android - PlaceAutocompleteFragment : automatically open SearchView

Question

我想在 Activity 加载完成后立即自动点击 fragment 。

fragment 定义为:

 <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.PlaceAutocompleteFragment"
    />

我试过这样做

fragment = findViewById(R.id.place_autocomplete_fragment);

    new Handler().postDelayed(new Runnable() {
        @Override
        public void run() {
            fragment.performClick();
        }
    }, 1000);

但是没用。

有什么方法可以自动点击 fragment 吗？

编辑:在我的例子中， fragment 被膨胀了

//PlaceAutoComplete Search Implementation
    PlaceAutocompleteFragment autocompleteFragment = (PlaceAutocompleteFragment)
            getFragmentManager().findFragmentById(R.id.place_autocomplete_fragment);


    autocompleteFragment.setOnPlaceSelectedListener(new PlaceSelectionListener() {
        @Override
        public void onPlaceSelected(Place place) {
            Log.i(String.valueOf(this), "Place: " + place.getName() + "\nID: " + place.getId());
            String placeId = place.getId();
            try {
                Intent intent = new Intent(PlaceSearch.this, PlaceDetailsFromSearch.class);
                Bundle extras = new Bundle();
                extras.putString("placeID", placeId);
                intent.putExtras(extras);
                startActivity(intent);
            } catch (Exception e) {
                e.printStackTrace();
            }
        }

        @Override
        public void onError(Status status) {
            Log.i(String.valueOf(this), "An error occurred: " + status);
        }
    });

Answer 1

您不能点击 <fragment> .

点击事件只有View可以有。 fragment 不是 View .

你可以点击一个View你的 fragment 膨胀。

@Override
public void onViewCreated(View view, @Nullable Bundle savedInstanceState) {
    super.onViewCreated(view, savedInstanceState);
    
    // some `View` from your fragment
    View searchView = view.findViewById(R.id.searchView); 
    // Dispatch a click event to `searchView` as soon as that view is laid out
    searchView.post(() -> searchView.performClick());
}

更新

因为您正在使用 PlaceAutocompleteFragment来自 Play Services(因此你没有来源)，你可以在你的 Activity 中做这样的事情:

final PlaceAutocompleteFragment autocompleteFragment = (PlaceAutocompleteFragment) getFragmentManager()
        .findFragmentById(R.id.place_autocomplete_fragment);

final View root = autocompleteFragment.getView();
root.post(new Runnable() {
    @Override
    public void run() {
        root.findViewById(R.id.places_autocomplete_search_input)
                .performClick();
    }
});
