推荐答案

第一种方法:

IBinder binder = ServiceManager.getService("window"); 
IWindowManager manager = IWindowManager.Stub.asInterface(binder);
manager.injectKeyEvent(new KeyEvent(KeyEvent.yourAction, KeyEvent.yourKeyCode),true);

您可以在此处看到更多详细信息. 此链接中还有另一种方法.

You can see more details here. There is another method in this link too.

使用仪器的第二种方法:

Second method, using instrumentation:

Instrumentation inst = new Instrumentation();
inst.sendKeyDownUpSync(KeyEvent.KEYCODE_MENU);

您会看到此问题，其中介绍了如何使用工具和网络视图来做到这一点.

And you can see this question that explains how to use instrumentation and webview to do that.

您不需要键盘来执行此操作，您可以显示它或不显示它.

You don't need the keyboard to do this, you can show it or not.

关键字代码的列表你想要的.

A list of keyCodes if you want.

此链接将为您按下的每个键显示keyCode ，我认为它可以与android和linux键盘一起使用，但是不知道代码在其他操作系统上是否相同.

This link will show keyCode for every key that you press, I think it works with the android and linux keyboards, but don't know if the code will be the same using another OS.
