Android Spinner는 30 초마다 첫 번째 값을 다시 선택합니다.

Question

그래서 ~ 35 값이있는 회 전자가 있습니다. 다섯 번째 항목을 선택하면 선택 될 때 수행 할 작업 (두 번째 회 전자 채우기)이 수행됩니다. 내 문제는 곧 (< 1/2 초) 즉, 첫 번째 회 전자의 옵션 1을 선택하면 두 번째 회 전자의 값을 되돌릴 것입니다. 첫 번째 회 전자의 다섯 번째 항목은 계속 선택되지만 첫 번째 항목이 초당 두 번 선택되는 것처럼 작동합니다.

나는 이것 (거의 아무것도)에서 찾을 수있는 모든 것을 시도했지만 지금까지는 아무 것도 시도하지 못했습니다. 이것은 기본적으로 내 애플 리케이션에 더 나아가에 붙어있다.

전체 코드 : 그냥 첫 번째가 클릭 된 생각 때문에 클릭 된 하나 확인하는 if 문없이 내가 모두 동일 onselected 수신기를 사용하고 있었다

은 수정 된 코드입니다 :

@Override 
public void onItemSelected(AdapterView<?> parent, View view, 
     int pos, long id) { 
    Spinner spnr = (Spinner) parent; 
    Log.i(TAG, "Item selected"); 
    switch(parent.getId()) { 
    case R.id.route_name_spinner: 
    //DecimalFormat df = new DecimalFormat("00##"); 
    int tempPos = pos; 
    Log.i(TAG, ("Position of selected item: " + tempPos)); 
    int routeSelected; 
    if (tempPos < 17) 
     routeSelected = (tempPos + 1); 
    else if (tempPos >= 17 && tempPos < 29) 
     routeSelected = (tempPos + 2); 
    else 
     routeSelected = (tempPos + 3); 
    String temp; 
    if (routeSelected < 10) 
     temp = ("0") + routeSelected; 
    else 
     temp = ("") + routeSelected; 
    String url = "http://www.ltconline.ca/WebWatch/MobileAda.aspx?r=" + temp; 
    new MyInnerClass().execute(url); 
    case R.id.route_direction_spinner: 

    } 

}
