当任何来电按下拒绝按钮时，我想执行一些操作。我已经阅读了官方文档TelephonyManager但它不能满足我的需要。

我试过这个没有成功。

public class Call_Receiver extends BroadcastReceiver {

    private Context ctx;

    @Override
    public void onReceive(Context context, Intent intent) {
        ctx = context;
        OutgoingIncomingCallListener phoneListener = new OutgoingIncomingCallListener();
        TelephonyManager telephony = (TelephonyManager) context
                .getSystemService(Context.TELEPHONY_SERVICE);

        if (intent.getAction()
                .equals("android.intent.action.NEW_OUTGOING_CALL")) {
            telephony.listen(phoneListener,
                    PhoneStateListener.LISTEN_CALL_STATE);
        }

    }

    class OutgoingIncomingCallListener extends PhoneStateListener {
        public boolean wasRinging;

        @Override
        public void onCallStateChanged(int state, String incomingNumber) {
            switch (state) {
            case TelephonyManager.CALL_STATE_RINGING:
                wasRinging = true;
                break;
            case TelephonyManager.CALL_STATE_OFFHOOK:
                Log.i("", "  ***********  OFFHOOK  ********");
                wasRinging = true;
                break;
            case TelephonyManager.CALL_STATE_IDLE:
                if (wasRinging) {
                    Toast.makeText(ctx,
                            "Your call is disconnected by receiver", 10000)
                            .show();
                }
                wasRinging = true;
                break;
            }
        }
    }
}

当接收者拒绝来电时，它会向我展示敬酒，但我想从来电者一方这样做。
所以我只想找到当有人按下拒绝按钮来接听任何来电时的事件。

我该怎么做呢？
