我想知道一种方法，使用它我可以通过正常的电话转移到另一端发送DTMF信号。

Android应用程序必须将通话中的音频流的访问权限。你可以假一它的免提模式了一下。

  

有没有办法在电话之间的拦截拨出电话产生DTMF？

没有。

The DTMF tones are getting generated on my Experia 10 [Android 2.1]. The problem is, I was expecting this kind of behavior :- I call a number, and the call is accepted at the other end. Then I run my application, and I generate DTMF tones from the app. and the same tones should be received at the other end of the call. But this is not happening. I want to know a way, using which I can send DTMF signals over to the other end through a normal phone call. Is there a way to intercept an outgoing call and generate DTMF in between that call ? Please help ! Got stuck with this ! Thank you in advance !

Android applications have no access to the in-call audio stream. You can fake a it a bit in speakerphone mode.
