searchInCity(PoiCitySearchOption option)
setOnGetPoiSearchResultListener（OnGetPoiSearchResultListener poiResultListener）
cityLimit(boolean cityLimit)
设置区域数据召回限制 为true时，仅召回city对应区域内数据
检索完成后需要调用PoiSearch的destroy()方法，否则会有内存泄露。
// 发起请求
mPoiSearch.searchInCity((new PoiCitySearchOption())
.city(cityStr)
.keyword(keyWordStr)
.pageNum(mLoadIndex) // 分页编号
.cityLimit(false)
.scope(scope));
