This is the first time using google map API and google places API. I am doing a demo application that displays the list hospitals (for example) nearest to the user's location with routes to each of the hospitals. I been able to get the user's location with the code below the:
public class MainActivity extends ActionBarActivity {
private GoogleMap map;
UiSettings mapSettings;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
map = ((MapFragment) getFragmentManager().findFragmentById(R.id.map)).getMap();
if (map != null) {
// map.addMarker(new MarkerOptions().position(myLocation).title("Start"));
map.setMyLocationEnabled(true);
mapSettings = map.getUiSettings();
mapSettings.setScrollGesturesEnabled(true);
mapSettings.setZoomControlsEnabled(true);
}
}
}
The xml file:
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:paddingLeft="@dimen/activity_horizontal_margin"
android:paddingRight="@dimen/activity_horizontal_margin"
android:paddingTop="@dimen/activity_vertical_margin"
android:paddingBottom="@dimen/activity_vertical_margin" tools:context=".MainActivity">
<fragment
android:id="@+id/map"
android:layout_width="match_parent"
android:layout_height="match_parent"
class="com.google.android.gms.maps.MapFragment" />
</RelativeLayout>
My question how do I get the list of hospitals using google places API and display them. Any help,tips,walkthrough or tutorials will really be appericaited.Thanks in Advance.
For Android, I tried to use Place picker for Android
. It can add the built-in place picker UI widget
to your app, so users can choose from a set of nearby places displayed on a map. It easy to use, you just need to do is:
int PLACE_PICKER_REQUEST = 1;
PlacePicker.IntentBuilder builder = new PlacePicker.IntentBuilder();
startActivityForResult(builder.build(this), PLACE_PICKER_REQUEST);
It will show the UI below to pick a place for you, and you can get the place info by using below:
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
if (requestCode == PLACE_PICKER_REQUEST) {
if (resultCode == RESULT_OK) {
Place place = PlacePicker.getPlace(data, this);
String toastMsg = String.format("Place: %s", place.getName());
Toast.makeText(this, toastMsg, Toast.LENGTH_LONG).show();
}
}
}
For more details, please refer to guide here and code here .
However, it cannot set the place type because it no feature for the Build in UI.. If you really need to set, you should use Google Places API Web Service API
here , search the location yourself, parse the JSON data, and show on your own UI.
A Nearby Search lets you search for places within a specified area. You can refine your search request by supplying keywords or specifying the type of place you are searching for.
A Nearby Search request is an HTTP URL of the following form:
https://maps.googleapis.com/maps/api/place/nearbysearch/output?parameters
Note that in parameters you need to set types=hospital
EDIT
Example on how to pass the search request for specific locations in JSON using the google places API web API web service API.

radius: 500

The below example returns a list of hospitals near London, England.
https://maps.googleapis.com/maps/api/place/nearbysearch/json?location=51.503186,-0.126446&radius=5000&types=hospital&key=API_KEY
Follow this link, it has all explained out,
in the String type='grocery_or_supermarket' replace it to be 'hospital' and you'll be good to go:
http://androidmastermind.blogspot.co.ke/2016/06/android-google-maps-with-nearyby-places.html
private void loadNearByPlaces(double latitude, double longitude)
//YOU Can change this type at your own will, e.g hospital, cafe, restaurant.... and see how it all works
{
mMap.clear();
Intent i = getIntent();
String type = hospital;
StringBuilder googlePlacesUrl =
new StringBuilder("https://maps.googleapis.com/maps/api/place/nearbysearch/json?");
googlePlacesUrl.append("location=").append(latitude).append(",").append(longitude);
googlePlacesUrl.append("&radius=").append(PROXIMITY_RADIUS);
googlePlacesUrl.append("&types=").append(type);
googlePlacesUrl.append("&sensor=true");
googlePlacesUrl.append("&key=" + GOOGLE_BROWSER_API_KEY);
JsonObjectRequest request = new JsonObjectRequest(googlePlacesUrl.toString(),
new Response.Listener<JSONObject>() {
@Override
public void onResponse(JSONObject result) {
Log.i(TAG, "onResponse: Result= " + result.toString());
parseLocationResult(result);
}
},
new Response.ErrorListener() {
@Override
public void onErrorResponse(VolleyError error) {
Log.e(TAG, "onErrorResponse: Error= " + error);
Log.e(TAG, "onErrorResponse: Error= " + error.getMessage());
}
});
AppController.getInstance().addToRequestQueue(request);
}
This will load the near by hospital according to your location.
Follow below code:
private static final String TAG_RESULT = "predictions";
JSONObject json;
ArrayList<String> names;
ArrayAdapter<String> adapter;
String browserKey = "Google API key";
//------------------------AutoComplete code--------------
public void updateList(String place) {
String input = "";
try {
input = "input=" + URLEncoder.encode(place, "utf-8");
} catch (UnsupportedEncodingException e1) {
e1.printStackTrace();
}
String output = "json";
String parameter = input + "&types=geocode&sensor=true&key=" + browserKey;
url = "https://maps.googleapis.com/maps/api/place/autocomplete/" + output + "?" + parameter;
JsonObjectRequest jsonObjReq = new JsonObjectRequest(Request.Method.GET, url,
null, new Response.Listener<JSONObject>() {
@Override public void onResponse(JSONObject response) {
System.out.println("response"+response);
try {
JSONArray ja = response.getJSONArray(TAG_RESULT);
for (int i = 0; i < ja.length(); i++) {
JSONObject c = ja.getJSONObject(i);
String description = c.getString("description");
System.out.println("description"+description);
names.add(description);
}
adapter = new ArrayAdapter<String>(
getApplicationContext(),
android.R.layout.simple_list_item_1, names) {
@Override public View getView(int position,
View convertView, ViewGroup parent) {
View view = super.getView(position,
convertView, parent);
TextView text = (TextView) view
.findViewById(android.R.id.text1);
text.setTextColor(Color.BLACK);
return view;
}
};
edittext_signup_city.setAdapter(adapter);
adapter.notifyDataSetChanged();
} catch (Exception e) {
}
}
}, new Response.ErrorListener() {
@Override public void onErrorResponse(VolleyError error) {
}
});
AppController.getInstance().addToRequestQueue(jsonObjReq, "jreq");
