获取值和微调点击

Question

时选择spinner1那么其对应的数据会自动填充在spinner2

下面我得到的spinner1和微调2两个数据其特定的关键是XML格式的数据获取从URL则─

<a:Pair> 
<a:FromID>01</a:FromID>  <---This should Toast----> 
<a:FromName>INDIA</a:FromName><---On selecting this from spinner-------> 
<a:ToID>40</a:ToID> 
<a:ToName>TURKEY</a:ToName> 
</a:Pair> 

<a:Pair> 
<a:FromID>10</a:FromID> 
<a:FromName>USA</a:FromName> 
<a:ToID>01</a:ToID> 
<a:ToName>INDIA</a:ToName> 
</a:Pair> 

<a:Pair> 
<a:FromID>19</a:FromID> 
<a:FromName>CHINA</a:FromName> 
<a:ToID>10</a:ToID> 
<a:ToName>USA</a:ToName> 
</a:Pair> 

<a:Pair> 
<a:FromID>40</a:FromID> 
<a:FromName>TURKEY</a:FromName> 
<a:ToID>01</a:ToID> 
<a:ToName>INDIA</a:ToName> 
</a:Pair> 

</Result> 
</Response> 

但事实是，如果spinner1数据是美国选择那么我想敬酒其对应的ID我。 E-10 ...我将在今后的使用传递到下一个活动也

我下面的代码工作正常，我只想当spinner1选择它的ID从XML数据被选择，如果spinner2那么其相应的ID也应该敬酒。

我无法ID传递给

Answer 1

您可以创建单独的行动被填充在微调和烤面包相应的数据ID在每个这样的微调上

spinner.setOnItemSelectedListener(new AdapterView.OnItemSelectedListener() { 
      @Override 
      public void onItemSelected(AdapterView<?> parent, View view, int position, long id) { 
        // Show your toast for Spinner 1 
        from_adapter2.notifyDataSetChanged();// Changed 
       } 
      } 

      @Override 
      public void onNothingSelected(AdapterView<?> parent) { 

      } 
     }); 

spinner2.setOnItemSelectedListener(new AdapterView.OnItemSelectedListener() { 
      @Override 
      public void onItemSelected(AdapterView<?> parent, View view, int position, long id) { 
        // Show your toast for Spinner 2 
       } 
      } 

      @Override 
      public void onNothingSelected(AdapterView<?> parent) { 

      } 
     });
