Android BaiduMapSug检索 即关键字匹配
注意：Sug检索，city为必填项。
Sug检索默认不限制在city内，检索结果优先展示city内结果。
地点检索输入提示检索（Sug检索）
地点检索输入提示服务（也被称为POI热词建议检索、在线建议检索、Suggestion POI search）,简称Sug检索，是指根据关键词查询在线建议词。为了帮助开发者实现检索出来的关键词快速定位到地图上，SDK开放了检索结果的经纬度信息及对应POI点的UID信息。
Sug检索示例
布局：
<?xml version="1.0" encoding="utf-8"?><LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="fill_parent" android:layout_height="fill_parent" android:orientation="vertical"> <LinearLayout android:layout_width="fill_parent" android:layout_height="50dip" android:background="@color/dkgray" android:orientation="horizontal"> <TextView android:layout_width="wrap_content" android:layout_height="wrap_content" android:text="在" android:textColor="@color/white" android:textStyle="bold" /> <EditText android:id="@+id/city" android:layout_width="wrap_content" android:layout_height="match_parent" android:text="北京" android:textColor="@color/white" /> <TextView android:layout_width="wrap_content" android:layout_height="wrap_content" android:text="市内找" android:textColor="@color/white" android:textStyle="bold" /> <AutoCompleteTextView android:id="@+id/searchkey" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_weight="0.88" android:hint="请输入联想关键字" android:textColor="@color/white" /> </LinearLayout> <ListView android:id="@+id/sug_list" android:layout_width="match_parent" android:layout_height="wrap_content" /></LinearLayout>
1.
// 初始化建议搜索模块，注册建议搜索事件监听
mSuggestionSearch = SuggestionSearch.newInstance();
mSuggestionSearch.setOnGetSuggestionResultListener(this);
2.
/**
* 获取在线建议搜索结果，得到requestSuggestion返回的搜索结果
*
* @param suggestionResult Sug检索结果
*/
@Override
public void onGetSuggestionResult(SuggestionResult suggestionResult) {
if (suggestionResult ==null || suggestionResult.getAllSuggestions() ==null) {
return;
}
List> suggest =new ArrayList<>();
for (SuggestionResult.SuggestionInfo info : suggestionResult.getAllSuggestions()) {
if (info.getKey() !=null && info.getDistrict() !=null && info.getCity() !=null) {
HashMap map =new HashMap<>();
map.put("key",info.getKey());
map.put("city",info.getCity());
map.put("dis",info.getDistrict());
suggest.add(map);
}
}
SimpleAdapter simpleAdapter =new SimpleAdapter(getApplicationContext(),
suggest,
R.layout.item_layout,
new String[]{"key", "city","dis"},
new int[]{R.id.sug_key, R.id.sug_city, R.id.sug_dis});
mSugListView.setAdapter(simpleAdapter);
simpleAdapter.notifyDataSetChanged();
}
3.
// 当输入关键字变化时，动态更新建议列表
mKeyWordsView.addTextChangedListener(new TextWatcher() {
@Override
public void afterTextChanged(Editable arg0) {
}
@Override
public void beforeTextChanged(CharSequence arg0, int arg1, int arg2, int arg3) {
}
@Override
public void onTextChanged(CharSequence cs, int arg1, int arg2, int arg3) {
if (cs.length() <=0) {
return;
}
// 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())// 关键字
.city(mEditCity.getText().toString())); // 城市
}
});
4.释放检索实例
@Override
protected void onDestroy() {
super.onDestroy();
mSuggestionSearch.destroy();
}
