更改谷歌地图 API 的“我的位置”按钮的位置

我正在使用谷歌地图 Android API v2，我需要一个方法来机会的位置“我的位置”按钮。

我得到的“我的位置”按钮是这样的:

GooglePlayServicesUtil.isGooglePlayServicesAvailable(getApplicationContext());
final GoogleMap map = ((SupportMapFragment) getSupportFragmentManager()
.findFragmentById(R.id.map)).getMap();


// This gets the button
map.setMyLocationEnabled(true);

This may not be the best solution, but you could place your own button over the map and handle it yourself. It would take the following:-

1) Put the map in a frameLayout and add your button on top. E.g.

<FrameLayout
android:id="@+id/mapFrame"
android:layout_width="match_parent"
android:layout_height="match_parent" >






<fragment
xmlns:map="http://schemas.android.com/apk/res-auto"
android:id="@+id/mapFragment"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
class="com.google.android.gms.maps.MapFragment"
map:mapType="normal"
map:uiCompass="true" />


<ImageButton
android:id="@+id/myMapLocationButton"
android:layout_width="36dp"
android:layout_height="36dp"
android:layout_gravity="bottom|right"
android:background="@drawable/myMapLocationDrawable"
android:contentDescription="My Location" />


</FrameLayout>

2) Edit the maps UI settings so the button doesn't appear when you call setMyLocationEnabled(true). You can do this via map.getUiSettings(). setMyLocationButtonEnabled(false);

3) Handle the click of your new button to emulate what the supplied button does. E.g. call mMap.setMyLocationEnabled(...); and pan the map to the current location.

Hope that helps, or hope someone comes a long with a simpler solution for you ;-)

I had the same problem. I ended up using the Hierarchy Viewer to identify the view used to display the button and manipulated it. Very hacky, I know, but could not figure out a different way.

See the method below. It lives inside a class that extends SupportMapFragment. It gets the container view for the button and displays it at the bottom, centered horizontally. 

/**
* Move my position button at the bottom of map
*/
private void resetMyPositionButton()
{
//deep paths for map controls
ViewGroup v1 = (ViewGroup)this.getView();
ViewGroup v2 = (ViewGroup)v1.getChildAt(0);
ViewGroup v3 = (ViewGroup)v2.getChildAt(0);
ViewGroup v4 = (ViewGroup)v3.getChildAt(1);


//my position button
View position =  (View)v4.getChildAt(0);


int positionWidth = position.getLayoutParams().width;
int positionHeight = position.getLayoutParams().height;


//lay out position button
RelativeLayout.LayoutParams positionParams = new RelativeLayout.LayoutParams(positionWidth,positionHeight);
int margin = positionWidth/5;
positionParams.setMargins(0, 0, 0, margin);
positionParams.addRule(RelativeLayout.CENTER_HORIZONTAL, RelativeLayout.TRUE);
positionParams.addRule(RelativeLayout.ALIGN_PARENT_BOTTOM, RelativeLayout.TRUE);
position.setLayoutParams(positionParams);
}

It was a bit of a struggle to get this working. But I got it done, and in the process also started to move the zoom buttons around. Here my complete code:

package com.squirrel.hkairpollution;


import android.os.Bundle;
import android.util.Log;
import android.view.LayoutInflater;
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.SupportMapFragment;
import com.google.android.gms.maps.UiSettings;
import com.google.android.gms.maps.model.LatLng;


public class MySupportMapFragment extends SupportMapFragment {


private static final String TAG = HKAirPollution.TAG;


public MySupportMapFragment() {
return;
}


@Override
public View onCreateView(LayoutInflater arg0, ViewGroup arg1, Bundle arg2) {
Log.v(TAG, "In overridden onCreateView.");
View v = super.onCreateView(arg0, arg1, arg2);
Log.v(TAG, "Initialising map.");
initMap();
return v;
}


@Override
public void onViewCreated (View view, Bundle savedInstanceState) {
super.onViewCreated(view, savedInstanceState);
resetButtons();
}


private void initMap(){
UiSettings settings = getMap().getUiSettings();
settings.setAllGesturesEnabled(true);
settings.setMyLocationButtonEnabled(true);
LatLng latLong = new LatLng(22.320542, 114.185715);
getMap().moveCamera(CameraUpdateFactory.newLatLngZoom(latLong,11));
}




