    adapter1.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item); 
    spinner2.setAdapter(adapter1); 
    }

做得一样：

spinner_1.setOnItemSelectedListener(new OnItemSelectedListener() { 

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

          if(spinner_1.getSelectedItem().equals("Red")){ 
          { 
            // set adapter to spinner_2 here for "Red" selected 
          } 
          else 
          { 
           // set adapter to spinner_2 for "Red" not selected 
          } 
      }  
      @Override 
      public void onNothingSelected(AdapterView<?> arg0) {     
      } 
});
