as I know Google does not allow developers to customize place picker layout ,
so I want to make a place picker like the photo below.
it is from deliveroo app, I used map api but it is not totally like this photo.
this picker act like place picker api it is customized.
this is my code:
public class Map extends AppCompatActivity implements OnMapReadyCallback {
private GoogleMap mMap;
private LatLng markerLatLong;
private static final int REQUEST_CODE_LOCATION_ENABLE = 1;
private static final int PLACE_AUTOCOMPLETE_REQUEST_CODE = 2;
private static String TAG = Map.class.getSimpleName();
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.map);
setToolbar();
setFragment();
}
public void setFragment() {
SupportMapFragment mapFragment = (SupportMapFragment) getSupportFragmentManager()
.findFragmentById(R.id.map);
mapFragment.getMapAsync(this);
}
public void setToolbar() {
Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
setSupportActionBar(toolbar);
if (getSupportActionBar() != null) {
getSupportActionBar().setDisplayShowTitleEnabled(false);
getSupportActionBar().setDisplayHomeAsUpEnabled(true);
}
onSearchPlacesClicked(toolbar);
}
@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
if (requestCode == REQUEST_CODE_LOCATION_ENABLE) {
if (resultCode == RESULT_OK) {
Log.e(TAG, "location enabled");
setLocation();
}
}else if (requestCode == PLACE_AUTOCOMPLETE_REQUEST_CODE) {
if (resultCode == RESULT_OK) {
Place place = PlaceAutocomplete.getPlace(this, data);
Log.e(TAG, "Place: " + place.getName());
setPlace(place.getLatLng());
} else if (resultCode == PlaceAutocomplete.RESULT_ERROR) {
Status status = PlaceAutocomplete.getStatus(this, data);
// TODO: Handle the error.
Log.i(TAG, status.getStatusMessage());
} else if (resultCode == RESULT_CANCELED) {
// The user canceled the operation.
}
}
}
/**
* Manipulates the map once available.
* This callback is triggered when the map is ready to be used.
* This is where we can add markers or lines, add listeners or move the camera. In this case,
* we just add a marker near Sydney, Australia.
* If Google Play services is not installed on the device, the user will be prompted to install
* it inside the SupportMapFragment. This method will only be triggered once the user has
* installed Google Play services and returned to the app.

Make activity for map and call that where you want location:
<LinearLayout
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:orientation="vertical"
tools:context=".Activity.InsertMapsActivity">
<Button
android:layout_width="wrap_content"
android:id="@+id/btn_set_garage_location"
android:text="set location"
android:layout_height="wrap_content"/>
<fragment
android:id="@+id/map"
android:name="com.google.android.gms.maps.SupportMapFragment"
android:layout_width="match_parent"
android:layout_height="match_parent"/>
java code:
public class InsertMapsActivity extends FragmentActivity implements LocationListener
{
private GoogleMap googleMap;
private LatLng garageLocation;
Button btnSetGarageLocation;
@Override
protected void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_insert_maps);
btnSetGarageLocation = (Button) findViewById(R.id.btn_set_garage_location);
int status = GooglePlayServicesUtil.isGooglePlayServicesAvailable(getBaseContext());
// Obtain the SupportMapFragment and get notified when the map is ready to be used.
