学习一门新的技术，最好参考官方的文档。

这是百度地图官方参考资料：http://lbsyun.baidu.com/index.php?title=androidsdk/guide/hellobaidumap

一、实现普通地图、卫星地图、实时交通

大体实现步骤： 1、将百度地图引入到我们的app中去 2、通过菜单选项实现普通地图、卫星地图、实时交通的开关源码实现： /baidudemo/res/layout/activity_main.xml

<RelativeLayout 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"
    tools:context=".MainActivity" >

  <com.baidu.mapapi.map.MapView  
    android:id="@+id/bmapView"  
    android:layout_width="fill_parent"  
    android:layout_height="fill_parent"  
    android:clickable="true" />

</RelativeLayout>

/baidudemo/res/menu/main.xml

<menu xmlns:android="http://schemas.android.com/apk/res/android" >

    <item
        android:id="@+id/id_map_common"
        android:showAsAction="never"
        android:title="普通地图"/>
    <item
        android:id="@+id/id_map_site"
        android:showAsAction="never"
        android:title="卫星地图"/>
    <item
        android:id="@+id/id_map_traffic"
        android:showAsAction="never"
        android:title="实时交通(off)"/>

</menu>

public class MainActivity extends Activity {

private MapView mMapView;
private BaiduMap mBaiduMap;

@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
requestWindowFeature(Window.FEATURE_NO_TITLE);
// 在使用SDK各组件之前初始化context信息，传入ApplicationContext

MapStatusUpdate msu = MapStatusUpdateFactory.zoomTo(15.0f);
mBaiduMap.setMapStatus(msu);
}

@Override

mMapView.onDestroy();
}

@Override
public boolean onCreateOptionsMenu(Menu menu) {
getMenuInflater().inflate(R.menu.main, menu);
return true;
}

@Override
public boolean onOptionsItemSelected(MenuItem item) {
switch (item.getItemId()) {
case R.id.id_map_common:
mBaiduMap.setMapType(BaiduMap.MAP_TYPE_NORMAL);
break;
case R.id.id_map_site:
mBaiduMap.setMapType(BaiduMap.MAP_TYPE_SATELLITE);
break;
case R.id.id_map_traffic:
if(mBaiduMap.isTrafficEnabled()){//为true，可以进行实时交通。
//菜单项再点击一次就不能进行实时交通，并修改显示信息
mBaiduMap.setTrafficEnabled(false);
item.setTitle("实时交通(off)");
}else{
mBaiduMap.setTrafficEnabled(true);
item.setTitle("实时交通(on)");
}
break;

default:
break;
}
return super.onOptionsItemSelected(item);
}
}

运行效果：

二、定位功能，定位我的位置

实现所需的类： LocationClient、LocationClientOption进行定位的一些设置、BDLocationListener、BDLocation、MyLocationData。代码实现： /baidudemo/res/menu/main.xml

    <item
        android:id="@+id/id_map_common"
        android:showAsAction="never"
        android:title="普通地图"/>
    <item
        android:id="@+id/id_map_site"
        android:showAsAction="never"
        android:title="卫星地图"/>
    <item
        android:id="@+id/id_map_traffic"
        android:showAsAction="never"
        android:title="实时交通(off)"/>
    <item
