Googleマップで作業していましたが、私自身のアプリケーションで2つの場所（私の現在地と目的地の場所） google mapsアプリケーション。だから私にこれを行う方法を提案してください。今まで私は、Googleマップの統合を完了し、私の現在の位置にズームして、目的地lat-longにマーカーを配置しました。私のアプリケーション内の2つの場所間のGoogleマップの運転方法
私のjavaファイル：
public class GoogleMapActivity extends FragmentActivity implements
OnMapReadyCallback, GoogleMap.OnMarkerClickListener, GoogleApiClient.ConnectionCallbacks, GoogleApiClient.OnConnectionFailedListener {
Location mLastLocation;
GoogleApiClient mGoogleApiClient;
private GoogleMap mMap;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_google_map);
SupportMapFragment mapFragment =
(SupportMapFragment) getSupportFragmentManager().findFragmentById(R.id.map);
mapFragment.getMapAsync(this);
Log.d("Tag", "in onc control in try");
buildGoogleApiClient();
}
protected void onStart() {
mGoogleApiClient.connect();
super.onStart();
}
protected void onStop() {
mGoogleApiClient.disconnect();
super.onStop();
}
protected synchronized void buildGoogleApiClient() {
mGoogleApiClient = new GoogleApiClient.Builder(this)
.addConnectionCallbacks(this)
.addOnConnectionFailedListener(this)
.addApi(LocationServices.API)
.build();
mGoogleApiClient.connect();
}
@Override
public void onConnected(@Nullable Bundle bundle) {
if (ActivityCompat.checkSelfPermission(this, Manifest.permission.ACCESS_FINE_LOCATION) != PackageManager.PERMISSION_GRANTED && ActivityCompat.checkSelfPermission(this, Manifest.permission.ACCESS_COARSE_LOCATION) != PackageManager.PERMISSION_GRANTED) {
// TODO: Consider calling
// ActivityCompat#requestPermissions
// here to request the missing permissions, and then overriding
// public void onRequestPermissionsResult(int requestCode, String[] permissions,
// int[] grantResults)
// to handle the case where the user grants the permission. See the documentation
// for ActivityCompat#requestPermissions for more details.
return;
}
mLastLocation = LocationServices.FusedLocationApi.getLastLocation(
mGoogleApiClient);
if (mLastLocation != null) {
Log.d("TAG","lat"+mLastLocation.getLatitude());
Log.d("TAG","lng"+mLastLocation.getLongitude());
ToastHelper.blueToast(getApplicationContext(), "location is " + mLastLocation.getLatitude() + " " + mLastLocation.getLongitude());
mMap.animateCamera(CameraUpdateFactory.newLatLngZoom(new LatLng(mLastLocation.getLatitude(), mLastLocation.getLongitude()), 12.0f));
LatLng destination = new LatLng(14.880499, 79.988847);
mMap.addMarker(new MarkerOptions().position(destination).title("Destination"));
}
else {
Log.d("TAG","mLastLocation is null");
}
}
@Override
public void onConnectionSuspended(int i) {
}
/**
* Called when the map is ready.
*/
@Override
public void onMapReady(GoogleMap map) {
mMap = map;
if (ActivityCompat.checkSelfPermission(this, Manifest.permission.ACCESS_FINE_LOCATION) != PackageManager.PERMISSION_GRANTED && ActivityCompat.checkSelfPermission(this, Manifest.permission.ACCESS_COARSE_LOCATION) != PackageManager.PERMISSION_GRANTED) {
// TODO: Consider calling
// ActivityCompat#requestPermissions
// here to request the missing permissions, and then overriding
// public void onRequestPermissionsResult(int requestCode, String[] permissions,
// int[] grantResults)
// to handle the case where the user grants the permission. See the documentation
// for ActivityCompat#requestPermissions for more details.
return;
}
mMap.setMyLocationEnabled(true);
}
/**
* Called when the user clicks a marker.
*/
@Override
public boolean onMarkerClick(final Marker marker) {
// Retrieve the data from the marker.
// Return false to indicate that we have not consumed the event and that we wish
// for the default behavior to occur (which is for the camera to move such that the
// marker is centered and for the marker's info window to open, if it has one).
return false;
}
@Override
public void onConnectionFailed(@NonNull ConnectionResult connectionResult) {
}
}
なぜあなたはそれをやっていますか？それは実行可能ですが、あなた自身の作業のloootを行う準備ができています。 –
提案のおかげで@マーティンは、2つの場所の間の道順を得るために直接GoogleのAPIですか？ –
