So ändern Sie die position von "Mein Standort" - Button in Google Maps mit android studio

Löste ich dieses problem in meiner map fragment durch re-Positionierung "mein Standort" - Taste auf der rechten unteren Ecke der Ansicht mithilfe der folgenden code, hier ist meine
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);
        }

    }
}

Und hier ist das layout des fragments :-

<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>

Ich hoffe, dies wird Ihr problem lösen. Danke.

Können Sie folgenden code verwenden, für alle Bedingungen, wie zum Beispiel:
1.Wenn Sie möchten, zeigen Lage-Schaltfläche in der oberen rechten
2.Wenn Sie möchten, zeigen Lage-Schaltfläche in der unteren rechten
3.Wenn Sie möchten, zeigen Lage-Schaltfläche in der unteren linken

1.Wenn Sie wollen, um zu zeigen, Lage-Schaltfläche in der oberen rechten

View locationButton = ((View) mapView.findViewById(Integer.parseInt("1")).getParent()).findViewById(Integer.parseInt("2"));
            RelativeLayout.LayoutParams rlp = (RelativeLayout.LayoutParams) locationButton.getLayoutParams();
            //position on right bottom
            rlp.addRule(RelativeLayout.ALIGN_PARENT_TOP, 0);
            rlp.addRule(RelativeLayout.ALIGN_PARENT_TOP, RelativeLayout.TRUE);

2.Wenn Sie möchten, zeigen Lage-Schaltfläche in der unteren rechten

 View locationButton = ((View) mapView.findViewById(Integer.parseInt("1")).getParent()).findViewById(Integer.parseInt("2"));
            RelativeLayout.LayoutParams rlp = (RelativeLayout.LayoutParams) locationButton.getLayoutParams();
            //position on right bottom
            rlp.addRule(RelativeLayout.ALIGN_PARENT_TOP, 0);
            rlp.addRule(RelativeLayout.ALIGN_PARENT_BOTTOM, RelativeLayout.TRUE);rlp.setMargins(0,0,30,30);

3.Wenn Sie möchten, zeigen Lage-Schaltfläche in der unteren linken

 View locationButton = ((View) mapView.findViewById(Integer.parseInt("1")).getParent()).findViewById(Integer.parseInt("2"));
            RelativeLayout.LayoutParams rlp = (RelativeLayout.LayoutParams) locationButton.getLayoutParams();
            //position on right bottom


            rlp.addRule(RelativeLayout.ALIGN_PARENT_BOTTOM, RelativeLayout.TRUE);
            rlp.addRule(RelativeLayout.ALIGN_PARENT_LEFT, RelativeLayout.TRUE);
            rlp.addRule(RelativeLayout.ALIGN_PARENT_RIGHT, 0);
            rlp.addRule(RelativeLayout.ALIGN_PARENT_TOP, 0);

             rlp.addRule(RelativeLayout.ALIGN_PARENT_END, 0);
            rlp.addRule(RelativeLayout.ALIGN_END, 0);
            rlp.addRule(RelativeLayout.ALIGN_PARENT_LEFT);
            rlp.setMargins(30, 0, 0, 40);

Viel Glück

Ihre Arbeit display Mein Standort " - Button Unten Rechts auf MapView

XML

<com.google.android.gms.maps.MapView
    android:id="@+id/mapView"
    android:layout_width="match_parent"
    android:layout_height="match_parent" />

JAVA

private MapView mMapView;

mMapView = (MapView) findViewById(R.id.mapView);

mMapView.getMapAsync(new OnMapReadyCallback() {
    @Override
    public void onMapReady(final GoogleMap mMap) {
        if (ContextCompat.checkSelfPermission(getActivity(), Manifest.permission.ACCESS_FINE_LOCATION) == PackageManager.PERMISSION_GRANTED) {
            mMap.setMyLocationEnabled(true);
        }

        if (mMapView != null && mMapView.findViewById(Integer.parseInt("1")) != null) {
            View locationButton = ((View) mMapView.findViewById(Integer.parseInt("1")).getParent()).findViewById(Integer.parseInt("2"));
            RelativeLayout.LayoutParams layoutParams = (RelativeLayout.LayoutParams) locationButton.getLayoutParams();
            layoutParams.addRule(RelativeLayout.ALIGN_PARENT_TOP, 0);
            layoutParams.addRule(RelativeLayout.ALIGN_PARENT_BOTTOM, RelativeLayout.TRUE);
            layoutParams.setMargins(0, 0, 20, 20);
        }
    }
});

