标签: android sharedpreferences

我正在制作4个玩家的记分卡,用户在页面底部输入4个玩家的分数,当按下+按钮时,刚刚输入的分数将添加到上面的滚动视图中。

插槽编号定义为圆形编号,这样当用户输入相应的EditText为1,12,34,56,78时,应用程序可识别并为插槽= 1添加一行,然后播放器1得分将是12,玩家2是34,P3 = 56,P4 = 78。

然后当用户输入另一个设置如2,23,45,67,89时,它将添加为第2轮,依此类推。 到目前为止,行可以正确添加,插槽号可以是1,2,3等等,但不知道为什么

轮次1的

:老虎机号码正确为1,但上面输入的所有4位球员得分都变为78,

第二轮

:老虎机号码正确为2,但上面输入的所有4位玩家得分都变为89.

答案 0 :(得分:0)

你为每个玩家的分数使用相同的SharedPrefs和key,因此每次连续写入都会被覆盖。

更改为每个播放器加载的首选项,或使密钥唯一。我会做后者,这意味着你也可以放弃每个玩家的商店概念,并做这样的事情:

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();
