Can I Change My Location Button in Android Maps

问题

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

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.

I know it is an late reply but this code works for me ..

     ImageView btnMyLocation = (ImageView) ((View) mapFragment.getView().findViewById(1).getParent()).findViewById(2);
        btnMyLocation.setImageResource(R.mipmap.ic_location_circle);

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

Happy coding..!

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...
