參考文檔導入所需jar包和so文件

 poi檢索:
1.首先獲取地圖,創建poi檢索實例:

   private void initView() {
        //輸入框
        etPoi = (EditText) inflate.findViewById(R.id.fragment_detailpage_search_et_poi);
        //檢索圖標
        ivSearch = (ImageView) inflate.findViewById(R.id.fragment_detailpage_search_iv_search);
        //設置點擊監聽
        ivSearch.setOnClickListener(this);
        //獲取地圖控件引用
        mMapView = (MapView)inflate.findViewById(R.id.bmapView);
        mBaiduMap = mMapView.getMap();
        //普通地圖
        mBaiduMap.setMapType(BaiduMap.MAP_TYPE_NORMAL);
        //創建POI檢索實例
        mPoiSearch = PoiSearch.newInstance();
　　　　　//詳細信息布局
        mMarkerInfoLayout = (RelativeLayout)inflate. findViewById(R.id.layout_map_rl_layout);

    }

 

 2.為poi檢索設置監聽,監聽回調了兩個方法,第一個是poi檢索結果的監聽,當用戶進行poi檢索后,會回調該方法,第二個方法,是對檢索后顯示的標注點(marker)進行點擊后回調的方法,會傳入該點的詳情結果對象,我們可以通過該對象得到名字,地址,url地址等

      //設置監聽
        mPoiSearch.setOnGetPoiSearchResultListener(new OnGetPoiSearchResultListener() {

        /*    1.獲得poi檢索結果的監聽*/

            @Override
            public void onGetPoiResult(PoiResult poiResult) {
　　　　　　　　　//創建覆蓋物對象
                myPoiOverlay = new MyPoiOverlay(mBaiduMap);
                myPoiOverlay.setData(poiResult);
                myPoiOverlay.addToMap();
                myPoiOverlay.zoomToSpan();
                //給poi的結果設置點擊事件,點擊marker后彈出詳情頁
                mBaiduMap.setOnMarkerClickListener(myPoiOverlay);
                Log.i("tag", "獲得poi檢索結果的監聽 ");
            }
            /* 3. poi的詳情頁結果*/
            @Override
            public void onGetPoiDetailResult(PoiDetailResult poiDetailResult) {
                if (poiDetailResult.error != SearchResult.ERRORNO.NO_ERROR) {
                    Toast.makeText(getActivity(), "抱歉，未找到結果",
                            Toast.LENGTH_SHORT).show();
                    etPoi.setText("");
                } else {// 正常返回結果的時候，此處可以獲得很多相關信息
                    //獲取詳情頁的請求結果
                    String detailUrl = poiDetailResult.getDetailUrl();
                    //得到當前經緯度
                    Log.i("tag", "獲取詳情頁的請求結果: detailUrl -" +  poiDetailResult.getName() + ": "
                            + poiDetailResult.getAddress());
                    Toast.makeText(getActivity(), detailUrl, Toast.LENGTH_SHORT).show();
                    //彈出窗體
                    // 設置詳細信息布局為可見
                    mMarkerInfoLayout.setVisibility(View.VISIBLE);
                    //根據商家信息為詳細信息布局設置信息
                    popupInfo(mMarkerInfoLayout, poiDetailResult);
                }}

            @Override
            public void onGetPoiIndoorResult(PoiIndoorResult poiIndoorResult) {

            }
        });

上面創建的MyPoiOverlay是繼承了PoiOverLay的,需要重寫onPoiClick,當poi檢索的結果被點擊的時候回調該方法,然后通過獲得該標注點的uid得到詳情結果然后將詳情結果,傳入檢索監聽中的onGetPoiDetailResult(PoiDetailResult poiDetailResult),

注意:需要為marker設置點擊監聽,

 mBaiduMap.setOnMarkerClickListener(myPoiOverlay);

   class MyPoiOverlay extends PoiOverlay {

        /**
         * 構造函數
         *
         * @param baiduMap 該 PoiOverlay 引用的 BaiduMap 對象
         */
        public MyPoiOverlay(BaiduMap baiduMap) {
            super(baiduMap);
        }

        /*2.當poi的結果點被點擊的時候調用*/
        @Override
        public boolean onPoiClick(int i) {

            //獲取i對應的點的uid
            String uid = getPoiResult().getAllPoi().get(i).uid;
            Log.i("tag", "當poi的結果點被點擊的時候調用: "+uid);
            //uid是POI檢索中獲取的POI ID信息
            mPoiSearch.searchPoiDetail((new PoiDetailSearchOption()).poiUid(uid));
            return super.onPoiClick(i);
        }
    }

popInfo:使用viewHolder復用布局

 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) {
                       //彈出新的頁面展示poi詳情
                Intent intent = new Intent(getActivity(), PoiDetailActivity.class);
                intent.putExtra("POI_DETAIL_URL",poiDetailResult.getDetailUrl());
                startActivity(intent);
                }
            });
        }
    }
    class ViewHolder{
        TextView poiName;
        TextView poiSearch;
        TextView poiAddress;

    }

為地圖設置點擊事件,點擊隱藏布局

        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();
            }
        });

 開始搜索poi:按城市內搜索

    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));
        /**
         * 附近檢索
         */
/*
        PoiNearbySearchOption nearbySearchOption = new PoiNearbySearchOption();
        nearbySearchOption.location(new LatLng(latitude, longitude));
        nearbySearchOption.keyword(editSearchKeyEt.getText().toString());
        nearbySearchOption.radius(1000);// 檢索半徑，單位是米
        nearbySearchOption.pageNum(10);
        mPoiSearch.searchNearby(nearbySearchOption);// 發起附近檢索請求*/

    }

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加載數據
        wbPoiDetail.loadUrl(url);

        wbPoiDetail.setWebViewClient(new WebViewClient(){//解決辦法
                         public boolean shouldOverrideUrlLoading(WebView view, String url) {
                                //返回true的時候網頁在webView中去打開，如果為false則是調用系統瀏覽器打開
                               view.loadUrl(url);
                                return true;
                            }
        });

    }
}

 

效果如下:

線路規划基本步驟:

分析:
    1.創建路規划檢索實例
      設置點擊事件
    2.准備檢索起、終點信息
    3.發起線路規划的檢索
      1.公交檢索
      2.駕車檢索
      3.步行
      4.設置檢索結果監聽器
      5.實現監聽器
    根據不同的結果展示不同的路線
      1.公交檢索
      2.駕車檢索
      3.步行
