Android 实现模拟按键

Android 实现模拟按键

参考：http://blog.csdn.net/aminfo/article/details/7785975

通过执行shell指令实现输出字符串：

public final void exec(String cmd) {
try {
    if (os == null) {
        os = Runtime.getRuntime().exec("su").getOutputStream();
    }
    os.write(cmd.getBytes());
    os.flush();
    if ((Runtime.getRuntime().exec("su").waitFor() != 0)) {

    throw new SecurityException();
    }


} catch (Exception e) {
    e.printStackTrace();
    }
}

通过键值输出单一字符：

public final void simulateKey(int keyCode) {
        exec("input keyevent " + keyCode + "\n");
}

将字符串拆分输入时，效率比较慢。
