从不使用变量t

Question

这个belove是我的load_data java类。我只得到屏幕上显示的变量s，因为＆＃34;变量t从未使用过＆＃34;。有人可以告诉我在哪里可以找到它吗？

Answer 1

const [...butLast, last] = values

很简单，您定义了变量 String t= getResources().getString(R.string.shipping_time, shipping_time.toString()); /* loaddate.setText(Html.fromHtml(t)); */ ，但注释掉了您使用它的位置。这不是错误，这是一个警告。

将来，搜索“t =”或者如果您通过“查找”功能（通常为Ctrl + F）使用通用编码标准“t =”。我不确定这是多么困难，变量是按字母顺序排列的，我确信你的IDE会在它下面出现一个波形。
