放置自動完成整合

Google Places API for Android 中的自動填充功能可為使用者提供位置預測。當使用者在搜尋框中輸入內容時，自動填充功能會根據使用者的查詢顯示位置。

AutoCompleteActivity.java

private TextView txtSelectedPlaceName;

@Override
protected void onCreate(@Nullable Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_autocomplete);

    txtSelectedPlaceName = (TextView) this.findViewById(R.id.txtSelectedPlaceName);

    PlaceAutocompleteFragment autocompleteFragment = (PlaceAutocompleteFragment)
            getFragmentManager().findFragmentById(R.id.fragment_autocomplete);

    autocompleteFragment.setOnPlaceSelectedListener(new PlaceSelectionListener() {
        @Override
        public void onPlaceSelected(Place place) {
            Log.i(LOG_TAG, "Place: " + place.getName());
            txtSelectedPlaceName.setText(String.format("Selected places : %s  - %s" , place.getName(), place.getAddress()));
        }

        @Override
        public void onError(Status status) {
            Log.i(LOG_TAG, "An error occurred: " + status);
            Toast.makeText(AutoCompleteActivity.this, "Place cannot be selected!!", Toast.LENGTH_SHORT).show();
        }
    });

}

}
