Question

我可以在Google地图上彼此靠近时显示标记，但是当它们之间的距离很高时，我只能看到一个lat＆amp; lon。

这是我的代码

   public void onMapReady(GoogleMap googleMap) {
    mMap = googleMap;

    LatLng google_api_lat_lon = new LatLng(lat, lon);
    float zoomLevel = 16.0f;
    Marker markerAPILocation = mMap.addMarker(new MarkerOptions().position(google_api_lat_lon).title(title).icon(BitmapDescriptorFactory.fromResource(R.drawable.saved_locaitons)));
    markerAPILocation.showInfoWindow();
    mMap.setMyLocationEnabled(true);
    mMap.moveCamera(CameraUpdateFactory.newLatLngZoom(google_api_lat_lon, zoomLevel));
    if (ActivityCompat.checkSelfPermission(this, Manifest.permission.ACCESS_FINE_LOCATION) != PackageManager.PERMISSION_GRANTED && ActivityCompat.checkSelfPermission(this, Manifest.permission.ACCESS_COARSE_LOCATION) != PackageManager.PERMISSION_GRANTED) {
        // TODO: Consider calling
        //    ActivityCompat#requestPermissions
        // here to request the missing permissions, and then overriding
        //   public void onRequestPermissionsResult(int requestCode, String[] permissions,
        //                                          int[] grantResults)
        // to handle the case where the user grants the permission. See the documentation
        // for ActivityCompat#requestPermissions for more details.
        return;
    }
    //  mMap.setMyLocationEnabled(true);
    mMap.getUiSettings().setMapToolbarEnabled(false);
    mMap.getUiSettings().setZoomControlsEnabled(true);
    mMap.getUiSettings().setScrollGesturesEnabled(false);
    mMap.moveCamera(CameraUpdateFactory.newLatLngZoom(google_api_lat_lon, zoomLevel));
}

我需要在地图中显示两个坐标，只有通过根据距离调整缩放级别才能实现。我试过上面的代码，但它不适合我。

我通过简单地添加

解决了这个问题

   LatLngBounds.Builder builder = new LatLngBounds.Builder();
    builder.include(google_api_lat_lon);
    builder.include(current_lat_lon);
    LatLngBounds bounds = builder.build();
    mMap.animateCamera(CameraUpdateFactory.newLatLngBounds(bounds, 10));

自动缩放mapView基于两个不同的坐标
