【问题描述】:
我正在使用 osmdroid 库来渲染地图。我有两个间歇性变化的地理点,并希望 org.osmdroid.views.MapView 调整大小和翻译以确保两个点始终可见。我可以轻松地将地图重新居中于两者之间的中间点,但如何设置缩放级别以确保我的两个点可见?
更新
//Getting pickup and destination latitude and longitude
GeoPoint pickupLocation = null;
if (tripRequest.getPickupLat() != null && tripRequest.getPickupLong() != null) {
pickupLocation = new GeoPoint(tripRequest.getPickupLat(), tripRequest.getPickupLong());
}
GeoPoint destinationLocation = null;
if (tripRequest.getDestinationLat() != null && tripRequest.getDestinationLong() != null) {
destinationLocation = new GeoPoint(tripRequest.getDestinationLat(), tripRequest.getDestinationLong());
}
if (destinationLocation != null && pickupLocation != null) {
//Adding destination marker to map
Marker destinationLocationMarker = new Marker(map);
destinationLocationMarker.setPosition(destinationLocation);
destinationLocationMarker.setAnchor(Marker.ANCHOR_CENTER, Marker.ANCHOR_BOTTOM);
destinationLocationMarker.setIcon(context.getResources().getDrawable(R.mipmap.pin_green_small));
map.getOverlays().add(destinationLocationMarker);
//Adding pickup marker to map
Marker pickupLocationMarker = new Marker(map);
pickupLocationMarker.setPosition(pickupLocation);
pickupLocationMarker.setAnchor(Marker.ANCHOR_CENTER, Marker.ANCHOR_BOTTOM);
pickupLocationMarker.setIcon(context.getResources().getDrawable(R.mipmap.pin_red_small));
map.getOverlays().add(pickupLocationMarker);
BoundingBox boundingBox = BoundingBox.fromGeoPoints(Arrays.asList(destinationLocation, pickupLocation));
mapController = map.getController();
mapController.setCenter(boundingBox.getCenter());
mapController.setZoom(10);// I need to set this zoom properly
touchListener = new TouchListener();
map.setOnTouchListener(touchListener);
