null)sugAdapter.add(info.key);}sugAdapter.notifyDataSetChanged();提醒数据发生改变这时 AutoCompleteTextView就会使用Adapter提供的字符串数据源然后给出 这几个步骤对应的 截图。-----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------最后给出官方BaiduMapsApiDemo 中的 POISearch.java 中的代码可以自己对照着比较package baidumapsdk.demo;import android.os.Bundle;import android.support.v4.app.FragmentActivity;import android.text.Editable;import android.text.TextWatcher;import android.view.View;import android.widget.ArrayAdapter;import android.widget.AutoCompleteTextView;import android.widget.EditText;import android.widget.Toast;import com.baidu.mapapi.map.BaiduMap;import com.baidu.mapapi.map.SupportMapFragment;import com.baidu.mapapi.overlayutil.PoiOverlay;import com.baidu.mapapi.search.core.CityInfo;import com.baidu.mapapi.search.core.PoiInfo;import com.baidu.mapapi.search.core.SearchResult;import com.baidu.mapapi.search.poi.OnGetPoiSearchResultListener;import com.baidu.mapapi.search.poi.PoiCitySearchOption;import com.baidu.mapapi.search.poi.PoiDetailResult;import com.baidu.mapapi.search.poi.PoiDetailSearchOption;import com.baidu.mapapi.search.poi.PoiResult;import com.baidu.mapapi.search.poi.PoiSearch;import com.baidu.mapapi.search.sug.OnGetSuggestionResultListener;import com.baidu.mapapi.search.sug.SuggestionResult;import com.baidu.mapapi.search.sug.SuggestionSearch;import com.baidu.mapapi.search.sug.SuggestionSearchOption;/*** 演示poi搜索功能*/public class PoiSearchDemo extends FragmentActivity implementsOnGetPoiSearchResultListener, OnGetSuggestionResultListener {private PoiSearch mPoiSearch null;private SuggestionSearch mSuggestionSearch null;private BaiduMap mBaiduMap null;/*** 搜索关键字输入窗口*/private AutoCompleteTextView keyWorldsView null;private ArrayAdapter sugAdapter null;private int load_Index 0;Overridepublic void onCreate(Bundle savedInstanceState) {super.onCreate(savedInstanceState);setContentView(R.layout.activity_poisearch);// 初始化搜索模块注册搜索事件监听mPoiSearch PoiSearch.newInstance();mPoiSearch.setOnGetPoiSearchResultListener(this);mSuggestionSearch SuggestionSearch.newInstance();mSuggestionSearch.setOnGetSuggestionResultListener(this);keyWorldsView (AutoCompleteTextView) findViewById(R.id.searchkey);sugAdapter new ArrayAdapter(this,android.R.layout.simple_dropdown_item_1line);keyWorldsView.setAdapter(sugAdapter);mBaiduMap ((SupportMapFragment) (getSupportFragmentManager().findFragmentById(R.id.map))).getBaiduMap();/*** 当输入关键字变化时动态更新建议列表*/keyWorldsView.addTextChangedListener(new TextWatcher() {Overridepublic void afterTextChanged(Editable arg0) {}Overridepublic void beforeTextChanged(CharSequence arg0, int arg1,int arg2, int arg3) {}Overridepublic void onTextChanged(CharSequence cs, int arg1, int arg2,int arg3) {if (cs.length() 0) {return;}String city ((EditText) findViewById(R.id.city)).getText().toString();/*** 使用建议搜索服务获取建议列表结果在onSuggestionResult()中更新*/mSuggestionSearch.requestSuggestion((new SuggestionSearchOption()).keyword(cs.toString()).city(city));}});}Overrideprotected void onPause() {super.onPause();}Overrideprotected void onResume() {super.onResume();}Overrideprotected void onDestroy() {mPoiSearch.destroy();mSuggestionSearch.destroy();super.onDestroy();}Overrideprotected void onSaveInstanceState(Bundle outState) {super.onSaveInstanceState(outState);}Overrideprotected void onRestoreInstanceState(Bundle savedInstanceState) {super.onRestoreInstanceState(savedInstanceState);}/*** 影响搜索按钮点击事件** param v*/public void searchButtonProcess(View v) {EditText editCity (EditText) findViewById(R.id.city);EditText editSearchKey (EditText) findViewById(R.id.searchkey);mPoiSearch.searchInCity((new PoiCitySearchOption()).city(editCity.getText().toString()).keyword(editSearchKey.getText().toString()).pageNum(load_Index));}public void goToNextPage(View v) {load_Index;searchButtonProcess(null);}public void onGetPoiResult(PoiResult result) {if (result null|| result.error SearchResult.ERRORNO.RESULT_NOT_FOUND) {Toast.makeText(PoiSearchDemo.this, 未找到结果, Toast.LENGTH_LONG).show();return;}if (result.error SearchResult.ERRORNO.NO_ERROR) {mBaiduMap.clear();PoiOverlay overlay new MyPoiOverlay(mBaiduMap);mBaiduMap.setOnMarkerClickListener(overlay);overlay.setData(result);overlay.addToMap();overlay.zoomToSpan();return;}if (result.error SearchResult.ERRORNO.AMBIGUOUS_KEYWORD) {// 当输入关键字在本市没有找到但在其他城市找到时返回包含该关键字信息的城市列表String strInfo 在;for (CityInfo cityInfo : result.getSuggestCityList()) {strInfo cityInfo.city;strInfo ,;}strInfo 找到结果;Toast.makeText(PoiSearchDemo.this, strInfo, Toast.LENGTH_LONG).show();}}public void onGetPoiDetailResult(PoiDetailResult result) {if (result.error !
