基於兩種不同座標的自動縮放mapView

Question

我可以在谷歌地圖上顯示標記時，他們彼此接近，但當距離很遠時，我只能看到一個緯度。

這裏是我的代碼

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)); 
} 

我需要顯示在映射表座標，只能通過調整基礎上的距離縮放級別來實現。我試過上面的代碼，但它不適合我。

我解決它通過簡單地增加，

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));
