实现前准备

要实现到这一步，就需要分别拿到google APIKEY 和百度的APIKEY然后在你的应用中进行配置，google地图和百度地图的详细接入方法就在上面的文章中，当然你也可以去看看他们的官方文档，系统的学习。
好，那直接进入主题

一个小demo

为了减少我们在一个页面中进行两种地图的切换代码和兼容性考虑，我们这边不建议使用SupportMapFragment 的方式来显示google地图，这里强烈推荐使用goole提供的实例化MapView的方式来载入google地图
使用也非常简单，直接来看代码：

public class SecondActivity extends AppCompatActivity implements OnMapReadyCallback {private MapView mMapView;private static final String MAPVIEW_BUNDLE_KEY = "MapViewBundleKey";@Overrideprotected void onCreate( Bundle savedInstanceState) {super.onCreate(savedInstanceState);GoogleMapOptions options = new GoogleMapOptions();
//        //设置地图模式为卫星地图options.mapType(GoogleMap.MAP_TYPE_NORMAL);options.zoomControlsEnabled(true);mMapView = new MapView(this, options);setContentView(mMapView);mMapView.onCreate(null);mMapView.getMapAsync(this);}@Overridepublic void onMapReady(GoogleMap map) {double lat = 39.937795;double lng = 116.387224;LatLng appointLoc = new LatLng(lat, lng);map.addMarker(new MarkerOptions().position(appointLoc).title("Marker"));map.moveCamera(CameraUpdateFactory.newLatLng(appointLoc));}@Overridepublic void onSaveInstanceState(Bundle outState) {super.onSaveInstanceState(outState);Bundle mapViewBundle = outState.getBundle(MAPVIEW_BUNDLE_KEY);if (mapViewBundle == null) {mapViewBundle = new Bundle();outState.putBundle(MAPVIEW_BUNDLE_KEY, mapViewBundle);}mMapView.onSaveInstanceState(mapViewBundle);}@Overrideprotected void onResume() {super.onResume();mMapView.onResume();}@Overrideprotected void onStart() {super.onStart();mMapView.onStart();}@Overrideprotected void onStop() {super.onStop();mMapView.onStop();}@Overrideprotected void onPause() {mMapView.onPause();super.onPause();}@Overrideprotected void onDestroy() {mMapView.onDestroy();super.onDestroy();}@Overridepublic void onLowMemory() {super.onLowMemory();mMapView.onLowMemory();}
}

代码就这么多来看效果图（记得在Manifest文件中将APIKEY进行配置）

这里有个坑MapView生命周期注册非常重要，如果不设置生命周期一运行显示空白，只显示logo

接入思路

我这里同时接入是先实例化google的MapView和百度地图的Mapview，然后将它们放入我当前activity所对应布局中的指定父容器中，先都设置visible为gone,然后根据获取SharedPreferences中我指定的变量，默认加载上一次用户退出时使用的是google地图还是百度地图，当用户点击地图切换的图标时，可以对当前页面要显示的地图进行切换，这时设置选中的所对应的地图的visible为可见，这样我们在切换地图时就不会出现卡顿或突然黑一下屏幕的情况，提高用户体验，最后将新的变量值存储到SharedPreferences中方便下次调用
