open google maps through intent for specific locat

问题:

I'm designing one application in which I want to show specific location on Map. I'm passing String of address which is already placed on Google Map. Following is my Intent code..

String url = "http://maps.google.com/maps?daddr="+address;
Intent intent = new Intent(android.content.Intent.ACTION_VIEW,  Uri.parse(url));
startActivity(intent);

But it gives me Google Map for getting direction. I know why that so, because I used daddr in url but I don't know what to use for specific location..Please tell me what to use there..

回答1:

I have not tested this but you could try :

First method:

String uri = String.format(Locale.ENGLISH, "geo:%f,%f", latitude, longitude);
Intent intent = new Intent(Intent.ACTION_VIEW, Uri.parse(uri));
context.startActivity(intent);

EDIT: This might not work with Google maps 7,0

hence you could change the uri to :

Second option:

String geoUri = "http://maps.google.com/maps?q=loc:" + lat + "," + lng + " (" + mTitle + ")";

where mTitle is the name of the location.

Third option:

geo:0,0?q=my+street+address

Fourth option:

String map = "http://maps.google.co.in/maps?q=" + yourAddress;

Hope that works and helps :D..

Get Lat-Lng Using this web-service

http://maps.google.com/maps/api/geocode/json?address=" + address + "&sensor=false

Then Pass it to this code

    String strUri = "http://maps.google.com/maps?q=loc:" + lat + "," + lng + " (" + "Label which you want" + ")";
    Intent intent = new Intent(android.content.Intent.ACTION_VIEW, Uri.parse(strUri));

    intent.setClassName("com.google.android.apps.maps", "com.google.android.maps.MapsActivity");

    startActivity(intent);

I hope it will help you

Thank you.

The latest version of map provides better solution. If you wish show an address on map use below code.

Uri mapUri = Uri.parse("geo:0,0?q=" + Uri.encode(address));
Intent mapIntent = new Intent(Intent.ACTION_VIEW, mapUri);
mapIntent.setPackage("com.google.android.apps.maps");
startActivity(mapIntent);

If you want to display using latitude and longitude values, use below method.

Uri mapUri = Uri.parse("geo:0,0?q=lat,lng(label)");
Intent mapIntent = new Intent(Intent.ACTION_VIEW, mapUri);
mapIntent.setPackage("com.google.android.apps.maps");
startActivity(mapIntent);

Lat and lng being the latitude and longitude you wish to display, the label here is optional.

You should use something like this

Intent intent = new Intent(android.content.Intent.ACTION_VIEW, 
    Uri.parse("http://maps.google.com/maps?saddr=20.344,34.34&daddr=20.5666,45.345"));
startActivity(intent);

And to drop a pin

try {
    Intent intent = new Intent(android.content.Intent.ACTION_VIEW,
        Uri.parse("geo:" + AppointmentDetailLayout.docLatitude
            + "," + AppointmentDetailLayout.docLongitude
            + "?q=" + AppointmentDetailLayout.docLatitude
            + "," + AppointmentDetailLayout.docLongitude
            + "(" + label + ")"));
    intent.setComponent(new ComponentName(
        "com.google.android.apps.maps",
        "com.google.android.maps.MapsActivity"));
    context.startActivity(intent);
    } catch (ActivityNotFoundException e) {

    try {
        context.startActivity(new Intent(
            Intent.ACTION_VIEW,
            Uri.parse("market://details?id=com.google.android.apps.maps")));
    } catch (android.content.ActivityNotFoundException anfe) {
        context.startActivity(new Intent(
            Intent.ACTION_VIEW,
            Uri.parse("http://play.google.com/store/apps/details?id=com.google.android.apps.maps")));
    }

    e.printStackTrace();
    }

This will work like a charm. Make sure to check for existence for Google Maps, so this can work universally across all non Google devices also. It will open in browser in such cases.

Also remember dont have www in the URL. Else this will not work.

        Intent i = new Intent(Intent.ACTION_VIEW, Uri.parse("http://maps.google.com/maps?q=loc:" + latitude + "," + longitude);
        i.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK); // Only if initiating from a Broadcast Receiver
        String mapsPackageName = "com.google.android.apps.maps";
        if (Utility.isPackageExisted(context, mapsPackageName)) {
            i.setClassName(mapsPackageName, "com.google.android.maps.MapsActivity");
            i.setPackage(mapsPackageName);
        }
        context.startActivity(i);

Uri gmmIntentUri = Uri.parse("geo:37.7749,-122.4194");
Intent mapIntent = new Intent(Intent.ACTION_VIEW, gmmIntentUri);
mapIntent.setPackage("com.google.android.apps.maps");
if (mapIntent.resolveActivity(getPackageManager()) != null) {
    startActivity(mapIntent);
}

                    startActivity(intent);
                }catch (ActivityNotFoundException  ane){

                    Toast.makeText(activity, "Please Install Google Maps ", Toast.LENGTH_LONG).show();
                }catch (Exception ex){
                    ex.getMessage();
                }
            }
        });

This helper method using uriBuilder for cleaner code and handle condition if there is no activity on device that can open map

public static boolean openMap(Context context, String address) {
    Uri.Builder uriBuilder = new Uri.Builder()
            .scheme("geo")
            .path("0,0")
            .appendQueryParameter("q", address);
    Intent intent = new Intent(Intent.ACTION_VIEW, uriBuilder.build());
    if (intent.resolveActivity(context.getPackageManager()) != null) {
        context.startActivity(intent);
        return true;
    }
    return false;
}
