android百度定位

吐槽一下，百度地图用的真心的不怎么滴，但是需求这样，只能硬着头写了，首先加载权限：

<application
android:allowBackup="true"
android:icon="@drawable/ic_launcher"
android:label="@string/app_name"
android:theme="@style/AppTheme" >
<meta-data
android:name="com.baidu.lbsapi.API_KEY"
android:value="请输入你的Ak值" />

由于是第三方定位代码直接上：

// 定位初始化

mLocClient.registerLocationListener(myListener);

}

不显示图层，只获取当前城市
