android高德地图源码,Android Fragment 导航

以下是Android Fragment 导航的高德地图源码，参考下面的代码：

1. 在build.gradle文件中添加高德地图的依赖：

implementation 'com.amap.api:3dmap:latest_version'
implementation 'com.amap.api:navi:latest_version'
implementation 'com.amap.api:location:latest_version'
implementation 'com.amap.api:safety:latest_version'

2. 在xml布局文件中添加MapView：

<com.amap.api.maps.MapView
    android:id="@+id/map_view"
    android:layout_width="match_parent"
    android:layout_height="match_parent" />

3. 在Fragment中初始化MapView：

public class MapFragment extends Fragment implements OnMapReadyCallback {
    private MapView mapView;
    private AMap aMap;

    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container,
                             Bundle savedInstanceState) {
        View view = inflater.inflate(R.layout.fragment_map, container, false);
        mapView = view.findViewById(R.id.map_view);
        mapView.onCreate(savedInstanceState);
        mapView.getMapAsync(this);
        return view;
    }

    @Override
    public void onMapReady(AMap aMap) {
        this.aMap = aMap;
        // 设置地图属性
        aMap.setMapType(AMap.MAP_TYPE_NORMAL);
        aMap.moveCamera(CameraUpdateFactory.zoomTo(15));
    }

    @Override
    public void onResume() {
        super.onResume();
        mapView.onResume();
    }

    @Override
    public void onPause() {
        super.onPause();
        mapView.onPause();
    }

    @Override
    public void onDestroy() {
        super.onDestroy();
        mapView.onDestroy();
    }
}

4. 实现Fragment导航功能，在Activity中调用导航方法：

public class MainActivity extends AppCompatActivity {
    private MapView mapView;
    private AMap aMap;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        mapView = findViewById(R.id.map_view);
        mapView.onCreate(savedInstanceState);
        mapView.getMapAsync(new OnMapReadyCallback() {
            @Override
            public void onMapReady(AMap aMap) {
                MainActivity.this.aMap = aMap;
                // 设置地图属性
                aMap.setMapType(AMap.MAP_TYPE_NORMAL);
                aMap.moveCamera(CameraUpdateFactory.zoomTo(15));
            }
        });

        Button btnNavigate = findViewById(R.id.btn_navigate);
        btnNavigate.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                startNavigate();
            }
        });
    }

    private void startNavigate() {
        NaviLatLng start = new NaviLatLng(39.989614, 116.481763);
        NaviLatLng end = new NaviLatLng(39.983456, 116.315495);
        List<NaviLatLng> wayPoints = new ArrayList<>();
        wayPoints.add(new NaviLatLng(39.925846, 116.432765));
        wayPoints.add(new NaviLatLng(39.90781, 116.412476));
        wayPoints.add(new NaviLatLng(39.904131, 116.406501));

        AmapNavi.getInstance(this).calculateDriveRoute(start, end, wayPoints, PathPlanningStrategy.DRIVING_MULTIPLE_ROUTES_AVOID_CONGESTION, new OnCalculateRouteListener() {
            @Override
            public void onCalculateRouteSuccess(int[] ints) {
                Intent intent = new Intent(MainActivity.this, RoutePlanActivity.class);
                intent.putExtra("gps", true);
                startActivity(intent);
            }

            @Override
            public void onCalculateRouteFailure(int i) {
                Toast.makeText(MainActivity.this, "路线计算失败", Toast.LENGTH_SHORT).show();
            }

            @Override
            public void onNaviRouteNotify(int i, String s) {

            }
        });
    }

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

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

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