Question

目前我在Android应用程序中使用谷歌地图v2，我遇到了地图的配色方案定制问题。我在网上看到了javascript可能https://developers.google.com/maps/customize和http://jsfiddle.net/SQvej/ js中的一些例子

var settingsItemsMap = {
zoom: 12,
center: new google.maps.LatLng(40.768516981, -73.96927308),
zoomControlOptions: {
  style: google.maps.ZoomControlStyle.LARGE
},
styles:[
    { featureType: "water", stylers: [ { hue: "#F4B741"} ] },
    { featureType: "road", stylers: [ { hue: "#ff0000" } ] }
],
mapTypeId: google.maps.MapTypeId.ROADMAP
};
var map = new google.maps.Map(document.getElementById('map_canvas'), settingsItemsMap );

但没有找到Android地图的解决方案，有什么建议吗？

Answer 1

这在Android API v2中是不可能的。你唯一可以改变的是地图类型。

我只能建议在gmaps-api-issues上发布功能请求。

您可以使用MapBox的API来实现这一目标。首先，注册一个帐户，按照您需要的方式设计地图，然后获取 MapID 和访问令牌。

接下来，复制此课程

public class MapBoxOnlineTileProvider extends UrlTileProvider {

public final String TAG = this.getClass().getCanonicalName();
private static final String FORMAT;

static {
    FORMAT = "%s://api.tiles.mapbox.com/v4/%s/%d/%d/%d.png?access_token=%s";
}


private boolean mHttpsEnabled;
private String mMapIdentifier;
private String mAccessToken;


public MapBoxOnlineTileProvider(String mapIdentifier, String accessToken) {
    this(mapIdentifier, accessToken, false);
}

public MapBoxOnlineTileProvider(String mapIdentifier, String accessToken, boolean https) {
    super(256, 256);

    this.mHttpsEnabled = https;
    this.mMapIdentifier = mapIdentifier;
    this.mAccessToken = accessToken;
}


/**
 * The MapBox map identifier being used by this provider.
 *
 * @return the MapBox map identifier being used by this provider.
 */
public String getMapIdentifier() {
    return this.mMapIdentifier;
}

/**
 * Sets the identifier of the MapBox hosted map you wish to use.
 *
 * @param aMapIdentifier the identifier of the map.
 */
public void setMapIdentifier(String aMapIdentifier) {
    this.mMapIdentifier = aMapIdentifier;
}

/**
 * Whether this provider will use HTTPS when requesting tiles.
 *
 * @return {@link true} if HTTPS is enabled on this provider.
 */
public boolean isHttpsEnabled() {
    return this.mHttpsEnabled;
}

/**
 * Sets whether this provider should use HTTPS when requesting tiles.
 *
 * @param enabled
 */
public void setHttpsEnabled(boolean enabled) {
    this.mHttpsEnabled = enabled;
}

/**
 * The MapBox Acces Token found in Account Settings.
 */
public String getAccessToken() {
    return mAccessToken;
}

public void setAccessToken(String mAccessToken) {
    this.mAccessToken = mAccessToken;
}

@Override
public URL getTileUrl(int x, int y, int z) {
    try {
        String protocol = this.mHttpsEnabled ? "https" : "http";
        final String url = String.format(FORMAT,
                protocol, this.mMapIdentifier, z, x, y, this.mAccessToken);
        Log.d(TAG, url);
        return new URL(url);
    } catch (MalformedURLException e) {
        return null;
    }
} }

现在，在您的活动中，地图准备就绪后：

String myMapID = "yourMapID";
String accesToken = "yourAccesToken";
MapBoxOnlineTileProvider provider = new   MapBoxOnlineTileProvider(myMapID, accesToken);
map.addTileOverlay(new TileOverlayOptions()
                .tileProvider(provider));

结果：

从这里创建风格

https://mapstyle.withgoogle.com/

然后将该json保存在RAW文件夹下，然后在您的代码中调用该样式，如此

MapStyleOptions style = MapStyleOptions.loadRawResourceStyle(getActivity(), R.raw.my_map_style);
        googleMap.setMapStyle(style);

Answer 4

如果要求只是调暗或改变地图的整体颜色，那么您可以使用图块叠加。这将在地图上创建部分透明的图层（在本例中为绿色）。它位于瓷砖正上方，因此标记和其他对象不受影响。

@Override
public void onMapReady(GoogleMap googleMap) {
    TileProvider coordTileProvider = new CoordTileProvider(getActivity());
    map.addTileOverlay(new TileOverlayOptions().tileProvider(coordTileProvider));       
}

班级CoordTileProvider是：

public static class CoordTileProvider implements TileProvider {

    private static final int TILE_SIZE_DP = 256;

    private final float mScaleFactor;

    private final Bitmap mBorderTile;

    public CoordTileProvider(Context context) {
        /* Scale factor based on density, with a 0.2 multiplier to increase tile generation
         * speed */
        mScaleFactor = context.getResources().getDisplayMetrics().density * 0.2f;
        Paint paint = new Paint();
        paint.setColor(Color.argb(150,200,255,200));
        mBorderTile = Bitmap.createBitmap((int) (TILE_SIZE_DP * mScaleFactor),
                (int) (TILE_SIZE_DP * mScaleFactor), android.graphics.Bitmap.Config.ARGB_8888);
        Canvas canvas = new Canvas(mBorderTile);
        canvas.drawRect(0, 0, TILE_SIZE_DP * mScaleFactor, TILE_SIZE_DP * mScaleFactor,
                paint);
    }

    @Override
    public Tile getTile(int x, int y, int zoom) {
        Bitmap coordTile = drawTileCoords(x, y, zoom);
        ByteArrayOutputStream stream = new ByteArrayOutputStream();
        coordTile.compress(Bitmap.CompressFormat.PNG, 0, stream);
        byte[] bitmapData = stream.toByteArray();
        return new Tile((int) (TILE_SIZE_DP * mScaleFactor),
                (int) (TILE_SIZE_DP * mScaleFactor), bitmapData);
    }

    private Bitmap drawTileCoords(int x, int y, int zoom) {
        Bitmap copy = null;
        synchronized (mBorderTile) {
            copy = mBorderTile.copy(android.graphics.Bitmap.Config.ARGB_8888, true);
        }
        return copy;
    }
}

您只能更改地图样式。
