android - 如何在 Fragment - Android 中使用 PlaceAutoCompleteFragment 小部件？

Question

我在 fragment 中使用 PlaceAutoCompleteFragment。第一次打开 Fragment(其中放置了 PlaceAutoCompleteFragment 的 App fragment )时，它运行良好，就像一个魅力。但是，然后我第二次点击按钮打开 Fragment，它崩溃并出现以下错误。它只工作一次。

FATAL EXCEPTION:
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:

SupportPlaceAutocompleteFragment placeAutocompleteFragment = (SupportPlaceAutocompleteFragment) getActivity().getSupportFragmentManager().
findFragmentById(R.id.place_autocomplete_fragment);

placeAutocompleteFragment.setOnPlaceSelectedListener(new PlaceSelectionListener() {
    @Override
    public void onPlaceSelected(Place place) {
        System.out.println(place.getAddress());
    }

    @Override
    public void onError(Status status) {
    }
});

错误在 onCreateDialog 方法中的这一行，其中布局正在膨胀:

View view = inflater.inflate(R.layout.add_geofence_layout, null);

XML:

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

想知道!为什么这段代码只能运行一次？

DialogFragment 类:

public Dialog onCreateDialog(Bundle savedInstanceState) {
    LayoutInflater inflater = getActivity().getLayoutInflater();
    View view = inflater.inflate(R.layout.add_geofence_layout, null);

    viewHolder = new ViewHolder();
    viewHolder.initializeView(view);
    viewHolder.placeAutocompleteFragment.setOnPlaceSelectedListener(new PlaceSelectionListener() {
        @Override
        public void onPlaceSelected(Place place) {
            System.out.println(place.getAddress());
        }

        @Override
        public void onError(Status status) {

        }
    });
}

注意:- 我在 DialogFragment 中使用 PlaceautoCompleteFragment。如果我在 Activity 中使用它，它工作正常。

不要将 PlaceAutocompleteFragment 直接添加到 fragment 布局中。您需要动态添加 PlaceAutocompleteFragment 并在 onDestroyView() 上将其删除。

layout.xml

        <LinearLayout
            android:id="@+id/placeLayout"
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:orientation="vertical"
            android:visibility="visible">
        </LinearLayout>

添加 PlaceAutocompleteFragment

  PlaceAutocompleteFragment autocompleteFragment=new PlaceAutocompleteFragment();
    FragmentManager fragmentManager = getActivity().getFragmentManager();
    android.app.FragmentTransaction fragmentTransaction = fragmentManager.beginTransaction();
    fragmentTransaction.replace(R.id.placeLayout,autocompleteFragment);
    fragmentTransaction.commit();

在销毁时移除它

@Override
public void onDestroyView() {
    super.onDestroyView();
    if (getActivity() != null) {
        FragmentManager fragmentManager = getActivity().getFragmentManager();
        android.app.FragmentTransaction fragmentTransaction = fragmentManager.beginTransaction();
        fragmentTransaction.remove(autocompleteFragment);
        fragmentTransaction.commit();
    }
