java code-

try {
            MapsInitializer.initialize(getApplicationContext());
        } catch (GooglePlayServicesNotAvailableException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }

        switch (GooglePlayServicesUtil.isGooglePlayServicesAvailable(getApplicationContext()) )
        {
        case ConnectionResult.SUCCESS:

            mapView = (MapView)findViewById(R.id.map);
            mapView.onCreate(savedInstanceState);
            // Gets to GoogleMap from the MapView and does initialization stuff
            if(mapView!=null)
            {
                map = mapView.getMap();
                map.getUiSettings().setMyLocationButtonEnabled(false);
                map.setMyLocationEnabled(true);
                CameraUpdate cameraUpdate = CameraUpdateFactory.newLatLngZoom(locationPosition, 10);
                map.animateCamera(cameraUpdate);
                map.setMapType(GoogleMap.MAP_TYPE_NORMAL);
            }
            break;
        case ConnectionResult.SERVICE_MISSING: 

            break;
        case ConnectionResult.SERVICE_VERSION_UPDATE_REQUIRED: 

            break;
        default: Toast.makeText(getApplicationContext(), GooglePlayServicesUtil.isGooglePlayServicesAvailable(getApplicationContext()), Toast.LENGTH_SHORT).show();
        }

        CameraPosition cameraPosition = new CameraPosition.Builder()
        .target(locationPosition).zoom(10).bearing(0) // Sets the orientation of the camera to east
        .tilt(70)    // Sets the tilt of the camera to 30 degrees
        .build();    // Creates a CameraPosition from the builder
        map.setBuildingsEnabled(true);
        map.setMyLocationEnabled(true);
        map.setMapType(GoogleMap.MAP_TYPE_NORMAL);
        map.animateCamera(CameraUpdateFactory.newCameraPosition(cameraPosition));
        map.addMarker(new MarkerOptions() .position(locationPosition).icon(BitmapDescriptorFactory.fromResource(R.drawable.icon_marker)));

推荐答案

我有一个非常类似的问题（我坚持使用MapView即使在此时已被弃用）。
这是我的问题，也是我的答案：

I had a very similar problem(I insisted working with the MapView even though it is deprecated at this point). Here it is my issue and also my answer: Android Map loading very slow/not loading at all in started activity until clicking on it

你需要实现以下方法：
OnResume（）;的onPause（）;的onDestroy（）; onLowMemory（）;

You need to implement the following methods: OnResume(); OnPause(); onDestroy(); onLowMemory();

希望它有帮助。
