroup parent) { ViewHolder holder = null; if (convertView == null) { holder = new ViewHolder(); convertView = LayoutInflater.from(mContext).inflate(R.layout.item_search_custom, null, false); holder.tag = (TextView) convertView.findViewById(R.id.tv_custome_type); holder.name = (TextView) convertView.findViewById(R.id.custom_name); holder.phone = (TextView) convertView.findViewById(R.id.tv_phone); convertView.setTag(holder); } else { holder = (ViewHolder) convertView.getTag(); } holder.phone.setText(mSearchCustomEntities.get(position).phone); holder.name.setText(mSearchCustomEntities.get(position).name); if (mSearchCustomEntities.get(position).type == CustomerType.TEMPORARY_CUSTOMER.getType()) { holder.tag.setVisibility(View.VISIBLE); holder.tag.setText(mContext.getString(R.string.tag_temp)); holder.tag.setTextColor(mContext.getResources().getColor(R.color.customer_temp_txt)); holder.tag.setBackground(mContext.getResources().getDrawable(R.drawable.bg_solid_quote_type_inner_temp)); } else if (mSearchCustomEntities.get(position).type == CustomerType.COLLECTIVE_UNIT.getType()) { holder.tag.setVisibility(View.VISIBLE); holder.tag.setText(mContext.getString(R.string.tag_unit)); holder.tag.setTextColor(mContext.getResources().getColor(R.color.customer_unit_txt)); holder.tag.setBackground(mContext.getResources().getDrawable(R.drawable.bg_solid_quote_type_inner_unit)); } else if (mSearchCustomEntities.get(position).type == CustomerType.OUTER_MOTORCADE.getType()) { holder.tag.setVisibility(View.VISIBLE); holder.tag.setText(mContext.getString(R.string.tag_car)); holder.tag.setTextColor(mContext.getResources().getColor(R.color.customer_car_txt)); holder.tag.setBackground(mContext.getResources().getDrawable(R.drawable.bg_solid_quote_type_inner_car)); } else { holder.tag.setVisibility(View.GONE); } return convertView; } @Override public Filter getFilter() { if (mFilter == null) { mFilter = new ArrayFilter(); } return mFilter; } private class ViewHolder { TextView tag; TextView name; TextView phone; } 

自定义 过滤器

 private class ArrayFilter extends Filter { @Override protected FilterResults performFiltering(CharSequence prefix) { FilterResults results = new FilterResults(); String prefixString = prefix.toString(); //筛选部分 XbcClient.getCustomList(prefixString, new EntitiesObserver<SearchCustomEntity>() { @Override protected void onGot(List<SearchCustomEntity> entities, String msg, int errCode) { if (entities != null && entities.size() > 0) { mSearchCustomEntities.clear(); mSearchCustomEntities.addAll(entities); mSearchAdapter.notifyDataSetChanged(); }else{ if (mSearchCustomEntities!=null & mSearchCustomEntities.size()>0) { mSearchCustomEntities.clear(); mSearchAdapter.notifyDataSetInvalidated(); } } } }); results.values = mSearchCustomEntities; results.count = mSearchCustomEntities.size(); return results; }
