I want to automatically click on a fragment as soon as the activity is done loading.

The fragment definition is:

 <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"
    />

I have tried doing this

fragment = findViewById(R.id.place_autocomplete_fragment);

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

but it didnt work.

Is there any way to click automatically on a fragment?

EDIT: In my case, the fragment is inflated by

//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);
        }
    });

You cannot click on a <fragment>.

Click event is something that only View can have. Fragment is not a View.

You can click on a View that your fragment inflates.

@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());
}

Update

Because you are using PlaceAutocompleteFragment which is from Play Services (thus you do not have sources), you can do something like this in your activity:

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();
    }
});
