(轉載請注明出處哦)具體的百度地圖權限和apikey配置以及基礎地圖的配置不敘述，百度地圖定位可以看這個鏈接的http://blog.csdn.net/heweigzf/article/details/51084358，先來看一波搜索需要的基本布局layout

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15

<AutoCompleteTextView ????????????android:id="@+id/autosearchresult" ????????????android:background="@null" ????????????android:hint="@string/please_input_addr" ????????????android:layout_width="match_parent" ????????　　　　 android:layout_height="@dimen/y30" ????????????android:completionThreshold="2" ????????android:background="@drawable/edittext_shap" ????????????android:singleLine="true"/> <ListView ????????android:id="@+id/poimsglist" ????????android:divider="@color/grey" ????????android:dividerHeight="1px" ????????android:layout_width="match_parent" ????????android:layout_height="match_parent"/>

AutoCompleteTextView可以換成EditTextView，都是可以的，既然是城市poi檢索，就會有需要的城市名，可以是定位得到的也可以是傳值過來的，這里我就以Intent傳值的形式了，先初始化城市檢索核心類

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21

/** ?????* 城市內搜索 ?????*/? ????private?void?citySearch(int?page,String keyword,int?pageCapacity) {? ????????Intent intent=getIntent(); ????????if(intent!=null){ ????????????String city=intent.getStringExtra("city"); ????????????if(city!=null){ ???????????????mPoiSearch=PoiSearch.newInstance(); ???????????????mPoiSearch.setOnGetPoiSearchResultListener(this);?// 監聽檢索結果回調 ????????????????// 設置檢索參數? ????????????????PoiCitySearchOption citySearchOption =?new?PoiCitySearchOption();? ????????????????citySearchOption.city(city);// 城市? ????????????????citySearchOption.keyword(keyword);// 關鍵字? ????????????????citySearchOption.pageCapacity(pageCapacity);// 默認每頁10條? ????????????????citySearchOption.pageNum(page);// 分頁編號? ????????????????// 發起檢索請求? ????????????????mPoiSearch.searchInCity(citySearchOption); ????????????} ????????} }

接下來就是運用以上的方法了，可以明顯的看出來我們是通過輸入框來自動檢索，需要的給AutoCompleteTextView設置輸入監聽

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19

autosearchresult.addTextChangedListener(this); @Override ????public?void?beforeTextChanged(CharSequence s,?int?start,?int?count, ????????????int?after) { ????} ????@Override ????public?void?onTextChanged(CharSequence s,?int?start,?int?before,?int?count) { ????} ????// 輸入完成后自動進行檢索調用以上citySearch方法 ????@Override ????public?void?afterTextChanged(Editable s) { ????????String searchdialog=s.toString(); ????????if(searchdialog.length()>1){ ????????????citySearch(0, searchdialog,?20); ????????} ????}?

檢索成功后，以下為OnGetPoiSearchResultListener回調的檢索結果，getAllPoi()包含所有的檢索結果

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37

private?ArrayList<String> addrs=new?ArrayList<String>(); private?ArrayList<String> names=new?ArrayList<String>(); private?ArrayList<LatLng> mlLatLngs=new?ArrayList<LatLng>(); @Override ????public?void?onGetPoiDetailResult(PoiDetailResult arg0) { ????????//獲取Place詳情頁檢索結果 ????} ????@Override ????public?void?onGetPoiResult(PoiResult arg0) { ????????//獲取POI檢索結果 ????????if(arg0.error!=SearchResult.ERRORNO.NO_ERROR){ ????????????//BaseApp.getInstance().showToast("檢索fail"); ????????}else?{ ????????????if(addrs!=null){ ????????????????addrs.clear(); ????????????} ????????????if(mlLatLngs!=null){ ????????????????mlLatLngs.clear(); ????????????} ????????????if(names!=null){ ????????????????names.clear(); ????????????} ????????????if(arg0.getAllPoi()!=null&&arg0.getAllPoi().size()>0){ ????????????????List<PoiInfo> mPoiInfos=arg0.getAllPoi(); ????????????????for?(int?i =?0; i < mPoiInfos.size(); i++) { ????????????????????names.add(mPoiInfos.get(i).name); ????????????????????addrs.add(mPoiInfos.get(i).address); ????????????????????mlLatLngs.add(mPoiInfos.get(i).location); ????????????????//對需要的信息設置適配器，如果想在其他界面用，可以自己創建回調接口 mSearchListAdapter=new?SearchListAdapter(addrs, names, BaseApp.getInstance()); ????????????????????poiresultlist.setAdapter(mSearchListAdapter); ????????????????} ????????????} ????????} ????}

最后很重要的一步，要記得銷毀poisearch對象，避免可能會報空指針異常

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15

@Override ????public?void?onBackPressed() { ????????super.onBackPressed(); ????????if(mPoiSearch!=null){ ????????????mPoiSearch.destroy(); ????????} ????} ????? ????@Override ????public?void?onDestroy() { ????????super.onDestroy(); ????????if(mPoiSearch!=null){ ????????????mPoiSearch.destroy(); ????????} ????}
