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 void initView() {
//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(new OnGetPoiSearchResultListener() { /* 1.获得poi检索结果的监听*/ @Override
public void onGetPoiResult(PoiResult poiResult) {
//创建覆盖物对象
myPoiOverlay = new MyPoiOverlay(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*/
@Override
public void onGetPoiDetailResult(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);
}} @Override
public void onGetPoiIndoorResult(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 extends PoiOverlay {
/**
* 构造函数
*
* @param baiduMap 该 PoiOverlay 引用的 BaiduMap 对象
*/
public MyPoiOverlay(BaiduMap baiduMap) {
super(baiduMap);
}
/*2.当poi的结果点被点击的时候调用*/
@Override
public boolean onPoiClick(int i) {
//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((new PoiDetailSearchOption()).poiUid(uid));
return super.onPoiClick(i);
}
}
popInfo:使用viewHolder复用布局
private void popupInfo(RelativeLayout mMarkerInfoLayout,final PoiDetailResult poiDetailResult) {
ViewHolder viewHolder = null;
if(mMarkerInfoLayout.getTag() == null){
viewHolder = new ViewHolder();
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(new View.OnClickListener() {
@Override
public void onClick(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);
}
});
}
}
class ViewHolder{
TextView poiName;
TextView poiSearch;
TextView poiAddress;
}
为地图设置点击事件,点击隐藏布局
mBaiduMap.setOnMapClickListener(new BaiduMap.OnMapClickListener()
{
@Override
public boolean onMapPoiClick(MapPoi arg0)
{
return false;
} @Override
public void onMapClick(LatLng arg0)
{
mMarkerInfoLayout.setVisibility(View.GONE);
mBaiduMap.hideInfoWindow();
}
});
开始搜索poi:按城市内搜索
public void onStartSearch(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 extends Activity {
private WebView wbPoiDetail;
@Override
protected void onCreate(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 boolean shouldOverrideUrlLoading(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
