請幫助我...我不知道我在做什麼錯！Android中的吸氣器和安裝器
我有3個班。
1 - 活性= TelaCadastroRestaurant.java
2 - 實體= Restaurant.java
3 - 方法的類= Metodos.java
問題：當我打電話getNomeRestaurante（）在方法callMandarNuvem（）或ANY其他方法但是pegarvalores（），它不起作用 ...它顯示爲空。
錯誤的打印：http://i.imgur.com/sOcBkUM.png
********************實例***************** **********
如果我創建一個餐廳對象INSIDE方法pegarValores（），並在一個吐司，調用：getNomeRestaurante（）...它是所有正常。但是，如果我在方法pegarValores（）和Toast中創建一個Restaurant對象，請調用：getNomeRestaurante（）... IT SHOWS NULL。
*********************方法的意義*******************
方法 - > inicializaComponentes（）：它引用了Activity的組件。
方法 - > acaoBotoes（）：它處理上的按鈕的點擊
方法 - > pegarValores（）：這意味着，捕值。
方法 - > mandarNuvem（）：這意味着，發送到clound（保存）
方法 - > caixaCerteza（）：它的意思，你確定你想做的事是什麼？
方法 - > taskInProgress（）：它的意思是，加載..等待

請更正代碼在您的文章格式。你能問一個明確的問題嗎？ – kenorb 2015-02-23 21:51:37
@kenorb，我很抱歉，但我不知道如何更具體......我該如何糾正我的帖子？它出什麼問題了？ – lurdes 2015-02-23 22:01:53
Android中的獲取器和設置器像普通Java一樣工作，沒有什麼區別。如果他們返回'null'，那麼這是在類上設置的值。 – m0skit0 2015-02-23 22:49:20
