Android百度地图实现搜索地址

1.获取当前定位

 // 獲取當前位置
 baiduMap.setMyLocationEnabled(true);

 locationClient = new LocationClient(this);
 initLocation();

 MyLocationListener myLocationListener = new MyLocationListener();
 locationClient.registerLocationListener(myLocationListener);
 locationClient.start();

 private void initLocation() {
        LocationClientOption option = new LocationClientOption();
        option.setLocationMode(LocationClientOption.LocationMode.Device_Sensors);
        option.setOpenGps(true);
        option.setCoorType(CoordType.BD09LL.name());
        option.setScanSpan(1000);
        option.setIsNeedAddress(true);
        option.setIsNeedLocationDescribe(true);
        option.setIsNeedLocationPoiList(true);
        option.setLocationNotify(true);
        option.setIgnoreKillProcess(false);
        option.SetIgnoreCacheException(false);
        option.setEnableSimulateGps(false);
        option.setWifiCacheTimeOut(5 * 60 * 1000);

        locationClient.setLocOption(option);
    }

  /**
     * 獲取定位數據
     */
    class MyLocationListener extends BDAbstractLocationListener {

        @Override
        public void onReceiveLocation(BDLocation bdLocation) {
            // mapView銷毀后不再處理新接收的位置
            if (bdLocation == null || mapView == null) {
                return;
            }

            nowLatLng = new LatLng(bdLocation.getLatitude(), bdLocation.getLongitude());
            if (isFirst) {
                isFirst = false;
                baiduMap.animateMapStatus(MapStatusUpdateFactory.newLatLng(nowLatLng));
                lat = bdLocation.getLatitude();
                lng = bdLocation.getLongitude();
                province = bdLocation.getProvince();
                city = bdLocation.getCity();
                district = bdLocation.getDistrict();
                address = bdLocation.getAddress().town + bdLocation.getStreet() + bdLocation.getAddress().streetNumber;
            }
            // 在地图上显示当前定位
            MyLocationData locData = new MyLocationData.Builder()
                    .accuracy(bdLocation.getRadius())
                    .direction(bdLocation.getDirection())
                    .latitude(bdLocation.getLatitude())
                    .longitude(bdLocation.getLongitude())
                    .build();
            baiduMap.setMyLocationData(locData);
        }
    }

2. 实现SuggestionSearch

 mSuggestionSearch = SuggestionSearch.newInstance();

3. 监听EditText的TextChanged事件

 mSuggestionSearch.requestSuggestion(new SuggestionSearchOption()
                        .keyword(s.toString()) // s是onTextChanged里面的字段
                        .city(city) // 这里的city是获取当前定位的city，若不限制城市搜索可以不设置
                        .citylimit(false) // 不限制城市
                );

4. 设置SuggestionSearch获取结果监听事件

mSuggestionSearch.setOnGetSuggestionResultListener(new OnGetSuggestionResultListener());

 class OnGetSuggestionResultListener implements com.baidu.mapapi.search.sug.OnGetSuggestionResultListener{

        @Override
        public void onGetSuggestionResult(SuggestionResult suggestionResult) {
        // 这里显示是用RecyclerView显示数据
            if (suggestionResult != null && suggestionResult.getAllSuggestions() != null) {
                list.clear();
                for (SuggestionResult.SuggestionInfo info : suggestionResult.getAllSuggestions()) {
                    list.add(new LocationBean(info));
                }
                adapter.notifyDataSetChanged();
            }
        }
    }
