Question

我想显示我当前的位置，但它显示了我在命令行上设置的纬度和经度！如果我没有在命令行上设置参数，它会显示Eclipse中包含的纬度和经度！

有没有人对此有所了解？我正在测试AVD。

我做了一个测试，看看我的位置是否已启用，但事实并非如此。我不确定为什么会这样。

这是我的代码：

Answer 1

打开虚拟设备管理器并点按“编辑”。在硬件部分单击新建并添加GPS支持并将值更改为true。现在启动模拟器并打开控制台。如果模拟器已启动完成，请在控制台telnet localhost 5554中键入。建立telnet连接后，您可以放置如下位置：geo fix 21.42 42

Answer 2

要添加到现有答案，如果您确实需要在模拟器上测试功能，则可以使用模拟位置。你可以在这里找到更多http://developer.android.com/guide/topics/location/obtaining-user-location.html#MockData。

请注意，您必须为此添加所需的权限（ACCESS_MOCK_LOCATION）。

希望这有帮助！

Answer 3

除非您的PC / Mac具有GPS，否则AVD无法检测您的位置。使用真实设备或手动输入值来测试您的程序。
