抽屉导航后，地图既不可缩放也不可移动

Question

将Google地图添加到抽屉式导航中后，该地图既不可缩放也不可移动。我知道，对此有一些疑问，但我将抽屉式导航作为可单击菜单使用，可通过底部导航栏调用它，这使我的情况略有不同。因此，我需要MapsActivity类中的抽屉式导航。

我的代码- MapsActivity：

public class MapsActivity extends AppCompatActivity implements OnMapReadyCallback,
        NavigationView.OnNavigationItemSelectedListener {

    private GoogleMap mMap;
    public Toolbar toolbar;
    public DrawerLayout drawerLayout;
    public NavController navController;
    public NavigationView accountNavigationView, settingsNavigationView;
    private SeekBar distanceSeekbar;
    private TextView distanceText;

    private FusedLocationProviderClient fusedLocationProviderClient;

    private static int radius;
    static List<Circle> mCircleList;


    @Override
    protected void onCreate(Bundle savedInstanceState) {
        ActivityCompat.requestPermissions(MapsActivity.this, new String[]{Manifest.permission.ACCESS_FINE_LOCATION}, 1);

        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_maps);
        // Obtain the SupportMapFragment and get notified when the map is ready to be used.
        SupportMapFragment mapFragment = (SupportMapFragment) getSupportFragmentManager()
                .findFragmentById(R.id.map);
        mapFragment.getMapAsync(this);

        drawerLayout = findViewById(R.id.drawer_layout);

        // disable slide on drawer navigation
        drawerLayout.setDrawerLockMode(DrawerLayout.LOCK_MODE_LOCKED_CLOSED);

        BottomNavigationView bottomNavigationView = findViewById(R.id.bottom_navigation);
        bottomNavigationView.setOnNavigationItemSelectedListener(new BottomNavigationView.OnNavigationItemSelectedListener() {
            @Override
            public boolean onNavigationItemSelected(@NonNull MenuItem item) {
                switch (item.getItemId()) {
                    case R.id.action_account:
                        Toast.makeText(MapsActivity.this, "Profile", Toast.LENGTH_SHORT).show();
                        drawerLayout.openDrawer(Gravity.LEFT);
                        if (drawerLayout.isDrawerOpen(Gravity.RIGHT)) {
                            drawerLayout.closeDrawer(Gravity.RIGHT);
                        }
                        break;
                    case R.id.action_map:
                        Toast.makeText(MapsActivity.this, "Map", Toast.LENGTH_SHORT).show();
                        startActivity(new Intent(MapsActivity.this, MapsActivity.class));
                        break;
                    case R.id.action_settings:
                        Toast.makeText(MapsActivity.this, "Settings", Toast.LENGTH_SHORT).show();
                        drawerLayout.openDrawer(Gravity.RIGHT);
                        if (drawerLayout.isDrawerOpen(Gravity.LEFT)) {
                            drawerLayout.closeDrawer(Gravity.LEFT);
                        }
                        break;

如何使它再次起作用，以便地图可缩放和移动？感谢您的阅读和任何帮助！

Answer 1

也许您的DrawerLayout与您的地图片段重叠，形成了一个图层，以防止您与地图互动。

尝试在DrawerLayout中添加地图片段以进行测试

如有必要，请评论/隐藏您的Navigation Host Fragment。

如果地图可以按预期工作，则可以创建一个accountNavigationView之类的新视图，然后将地图添加到Navigation Host Fragment中，如下所示：

NavigationUI.setupWithNavController(mapView, navController);
