微調觸發另一spinenr

Question

mySpinner.setOnItemSelectedListener(new OnItemSelectedListener() { 
    @Override 
    public void onItemSelected(AdapterView<?> parentView, View selectedItemView, int position, long id) { 
     // my code here, but I don't know how.. 
    } 
} 

我認爲這將是這樣的：

1. 得到mySpinner
2. switch(pos)
3. 更新微調項所選項目的位置？我不知道...

我不知道該怎麼做的最後一步。幫幫我？

Answer 1

嘗試以這種方式

car.setOnItemSelectedListener(new OnItemSelectedListener() { 

     public void onItemSelected(AdapterView<?> arg0, View arg1, 
       int arg2, long arg3) { 
      itemSelected = arg2; 
       // add items to the cardetails spinner's adapter using the itemselected and refresh the adapter using nofifyDataSetChanged() 
     } 

     public void onNothingSelected(AdapterView<?> arg0) { 

     } 
    }); 
    cardetails.setOnItemSelectedListener(new OnItemSelectedListener() { 

     public void onItemSelected(AdapterView<?> arg0, View arg1, 
       int arg2, long arg3) { 

     } 

     public void onNothingSelected(AdapterView<?> arg0) { 

     } 
    }); 

這裏汽車和cardetails是 您需要刷新，這樣的微調也被刷新
