可以

.setOnItemSelectedListener(new OnItemSelectedListener() { 
       @Override 
       public void onItemSelected(AdapterView<?> arg0, View arg1, 
         int position, long arg3) { 
        switch(position) { 
              //Use cases to set Intents 
              } 


       @Override 
       public void onNothingSelected(AdapterView<?> arg0) { 
        // Do Nothing 
       } 
      }); 

Answer 3

只是使用spinner.onItemSelectedListener（新OnItemSelectedListener（））

和onItemSelected（适配器视图适配器视图，查看视图，INT位置，长ID）方法体写你的逻辑根据位置开始新的活动。
