When developing a map focused customized Android Mobile App Development Company in Chennai, you will want your users to select an accurate location. Mostly you can use Google Maps API, which is robust and accurate.
Wondering How to set the Draggable Map view in Android? To do so, you got to select a location on the google map using draggable markers in the Google Search API.
Draggable Map in Android is a Google Map API. Determine your starting point on the map by clicking on the “current location” or change the location by dragging the pointer from the current location to your desired location anywhere on the map.
What is onMapReady Method?
onMapReady() method will automatically locate the user’s current location on the map.
Draggable Maps helps the users to select the map pointer to any accurate location they want to check. To do this “Google Search API” will be handy for the Android platform.
The onMapReady() method initializes the map and places the user on their current location of the Google map.
The most notable point here is the draggable(true) on the MarkerOptions() and the initialization of the startMarker to the map. Setting draggable to true makes the marker draggable and vice versa is true. Now with this, after the marker is shown, you can long-press the marker then drag it to your preferred location. Also, note that this is possible because if you can see on the map initialization we added a marker drag listener.
What is the role of Google Coordinates?
To understand the user’s exact current location, “Google Coordinates” will be the only choice. With the knowledge on the Google coordinates between the two points A & B, you can find,
- The distance between two points.
- The time it takes to travel from one point to another.
Google Place Search API:
Narrowing the Map further down, we call it “Google Place Search API”.
Google Place Search API may not be the right choice to go only with Google Coordinates. Instead, you can drag and drop the map pointer to your desired location to gather the information you are looking for.
