java - 如何在 kotlin 或 java 中计算祈祷时间？

问题描述

所以我使用这个类： http ://praytimes.org/code/git/?a=viewblob&p=PrayTimes&h=093f77d6cc83b53fb12e9900803d5fa75dacd110&hb=HEAD&f=v1/java/PrayTime.java 来获取祈祷时间，我想用它我使用位置权限制作的纬度和经度，但是当我更改时区的值时，我并没有给我准确的城市祈祷时间。有没有办法让时区自动工作？所以如果摩洛哥的一个人使用我的应用程序，时区会自动更改为摩洛哥时区，所以祈祷时间会给出准确的时间？同样，如果一个人住在沙特、伊拉克、西班牙……等

提前致谢。

**我的代码有问题**

            Toast.makeText(this, "Turn on location", Toast.LENGTH_LONG).show()
            val intent = Intent(Settings.ACTION_LOCATION_SOURCE_SETTINGS)
            startActivity(intent)
        }
    } else {
        requestPermission()
    }

您可以将 Java 用于示例
