官方文档 http://lbsyun.baidu.com/index.php?title=androidsdk/guide/key

先去官方文档申请秘钥下载压缩文件等操作,参考

公交,步行,驾车路线查询,附近POI查询

参考文档导入所需jar包和so文件

标注点,覆盖物的实现见官方文档

poi检索:

1.首先获取地图,创建poi检索实例:

private voidinitView() {//输入框

etPoi =(EditText) inflate.findViewById(R.id.fragment_detailpage_search_et_poi);//检索图标

ivSearch =(ImageView) inflate.findViewById(R.id.fragment_detailpage_search_iv_search);//设置点击监听

ivSearch.setOnClickListener(this);//获取地图控件引用

mMapView =(MapView)inflate.findViewById(R.id.bmapView);

mBaiduMap=mMapView.getMap();//普通地图

mBaiduMap.setMapType(BaiduMap.MAP_TYPE_NORMAL);//创建POI检索实例

mPoiSearch =PoiSearch.newInstance();

//详细信息布局

mMarkerInfoLayout=(RelativeLayout)inflate. findViewById(R.id.layout_map_rl_layout);

}

2.为poi检索设置监听,监听回调了两个方法,第一个是poi检索结果的监听,当用户进行poi检索后,会回调该方法,第二个方法,是对检索后显示的标注点(marker)进行点击后回调的方法,会传入该点的详情结果对象,我们可以通过该对象得到名字,地址,url地址等

//设置监听

mPoiSearch.setOnGetPoiSearchResultListener(newOnGetPoiSearchResultListener() {/*1.获得poi检索结果的监听*/@Overridepublic voidonGetPoiResult(PoiResult poiResult) {

//创建覆盖物对象

myPoiOverlay= newMyPoiOverlay(mBaiduMap);

myPoiOverlay.setData(poiResult);

myPoiOverlay.addToMap();

myPoiOverlay.zoomToSpan();//给poi的结果设置点击事件,点击marker后弹出详情页

mBaiduMap.setOnMarkerClickListener(myPoiOverlay);

Log.i("tag", "获得poi检索结果的监听 ");

}/*3. poi的详情页结果*/@Overridepublic voidonGetPoiDetailResult(PoiDetailResult poiDetailResult) {if (poiDetailResult.error !=SearchResult.ERRORNO.NO_ERROR) {

Toast.makeText(getActivity(),"抱歉，未找到结果",

Toast.LENGTH_SHORT).show();

etPoi.setText("");

}else {//正常返回结果的时候，此处可以获得很多相关信息//获取详情页的请求结果

String detailUrl =poiDetailResult.getDetailUrl();//得到当前经纬度

Log.i("tag", "获取详情页的请求结果: detailUrl -" + poiDetailResult.getName() + ": "

+poiDetailResult.getAddress());

Toast.makeText(getActivity(), detailUrl, Toast.LENGTH_SHORT).show();//弹出窗体//设置详细信息布局为可见

mMarkerInfoLayout.setVisibility(View.VISIBLE);//根据商家信息为详细信息布局设置信息

popupInfo(mMarkerInfoLayout, poiDetailResult);

}}

@Overridepublic voidonGetPoiIndoorResult(PoiIndoorResult poiIndoorResult) {

}

});

上面创建的MyPoiOverlay是继承了PoiOverLay的,需要重写onPoiClick,当poi检索的结果被点击的时候回调该方法,然后通过获得该标注点的uid得到详情结果然后将详情结果,传入检索监听中的onGetPoiDetailResult(PoiDetailResult poiDetailResult),

注意:需要为marker设置点击监听,

mBaiduMap.setOnMarkerClickListener(myPoiOverlay);

class MyPoiOverlay extendsPoiOverlay {/*** 构造函数

*

*@parambaiduMap 该 PoiOverlay 引用的 BaiduMap 对象*/

publicMyPoiOverlay(BaiduMap baiduMap) {super(baiduMap);

}/*2.当poi的结果点被点击的时候调用*/@Overridepublic boolean onPoiClick(inti) {//获取i对应的点的uid

String uid =getPoiResult().getAllPoi().get(i).uid;