/**
* Move my position button at the bottom of map
*/
private void resetButtons()
{
// Get a reference to the zoom buttons and the position button.
ViewGroup v1 = (ViewGroup)this.getView();
ViewGroup v2 = (ViewGroup)v1.getChildAt(0);
ViewGroup v3 = (ViewGroup)v2.getChildAt(0);
ViewGroup v4 = (ViewGroup)v3.getChildAt(1);


// The My Position button
View position =  (View)v4.getChildAt(0);
int positionWidth = position.getLayoutParams().width;
int positionHeight = position.getLayoutParams().height;


// Lay out the My Position button.
RelativeLayout.LayoutParams positionParams = new RelativeLayout.LayoutParams(positionWidth,positionHeight);
int margin = positionWidth/5;
positionParams.setMargins(0, 0, 0, margin);
positionParams.addRule(RelativeLayout.CENTER_HORIZONTAL, RelativeLayout.TRUE);
positionParams.addRule(RelativeLayout.ALIGN_PARENT_TOP, RelativeLayout.TRUE);
position.setLayoutParams(positionParams);


// The Zoom buttons
View zoom = (View)v4.getChildAt(2);
int zoomWidth = zoom.getLayoutParams().width;
int zoomHeight = zoom.getLayoutParams().height;


// Lay out the Zoom buttons.
RelativeLayout.LayoutParams zoomParams = new RelativeLayout.LayoutParams(zoomWidth, zoomHeight);
zoomParams.setMargins(0, 0, 0, margin);
zoomParams.addRule(RelativeLayout.ALIGN_PARENT_RIGHT, RelativeLayout.TRUE);
zoomParams.addRule(RelativeLayout.ALIGN_PARENT_TOP, RelativeLayout.TRUE);
zoom.setLayoutParams(zoomParams);
}
}

One way to deal with this problem. Delete default button and create your own. In OnCreate statement add the next:

GoogleMap mMap = ((MapView) inflatedView.findViewById(R.id.mapview)).getMap();
LocationManager locationManager =
(LocationManager)getActivity().getSystemService(Context.LOCATION_SERVICE);
Criteria criteria = new Criteria();
String provider = locationManager.getBestProvider(criteria, false);
Location location = locationManager.getLastKnownLocation(provider);
locationManager.requestLocationUpdates(provider, 2000, 1,  this);


mMap.setMyLocationEnabled(true);
mMap.getUiSettings().setMyLocationButtonEnabled(false); // delete default button


Imagebutton imgbtn = (ImageButton) view.findViewById(R.id.imgbutton); //your button
imgbtn.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View view) {
mMap.animateCamera(CameraUpdateFactory.newLatLngZoom(new
LatLng(location.getLatitude(),
location.getLongitude()), 15));
}
});

You can use following approach:

    View myLocationParent = ((View) getView().findViewById(1).getParent());
View myLocationParentParent = ((View) myLocationParent.getParent());


// my position button


int positionWidth = myLocationParent.getLayoutParams().width;
int positionHeight = myLocationParent.getLayoutParams().height;


// lay out position button
FrameLayout.LayoutParams positionParams = new FrameLayout.LayoutParams(
positionWidth, positionHeight);
positionParams.setMargins(0, 100, 0, 0);


myLocationParent.setLayoutParams(positionParams);

You can get the "My Location" button and move it, like :

public class MapFragment extends SupportMapFragment {
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
View mapView = super.onCreateView(inflater, container, savedInstanceState);


// Get the button view
View locationButton = ((View) mapView.findViewById(1).getParent()).findViewById(2);


// and next place it, for exemple, on bottom right (as Google Maps app)
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);
}
}

最佳答案

Just use GoogleMap.setPadding(left, top, right, bottom), which allows you to indicate parts of the map that may be obscured by other views. Setting padding re-positions the standard map controls, and camera updates will use the padded region.

First, obtain Google Map View:

 View mapView = ((MapFragment) getFragmentManager().findFragmentById(R.id.map)).getView();

Then find MyLocation button (id's from Android Studio debugger):

 View btnMyLocation = ((View) mapView.findViewById(1).getParent()).findViewById(2);

Finally, just set new RelativeLayout params for MyLocation button (align parent right + center vertically in this case):

RelativeLayout.LayoutParams params = new RelativeLayout.LayoutParams(80,80); // size of button in dp
params.addRule(RelativeLayout.ALIGN_PARENT_RIGHT, RelativeLayout.TRUE);
params.addRule(RelativeLayout.CENTER_VERTICAL, RelativeLayout.TRUE);
params.setMargins(0, 0, 20, 0);
btnMyLocation.setLayoutParams(params);

Boom! Now you can move it as you want ;)

It's already been explained above.Just a small addition to fabLouis's answer. You may also get your map view from the SupportMapFragment.

