正如您在此處看到的，我的文本視圖正在返回Xxxx。我嘗試過不同的方式來回應，但我確定我的問題在於我的getPersonality（）方法。我能做些什麼來允許我的evaluateType（）方法顯示E，或者我而不是x？我是一個noobie，對不起。 編輯：澄清。我想要我的類型變量來顯示E X或I，具體取決於選擇哪個Spinner項目。我能做些什麼來修復我的變量不會在Android中被更改？
'R.string.True'是一個整數，表示一個字符串的id。 'firstSpinner.getSelectedItem（）。toString（）'是一個字符串。對這些進行比較沒有任何意義。你會知道在問這個問題之前你是否花時間一步一步地運行你的代碼。 – njzk2
