  调用拨号界面，即使用startActivityForResult()也不会返回调用者界面，可变通方法取监听电话状态，在挂断后返回调用者.

  主要是透过

  TelephonyManager.listen(lsnr, PhoneStateListener.LISTEN_CALL_STATE); 注册监听callback

 

  private class PhoneCallListener extends PhoneStateListener {

        private boolean bphonecalling = false;

        @Override

        public void onCallStateChanged(int state, String incomingnumber) {

            // seems the incoming number is this call back always ""

            if (TelephonyManager.CALL_STATE_OFFHOOK == state) {

                bphonecalling = true;

            } else if (TelephonyManager.CALL_STATE_IDLE == state

                    && bphonecalling) {

                if (mTtelephonyManager != null) {

                    mTtelephonyManager.listen(mPhoneCallListener,

                            PhoneStateListener.LISTEN_NONE);

                }

                bphonecalling = false;

                

                Intent i = getPackageManager().getLaunchIntentForPackage(

                        getPackageName());

                i.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK

                        | Intent.FLAG_ACTIVITY_SINGLE_TOP);

                startActivity(i);

            }

            super.onCallStateChanged(state, incomingnumber);
