Answer 1

OnItemSelectedListener에 문제가 있다는 것입니다입니다 선언에서 첫 번째 값을 선택합니다. 첫 번째 호출을 피하려면 다음과 같이하십시오.

int count = 0; 
    @Override 
    public void onCreate(Bundle savedInstanceState) { 
     super.onCreate(savedInstanceState); 
     setContentView(...); 
     ... 
     spinner.setOnItemSelectedListener(new OnItemSelectedListener() { 
      @Override 
      public void onItemSelected(AdapterView<?> arg0, View arg1, 
        int arg2, long arg3) { 
       if(count>0) { 
        // do what you want on item selection 
       } else { 
        count++; 
       } 
      } 

      @Override 
      public void onNothingSelected(AdapterView<?> arg0) { 
      } 
     }); 
    }
