Kotlin 将比特币价值转换为中本聪价值

Question

//---------------------------------------- --------------------------------------

嗨，这是我的第一个“问题”。我很高兴成为社区的一员。我想获得 Satoshi 硬币的价值（它是 1 BTC 的 100.000.000）我能够找到 1 BTC 的美元价值。基本上，我可以将 1BTC 的美元价值除以 100.000.000 吗？但是如何将值放入 TextView 或 EditText？

Answer 1

java.lang.NumberFormatException：对于输入字符串：“45,586”

表示您的字符串包含，您应该删除，正确格式化字符串。

示例 45,586 相反，您应该将 45586 作为字符串传递
