Android - android.view.InflateException 错误 第二次转到 google 地图时

Question

我在我的 android 应用程序中实现了一个 google 地图，它第一次运行良好。但是当我第二次尝试进入它时，应用程序崩溃了。

我发现我必须以编程方式声明 supportFragment 而无需在 xml 中进行操作。 但是堆栈溢出中的解决方案对我不起作用，因为我正在 class 中访问我的 google 映射，它扩展到 PagerAdapter 。它不支持 getChildFragmentManager()。我该如何克服这个问题？

我的class

    public class ViewPageAdapter extends PagerAdapter {

    private Fragment fragmentActivity;

    public ViewPageAdapter(ArrayList<BaseElement> item, int page,
                Activity activity, Fragment fragmentActivity) {
            super();
            this.item = item;
            this.page = page;
            this.activity = activity;
            this.fragmentActivity = fragmentActivity;
            inflater = (LayoutInflater) activity
                    .getSystemService(Context.LAYOUT_INFLATER_SERVICE);

            this.imageLoader = new ImageLoader(activity);
        }

    @Override
        public Object instantiateItem(ViewGroup container, int position) {

    View view = null;


if (page == Element.THEATER_DETAIL.getType()) {


    GoogleMap googleMap = null;

                SupportMapFragment fm = (SupportMapFragment) fragmentActivity
                        .getFragmentManager().findFragmentById(R.id.map);


                googleMap = fm.getMap();



                googleMap.addMarker(new MarkerOptions().position(
                        new LatLng(7.421226f, 80.401264f)).title("Hello world"));

                final LatLng SRILANKA = new LatLng(7.421226,80.401264);

                CameraPosition cameraPosition = new CameraPosition.Builder()
                .target(SRILANKA)      // Sets the center of the map to SRILANKA
                .zoom(10)                   // Sets the zoom
                .bearing(360)                // Sets the orientation of the camera to east
                .tilt(30)                   // Sets the tilt of the camera to 30 degrees
                .build();                   // Creates a CameraPosition from the builder
                googleMap.animateCamera(CameraUpdateFactory.newCameraPosition(cameraPosition));

            }

XML

<fragment 
          android:id="@+id/map"
          android:layout_width="match_parent"
          android:layout_height="match_parent"
          android:layout_weight="1"
          android:name="com.google.android.gms.maps.SupportMapFragment"/>

Answer 1

你添加视图了吗？你应该在 instantiateItem 函数中添加视图，

     LayoutInflater inflater = (LayoutInflater) activity.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
        View view = inflater.inflate(R.layout.your_layout_name, null);

然后继续你的代码。
