AutoCompletetextview自定義適配器問題

Question

我有一個自動完成文本視圖，顯示sq-lite數據庫的公司名稱。從數據庫記錄是正確的沒有問題。但問題是適配器.adapter是不清楚的，像我第一次搜索的東西和建議顯示比刪除它，並再次鍵入和數據庫中沒有建議，但適配器顯示舊的建議是在最後搜索。 下面我把圖像，以便清楚地確定什麼問題

     super(context, resource, textViewResourceId, fullList);

     return super.getView(position, convertView, parent);

    @Override

      } 

      ArrayList<String> queryResults; 
      if (prefix != null && prefix.length() >= 3 && mOriginalValues != null) { 
       queryResults = autocomplete(prefix.toString()); 
      } else { 
       queryResults = new ArrayList<String>(); // empty list/no suggestions showing if there's no valid constraint 
      } 
      results.values = queryResults;

Answer 1

你必須使用NotifyDataSetChanged更新適配器後，填充新的數據

if(ResponseString.getStcode().equals("0")) { 
            if (name1.size() != 0) { 
             Log.d("ADPTER LIST", name1.toString()); 
             //adapter = new AutoCompleteAdapter(TopupTransfer.this, R.layout.listview_raw,R.id.desc, name1); 
             adapter = new AutoCompleteAdapter2(TopupTransfer.this,R.id.desc, name1); 
             memberView.setAdapter(adapter); 
             adapter.NotifyDatasetChanged(): 
            } 
           } 

Answer 2

這是我在我的情況怎麼實現的，請檢查出來：

public class EmployeeAdapter extends BaseAdapter 

{ 

    Context    context; 
    private ArrayList<Employee> employeelist ; 
    private ArrayList<Employee> arraylist; 



    public EmployeeAdapter(Context context2, ArrayList<Employee> employeeList2) 
    { 
     this.context = context2; 
     this.employeelist = employeeList2; 
     this.arraylist = new ArrayList<Employee>(); 
     this.arraylist.addAll(employeelist); 

    } 

    @Override 
    public int getCount() { 
     // TODO Auto-generated method stub 
     return employeelist.size(); 
    } 

    @Override 
    public Object getItem(int position) { 

     return employeelist.get(position).getEMPLOYEEID(); 
    } 

    @Override 
    public long getItemId(int position) { 
     // TODO Auto-generated method stub 
     return 0; 
    } 

    @Override 
    public View getView(final int position, View convertView, ViewGroup parent) 

    { 

     // TODO Auto-generated method stub 

     LayoutInflater inflater = ((Activity) context).getLayoutInflater(); 
     final ViewHolder holder; 

     if (convertView == null) 
     { 
      convertView = inflater.inflate(R.layout.cursor_row, null); 
      holder = new ViewHolder(); 

      holder.employeename = (TextView) convertView.findViewById(R.id.textcursor); 


      convertView.setTag(holder); 

     } 
     else 
     { 

      holder = (ViewHolder) convertView.getTag(); 
     } 




     holder.empname=employeelist.get(position).getNAME(); 
     holder.empid=employeelist.get(position).getEMPLOYEEID(); 


     holder.employeename.setText(holder.empname); 




     convertView.setOnClickListener(new OnClickListener() 
     { 

      @Override 
      public void onClick(View v) 
      { 


       //context.startActivity(new Intent(context, EmployeeActivity.class)); 
        Intent i = new Intent(context, EmployeeActivity.class); 
       int empid=employeelist.get(position).getEMPLOYEEID(); 

       i.putExtra("emp_id", empid); 
       i.putExtra(Variables.EmployeeType, 1); 

       context.startActivity(i); 




      } 
     }); 


     convertView.setOnLongClickListener(new OnLongClickListener() 
     { 

      @Override 
      public boolean onLongClick(View v) 
      { 
       Log.e("", "Long clickeddddddd"); 

       notifyDataSetChanged(); 

       return false; 
      } 
     }); 
     notifyDataSetChanged(); 

     return convertView; 

    } 

    private class ViewHolder 
    { 
     TextView employeename; 
     String empname; 
     int empid; 


     // TextView FreeItemquantity; 
     // CheckBox check1; 
    } 

    public void filter(String charText) 
    { 
     charText = charText.toLowerCase(Locale.getDefault()); 
     employeelist.clear(); 
     if (charText.length() == 0) 
     { 

      notifyDataSetChanged(); 
      employeelist.addAll(arraylist); 
     } 
     else 
     { 
      for (Employee wp : arraylist) 
      { 
       if (wp.getNAME().toLowerCase(Locale.getDefault()).contains(charText)) 
       { 
        employeelist.add(wp); 
       } 
      } 
      if (employeelist.size() < 1) 
      { 
       Toast.makeText(context, "No Matches Found", Toast.LENGTH_SHORT).show(); 
       //Toast.makeText(context, " No Matches Found ", 1); 
      } 

     } 
     notifyDataSetChanged(); 
    } 

    private Context getContext() { 
     // TODO Auto-generated method stub 
     return null; 
    } 

    /*public ItemClicked getItem(int position){ 

     return items.get(position); 
     }*/ 


}
