另外，還需要判斷gps有沒有打開，沒有的話需要引導(dǎo)用戶打開gps

    //判斷gps是否打開
    fun isOpenGps():Boolean =  (context.getSystemService(Context.LOCATION_SERVICE) as 
LocationManager)
        .run {
            isProviderEnabled(LocationManager.GPS_PROVIDER)
        }
    //跳轉(zhuǎn)到打開gps設(shè)置頁(yè)面
    fun openGPSSetting(activity:Activity,requestCode:Int) = activity.startActivityForResult(Intent(Settings.ACTION_LOCATION_SOURCE_SETTINGS),requestCode)

fun openGPSSetting(fragment:Fragment,requestCode:Int) = fragment.startActivityForResult(Intent(Settings.ACTION_LOCATION_SOURCE_SETTINGS),requestCode)
