通过Runtime实现，代码如下：
[html]view plain
copy
- try
- {
- String keyCommand = "input keyevent " + KeyEvent.KEYCODE_MENU;
- Runtime runtime = Runtime.getRuntime();
- Process proc = runtime.exec(keyCommand);
- }
- catch (IOException e)
- {
- // TODO Auto-generated catch block
- e.printStackTrace();
- }
缺点：反应速度较慢