Log.i("tag", "当poi的结果点被点击的时候调用: "+uid);//uid是POI检索中获取的POI ID信息

mPoiSearch.searchPoiDetail((newPoiDetailSearchOption()).poiUid(uid));return super.onPoiClick(i);

}

}

popInfo:使用viewHolder复用布局

private void popupInfo(RelativeLayout mMarkerInfoLayout,finalPoiDetailResult poiDetailResult) {

ViewHolder viewHolder= null;if(mMarkerInfoLayout.getTag() == null){

viewHolder= newViewHolder();

viewHolder.poiName=(TextView) inflate.findViewById(R.id.layout_map_poiname);

viewHolder.poiAddress=(TextView)inflate.findViewById(R.id.layout_map_poiaddress);

viewHolder.poiSearch=(TextView) inflate.findViewById(R.id.layout_map_button);

mMarkerInfoLayout.setTag(viewHolder);

}else{

viewHolder=(ViewHolder) mMarkerInfoLayout.getTag();

viewHolder.poiName.setText(poiDetailResult.getName());

viewHolder.poiAddress.setText(poiDetailResult.getAddress());

viewHolder.poiSearch.setOnClickListener(newView.OnClickListener() {

@Overridepublic voidonClick(View v) {//弹出新的页面展示poi详情

Intent intent = new Intent(getActivity(), PoiDetailActivity.class);

intent.putExtra("POI_DETAIL_URL",poiDetailResult.getDetailUrl());

startActivity(intent);

}

});

}

}classViewHolder{

TextView poiName;

TextView poiSearch;

TextView poiAddress;

}

为地图设置点击事件,点击隐藏布局

mBaiduMap.setOnMapClickListener(newBaiduMap.OnMapClickListener()

{

@Overridepublic booleanonMapPoiClick(MapPoi arg0)

{return false;

}

@Overridepublic voidonMapClick(LatLng arg0)

{

mMarkerInfoLayout.setVisibility(View.GONE);

mBaiduMap.hideInfoWindow();

}

});

开始搜索poi:按城市内搜索

public voidonStartSearch(View view){//String keyword = etKeyword.getText().toString().trim();

/*if (TextUtils.isEmpty(keyword)){

return;

}*/Log.i("tag", "onStartSearch: ");

mPoiSearch.searchInCity(new PoiCitySearchOption().city("杭州").keyword("美食").pageNum(10));/*** 附近检索*/

/*PoiNearbySearchOption nearbySearchOption = new PoiNearbySearchOption();

nearbySearchOption.location(new LatLng(latitude, longitude));

nearbySearchOption.keyword(editSearchKeyEt.getText().toString());

nearbySearchOption.radius(1000);// 检索半径，单位是米

nearbySearchOption.pageNum(10);

mPoiSearch.searchNearby(nearbySearchOption);// 发起附近检索请求*/}

DetailPoiActivity

public class PoiDetailActivity extendsActivity {privateWebView wbPoiDetail;

@Overrideprotected voidonCreate(Bundle savedInstanceState) {super.onCreate(savedInstanceState);

setContentView(R.layout.activity_poidetail);

wbPoiDetail=(WebView) findViewById(R.id.wv_poidetail);

Intent intent=getIntent();

String url= intent.getStringExtra("POI_DETAIL_URL");

Log.i("MainActivity", "url-" +url);//webview加载数据

wbPoiDetail.loadUrl(url);

wbPoiDetail.setWebViewClient(new WebViewClient(){//解决办法

public booleanshouldOverrideUrlLoading(WebView view, String url) {//返回true的时候网页在webView中去打开，如果为false则是调用系统浏览器打开

view.loadUrl(url);return true;

}

});

}

}

效果如下:

线路规划基本步骤:

分析:

1.创建路规划检索实例

设置点击事件

2.准备检索起、终点信息

3.发起线路规划的检索

1.公交检索

2.驾车检索

3.步行

4.设置检索结果监听器

5.实现监听器

根据不同的结果展示不同的路线

1.公交检索

2.驾车检索

3.步行
