在ancivity中進行調用：
public void getLocation() {
LocationClient mLocationClient;
mLocationClient = ((LocationApplication) getApplication()).mLocationClient;
LocationMode tempMode = LocationMode.Hight_Accuracy;
String tempcoor = "gcj02";
LocationClientOption option = new LocationClientOption();
option.setLocationMode(tempMode);// 設置定位模式
option.setCoorType(tempcoor);// 返回的定位結果是百度經緯度，默認值gcj02
int span = 1000;
option.setScanSpan(span);// 設置發起定位請求的間隔時間爲5000ms
mLocationClient.setLocOption(option);
mLocationClient.start();
}
備註：經過實驗是可以得的出來的，但是有時候會出現
4.9e-324這樣子的。
這個說明程序沒問題，只是百度定位失敗的原因，只要換個容易定位的地方就ok了，4.9e-324是百度默認精讀，就是定位的時候，他返回的BDLocation裏字段latitude默認值。
記得在mianfest中配置這個
<service
android:name="com.baidu.location.f"
android:enabled="true"
android:permission="android.permission.BAIDU_LOCATION_SERVICE"
android:process=":remote" >
<intent-filter>
<action android:name="com.baidu.location.service_v2.1" />
</intent-filter>
</service>
還有導入相應的庫文件
