Android Google Map开发指南(三)百度地图、谷歌地图自如切换

如果你是刚开始接触谷歌地图的话，推荐你先看一下文章：

Android Google Map 开发指南（一）解决官方demo显示空白只展示google logo问题

如果你刚接触百度地图的话，推荐你可以看一下：

Android百度地图SDK最新详细使用（包含demo）

目录

废话不多说，先来一波效果图：

在这里插入图片描述

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";

    @Override
    protected 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);
    }

    @Override
    public 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));
    }

    @Override
    public 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);
    }

    @Override
    protected void onResume() {
        super.onResume();
        mMapView.onResume();
    }

    @Override
    protected void onStart() {
        super.onStart();
        mMapView.onStart();
    }

    @Override
    protected void onStop() {
        super.onStop();
        mMapView.onStop();
    }



    @Override
    protected void onPause() {
        mMapView.onPause();
        super.onPause();
    }

    @Override
    protected void onDestroy() {
        mMapView.onDestroy();
        super.onDestroy();
    }

    @Override
    public 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）
在这里插入图片描述

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
