나는 안드로이드가 처음이므로 실수가 있으면 올바르게 설명하십시오. 드롭 다운 목록에서 항목을 검색하는 방법을 알려주십시오. 감사합니다 !!!

Answer 1

BootstrapDropDown에는 getDropdownData()라는 메서드가 있습니다. 이 메서드는 BootstapDropDown의 항목이 포함 된 String [] 배열을 반환합니다. 배열의 인덱스로 int id를 사용하십시오. 난 당신이 잡아 수 있다고 생각

공공 무효 onItemClick (뷰 그룹 부모,보기 V, INT 아이디) {...}

: '내부 ID가'방법의 매개 변수로 당신에게 전달됩니다 선택한 항목을 코드에 다음 줄을 추가하여 선택하십시오.

String [] dropDownItems = spin.getDropdownData(); String item = dropDownItems [id];

spin.setOnDropDownItemClickListener(new 
    BootstrapDropDown.OnDropDownItemClickListener() { 
    @Override 
    public void onItemClick(ViewGroup parent, View v, int id) { 
    // category=spin.getResources().getResourceName(spin.getId()); 
      String[] dropDownItems = spin.getDropdownData(); 
      String item = dropDownItems[id]; 
    } 
    }); 

// 내가 희망이 도움이 // 실수를
