历经几天时间，终于把定位功能给实现了，可谓是费劲千辛万苦啊，有定位知识还有图层知识，在这里我把代码给大家贴出来，一起分享一下下啦。

//更新定位数据

//更新图层数据执行刷新后生效

//是手动触发请求或首次定位时，移动到定位点 mMapController.animateTo(new GeoPoint((int)(locData.latitude* 1e6), (int)(locData.longitude * 1e6)));

需要用到的jar包大家可以到百度地图api网站上下载。主要依赖于下列包：
manifest.xml配置如下：
<?xml version="1.0" encoding="utf-8"?>

界面只有一个mapview地图控件，在此列出activity_main.xml：
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:orientation="vertical"
> <com.baidu.mapapi.map.MapView android:id="@+id/bmapsView"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:clickable="true" />
> </LinearLayout>