if (status != ConnectionResult.SUCCESS)
{ // Google Play Services are not available
int requestCode = 10;
Dialog dialog = GooglePlayServicesUtil.getErrorDialog(status, this, requestCode);
dialog.show();
}
else
{ // Google Play Services are available
// Getting reference to the SupportMapFragment of activity_main.xml
SupportMapFragment fm = (SupportMapFragment) getSupportFragmentManager().findFragmentById(R.id.map);
// Getting GoogleMap object from the fragment
googleMap = fm.getMap();
// Enabling MyLocation Layer of Google Map
googleMap.setMyLocationEnabled(true);
// Getting LocationManager object from System Service LOCATION_SERVICE
LocationManager locationManager = (LocationManager) getSystemService(LOCATION_SERVICE);
// Creating a criteria object to retrieve provider
Criteria criteria = new Criteria();
// Getting the name of the best provider
String provider = locationManager.getBestProvider(criteria, true);
// Getting Current Location
if (ActivityCompat.checkSelfPermission(this, Manifest.permission.ACCESS_FINE_LOCATION) != PackageManager.PERMISSION_GRANTED && ActivityCompat.checkSelfPermission(this, Manifest.permission.ACCESS_COARSE_LOCATION) != PackageManager.PERMISSION_GRANTED)
{
// TODO: Consider calling
return;
}
Location location = locationManager.getLastKnownLocation(provider);
if(location!=null){
onLocationChanged(location);
}
locationManager.requestLocationUpdates(provider, 100, 0, this);
btnSetGarageLocation.setOnClickListener(new View.OnClickListener()
{
@Override
public void onClick(View v)
{
Intent intent = getIntent();
intent.putExtra("location_lat",garageLocation.latitude);
intent.putExtra("location_lng",garageLocation.longitude);
setResult(RESULT_OK,intent);
finish();
}
});
}
googleMap.setOnMapClickListener(new GoogleMap.OnMapClickListener()
{
@Override
public void onMapClick(LatLng latLng)
{
googleMap.clear();
googleMap.addMarker(new MarkerOptions().position(latLng).title("Custom location").icon(BitmapDescriptorFactory.defaultMarker(BitmapDescriptorFactory.HUE_BLUE)));
garageLocation = latLng;
}
});
}
@Override
public void onLocationChanged(Location location)
{
// Getting latitude of the current location
double latitude = location.getLatitude();
// Getting longitude of the current location
double longitude = location.getLongitude();
// Creating a LatLng object for the current location
LatLng latLng = new LatLng(latitude, longitude);
// Showing the current location in Google Map
googleMap.moveCamera(CameraUpdateFactory.newLatLng(latLng));
// Zoom in the Google Map
googleMap.animateCamera(CameraUpdateFactory.zoomTo(15));
googleMap.getMaxZoomLevel();
// Setting latitude and longitude in the TextView tv_location
}
@Override
public void onStatusChanged(String provider, int status, Bundle extras)
{
}
@Override
public void onProviderEnabled(String provider)
{
}
@Override
public void onProviderDisabled(String provider)
{
}
}
in activity:
private int MAP = 2;
Intent intent = new Intent(getApplicationContext(),InsertMapsActivity.class);
startActivityForResult(intent, MAP);
end of your activity:
@Override
public void onActivityResult(int requestCode, int resultCode, Intent data)
{
super.onActivityResult(requestCode, resultCode, data);
ImageView garageImage = new ImageView(this);
if (resultCode == Activity.RESULT_OK)
{
}
if(requestCode == MAP)
{
double lat = (double) data.getExtras().get("location_lat");
double lng = (double) data.getExtras().get("location_lng");
}
}
This code works like a charm. However it seems that there are new updates to this as Google made new releases. Key differences are the following:
OnMapReadyCallback must be implemented:
public class InsertMapsActivity extends FragmentActivity implements LocationListener, OnMapReadyCallback
@Override public void onMapReady(GoogleMap googleMap) { this.googleMap = googleMap;
}
This code will no longer work:
// Getting reference to the SupportMapFragment of activity_main.xml SupportMapFragment fm = (SupportMapFragment) getSupportFragmentManager().findFragmentById(R.id.map); // Getting GoogleMap object from the fragment googleMap = fm.getMap();
Instead use this, which calls the callback in #1.
// Obtain the SupportMapFragment and get notified when the map is ready to be used.
SupportMapFragment mapFragment = (SupportMapFragment) getSupportFragmentManager()
.findFragmentById(R.id.map);
mapFragment.getMapAsync(this);
References to the googleMap object need be placed in the OnMapReady callback to ensure that the object is initially assigned else null pointer errors would occur:
@Override public void onMapReady(GoogleMap googleMap) { this.googleMap = googleMap; // Enabling MyLocation Layer of Google Map this.googleMap.setMyLocationEnabled(true); googleMap.setOnMapClickListener(new GoogleMap.OnMapClickListener() { @Override public void onMapClick(LatLng latLng) { googleMap.clear(); googleMap.addMarker(new MarkerOptions().position(latLng).title("Custom location").icon(BitmapDescriptorFactory.defaultMarker(BitmapDescriptorFactory.HUE_BLUE))); garageLocation = latLng; } }); }
