我想显示我的当前位置，但它显示我在命令行上设置的纬度和经度!如果我不在命令行上设置参数，它会显示 Eclipse 中包含的经纬度!

有没有人对此有想法？我正在用 AVD 进行测试。

我进行了测试以查看我的位置是否已启用，但未启用。我不确定为什么会这样。

这是我的代码:

最佳答案

打开您的虚拟设备管理器并单击“编辑”。在 Hardware 部分单击 New 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。 如果模拟器启动完成，请在控制台中键入 telnet localhost 5554。 建立 telnet 连接后，您可以放置​​如下位置:geo fix 21.42 42
