三、公布代码，并在android项目中引用百度SDK

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="example.com.baidu_map">

</manifest>

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical"
    tools:context="example.com.baidu_map.MainActivity">

    <com.baidu.mapapi.map.MapView

        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:clickable="true" />

</LinearLayout>

package example.com.baidu_map;

import com.baidu.mapapi.SDKInitializer;
import com.baidu.mapapi.map.BaiduMap;
import com.baidu.mapapi.map.MapView;
import android.app.Activity;
import android.os.Bundle;
import android.view.View;
import android.view.Window;

public class MainActivity extends Activity {
        // 百度地图控件
        private MapView mMapView = null;
        // 百度地图对象
        private BaiduMap bdMap;
        @Override
        protected void onCreate(Bundle savedInstanceState) {
            super.onCreate(savedInstanceState);
            requestWindowFeature(Window.FEATURE_NO_TITLE);

            SDKInitializer.initialize(getApplicationContext());
            setContentView(R.layout.activity_main);
            init();
        }

        /**
         * 初始化方法
         */
        private void init() {
            mMapView = (MapView) findViewById(R.id.bmapview);
            bdMap = mMapView.getMap();
//普通地图
            bdMap.setMapType(BaiduMap.MAP_TYPE_NORMAL);
        }
        @Override
        protected void onResume() {
            super.onResume();
            mMapView.onResume();
        }
        @Override
        protected void onPause() {
            super.onPause();
            mMapView.onPause();
        }
        @Override
        protected void onDestroy() {
            mMapView.onDestroy();
            mMapView = null;
            super.onDestroy();
        }
    }

四、显示实时交通图（路况图）

百度地图将地图的类型分为两种：普通矢量地图和卫星图。

这里将mBaiduMap改为：bdMap

1. mMapView = (MapView) findViewById(R.id.bmapView);   
2. mBaiduMap = mMapView.getMap();     
3. //普通地图    
4. mBaiduMap.setMapType(BaiduMap.MAP_TYPE_NORMAL);    
5. //卫星地图    
6. mBaiduMap.setMapType(BaiduMap.MAP_TYPE_SATELLITE);  

1. //开启交通图     
2. mBaiduMap.setTrafficEnabled(true);  

1. //开启热力图     
2. mBaiduMap.setBaiduHeatMapEnabled(true);