Fügen Sie diesen code in onCreate Methode, nach der mapFragment.getMapAsync(this). Es wird legen Sie Ihre Meine Lage - Taste rechts unten im Display.

View locationButton = ((View) mapFragment.getView().findViewById(Integer.parseInt("1")).getParent()).findViewById(Integer.parseInt("2"));
RelativeLayout.LayoutParams rlp = (RelativeLayout.LayoutParams) locationButton.getLayoutParams();
rlp.addRule(RelativeLayout.ALIGN_PARENT_TOP, 0);
rlp.addRule(RelativeLayout.ALIGN_PARENT_BOTTOM, RelativeLayout.TRUE);
rlp.setMargins(0, 0, 30, 30);

Leider kann man nur padding, etwa so:

@Override
public void onMapReady(GoogleMap googleMap) {
   googleMap.setPadding(left, top, right, bottom);
   ...
}

Ich landete meine eigene und die Einbettung in ein frame-layout mit layout_gravity angeben, wo ich es will, in diesem Fall von unten/Ende:

<FrameLayout
   android:layout_width="match_parent"
   android:layout_height="300dp">

   <fragment
       android:id="@+id/map"
       android:name="com.google.android.gms.maps.SupportMapFragment"
       android:layout_width="match_parent"
       android:layout_height="match_parent"
       .../>


     <ImageView
       android:id="@+id/myLocationCustomButton"
       android:layout_width="@dimen/custom_my_location_button_size"
       android:layout_height="@dimen/custom_my_location_button_size"
       android:layout_gravity="bottom|end"
       android:background="@drawable/disc"
       android:backgroundTint="@android:color/white"
       android:padding="@dimen/margin_smallest"
       android:src="@drawable/ic_my_location"
       ../>
</FrameLayout>

Dann, in der Aktivität, die ich initialisiert und gestartet, google-api-Clients, die ich verwenden können, um fetch aktuellen Lage, wenn nötig, indem Sie die Taste während ein klicken, sehen Sie die Schaltfläche, klicken Sie auf listener unten:

@Override
protected void onCreate(@Nullable Bundle savedInstanceState) {
    ...
    if (googleApiClient == null) {
        googleApiClient = new GoogleApiClient.Builder(this)
                .addConnectionCallbacks(this)
                .addOnConnectionFailedListener(this)
                .addApi(LocationServices.API)
                .build();
    }

    myLocationButton = rootView.findViewById(R.id.myLocationCustomButton);
}

@Override
protected void onStart() {
    googleApiClient.connect();
    super.onStart();
}

@Override
protected void onStop() {
    googleApiClient.disconnect();
    super.onStop();
}

@Override
public void onConnected(@Nullable Bundle bundle) {
    myLocationButton.performClick();
}

@Override
public void onConnectionSuspended(int i) {
}

@Override
public void onConnectionFailed(@NonNull ConnectionResult connectionResult) {
}

@Override
public void onMapReady(final GoogleMap googleMap) {
    this.googleMap = googleMap;

    myLocationButton.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            Location location = LocationServices.FusedLocationApi.getLastLocation(googleApiClient);
            CameraUpdate cameraUpdate = CameraUpdateFactory.newLatLngZoom(new LatLng(location.getLatitude(), location.getLongitude()), 16);
            MainActivity.this.googleMap.animateCamera(cameraUpdate, 250, null);
        }
    });

Meine app-sub-Moduls build.gradle auch:

ext {
    playServicesVersion = "8.4.0"
}

dependencies {
   ...     
   compile "com.google.android.gms:play-services-location:${playServicesVersion}"
   ...
}

Hoffe, das hilft.
