I'm using Polaris map library in my android app.
https://github.com/cyrilmottier/Polaris
I've Google Map with some geo points. I'm reading them from database. I've added two buttons on the map activity - "next" and "previous" to navigate between points.
mc.animateTo(geopoints.get(arrayID));
"arrayID" is the id of the next geo point and "mc" is map controller.
It works great but I want to add one more feature.
I want annotation to be visible by default while moving between points. After click on the "next" button I want to be moved to the next point on my map and it's annotation should be visible (not only after clicking on it).
Probably there is an easy way to do it.
I should probably do something with calloutView but I can't figure it out how to do that.
I made something like this. But it's not working properly.
MapCalloutView calloutView;
calloutView = new MapCalloutView(getApplicationContext());
calloutView.setDisclosureEnabled(true);
calloutView.setClickable(true); calloutView.setLeftAccessoryView(getLayoutInflater().inflate(R.layout.accessory, calloutView, false));
calloutView.show(mMapView, geopoints.get(arrayID), false);
calloutView.setData(annotations.get(arrayID));
It is showing me bubble but it creates new calloutView which is wrong I think. For example Polaris listeners are not working. I can't deselect callout etc...
My mistake! It was so easy...
I don't need to play with MapcalloutView in Polaris.
mMapView.setSelectedAnnotation(arrayID);

I'm trying to make an android application that has an interactive map.
Then when the app is run and the user selects the map option it will enable location services to show the user where they are on the custom map- and notify them if they are outside of the bounds predetermined.
If they are within the predetermined bounds, I want to show their location on the map while the map is being viewed.
I'd also eventually like to add "areas" to the map that allows a button press or interaction. Example: a "button press" that would allow text to display.
I'm just looking to see if there a either a solution built into to the google map API already, or if there is another open-source solution that has already been made.
For your so called "areas" you can use markers that are clickable and can add listener to them to perform custom click (open new Fragment/Activity or show some info image text etc.). This is good place to start :
https://developers.google.com/maps/documentation/android-api/marker
For predetermined bounds you will need a projection that translate between screen location(coordinates) to geographic coordinates and vice versa.
Nice info for projection can be found here :
https://developers.google.com/android/reference/com/google/android/gms/maps/Projection
You checkout this example on github created by me Link to github
I'm trying to make a button that will open a map (GPS) that will show you a specific place.
I have no idea how to open a map through libGDX, if someone knows anything like that please answer me.
At first you should think a bit more about your project.
I suggest also that you split your main goal in smaller parts.
Instead of creating a button which opens a map.
Create a Button
Create a ClickListener
What kind of a map do you want do show?
Decide if it's a map file or your current position on a map.
And then you'll know what you need. And then you can google.
Good Luck!
i want to do the following. I am having a google map that displays my position. I have created separately a compass. Now what I want is to combine them and put the compass on top of my map. I do not know where to start for it, and how I skould implement it since data of te compass are also being updated every second I move?
If you have any tutorials please give me link cause I have not been able to find any.
In my previous app I have used a class extending Overlay but this was for only putting a pin or something like this.
You may add the image as a custom control: example (it's the home-button in the example)
Recently I show the ubicabs taxi booking app. I found very nice functionality inside it. In this app they have google maps for showing markers, but they have used very good UI component for that. Also I found one more uniqueness is that whenever user moves or change the position of marker through touch it will fetch the current location. One thing that I know is that it is using the onTouchEvent of Overlay but how to create that marker balloon and how to get updated location on the basis of that marker.
I am attaching a preview of that marker here. Also would like to know that how can we scroll the text inside that balloon?
The best overlay open project I have found so far is this one, link. But it is nothing compared to the picture above. Would also like to know how they created this! Great Question and picture ;)
I’m new to development, specifically Android. Through tutorials, I’ve managed to display a map with a marker for a building that displays a “toast” box with text identifying that building, when tapped (I fashioned it after the “Noo Yawk” example). I need to display a new full screen with a photo of that building and text describing it, and use the back button to return to the map. I need to do this for at least 30 buildings.
Do I need to start a new activity for each building? It would seem complicated and resource intensive. If so, where will the photo and text reside? Do I need to have a button in the layout to call the map again? Or is there a simpler way to do this? Given the number of buildings, will content management or a database be required?
Thanks in advance and forgive my ignorance. I’ve parsed so many articles and tutorials that I’m becoming confused.
I would just show Dialog with ImageView (photo), TextView (information) and Button (to close Dialog).
Android dialog Screen Example
I think it would be better to keep photo and info inside database and pass them into Dialog before show.
You can display any view on top of the view. Add marker to your map and listen for onClick events on your marker. (see https://developers.google.com/maps/documentation/android/reference/com/google/android/gms/maps/GoogleMap.OnMarkerClickListener)
Within the onClick event you show a view on top of the map.
Do not try to use the InfoWindows of the Maps API as the InfoWindows are rendered as an image and not as a live view. Therefor async loading of your images is not possible with InfoWindows.
