實作前準備

要實作到這一步，就需要分別拿到google APIKEY 和百度的APIKEY然后在你的應用中進行配置，google地圖和百度地圖的詳細接入方法就在上面的文章中，當然你也可以去看看他們的官方檔案，系統的學習，
好，那直接進入主題

一個小demo

為了減少我們在一個頁面中進行兩種地圖的切換代碼和兼容性考慮，我們這邊不建議使用SupportMapFragment 的方式來顯示google地圖，這里強烈推薦使用goole提供的實體化MapView的方式來載入google地圖
使用也非常簡單，直接來看代碼：

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();
//        //設定地圖模式為衛星地圖
        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();
    }
}

代碼就這么多來看效果圖（記得在Manifest檔案中將APIKEY進行配置）
在這里插入圖片描述

這里有個坑MapView生命周期注冊非常重要，如果不設定生命周期一運行顯示空白，只顯示logo

接入思路

我這里同時接入是先實體化google的MapView和百度地圖的Mapview，然后將它們放入我當前activity所對應布局中的指定父容器中，先都設定visible為gone,然后根據獲取SharedPreferences中我指定的變數，默認加載上一次用戶退出時使用的是google地圖還是百度地圖，當用戶點擊地圖切換的圖示時，可以對當前頁面要顯示的地圖進行切換，這時設定選中的所對應的地圖的visible為可見，這樣我們在切換地圖時就不會出現卡頓或突然黑一下螢屏的情況，提高用戶體驗，最后將新的變數值存盤到SharedPreferences中方便下次呼叫
