1.DistrictSearch

DistrictSearch是行政区域检索接口，通过DistrictSearchOption参数类获取区域；可以通过此类来绘制区域的图层显示；

2. 相关类

2.1 DistrictSearch(行政检索)

DistrictSearch是行政区域检索接口，包括了newInstance(行政区域构造)、searchDistrict(行政区域搜索)、setOnDistrictSearchListener(设置检索监听)、destroy(释放资源)函数；

2.2 DistrictSearchOption(行政检索参数)

通过city(cityName)和districtName(districtName)设置城市和区域参数;

2.3 DistrictResult(检索结果)

行政区域检索返回结果；

2.4 onGetDistrictResult(行政检索监听)

重写onGetDistrictResult()回调函数，获取检索的结果；

void onGetDistrictResult(DistrictResult result)行政区域检索结果回调
参数:

3 行政区域案例

1. 创建DistrictSearch对象

districtSearch = DistrictSearch.newInstance();

2. 添加监听

districtSearch.setOnDistrictSearchListener(new MyDistricSearchListener());

3. 创建行政检索参数DistrictSearchOption对象

DistrictSearchOption option = new DistrictSearchOption();
option.cityName(etxt_city.getText().toString());
option.districtName(etxt_district.getText().toString());
districtSearch.searchDistrict(option);

4. 开始搜索

districtSearch.searchDistrict(option);

5. 自定义检索监听

private class MyDistricSearchListener implements OnGetDistricSearchResultListener {@Overridepublic void onGetDistrictResult(DistrictResult districtResult) {if (districtResult == null || districtResult.error != SearchResult.ERRORNO.NO_ERROR) {showToast("未找到结果");}if (districtResult.error == SearchResult.ERRORNO.NO_ERROR) {List<List<LatLng>> polyLines = districtResult.getPolylines();if (polyLines == null) {return;}LatLngBounds.Builder builder = new LatLngBounds.Builder();for (List<LatLng> LatLngList : polyLines) {//绘制区域边界OverlayOptions polylineOption = new PolylineOptions().width(10).points(LatLngList).dottedLine(true).color(0xAA00FF00);baiduMap.addOverlay(polylineOption);//绘制区域填充OverlayOptions polygonOption = new PolygonOptions().points(LatLngList)..fillColor(0xAAFFFF00)stroke(new Stroke(5, 0xAA00FF88));baiduMap.addOverlay(polygonOption);//设置地图的显示范围for (LatLng latLng : LatLngList) {builder.include(latLng);}baiduMap.setMapStatus(MapStatusUpdateFactory.newLatLngBounds(builder.build()));}}}
}

6. 销毁对象

districtSearch.destroy();
