创建为您提供位置的按钮（Android Studio） _Android

知识就是力量，时间就是生命。这篇文章主要讲述创建为您提供位置的按钮（Android Studio）相关的知识，希望能为你提供帮助。
我想创建一个按钮，告诉我我的设备的确切位置，我将其指向MapView并给了我设备的坐标，我不知道如何将动作提供给Button。我试图使用LocationListener，但它给了我一个错误
现在这是我的代码：

public class CameraFragment extends Fragment implements OnMapReadyCallback{ double latitude, longitude; Button myplacebtn; MapView mapView; GoogleMap map; public View onCreateView(LayoutInflater inflater, @Nullable ViewGroup container, @Nullable Bundle savedInstanceState) { View view = inflater.inflate(R.layout.camera_fragment, container, false); myplacebtn = (Button) view.findViewById(R.id.myplacebtn); //Button --get my locationmapView = (MapView) view.findViewById(R.id.mapView); mapView.onCreate(savedInstanceState); //get a MapView mapView.getMapAsync(new OnMapReadyCallback() {@Override public void onMapReady(GoogleMap googleMap) { map = googleMap; // Setting a click event handler for the map map.setOnMapClickListener(new GoogleMap.OnMapClickListener() {@Override public void onMapClick(LatLng latLng) {// Creating a marker MarkerOptions markerOptions = new MarkerOptions(); // Setting the position for the marker markerOptions.position(latLng); setCoordinates.setText(latLng.latitude + " , " + latLng.longitude); latitude = latLng.latitude; longitude = latLng.longitude; // Setting the title for the marker. // This will be displayed on taping the marker markerOptions.title(latLng.latitude + " : " + latLng.longitude); // Clears the previously touched position map.clear(); // Animating to the touched position map.animateCamera(CameraUpdateFactory.newLatLng(latLng)); // Placing a marker on the touched position map.addMarker(markerOptions); } }); map.getUiSettings().setMyLocationButtonEnabled(false); LatLng jerusalem = new LatLng(32.1105435, 34.8683683); CameraUpdate miLocation = CameraUpdateFactory.newLatLngZoom(jerusalem, 11); map.moveCamera(CameraUpdateFactory.newLatLng(jerusalem)); googleMap.animateCamera(miLocation); MarkerOptions markerOptions = new MarkerOptions(); markerOptions.position(jerusalem); if (ActivityCompat.checkSelfPermission(getActivity().getApplicationContext(), android.Manifest.permission.ACCESS_FINE_LOCATION) != PackageManager.PERMISSION_GRANTED & & ActivityCompat.checkSelfPermission(getActivity().getApplicationContext(), android.Manifest.permission.ACCESS_COARSE_LOCATION) != PackageManager.PERMISSION_GRANTED) { // TODO: Consider callingif (Build.VERSION.SDK_INT > = Build.VERSION_CODES.M) { requestPermissions(new String[]{android.Manifest.permission.ACCESS_COARSE_LOCATION, android.Manifest.permission.ACCESS_FINE_LOCATION, Manifest.permission.INTERNET}, MY_REQUEST_INT); } return; } else { googleMap.setMyLocationEnabled(true); }googleMap.getUiSettings().setZoomControlsEnabled(true); } }); }@Override public void onResume() { mapView.onResume(); super.onResume(); }@Override public void onPause() { super.onPause(); mapView.onPause(); }@Override public void onDestroy() { super.onDestroy(); mapView.onDestroy(); }@Override public void onLowMemory() { super.onLowMemory(); mapView.onLowMemory(); }}

如果某人有一个例子，或某些迹象表明我可以开始编写代码，我会非常乐于助人。
答案您可以使用FusedLocationProviderClient和位置更新请求。更多信息：https://developer.android.com/training/location/receive-location-updates

FusedLocationProviderClient locationProviderClient = LocationServices.getFusedLocationProviderClient(this); LocationRequest mLocationRequest = LocationRequest.create() .setPriority(LocationRequest.PRIORITY_HIGH_ACCURACY) .setInterval(TimeUnit.SECONDS.toMillis(10))// 10 seconds .setFastestInterval(TimeUnit.SECONDS.toMillis(1)); // 1 secondLocationCallback locationCallback = new LocationCallback() { @Override public void onLocationResult(LocationResult locationResult) { for (Location location : locationResult.getLocations()) { if (location != null) { // your code here } } } }; if (ActivityCompat.checkSelfPermission(this, Manifest.permission.ACCESS_FINE_LOCATION) != PackageManager.PERMISSION_GRANTED & & ActivityCompat.checkSelfPermission(this, Manifest.permission.ACCESS_COARSE_LOCATION) != PackageManager.PERMISSION_GRANTED) { locationProviderClient.requestLocationUpdates(mLocationRequest, locationCallback, null); }

【创建为您提供位置的按钮（Android Studio）】另外，如果你想摆脱一些请求权限样板代码，我建议你试试RxPermissions库https://github.com/tbruyelle/RxPermissions
