如何实现 PlaceAutocompleteFragment 和 PlaceAutocompleteActivity 来获取地点详细信息

我在用谷歌地方 https://developers.google.com/places/android-api/?hl=en获取地点详细信息。 Google 提供了不同的方式来实现 Google Place API 来获取地点详细信息。不同的方式如下放置自动完成片段 , 放置自动完成活动。如何区分这些以及如何使用 Google place API 来获取地点详细信息。

首先需要API key https://developers.google.com/places/android-api/signup并启用 Google Place API 来搜索和获取地点详细信息。 将您的 API 密钥添加到您的应用清单中，需要将 YOUR_API_KEY 替换为您自己的 API 密钥：

<application>
  ...
  <meta-data
      android:name="com.google.android.geo.API_KEY"
      android:value="YOUR_API_KEY"/>
</application>

1) 放置自动完成片段

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.PlaceAutocompleteFragment"
  />

Java:

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

/*
* The following code example shows setting an AutocompleteFilter on a PlaceAutocompleteFragment to
* set a filter returning only results with a precise address.
*/
AutocompleteFilter typeFilter = new AutocompleteFilter.Builder()
        .setTypeFilter(AutocompleteFilter.TYPE_FILTER_ADDRESS)
        .build();
autocompleteFragment.setFilter(typeFilter);

autocompleteFragment.setOnPlaceSelectedListener(new PlaceSelectionListener() {
    @Override
    public void onPlaceSelected(Place place) {
        // TODO: Get info about the selected place.
        Log.i(TAG, "Place: " + place.getName());//get place details here
    }

    @Override
    public void onError(Status status) {
        // TODO: Handle the error.
        Log.i(TAG, "An error occurred: " + status);
    }
});

Output:

2) 放置自动完成活动

private void callPlaceAutocompleteActivityIntent() {
    try {
        Intent intent =
                new PlaceAutocomplete.IntentBuilder(PlaceAutocomplete.MODE_FULLSCREEN)
                        .build(this);
        startActivityForResult(intent, PLACE_AUTOCOMPLETE_REQUEST_CODE);
//PLACE_AUTOCOMPLETE_REQUEST_CODE is integer for request code
    } catch (GooglePlayServicesRepairableException | GooglePlayServicesNotAvailableException e) {
        // TODO: Handle the error.
    }

}

@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
    super.onActivityResult(requestCode, resultCode, data);
    //autocompleteFragment.onActivityResult(requestCode, resultCode, data);
    if (requestCode == PLACE_AUTOCOMPLETE_REQUEST_CODE) {
        if (resultCode == RESULT_OK) {
            Place place = PlaceAutocomplete.getPlace(this, data);
            Log.i(TAG, "Place:" + place.toString());
        } else if (resultCode == PlaceAutocomplete.RESULT_ERROR) {
            Status status = PlaceAutocomplete.getStatus(this, data);
            Log.i(TAG, status.getStatusMessage());
        } else if (resultCode == RESULT_CANCELED) {

        }
    }
}

Output:

希望有帮助。

编辑：改变requestCode == RESULT_CANCELED to resultCode == RESULT_CANCELED
