Я хочу отфильтровать элемент списка из любой позиции

Question

Я хочу, чтобы фильтр listView был таким образом, что когда пользователь вводит слово/строку в editText, который встречается в элементе listView ... этот элемент должен быть отфильтрован. В нижеприведенном коде поиск начинается с начального символа элемента .... Например: элементы: sachin, dhoni, yuvraj ..... если я ищу v .... фильтр поиска должен показать мне Yuvraj ...

вот мой код:

Answer 1

Добавить этот метод в класса адаптера

public void filter(String charText) { 
      charText = charText.toLowerCase(Locale.getDefault()); 
      searchlocation.clear(); 
      if (charText.length() == 0) 
      { 
       searchlocation.addAll(arraylist); 
      } 
      else 
      { 
       for (SearchLocation wp : arraylist) 
       { 
        if (wp.getLocation().toLowerCase(Locale.getDefault()).contains(charText) || wp.getcity().toLowerCase(Locale.getDefault()).contains(charText)) 
        { 

         searchlocation.add(wp); 
        } 
       } 
      } 
      notifyDataSetChanged(); 

     }} 

---

Добавить это в классе активность

editsearch = (EditText) findViewById(R.id.search); 
     editsearch.addTextChangedListener(new TextWatcher() { 


      @Override 
      public void onTextChanged(CharSequence arg0, int arg1, int arg2, 
             int arg3) { 
       // TODO Auto-generated method stub 
       String text = editsearch.getText().toString().toLowerCase(Locale.getDefault()); 
       adapter.filter(text); 


      } 


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


      } 

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

      } 


     }); 

Answer 2

Просто цикл по всем пунктам и испытания, если они содержат искомый текст.

ArrayList <string> strList = new ArrayList<string>(); 
String search = "h"; 
For each string in dataList 
    If string.contains (search) 
     strList.add (string);
