Pre-populate address in PlaceAutocomplete (Google Api)

Question

I have implemented PlaceAutocomplete in my android project everything is working fine, but as per its working when call this(PlaceAutocomplete) activity is appear empty

Using this code to start Code:

Intent intent =new PlaceAutocomplete.IntentBuilder(PlaceAutocomplete.MODE_OVERLAY).build(getActivity());
startActivityForResult(intent, 0);

But as per My project requirement I need to pre-populate the previously selected address here(e.g. i have selected any address in first time and set that address into any Text Field, now user want to edit that address but if user click on the text view auto complete appears empty).

I have tried a lot but did not find any solution.
It there any way to achieve that in android???

Answer 1

This is working for me.

implementation 'com.google.android.libraries.places:places:2.3.0'

For Intent

List<Place.Field> fields = Arrays.asList(
            Place.Field.ID,
            Place.Field.NAME,
            Place.Field.ADDRESS,
            Place.Field.LAT_LNG);
    // Start the autocomplete intent.
    Intent intent = new Autocomplete.IntentBuilder(AutocompleteActivityMode.OVERLAY, fields)
            .setInitialQuery(addressTexts)
            .build(getActivity());
    startActivityForResult(intent, AUTOCOMPLETE_REQUEST_CODE);

Now it has .setInitialQuery(<your address texts>) method for initial query.

Found It.

I was expecting that answer earlier.

There is method in PlaceAutocomplete.IntentBuilder class i.e. zzfd(@Nullable String var1).

It need a String value(your address if you want to prepopulate). So you can use this while calling startActivityForResult().

Code Will be Like:

Intent intent =new PlaceAutocomplete.IntentBuilder(PlaceAutocomplete.MODE_OVERLAY)
                                    .zzfd(your_text_View.getText().toString())
                                    .build(getActivity());
startActivityForResult(intent, 1);

You can pass null in zzfd() if you do not have address in starting.

You send address also on "initial_query" KEY, that will also work same.

For example:

Intent intent =new PlaceAutocomplete.IntentBuilder(PlaceAutocomplete.MODE_OVERLAY)
                                   .build(getActivity());
if (!TextUtils.isEmpty(your_text_View.getText().toString())) {
intent.putExtra("initial_query", (your_text_View.getText().toString());
} else {
   intent.removeExtra("initial_query");
}
startActivityForResult(intent, 1);

Creating a custom auto complete text view for places:

XML:

<AutoCompleteTextView
                    android:id="@+id/location_Et"
                    android:layout_width="match_parent"
                    android:layout_height="wrap_content"
                    android:layout_alignParentStart="true"
                    android:layout_toStartOf="@+id/textCancel"
                    android:background="@drawable/search_box_bg"
                    android:drawablePadding="8dp"
                    android:drawableStart="@drawable/ic_search_grey_700_24dp"
                    android:ellipsize="end"
                    android:focusableInTouchMode="true"
                    android:hint="Search Location"
                    android:imeOptions="actionSearch"
                    android:inputType="textNoSuggestions"
                    android:lines="1"
                    android:paddingBottom="10dp"
                    android:paddingTop="10dp"
                    android:textColor="@color/standard_gray"
                    android:textCursorDrawable="@null"
                    android:textSize="18sp"
                    app:fontFileName="ProximaNova-Regular.otf"/>

In Activity:

locationEt = (AutoCompleteTextView) findViewById(R.id.location_Et);

        final PlacesAutoCompleteAdapter adapterPopUpDestination = new PlacesAutoCompleteAdapter(CustomLocationSelectionActivity.this, R.layout.autocomplete_list_text);
        locationEt.setAdapter(adapterPopUpDestination);

        locationEt.setOnItemClickListener(new AdapterView.OnItemClickListener() {
            @Override
            public void onItemClick(AdapterView<?> adapterView, View view, int i, long l) {

                String address = adapterPopUpDestination.getItem(i);

            }
        });

Adapter:

public class PlacesAutoCompleteAdapter extends ArrayAdapter<String> implements Filterable {
    public static final String LOG_TAG = "ImpactForce";
    String textaddress;
    private ArrayList<String> resultList = new ArrayList<String>();
    private LayoutInflater inflater;
    private ViewHolder holder;

    public PlacesAutoCompleteAdapter(Context context, int textViewResourceId) {
        super(context, textViewResourceId);

        inflater = (LayoutInflater) context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
    }

    @Override
    public int getCount() {
        return resultList.size();
    }

    @Override
    public String getItem(int index) {
        if (resultList.size() > index) {
            return resultList.get(index);
        }
        return "";
    }

        if (convertView == null) {
            convertView = inflater.inflate(R.layout.autocomplete_list_text, parent, false);
            holder = new ViewHolder();

            holder.addressTitle = (TextView) convertView.findViewById(R.id.textViewTitleHeader);
            holder.address = (TextView) convertView.findViewById(R.id.textViewTitleSub);
            convertView.setTag(holder);
        } else {
