Question

我需要一些方法来检测Linux上的鼠标/键盘活动。我需要记录此活动并使用tcp socket将此记录发送到我的Android平板电脑。我在终端中运行这个程序，它在线程“main”中显示错误Exception java.lang.UnsupportedClassVersionError：Mouse：Unsupported major.minor version 51.0..any help ????

}
String line, s = null;
try {
    while ((line = br.readLine()) != null) {
        prev_p = p;
        p = MouseInfo.getPointerInfo().getLocation();

             String[] arr = line.split(" ");
             if (arr.length == 8)
             s = arr[7];

            try {

            } catch (IOException e) {

    }
} catch (IOException e) {

}

我不会详细介绍如何使用tcp套接字，这很简单。

然而，您的问题的基础是您需要打开并不断读取/ dev / input / by-id / yourmouseorkeyboardnamehere文件。读取此文件将导致程序阻塞，直到有键盘/鼠标输入（取决于您是否读取键盘或鼠标文件），然后您将能够读取表示来自键盘或鼠标的数据的数据。

从那里通过tcp套接字向平板电脑发送这些数据相当容易，您可以从互联网上的任何套接字教程中学习。

如果您有任何疑问或需要更多详细信息，请发表评论。
