Android输入框实时模糊搜索效果的示例代码

Android输入框实时模糊搜索

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

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() {     @Override     protected void onGot(List 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;   }
