android記分卡 - 共享首選項和顯示

Question

我現在正在研究4名玩家的記分卡，用戶在頁面底部輸入4名玩家的分數，當按下+按鈕時，剛輸入的分數將添加到上面的滾動視圖。

槽號被定義爲輪數，使得當用戶輸入相應的EditText作爲1,12,34,56,78時，應用可以識別並添加slot = 1的行，然後玩家1得分將是12，玩家2將是34，P3 = 56，P4 = 78.

然後當用戶輸入另一個像2,23,45,67,89這樣的設置時，它將添加爲第2回合等等。 到目前爲止該行可以正確添加，插槽號可以是1,2,3等，但不知道爲什麼

第1輪：插槽號正確爲1，但所有4球員得分作爲輸入上述成爲78，

圓2：槽號正確的，因爲2，但最重要的4個播放器分數作爲輸入成爲89

Answer 1

您使用的每一樣SharedPrefs和關鍵球員的得分，所以每次連續寫入都會被忽略。

要麼更改爲每個玩家加載的首選項，要麼使密鑰唯一。我會做後者，這意味着你也可以爲每個玩家拋棄一個商店的概念，並且做這樣的事情：

scoreStore = getSharedPreferences("scores", MODE_PRIVATE); 

... 

scoreEditor = scoreStore.edit(); 
scoreEditor.putString("p1score", p1score); 
scoreEditor.putString("p2score", p2score); 
scoreEditor.putString("p3score", p3score); 
scoreEditor.putString("p4score", p4score); 
scoreEditor.apply();
