需要用到的ITelephony.aidl：
package com.android.internal.telephony;
/**

* TelephonyManager class. A few places are still using this directly.
* Please clean them up if possible and use TelephonyManager instead.

* End call or go to the Home screen
* @return whether it hung up
*/
boolean endCall();
/**
* Answer the currently-ringing call.
*
* If there's already a current active call, that call will be
* automatically put on hold. If both lines are currently in use, the
* current active call will be ended.
*
* TODO: provide a flag to let the caller specify what policy to use
* if both lines are in use. (The current behavior is hardwired to
* "answer incoming, end ongoing", which is how the CALL button
* is specced to behave.)
*
* TODO: this should be a oneway call (especially since it's called
* directly from the key queue thread).
*/
void answerRingingCall();
/**
* Silence the ringer if an incoming call is currently ringing.
* (If vibrating, stop the vibrator also.)
*
* It's safe to call this if the ringer has already been silenced, or
* even if there's no incoming call. (If so, this method will do nothing.)
*
* TODO: this should be a oneway call too (see above).
* (Actually *all* the methods here that return void can
* probably be oneway.)
*/
void silenceRinger();
/**
* Allow mobile data connections.
*/
boolean enableDataConnectivity();
/**
* Disallow mobile data connections.
*/
boolean disableDataConnectivity();
/**
* Report whether data connectivity is possible.
*/
boolean isDataConnectivityPossible();
}
监听通话广播【PhoneReceiver.java】：
package com.ebupt.phonerecorddemo.server;
import android.app.Service;
import android.content.BroadcastReceiver;
import android.content.Context;
import android.content.Intent;
import android.telephony.TelephonyManager;
import android.util.Log;
public class PhoneReceiver extends BroadcastReceiver {
String TAG = "PhoneReceiver";
@Override
public void onReceive(Context context, Intent intent) {
TelephonyManager tm = (TelephonyManager) context
.getSystemService(Service.TELEPHONY_SERVICE);
switch (tm.getCallState()) {
case TelephonyManager.CALL_STATE_OFFHOOK:// 电话打进来接通状态；电话打出时首先监听到的状态。
Log.i("onCallStateChanged", "CALL_STATE_OFFHOOK");
break;
case TelephonyManager.CALL_STATE_RINGING:// 电话打进来状态
Log.i("onCallStateChanged", "CALL_STATE_RINGING");
PhoneUtils.autoAnswerPhone(context,tm);
break;
case TelephonyManager.CALL_STATE_IDLE:// 不管是电话打出去还是电话打进来都会监听到的状态。
Log.i("onCallStateChanged", "CALL_STATE_IDLE");
break;
}
}
}
在上面类适当的地方加上挂断或接通电话的代码即可。
最后别忘记在AndroidManifest.xml里声明和注册权限。

</uses-permission>
<uses-permission android:name="android.permission.PROCESS_OUTGOING_CALLS" >
