Using Google place API, you can find places near a location and get place details such as name, address, phone, etc. Google place API contains PlacePicker and Autocomplete UI widgets and GeoDataClient and PlaceDetectionClient APIs. In this post, you can learn how to use PlacePicker UI widget with place notes example Android app. PlacePicker UI widget displays places near a location on Google map and allows user to select a place.
To know how to get list of places near current location of device, please see nearby places PlaceDetectionClient API example.
To use Google places API, you need to create a project in Google developer console, enable API, create Key, add key to android manifest xml file and add libraries to build.gradle files, for detailed instructions on how to setup your for project to use Places API, please see nearby places Android example.
The example app first lets user pick a location by using place picker. Then it allows user to enter notes for the selected place and save it. View button in menu lets user to view list of save places and notes.
To use place picker, instantiate PlacePicker.IntentBuilder object optionally passing LatLngBounds to set location for the map to display. If LatLngBounds is not passed to the builder, place picker will show current device locations. Then start place picker activity by calling startActivityForResult passing the intent create using PlacePicker.IntentBuilder.
LatLngBounds latLngBounds = new LatLngBounds(new LatLng(47.64299816, -122.14351988),
new LatLng(47.64299816, -122.14351988));
PlacePicker.IntentBuilder builder = new PlacePicker.IntentBuilder();
builder.setLatLngBounds(latLngBounds);
try {
startActivityForResult(builder.build(this), PLACE_PICKER_REQ_CODE);
} catch (Exception e) {
Log.e(TAG, e.getStackTrace().toString());
} After the above step, place picker will show Google map as shown below.
You can drag up the nearby places list to view complete places list as shown below.
You can select a place either on the map or from the list. After selecting a place, place picker will show a confirmation screen as shown below
After you click select on the above screen, the selected place can be captured in onActivityResult method in the activity.
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
if (requestCode == LOC_REQ_CODE) {
if (resultCode == RESULT_OK) {
showPlacePicker();
}
}else if(requestCode == PLACE_PICKER_REQ_CODE){
if (resultCode == RESULT_OK) {
place = PlacePicker.getPlace(this, data);
name.setText(place.getName());
}
}
}After place picker flow is complete, screen will display activity layout. Our example layout displays the selected place name and allows user to enter notes. On submitting save, the place details and notes will be saved in Firestore database.
There is a menu action that will start an activity to view place notes in recycler view.
