리스트 뷰가 스크롤 될 때 editText의 값을 잃습니다.

Question

안녕하세요 누구든지 나를 도와 줄 수 있습니까? 내 목록보기를 채우기 위해 사용자 지정 어댑터를 사용하고 있습니다. 내 listview에는 editText를 보유하는 해시 맵이 있습니다. 내 문제는 editText에 내용을 입력하고 listview를 스크롤하면 editText의 내용이 손실된다. 내가 지금 무엇을해야합니까? 아래 코드는 내 코드를 보여줍니다.

hashMap을 classVariable로 사용하십시오. 태그

editTxt.setTag(IdNo); 

처럼 글고 당신이 그것을 스크롤 할 때 뷰를 다시로드

if(SavedData.containsKey(IdNo)) { 
    editTxt.setText(SavedData.get(IdNo).toString()); 

} 

editTxt.addTextChangedListener(new TextWatcher() { 

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

      public void afterTextChanged(Editable s) { 

       //Save your Changed Text to HashMap using tag of edittext 
       SavedData.add(editTxt.getTag(),s.toString()); 

      } 
      public void onTextChanged(CharSequence s, int start, int before, 
        int count) { 

      } 
     });
