android - 如何在 fragment 中使用 PlaceAutoCompleteFragment 小部件

Question

我在 Fragment 中使用 PlaceAutoCompleteFragment。第一次打开 Fragment(放置 PlaceAutoCompleteFragment 的 App fragment )时，它工作得很好，就像一个魅力。

但是，当我第二次按下按钮打开 Fragment 时，它崩溃并出现以下错误。它只工作一次。

致命异常:

android.view.InflateException: Binary XML file line #64: Error inflating class fragment Caused by: java.lang.IllegalArgumentException: Binary XML file line #64: Duplicate id 0x7f0d0094, tag null, or parent id 0xffffffff with another fragment for com.google.android.gms.location.places.ui.PlaceAutocompleteFragment

这就是我使用它的方式，用于搜索位置

public View onCreateView(LayoutInflater inflater,  ViewGroup container, Bundle savedInstanceState) {

            View view = inflater.inflate(R.layout.parkingview_fragment, container, false);

            mapFragment = (SupportMapFragment) this.getChildFragmentManager().findFragmentById(R.id.map_parkingview);
            mapFragment.getMapAsync(this);

          // For Search location
          PlaceAutocompleteFragment  autocompleteFragment = null;

            if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.HONEYCOMB) {

                    autocompleteFragment = (PlaceAutocompleteFragment) getActivity().getFragmentManager().findFragmentById(R.id.place_fragment_parkingview);
            }

        autocompleteFragment.setOnPlaceSelectedListener(this);
        autocompleteFragment.setHint("Search a Location");
//        autocompleteFragment.setBoundsBias(BOUNDS_MOUNTAIN_VIEW);

        return view;

    }

XML:

 <fragment
        android:id="@+id/place_fragment_parkingview"
        android:name="com.google.android.gms.location.places.ui.PlaceAutocompleteFragment"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"/>

动态声明您的 fragment 将解决问题。

<FrameLayout
android:id="@+id/fragment_content"
android:layout_width="match_parent"
android:layout_height="wrap_content"
/>

并在 CreateView 上更新你的 fragment

SupportPlaceAutocompleteFragment autocompleteFragment = new SupportPlaceAutocompleteFragment();
android.support.v4.app.FragmentManager fm = getFragmentManager();
FragmentTransaction ft = fm.beginTransaction();
ft.replace(R.id.fragment_content, autocompleteFragment);
ft.commit();
