實現前準備

要實現到這一步，就需要分別拿到google APIKEY 和百度的APIKEY然後在你的應用中進行設定，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程式碼和相容性考慮，我們這邊不建議使用SupportMapFragment 的方式來顯示google地圖，這裡強烈推薦使用goole提供的範例化MapView的方式來載入google地圖
使用也非常簡單，直接來看程式碼：

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();
    }
}

程式碼就這麼多來看效果圖（記得在Manifest檔案中將APIKEY進行設定）
在這裡插入圖片描述

這裡有個坑MapView生命週期註冊非常重要，如果不設定生命週期一執行顯示空白，只顯示logo

接入思路

我這裡同時接入是先範例化google的MapView和百度地圖的Mapview，然後將它們放入我當前activity所對應佈局中的指定父容器中，先都設定visible為gone,然後根據獲取SharedPreferences中我指定的變數，預設載入上一次使用者退出時使用的是google地圖還是百度地圖，當使用者點選地圖切換的圖示時，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幕的情況，提高使用者體驗，最後將新的變數值儲存到SharedPreferences中方便下次呼叫
