安卓使用Root权限实现后台模拟全局按键、触屏事件方法(类似按键精灵)
/** * 用root权限执行Linux下的Shell指令 * * @author jzj * @since 2014-09-09 */ public class RootShellCmd { private OutputStream os; /** * 执行shell指令 * * @param cmd * 指令 */ public final void exec(String cmd) { try { if (os == null) { os = Runtime.getRuntime().exec("su").getOutputStream(); } os.write(cmd.getBytes()); os.flush(); } catch (Exception e) { e.printStackTrace(); } } /** * 后台模拟全局按键 * * @param keyCode * 键值 */ public final void simulateKey(int keyCode) { exec("input keyevent " + keyCode + "\n"); } }
通过Runtime实现,代码如下:
- 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();
- }
这个代码是模拟菜单键,模拟其它按键只需将KeyEvent.KEYCODE_MENU替换成其它键值。
缺点:反应速度较慢
