地点自动完成 Android

Places Autocomplete Android

我是 Android 开发新手。

我正在努力自动完成用户输入。我需要一个 google 地图,例如用户输入的自动完成。用户需要 select 地址、地点、街道 a.s.o。来自自动完成,我需要它的 LatLng。

我试图通过使用 google course 来完成此操作,但这并不是我想要的。我不想拥有整个片段或仅用于 select 某个地方的东西,我正在寻找 AutoCompleteTextView 解决方案。有没有简单易懂的方法来做到这一点?

我找到了 this,但这看起来不像 "normal way" 那样做,还是我错了?这是网络 API 电话而不是 Android API 电话,不是吗?

只是坚持 Google 的地方自动完成如果你想要它就像 AutoCompleteTextView.its MODE_OVERLAY 选项一样,只需执行以下操作。

Intent intent = new PlaceAutocomplete.IntentBuilder(PlaceAutocomplete.MODE_OVERLAY)
                    .build(mActivity);
            startActivityForResult(intent, REQUEST_CODE_AUTOCOMPLETE);

使用它来创建自定义地点建议并处理数据。下面是 Activity,它在 AutoCompleteTextView

中显示地点建议
public class MainActivity extends AppCompatActivity implements
        GoogleApiClient.OnConnectionFailedListener,
        GoogleApiClient.ConnectionCallbacks {
    private static final String LOG_TAG = "MainActivity";
    private static final int GOOGLE_API_CLIENT_ID = 0;
    private AutoCompleteTextView mAutocompleteTextView;
    private TextView mNameTextView;
    private TextView mAddressTextView;
    private TextView mIdTextView;
    private TextView mPhoneTextView;
    private TextView mWebTextView;
    private TextView mAttTextView;
    private GoogleApiClient mGoogleApiClient;
    private PlaceArrayAdapter mPlaceArrayAdapter;
    private static final LatLngBounds BOUNDS_MOUNTAIN_VIEW = new LatLngBounds(
            new LatLng(37.398160, -122.180831), new LatLng(37.430610, -121.972090));

    @Override

        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        mGoogleApiClient = new GoogleApiClient.Builder(MainActivity.this)
                .addApi(Places.GEO_DATA_API)
                .enableAutoManage(this, GOOGLE_API_CLIENT_ID, this)
                .addConnectionCallbacks(this)
                .build();
        mAutocompleteTextView = (AutoCompleteTextView) findViewById(R.id
                .autoCompleteTextView);
        mAutocompleteTextView.setThreshold(3);

        mAutocompleteTextView.setOnItemClickListener(mAutocompleteClickListener);
        mPlaceArrayAdapter = new PlaceArrayAdapter(this, android.R.layout.simple_list_item_1,
                BOUNDS_MOUNTAIN_VIEW, null);
        mAutocompleteTextView.setAdapter(mPlaceArrayAdapter);
    }

    private AdapterView.OnItemClickListener mAutocompleteClickListener
            = new AdapterView.OnItemClickListener() {
        @Override
        public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
            final PlaceArrayAdapter.PlaceAutocomplete item = mPlaceArrayAdapter.getItem(position);
            final String placeId = String.valueOf(item.placeId);
            Log.i(LOG_TAG, "Selected: " + item.description);
            PendingResult<PlaceBuffer> placeResult = Places.GeoDataApi
                    .getPlaceById(mGoogleApiClient, placeId);
            placeResult.setResultCallback(mUpdatePlaceDetailsCallback);
            Log.i(LOG_TAG, "Fetching details for ID: " + item.placeId);
        }
    };

    private ResultCallback<PlaceBuffer> mUpdatePlaceDetailsCallback
            = new ResultCallback<PlaceBuffer>() {
        @Override

                Log.e(LOG_TAG, "Place query did not complete. Error: " +
                        places.getStatus().toString());
                return;
            }
            // Selecting the first object buffer.
            final Place place = places.get(0);
            CharSequence attributions = places.getAttributions();

            mNameTextView.setText(Html.fromHtml(place.getName() + ""));
            mAddressTextView.setText(Html.fromHtml(place.getAddress() + ""));
            mIdTextView.setText(Html.fromHtml(place.getId() + ""));

            mWebTextView.setText(place.getWebsiteUri() + "");
            if (attributions != null) {

    };

    @Override

        Log.i(LOG_TAG, "Google Places API connected.");

    }

    @Override
    public void onConnectionFailed(ConnectionResult connectionResult) {
        Log.e(LOG_TAG, "Google Places API connection failed with error code: "
                + connectionResult.getErrorCode());

        Toast.makeText(this,
                "Google Places API connection failed with error code:" +
                        connectionResult.getErrorCode(),

    }

    @Override

        mPlaceArrayAdapter.setGoogleApiClient(null);
        Log.e(LOG_TAG, "Google Places API connection suspended.");
    }
}

所需过滤器适配器如下,可根据要求定制

public class PlaceArrayAdapter
        extends ArrayAdapter<PlaceArrayAdapter.PlaceAutocomplete> implements Filterable {
    private static final String TAG = "PlaceArrayAdapter";
    private GoogleApiClient mGoogleApiClient;
    private AutocompleteFilter mPlaceFilter;
    private LatLngBounds mBounds;
    private ArrayList<PlaceAutocomplete> mResultList;

    /**

     */

        mBounds = bounds;
        mPlaceFilter = filter;

    }

用于 Android 的 Google Play 服务版本的 Places SDK(在 Google Play 服务 16.0.0 中)已于 2019 年 1 月 29 日弃用,并将转为2019 年 7 月 29 日休息。

    Now how we use the **Sreehari** answers with new modifications?

如果有人知道解决方案,请告诉我 know.Currently 我使用了 android 自动完成 搜索 process.But 仍在努力将旧的自动完成地点搜索迁移到新的。
