字号:
byte[] smscontentdb = smscontentemp.getBytes("gbk"); <br> byte[] smscontent = new byte[smscontentdb.length + temp.length]; <br> System.arraycopy(smscontentdb, 0, smscontent, 0, smscontentdb.length); <br> System.arraycopy(temp, 0, smscontent, smscontentdb.length, temp.length); <br> SendSMS sendSMS = new SendSMS(); <br> sendSMS.SmsInit(); <br> if (sendSMS.SmsSend(mobileno, smscontent) >= 0) { <br> System.out.println("chenggong !"); <br> } <br> else { <br> System.out.println("shibai !"); <br> } <br> }catch (Exception ex) {} <br> } <br>}</p> <br><br> 在这个文件中要注意的有一点，就是在传递字节数组到C程序中时，最后的结尾一定要以0结束。这是一个偷懒的做法，不过是个有效的做法。因为大多数情况下，接口是由第三方提供的。所以我们一般是不知道在C的方法里，具体是怎么处理参数的。而C又是要求数组是有长度。所以，在Java中，如果你不想写程序传数组的长度，那么在数组中以0结尾就是最方便的方法了。当然，如果有更好的方法也希望大家提出。<br><br> 到这里，一个完整的Java通过JNI调用动态链接库的程序就完成了。实际上也不是很复杂。只要多注意一下细节，是很容易得出来的。 <BR clear=all></font></td></tr>
