gps没有获取用户位置

我想获取当前用户位置（经度和纬度），但onLocationChanged方法不会被称为但其他方法如public void onProviderDisabled（String provider）。请帮忙，可能是什么问题？我有一个类：gps没有获取用户位置

已经刺激了GPS坐标，通过DDMS模拟器或telnet命令。 – Dinash 2011-06-02 04:56:39

嗨迪尼什我试着在设备上三星galexy s其他方法正在调用bt当我按下一个图标显示，gps正在搜索bt it剂量显示任何信息 – amrut1 2011-06-02 05:12:01

它在它的工作正常仿真程序....如果是的话，检查互联网连接，并检查是否GPS启用...还检查GPS坐标是否被钩... – Dinash 2011-06-02 05:17:00

      "LocationProvider.OUT_OF_SERVICE", Toast.LENGTH_SHORT).show(); 
         } 

}

} 这是我的代码我用这对于获取用户当前位置。仔细阅读它，检查你在代码中犯的错误。，并检查与gps相关的mainfest文件中的所有权限。

<uses-permission android:name="android.permission.ACCESS_GPS" /> 
<uses-permission android:name="android.permission.ACCESS_LOCATION" /> 
<uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION" /> 
<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" />

我希望这是帮助。

只是扩展了GpsStatus.Listener您的活动。类似如下： ublic类MyActivity实现LocationListener的， GpsStatus.Listener

，并检查您的权限：