        /**
* Move the button
*/
SupportMapFragment mapFragment = (SupportMapFragment) getSupportFragmentManager().
findFragmentById(R.id.map);
View mapView = mapFragment.getView();
if (mapView != null &&
mapView.findViewById(1) != null) {
// Get the button view
View locationButton = ((View) mapView.findViewById(1).getParent()).findViewById(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);
}

If you just want to have location indication enabled (the blue dot) but don't need default My Location button:

mGoogleMap.setMyLocationEnabled(true);
mGoogleMap.getUiSettings().setMyLocationButtonEnabled(false);

This way you can also draw your own button where you want without strange stuff like this mapView.findViewById(1).getParent()).

try this code

private void resetMyPositionButton()
{
Fragment fragment = ( (SupportMapFragment) getSupportFragmentManager().findFragmentById( R.id.map ) );
ViewGroup v1 = (ViewGroup) fragment.getView();
ViewGroup v2 = (ViewGroup)v1.getChildAt(0);
ViewGroup v3 = (ViewGroup)v2.getChildAt(2);
View position =  (View)v3.getChildAt(0);
int positionWidth = position.getLayoutParams().width;
int positionHeight = position.getLayoutParams().height;


//lay out position button
RelativeLayout.LayoutParams positionParams = new RelativeLayout.LayoutParams(positionWidth,positionHeight);
int margin = positionWidth/5;
positionParams.setMargins(margin, 0, 0, margin);
positionParams.addRule(RelativeLayout.CENTER_VERTICAL, RelativeLayout.TRUE);
positionParams.addRule(RelativeLayout.ALIGN_PARENT_LEFT, RelativeLayout.TRUE);
position.setLayoutParams(positionParams);
}

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 Maps Activity.java :-

add this lines of code in onCreate() method,

 SupportMapFragment mapFragment = (SupportMapFragment) getSupportFragmentManager()
.findFragmentById(R.id.map);
mapView = mapFragment.getView();
mapFragment.getMapAsync(this);

and here is onMapReady() code :-

@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);
}


}

I hope, this will solve your problem. Thanks.

I don't fancy seeing these magic view IDs others are using, I suggest using tags to find MapViews children.

Here is my solution for placing the My Location button above the Zoom controls.

// Get map views
View location_button =_mapView.findViewWithTag("GoogleMapMyLocationButton");
View zoom_in_button = _mapView.findViewWithTag("GoogleMapZoomInButton");
View zoom_layout = (View) zoom_in_button.getParent();


// adjust location button layout params above the zoom layout
RelativeLayout.LayoutParams location_layout = (RelativeLayout.LayoutParams) location_button.getLayoutParams();
location_layout.addRule(RelativeLayout.ALIGN_PARENT_TOP, 0);
location_layout.addRule(RelativeLayout.ABOVE, zoom_layout.getId());

This button was moved on to the left side of mapBefore, you could remove old rule of button:

@Override
public void onMapReady(final GoogleMap googleMap) {
this.map = googleMap;
// Show location button
View locationButton = ((View) mapView.findViewById(Integer.parseInt("1")).getParent()).findViewById(Integer.parseInt("2"));
RelativeLayout.LayoutParams rlp = (RelativeLayout.LayoutParams) locationButton.getLayoutParams();
// position on right bottom
Log.l(Arrays.toString(rlp.getRules()), L.getLogInfo());
int[] ruleList = rlp.getRules();
for (int i = 0; i < ruleList.length; i ++) {
rlp.removeRule(i);
}
Log.l(Arrays.toString(rlp.getRules()), L.getLogInfo());
//Do what you want to move this location button:
rlp.addRule(RelativeLayout.CENTER_IN_PARENT, RelativeLayout.TRUE);
rlp.addRule(RelativeLayout.ALIGN_PARENT_LEFT, RelativeLayout.TRUE);
}

I added a line to my fragment android:layout_marginTop="?attr/actionBarSize" It helped me

use this one for bottom-right location

map.setMyLocationEnabled(true);
map.setPadding(0,1600,0,0);
