我目前正在處理涉及谷歌地圖的應用程序。 我想更改位置標記上方信息的設計。但我無法弄清楚如何做到這一點。如何更改谷歌地圖上標題和片段的設計標記
解釋;
我有這樣的：
，我想這一點：
我有一個藍色的盒子爲圖像設計。但我不知道是否需要使用圖像或編寫代碼使其看起來像圖像。
這裏是我的代碼至今：
MainActivity

public class MainActivity extends FragmentActivity implements LocationListener {
GoogleMap map;
LatLng myPosition;
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
isLocationEnabled(this);
// Getting reference to the SupportMapFragment of activity_main.xml
SupportMapFragment fm = (SupportMapFragment) getSupportFragmentManager().findFragmentById(R.id.map);
// Getting GoogleMap object from the fragment
map = fm.getMap();
// remove geolocation button
map.getUiSettings().setMyLocationButtonEnabled(false);
// Enabling MyLocation Layer of Google Map
map.setMyLocationEnabled(true);
// Getting LocationManager object from System Service LOCATION_SERVICE
LocationManager locationManager = (LocationManager) getSystemService(LOCATION_SERVICE);
// Creating a criteria object to retrieve provider
Criteria criteria = new Criteria();
// Getting the name of the best provider
String provider = locationManager.getBestProvider(criteria, true);
// Getting Current Location
Location location = locationManager.getLastKnownLocation(provider);
if (location != null) {
// Getting latitude of the current location
double latitude = location.getLatitude();
// Getting longitude of the current location
double longitude = location.getLongitude();
// Creating a LatLng object for the current location
LatLng latLng = new LatLng(latitude, longitude);
myPosition = new LatLng(latitude, longitude);
LatLng amsterdam = new LatLng(52.3667, 4.9000);
// create marker

// create and add marker
Marker locationMarker = map.addMarker(markerOptions);
// always show info text
locationMarker.showInfoWindow();
// opening maps zoomed in at current location
map.moveCamera(CameraUpdateFactory.newLatLngZoom(amsterdam, 17.0f));
}
}
@Override

// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.menu_main, menu);
return true;
}

}
}
}
activity_main.xml中
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"

android:layout_width="match_parent"
android:layout_height="match_parent"

對不起提前如果我用草率的編碼或壞實踐。這些文件是我創建功能的遊樂場，以便以後可以將它放入實際的應用程序中。
