谷歌地图在使用 ViewPager 的 Horizo​​ntalScrollView 中不起作用

Question

我正在尝试将谷歌地图添加到 ViewPager 的一项中，即 Horizo​​ntalScrollView。我想在我的项目中显示商店的多个位置，因此使用 Horizo​​ntalScrollView 从左到右滚动仅用于 googlemap 和 viewpager 内的完整页面。在 viewpager 中没有谷歌地图的情况下，一切都可以正常工作，但是当我添加谷歌地图来查看寻呼机时，我的应用程序崩溃了。

这是我的 logcat 和我迄今为止所做的努力。

My Pastebin

我很惊讶为什么这里是授权失败，但是在评论 viewpager 部分之后，它的工作就像魅力并显示正确的地图和其他东西。

注意： ViewPager 和 google map 都可以使用，但不能同时使用。

这3天我的搜索：1,2,3,4,5,6,7,8,10,@987654

上面给出的一些解决方案很棒，但我不知道为什么这些都不适用于我的情况。

请帮助我。

感谢和问候： 阿奇

您可以在您的 api 演示中查看参考。放在目录中 日食：<installation-directory>/sdk/extras/google/google-play-services/samples/maps 你必须导入项目，然后你才能看到所有的东西。

我通过在 viewpager 中添加 mapview 来解决这个问题：

  LatLng StartPoint = new LatLng(latitude, longitude);
        LatLng EndPoint = new LatLng(28.474388, 77.503990);

        mapView.onCreate(bundle);
        mapView.onResume();  
        GoogleMap map = mapView.getMap();

        map.getUiSettings().setMyLocationButtonEnabled(false);
        map.setMyLocationEnabled(true);

        MapsInitializer.initialize(getActivity());

        // Updates the location and zoom of the MapView
        Marker startPoint = map.addMarker(new MarkerOptions().position(
                StartPoint).title("startPoint"));
        Marker endPoint = map.addMarker(new MarkerOptions().position(EndPoint)
                .title("endPoint"));

        // Move the camera instantly to EndPoint with a zoom of 15.
        map.moveCamera(CameraUpdateFactory.newLatLngZoom(EndPoint, 10));

        // Zoom in, animating the camera.
        map.animateCamera(CameraUpdateFactory.zoomTo(10), 2000, null);

现在一切正常。

fragment 是 viewPagerFragment 的实例

在xml中

<LinearLayout
android:id="@+id/map"
android:layout_width="match_parent"
android:layout_height="250dp" />
