Как автоматически увеличить автоматически текущее местоположение в карте Google api для Android?

Я включил Google maps Api в андроид-студию, и он также находит текущее местоположение, но я хочу увеличить уровень масштабирования, чтобы я мог более четко и точно просмотреть свое текущее местоположение. Как увеличить уровень масштабирования?

Вы можете найти мой код ниже:

package com.example.umar.testgoogle; import android.location.Location; import android.content.IntentSender; import android.location.Location; import android.os.Bundle; import android.support.v4.app.FragmentActivity; import android.util.Log; import com.google.android.gms.common.ConnectionResult; import com.google.android.gms.common.api.GoogleApiClient; import com.google.android.gms.location.LocationListener; import com.google.android.gms.location.LocationRequest; import com.google.android.gms.location.LocationServices; import com.google.android.gms.maps.CameraUpdateFactory; import com.google.android.gms.maps.GoogleMap; import com.google.android.gms.maps.SupportMapFragment; import com.google.android.gms.maps.model.LatLng; import com.google.android.gms.maps.model.MarkerOptions; public class MapsActivity extends FragmentActivity implements GoogleApiClient.ConnectionCallbacks, GoogleApiClient.OnConnectionFailedListener, LocationListener { public static final String TAG = MapsActivity.class.getSimpleName(); /* * Define a request code to send to Google Play services * This code is returned in Activity.onActivityResult */ private final static int CONNECTION_FAILURE_RESOLUTION_REQUEST = 9000; private GoogleMap mMap; // Might be null if Google Play services APK is not available. private GoogleApiClient mGoogleApiClient; private LocationRequest mLocationRequest; @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_maps); setUpMapIfNeeded(); mGoogleApiClient = new GoogleApiClient.Builder(this) .addConnectionCallbacks(this) .addOnConnectionFailedListener(this) .addApi(LocationServices.API) .build(); // Create the LocationRequest object mLocationRequest = LocationRequest.create() .setPriority(LocationRequest.PRIORITY_HIGH_ACCURACY) .setInterval(10 * 1000) // 10 seconds, in milliseconds .setFastestInterval(1 * 1000); // 1 second, in milliseconds } @Override protected void onResume() { super.onResume(); setUpMapIfNeeded(); mGoogleApiClient.connect(); } @Override protected void onPause() { super.onPause(); if (mGoogleApiClient.isConnected()) { LocationServices.FusedLocationApi.removeLocationUpdates(mGoogleApiClient, this); mGoogleApiClient.disconnect(); } } /** * Sets up the map if it is possible to do so (ie, the Google Play services APK is correctly * installed) and the map has not already been instantiated.. This will ensure that we only ever * call {@link #setUpMap()} once when {@link #mMap} is not null. * <p/> * If it isn't installed {@link SupportMapFragment} (and * {@link com.google.android.gms.maps.MapView MapView}) will show a prompt for the user to * install/update the Google Play services APK on their device. * <p/> * A user can return to this FragmentActivity after following the prompt and correctly * installing/updating/enabling the Google Play services. Since the FragmentActivity may not * have been completely destroyed during this process (it is likely that it would only be * stopped or paused), {@link #onCreate(Bundle)} may not be called again so we should call this * method in {@link #onResume()} to guarantee that it will be called. */ private void setUpMapIfNeeded() { // Do a null check to confirm that we have not already instantiated the map. if (mMap == null) { // Try to obtain the map from the SupportMapFragment. mMap = ((SupportMapFragment) getSupportFragmentManager().findFragmentById(R.id.map)) .getMap(); // Check if we were successful in obtaining the map. if (mMap != null) { setUpMap(); } } } /** * This is where we can add markers or lines, add listeners or move the camera. In this case, we * just add a marker near Africa. * <p/> * This should only be called once and when we are sure that {@link #mMap} is not null. */ private void setUpMap() { mMap.addMarker(new MarkerOptions().position(new LatLng(0, 0)).title("Marker")); } private void handleNewLocation(Location location) { Log.d(TAG, location.toString()); double currentLatitude = location.getLatitude(); double currentLongitude = location.getLongitude(); LatLng latLng = new LatLng(currentLatitude, currentLongitude); //mMap.addMarker(new MarkerOptions().position(new LatLng(currentLatitude, currentLongitude)).title("Current Location")); MarkerOptions options = new MarkerOptions() .position(latLng) .title("I am here!"); mMap.addMarker(options); mMap.moveCamera(CameraUpdateFactory.newLatLng(latLng)); } @Override public void onConnected(Bundle bundle) { Location location = LocationServices.FusedLocationApi.getLastLocation(mGoogleApiClient); if (location == null) { LocationServices.FusedLocationApi.requestLocationUpdates(mGoogleApiClient, mLocationRequest, this); } else { handleNewLocation(location); } } @Override public void onConnectionSuspended(int i) { } @Override public void onConnectionFailed(ConnectionResult connectionResult) { /* * Google Play services can resolve some errors it detects. * If the error has a resolution, try sending an Intent to * start a Google Play services activity that can resolve * error. */ if (connectionResult.hasResolution()) { try { // Start an Activity that tries to resolve the error connectionResult.startResolutionForResult(this, CONNECTION_FAILURE_RESOLUTION_REQUEST); /* * Thrown if Google Play services canceled the original * PendingIntent */ } catch (IntentSender.SendIntentException e) { // Log the error e.printStackTrace(); } } else { /* * If no resolution is available, display a dialog to the * user with the error. */ Log.i(TAG, "Location services connection failed with code " + connectionResult.getErrorCode()); } } @Override public void onLocationChanged(Location location) { handleNewLocation(location); } 

}

Меняться от:

 mMap.moveCamera(CameraUpdateFactory.newLatLng(latLng)); 

чтобы:

 float zoomLevel = 16.0; //This goes up to 21 mMap.moveCamera(CameraUpdateFactory.newLatLngZoom(latLng, zoomLevel)); 

Public static CameraUpdate newLatLngZoom (LatLng latLng, float zoom)

Возвращает CameraUpdate, который перемещает центр экрана на широту и долготу, заданные объектом LatLng, и перемещается к заданному уровню масштабирования.

Параметры latLng объекта LatLng, который содержит требуемую широту и долготу. Масштабируйте желаемый уровень масштабирования в диапазоне от 2.0 до 21.0. Значения ниже этого диапазона установлены в 2.0, а значения над ним равны 21.0. Увеличьте значение для увеличения. Не во всех областях есть плитки с наибольшим уровнем масштабирования. Возвращает CameraUpdate, содержащий преобразование.
