arrayList에서 긴 클릭 제거

Question

긴 클릭 부분에서 제거를 추가 한 후 같은 방법으로 호출 옵션을 추가하려고했지만 작동하지 않았습니다.

두 번째 상자에 코드를 작성하고 (첫 번째 상자는 호출 옵션이 변경되지 않고 작동하지 않음), // 기호로 시도한 변경 사항을 강조 표시했습니다.

이

코드입니다 :

Answer 1

난 당신이 이미 한 것처럼 가장 좋은 방법은 implement a long click listener에 생각 감사드립니다.

그런 다음 사용자가 확인하도록 메시지 대화 상자를 표시하는 것이 좋습니다. 이 방법을 알려 드리겠습니다.

private AlertDialog showCustomDialog(final Activity act, CharSequence title, CharSequence message, CharSequence buttonYes, CharSequence buttonNo, final int selectedIndex) { 
    AlertDialog.Builder customDialog = new AlertDialog.Builder(act); 
    customDialog.setTitle(title); 
    customDialog.setMessage(message); 
    customDialog.setPositiveButton(buttonYes, new DialogInterface.OnClickListener() { 
     public void onClick(DialogInterface dialogInterface, int i) { 
      picURL.remove(selectedIndex); 
     } 
    }); 
    customDialog.setNegativeButton(buttonNo, new DialogInterface.OnClickListener() { 
     public void onClick(DialogInterface dialogInterface, int i) { 
     } 
    }); 
    return customDialog.show(); 
} 

마지막 사항 : 어댑터에서 제거하고 있지만 목록에 없습니다. 어쩌면 이것이 당신의 실수를 일으키는 원인일까요?
