Android-通過GPS或者網絡獲取當前位置 kotlin

 

在AndroidManifest中添加

<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION"/> 
<uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION"/>

kotlin代碼

 private fun getLocation(context: Context): Location {
        val locMan = context.getSystemService(Context.LOCATION_SERVICE) as LocationManager
        val checkCameraPermission = ContextCompat.checkSelfPermission(this, Manifest.permission.ACCESS_FINE_LOCATION)
        val checkCallPhonePermission =
            ContextCompat.checkSelfPermission(this, Manifest.permission.ACCESS_COARSE_LOCATION)
        if (checkCallPhonePermission != PackageManager.PERMISSION_GRANTED || checkCameraPermission != PackageManager.PERMISSION_GRANTED) {
            ActivityCompat.requestPermissions(this, permission, 2)
        }
        way.text = "通過GPS定位"
        val location = locMan.getLastKnownLocation(LocationManager.GPS_PROVIDER)
        if (location == null) {
            way.text = "通過網絡定位"
            locMan.getLastKnownLocation(LocationManager.NETWORK_PROVIDER)
        }
        return location
    }

    private fun getGeoByLocation(location:Location){
        longitude.text ="longitude：${location.longitude}"
        latitude.text = "latitude：${location.latitude}"
        val ge =Geocoder(this)
        var addressList =ArrayList<Address>()
        try {
            addressList = ge.getFromLocation(location.latitude,location.longitude,1) as ArrayList<Address>
            detail.text = addressList.toString()
        }catch (e:IOException){
            e.printStackTrace()
        }
        if (addressList.size>0){
            address.text = "${addressList[0].getAddressLine(0)}"
        }
    }

最后直接在onCreate中調用就行了。

 

這種獲取定位方式不適合需要實時監聽位置變化的需求，只適合獲取一次。
