getInfoWindow().įor example, the following InfoWindowAdapter implementation changes the info window contents. To customize just the contents of the info window but use the default frame, return a View from. getInfoWindow() and return null in getInfoContents(). To customize the entire info window, return a View in. Implement the AmazonMap.InfoWindowAdapter interface and pass it to tInfoWindowAdapter(). Remove method map windows#You can provide your own formatting for info windows by setting a custom info window adapter. The snippet is displayed on one line and is not wrapped, and so long text may be cut off in the window. The default info window displays the marker's title on the first line and the snippet on the second line. Note: The info window is only displayed if. It includes a simple title and snippet text that appears in the default info window. The following example adds a default marker to the location specified by the LatLng referenced by point. To override the marker click behavior, implement the AmazonMap.OnMarkerClickListener interface. You can disable or enable it with tMapToolbarEnabled(). Note that the toolbar option is enabled by default. Displays a toolbar with options to open the Amazon Maps app and get turn-by-turn driving directions.Displays a simple info window if the marker has a title defined.Then pass the MarkerOptions object to AmazonMap.addMarker().īy default, clicking a marker on the map does the following: Pass a LatLng to the MarkerOptions.position() method. When creating the MarkerOptions for the new marker, you must at a minimum set the location for the new marker. You place a marker at a specific geographic location by providing the latitude and longitude coordinates in a LatLng object. Adding Markers to the MapĪ marker indicates a single point on a map. Remove method map update#addCircle(), and so on) return a reference to the newly added item on the map, so you can update the properties of the object to change its appearance or behavior as necessary. You create an Options object for the item you want to draw, then pass that to the appropriate add method of the AmazonMap object.įor example, to place a marker on the map, you create a MarkerOptions object with the settings you want for the marker, then pass it to the AmazonMap.addMarker() method. The basic steps to draw an object on the map are the same for all the different supported objects. AmazonMap objects support markers, circles, lines (polylines), and polygons. Once you have a reference to an AmazonMap object, you can draw objects on the map, such as markers indicating points of interest or destinations, lines representing routes, and other shapes.

For your native maps app to work on Fire tablets running Fire OS 5+, you must recompile your app using the Maps API v2.5 and resubmit the app before October 26, 2020. You can also use other ways to iterate through a map.įor (Map.Entry mapElement : m1.Warning: Maps API v2.0 will be deprecated and replaced by Maps API v2.5 on October 26, 2020. In this example, you will traverse through a map in Java using the for-each loop and retrieve the values by the getValue() method. The only change is that you will have to pass the key of the value you wish to change, this time. You can also change the elements already added to a Java map using the same put() method to add elements. You will pass the key value in the remove() method, eliminating the associated value.Įxample: Changing Elements of a Map in Java This time you will use the HashMap class and the remove() method to remove elements from a map in Java. You will be using the HashMap class here to implement Java maps.Įxample: Removing Elements of a Map in Java In the example below, you will use the put() method to add elements to a map. Example: Adding Elements to a Map in Java You will use the most commonly used HashMap to perform these operations. Some of the primary operations you can perform on the maps in Java are: The Map interface in Java can be used with the classes that implement it, to perform various operations. The flowchart diagram depicted below represents the hierarchy of Map interface in Java.ĭifferent Operations That Are Performed With Maps in Java TreeMap class implements the SortedMap interface that extends the Map interface. The LinkedHashMap class extends HashMap that implements the Map interface.
