Google maps or yandex map

I just started studying Android, and I wanted to create a little apple cator that would work with an online map.
I've got a question about how to choose and of course tried both options and couldn't stop them.
Which advice, and if it's not difficult to give, please, a reference to an up-to-date android Studio map set...

I don't see in which case you could change your markers array, if in the backend you always do the same query. But suppose you call your function downloadUrl on several occasions and you get different results.First, you should have a variable marker_array accessible from outside functions.Second, after going through the XML and creating each marker, add it to marker_arrayThird, before we call downloadUrl several existing markersvar marker_array=[]; function initMap() { ... codigo ... downloadUrl('complemento_audio.php', function(data) { var markers = xml.documentElement.getElementsByTagName('marker'); Array.prototype.forEach.call(markers, function(markerElem) { ... más código ... var marker = new google.maps.Marker({ map: map, position: point, icon: icon1, draggable: true, }); marker_array.push(marker) // AQUI LO METES EN EL ARRAY }); } function downloadUrl(url, callback) { // Antes de pedir un nuevo XML, // procedo a vaciar mis markers existentes while(marker_array.length) { var marker = marker_array.pop(); marker.setMap(null); } ... código ... }

The error message is clear. The builder MediaController() It requires a Context type argument and what you're going through is a Fragment.All you need to do is replace MediaController(this) for MediaController(requireActivity())Bonus tip: The proper way to get a ViewModel in kotlin isprivate val viewModel: BuscarViewModel by viewModels() bonus tip 2: Instead of retrieving so many times "videoView" you should use a https://kotlinlang.org/docs/reference/scope-functions.html videoView.run { setMediaController(mediaController) setVideoURI(Uri.parse("https://video.mp4")) requestFocus() start() }

Occupy splitting the friend screenHere you will apply to define "weights" with the layout_weight property in your view, assuming the following example, in which we need our view below to always occupy 50% of the screen and this positioned at the bottom, but we also need to add another 2 views, which one occupies 30% of the screen and the second the 20%. If we take into account the total screen as the 1 , we assign a value of .50 to always occupy 50% of the screen our view : <WebView android:layout_width="match_parent" android:layout_height="0dp" android:layout_weight=".50" android:id="@+id/webView" android:layout_alignParentBottom="true" /> and so with the other views, one will occupy 30% (assigned .30) and the other 20% (assigned .20):<?xml version="1.0" encoding="utf-8"?> <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="match_parent" android:layout_height="match_parent" android:orientation="vertical"> <Button android:layout_width="match_parent" android:layout_height="0dp" android:layout_weight=".30" android:text="Vista 1" /> <Button android:layout_width="match_parent" android:layout_height="0dp" android:layout_weight=".20" android:text="Vista 2" /> <WebView android:layout_width="match_parent" android:layout_height="0dp" android:layout_weight=".50" android:id="@+id/webView" android:layout_alignParentBottom="true" /> </LinearLayout> We can ensure that the views will have the percentage specified on the screen and your decide where to get the result.I hope my popcorn friend

Where you're calling. <Map/>:(1) Create an empty object googleMap (name of your choice):(2) Give it to you. this.googleMap Map in propsexport default class MapParent extends ... { googleMap = {} render() { return ( <Map // ваши другие props googleMap={this.googleMap} /> ) } } Then your map will be available through this.googleMapP.S: in this.googleMap The object of the map falls not immediately, but only after a while.Accordingly, the location of the centre: this.googleMap.map.getCenter()

No, it's not normal.Indeed, imagine that would be possible:unordered_map<int, shared_ptr<B> > bs; unordered_map<int, shared_ptr<A> > as = some_special_cast< unordered_map<int, shared_ptr<A> > >(bs); Then you could. add Class A Total as (sighs)shared_ptr<A> pa(new A()); as[0] = pa;) I mean, bs! And that doesn't right.You. You can. try. reinterpret_castbut it's a very low-level hack.Here's another topic: http://www.parashift.com/c++-faq-lite/parkinglot-of-car-vs-vehicle.html ♪There are so-called NETs. quarantine Interfaces: With a container of objects of a given class, you can have read-only view it as a container of basic class elements. But there's no C++.Perhaps your problem can be solved can be solved by the templates. Tell me about yours. present A task.

Using your code I see it works smoothly I think stopping the app completely and reinstalling it will work properly.Anything you can change the code for this other (but yours is equally functional)void main() => runApp(MyApp()); class MyApp extends StatefulWidget { @override _MyAppState createState() => _MyAppState(); } class _MyAppState extends State<MyApp> { Completer<GoogleMapController> _mapController = Completer(); final LatLng _center = const LatLng(45.521563, -122.677433); @override Widget build(BuildContext context) { return MaterialApp( home: Scaffold( appBar: AppBar( title: Text('Maps Sample App'), backgroundColor: Colors.green[700], ), body: GoogleMap( onMapCreated:(mapController) { _mapController.complete(mapController); }, initialCameraPosition: CameraPosition( target: _center, zoom: 11.0, ), ), ), ); } }

About the first question you can use the same key, just have to check if API Directions is enabled in your account( https://console.cloud.google.com/ ) and if your key is not limited to a specified API.On the second question, you can already advance using these links. https://github.com/googlemaps/google-maps-services-js https://developers.google.com/maps/documentation/directions/start

View rowView_1 = convertView; View rowView_2 = convertView; I don't know. rowView_2=rowView_1and type ViewHolder_form_1And you're trying to lead him to a type. ViewHolder_form_2♪if (rowView_2 == null) {...} else { (ViewHolder_form_2) rowView_2.getTag(); } Here you are. rowView_2 No. nullIt doesn't matter. rowView_1And so is the type of flow there, too.

getCacheDir() returns an object that describes the absolute path to folders with cash and mkdirs() creates a folder rather than a file.You need to make a way to the file. For example:fileName = File (this.getCacheDir(), "quest.txt");

It's just gidlines for Material Design. They don't belong to Android, but to design in general. Besides, there's no Slider class in Android. The analogue is called SeekBar. You can try to do a theme for him, or you can make it based on your class, which will look like what's on the picture.
