  基本應該這樣就要有東西出來，Spinner沒這麼複雜

  Spinner spinner1=null;
  
  spinner1=(Spinner)findViewById(R.id.spn1);
  ArrayAdapter<String> adapterPrice1=new ArrayAdapter<String>(this, R.layout.spinner_sub, String陣列放這邊);
  spinner1.setAdapter(adapterPrice1);
  spinner1.setOnItemSelectedListener(這應該不是問題吧);
   

  另外你的EMU似乎有問題，砍掉重新設定一個，設定完直接Start看看～

   沒細看您的程式碼（Codes）。

  看了您的模擬器出現的紅字，猜想你可以試著：
  1. 等模擬器完全開好再run。

  2. 檢查您的manifest，是不是漏了什麼。

   貼個程式碼上來吧，這樣比較好判斷

  另外也可看看模擬器有沒有甚麼錯誤訊息
