保存應用狀態的問題？

所以我很確定我知道我的問題是什麼，但我不知道如何修復它或解決它的問題......我正在爲一個類製作這個遊戲，現在我試圖保存狀態當用戶點擊後退按鈕或退出應用程序時，應用程序的應用程序。但是當我點擊後退按鈕時，一切都重置爲當你第一次啓動..？保存應用狀態的問題？

這裏是我的類：

        textViewLootResults.setText("Loot: none"); 
       } 
      } 

     } 
    }); /* Ends the button onClickListener */ 
} 
}

現在，我敢肯定，問題出在哪裏我把我所有的私人詮釋的，他們都等於0或任何當你第一次開始播放。我迷茫......

我刪除了我的onPause和活動的onResume因爲他們只是沒有工作，這是代碼之前，我嘗試過這一點。

ŧ他在Android上是相當基本的問題。看看http://stackoverflow.com/questions/151777/saving-activity-state-in-android – Dayerman

所有的變量在運行時都有狀態。如果關閉應用程序，則每個分配的內存以及變量中的值存儲都會丟失。例如，您必須在設備上的SQLite數據庫或xml文件中保存這些內容，以便從中獲取值。

它可幫助瞭解存儲這個教程在Android： Storage Options

你可以像成才保存的onPause（）您的應用程序的值：

Editor editor = getSharedPreferences("myStatusFile", MODE_PRIVATE).edit(); 
editor.clear(); 
editor.putString("string1", string1); 
editor.putInteger("integer1", integer1); 
editor.commit();

和恢復它們的onResume（）有：

SharedPreferences preferences = getSharedPreferences("myStatusFile", MODE_PRIVATE); 
string1 = preferences.getString("string1", null); 
integer1 = preferences.getString("integer1", 0);

好運
