Can I Change My Location Button in Android Maps

Question

We have a my location Icon in google maps like
I want to change this icon button with my desired Icon is there any way to replace this icon in the Google Maps. How can i do that in Android.

As the Question was unclear so i am adding Additional information. In https://support.google.com/maps/answer/3093609?hl=en you can see in section Get directions based on your location in point number 2 the icon had been shown

The Section just below in Fix your location-> Understand Location Symbols also explains these icons.

As you can see it is not the marker it's a location button as i had written So my question is how can i change that icon (location button) to my desired icon.

See this icon button is also shown in the google maps icon pic

Solution 1

Yes you can,

I solved this problem in my map fragment by re positioning my location button to the right bottom corner of view using code below, here is my MapsActivity.java :-

import android.support.v4.app.FragmentActivity;
import android.os.Bundle;
import android.view.View;
import android.view.ViewGroup;
import android.widget.RelativeLayout;

import com.google.android.gms.maps.CameraUpdateFactory;
import com.google.android.gms.maps.GoogleMap;
import com.google.android.gms.maps.OnMapReadyCallback;
import com.google.android.gms.maps.SupportMapFragment;
import com.google.android.gms.maps.model.LatLng;
import com.google.android.gms.maps.model.MarkerOptions;

public class MapsActivity extends FragmentActivity implements OnMapReadyCallback {

    private GoogleMap mMap;
    View mapView;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.fragment_map);
        // Obtain the SupportMapFragment and get notified when the map is ready to be used.
        SupportMapFragment mapFragment = (SupportMapFragment) getSupportFragmentManager()
                .findFragmentById(R.id.map);
        mapView = mapFragment.getView();
        mapFragment.getMapAsync(this);
            }

    /**
     * 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.
     */
    @Override
    public void onMapReady(GoogleMap googleMap) {
        mMap = googleMap;
        mMap.setMyLocationEnabled(true);

        // Add a marker in Sydney and move the camera
        LatLng sydney = new LatLng(-34, 151);
        mMap.addMarker(new MarkerOptions().position(sydney).title("Marker in Sydney"));
        mMap.moveCamera(CameraUpdateFactory.newLatLng(sydney));

        if (mapView != null &&
                mapView.findViewById(Integer.parseInt("1")) != null) {
            // Get the button view
            View locationButton = ((View) mapView.findViewById(Integer.parseInt("1")).getParent()).findViewById(Integer.parseInt("2"));
            // and next place it, on bottom right (as Google Maps app)
            RelativeLayout.LayoutParams layoutParams = (RelativeLayout.LayoutParams)
                    locationButton.getLayoutParams();
            // position on right bottom
            layoutParams.addRule(RelativeLayout.ALIGN_PARENT_TOP, 0);
            layoutParams.addRule(RelativeLayout.ALIGN_PARENT_BOTTOM, RelativeLayout.TRUE);
            layoutParams.setMargins(0, 0, 30, 30);
        }

    }
}

And here is layout of fragment :-

<FrameLayout 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"
    tools:context="com.infogird.www.location_button_reposition.MapFragment">

    <fragment xmlns:android="http://schemas.android.com/apk/res/android"
        xmlns:map="http://schemas.android.com/apk/res-auto"
        xmlns:tools="http://schemas.android.com/tools"
        android:id="@+id/map"
        android:name="com.google.android.gms.maps.SupportMapFragment"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        />
</FrameLayout>

I hope, this will solve your problem. Thanks.

Solution 2

Something I am using

    ImageView btnMyLocation = (ImageView) ((View) mapFragment.getView().findViewById(Integer.parseInt("1")).getParent()).findViewById(Integer.parseInt("2"));
    btnMyLocation.setImageResource(R.drawable.ic_current_location);

    RelativeLayout.LayoutParams layoutParams = (RelativeLayout.LayoutParams)
            btnMyLocation.getLayoutParams();

    layoutParams.addRule(RelativeLayout.ALIGN_PARENT_RIGHT, RelativeLayout.TRUE);
    layoutParams.addRule(RelativeLayout.ALIGN_PARENT_BOTTOM, RelativeLayout.TRUE);
    layoutParams.setMargins(0, 0, 30, 30);
    btnMyLocation.setLayoutParams(layoutParams);

Hope it will help...

Does it works with signed apk? Its working for me in debug mode but not in release mode.

what is the exact problem you are facing in release mode ? I think, in the map API V2, the ONLY thing that change between a release version and a debug version is the Key that you register here code.google.com/apis/console If debug is working and final release is not, it's the only change necessary. So I suggest you to double check the hash code of your release keystore and make sure that it's properly input on the Google API Console. @seema

its done. Issue was, we had used integer value 1. Replaced it with Integer.parseInt("1") and it worked.

[Priya Jagtap]

I am glad, you did it. But the code given above itself uses Integer.parseInt("1"); @seema

Why are you hardcoding then parsing integer values? Beyond that you should try to explain what the code is doing to help the OP understand it.
