맞춤 어댑터가있는 Android ListView 검색이 작동하지 않습니다.

Question

ndroid ListView에서 검색을 적용하려고하지만 현재 작동하지 않는 코드는 여기에 있습니다. 여기

final ArrayList<Users> uData = new ArrayList<Users>(); 
listView = (ListView) findViewById(R.id.listView1); 
listView.setAdapter(new CustomListAdapter(this, uData)); 

searchBox.addTextChangedListener(new TextWatcher() { 

      @Override 
      public void onTextChanged(CharSequence cs, int arg1, int arg2, int arg3) { 
       // When user changed the Text 
       ((Filterable) ViewInfo.this.listView.getAdapter()).getFilter().filter(cs); 
      } 

      @Override 
      public void beforeTextChanged(CharSequence arg0, int arg1, int arg2, 
        int arg3) { 
       // TODO Auto-generated method stub 

      } 

      @Override 
      public void afterTextChanged(Editable arg0) { 
       // TODO Auto-generated method stub       
      } 


     }); 

는 사용자 클래스

public class Users implements Serializable 
{ 
private String name; 
private String date; 
private String email; 
private String image; 


public String getName() { 
    return name; 
} 
public void setName(String name) { 
    this.name = name; 
} 
public String getDate() { 
    return date; 
} 
public void setDate(String date) { 
    this.date = date; 
} 
public String getEmail() { 
    return email; 
} 
public void setEmail(String email) { 
    this.email = email; 
} 
public String getimage() { 
    return image; 
} 
public void setimage(String image) { 
    this.image = image; 
} 

이며, 여기에 CustomListAdapter

public class CustomListAdapter extends BaseAdapter { 

    private ArrayList<Users> listData; 
    private LayoutInflater layoutInflater; 
    Users Act = new Users(); 

    public CustomListAdapter(Context context, ArrayList<Users> listData) { 
      this.listData = listData; 
      layoutInflater = LayoutInflater.from(context); 
     } 

    @Override 
     public int getCount() { 
      return listData.size(); 
     } 

     @Override 
     public Object getItem(int position) { 
      return listData.get(position); 
     } 

     @Override 
     public long getItemId(int position) { 
      return position; 
     } 

     public View getView(int position, View convertView, ViewGroup parent) { 
      ViewHolder holder; 
      if (convertView == null) { 
       convertView = layoutInflater.inflate(R.layout.list_row, null); 
       holder = new ViewHolder(); 
       holder.picView = (ImageView) convertView.findViewById(R.id.pic); 
       holder.dateView = (TextView) convertView.findViewById(R.id.date); 
       holder.nameView = (TextView) convertView.findViewById(R.id.name); 
       holder.emailView = (TextView) convertView.findViewById(R.id.email); 

       convertView.setTag(holder); 
      } else { 
       holder = (ViewHolder) convertView.getTag(); 
      } 

      Users act = listData.get(position); 

      holder.picView.setImageBitmap(decodeFile(act.getimage())); 
      holder.dateView.setText(act.getDate()); 
      holder.nameView.setText(act.getName()); 
      holder.emailView.setText(act.getEmail()); 


      return convertView; 
     } 

     static class ViewHolder { 
      ImageView picView; 

      TextView dateView; 
      TextView emailView; 
      TextView nameView; 

     } 
     }

Answer 1

그렇지 사용중인 어댑터를 말하는 것입니다 필터와 함께 작동합니다. ArrayAdapter에서만 작동합니다. 따라서 ArrayAdapter를 사용하거나 데이터 필터링을위한 코드를 작성하십시오.

Answer 2

BaseAdapter을 Filterable으로 변환 할 수 없습니다. Beacause BaseAdapter은 구현되지 않았습니다. Filterable. SimpleAdapter을 사용해보세요.

Answer 3

You may follow below step: 
1) Implements your Base adapter class with filterable class 
2) You will get overriden method "public Filter getFilter()" you can use below code for filtering data 

mListe is the original ArrayList<ContactsPojo> 
mListSearch is the filtered ArrayList<ContactsPojo> 

@Override 
    public Filter getFilter() { 
     Filter filter = new Filter() { 

      @SuppressWarnings("null") 
      @SuppressLint("DefaultLocale") 
      @Override 
      protected FilterResults performFiltering(CharSequence constraint) { 
       FilterResults result = new FilterResults(); 

       if (constraint != null && constraint.length() > 0) { 
        synchronized (this) { 
         mListSearch = new ArrayList<ContactsPojo>(); 
         for (int i = 0; i < mListe.size(); i++) { 
          if ((mListe.get(i).getContactsName().toUpperCase()) 
            .contains(constraint.toString() 
              .toUpperCase())) { 

           ContactsPojo contacts = new ContactsPojo(); 
           contacts.setContactsName(mListe.get(i) 
             .getContactsName()); 
           contacts.setImage(mListe.get(i).getImage()); 
           mListSearch.add(contacts); 
          } 
         } 

        } 

        result.count = mListSearch.size(); 
        result.values = mListSearch; 
       } else if (constraint == null && constraint.length() == 0) { 

        synchronized (this) { 
         result.count = mListe.size(); 
         result.values = mListe; 

        } 

       } 

       return result; 
      } 

      @SuppressWarnings("unchecked") 
      @Override 
      protected void publishResults(CharSequence constraint, 
        FilterResults result) { 
       if (result.count == 0) { 
//     mListe = (ArrayList<ContactsPojo>) mListe; 
        notifyDataSetInvalidated(); 
       } else { 
        mListe = (ArrayList<ContactsPojo>) result.values; 
        notifyDataSetChanged(); 
       } 
      } 

     }; 

     return filter; 
    } 


3) Then you can add this filter to edittext 
    edtSearchContacts.addTextChangedListener(new TextWatcher() { 

      @Override 
      public void onTextChanged(CharSequence s, int start, int before, 
        int count) { 
       mlistAdapter.getFilter().filter(s); 
       mlistAdapter.notifyDataSetChanged(); 
      } 

      @Override 
      public void beforeTextChanged(CharSequence s, int start, int count, 
        int after) { 

      } 

      @SuppressLint("NewApi") 
      @Override 
      public void afterTextChanged(Editable s) { 
       if (s.toString().isEmpty()) { 
        mlistAdapter = new MyListAdapterTwoLine(_con, al3); 
        lvPhnContacts.setAdapter(mlistAdapter); 

       } 
      } 
     }); 
    } 

In afterTextChanged method you will get original items back to listview.
