如何在没有谷歌的情况下快速获取 GPS 位置更新 fusedLocationClient

Question

我们可以使用 GPS 天线来控制轮询速度吗？就像每 10 秒和每 1 秒一样。假设用电量是可控的。我只是想尽快得到准确的位置。

Answer 1

我们可以使用不是 google API 的 Android 默认 LocationManager 类。

还有华为 Mapkit LocationManager

val locationManager = HuaweiLocationManager(this) locationManager.registerLocationUpdates(onSuccess = { viewModel.updateCurrentLocation(it) })

并以不同的速度订阅更新。

fun registerLocationUpdates(
        interval: Long = 10000,
        onSuccess: ((location: Location?) -> Unit)? = null,
        onFail: ((locationAvailability: LocationAvailability?) -> Unit)? = null
    ) {
        val mLocationRequest = LocationRequest()
        // Set the location update interval (in milliseconds).
        mLocationRequest.interval = interval
        // Set the weight.
        mLocationRequest.priority = LocationRequest.PRIORITY_HIGH_ACCURACY

        // Create location callback
        if (mLocationCallback == null)
            mLocationCallback = createLocationCallback(onSuccess, onFail)

        // Request location update
        mFusedLocationProviderClient.requestLocationUpdates(
            mLocationRequest,
            mLocationCallback,
            Looper.getMainLooper()
        )
            .addOnSuccessListener {
                // Requesting location updates is started successfully.
                LogUtils.d("LocationKit -> Start Location Updates Successfully")
            }
            .addOnFailureListener { exception ->
                // Failed to start location updates.
                LogUtils.d("LocationKit -> Start Location Updates Failed with exception: ${exception.localizedMessage}")
            }
    }
