我创建了一个服务和广播接收器来获得电话状态.

以下是我的代码:

 @Override
    public int onStartCommand(Intent intent, int flags, int startId) {
        final IntentFilter filter = new IntentFilter();
        filter.addAction(ACTION_OUT);
        filter.addAction(ACTION_IN);

                            inCall=bundle.getString(TelephonyManager.EXTRA_INCOMING_NUMBER);
                            wasRinging = true;
                            Toast.makeText(context, "IN : " + inCall, Toast.LENGTH_LONG).show();
                        }
                    }
                    if(state.equals(TelephonyManager.EXTRA_STATE_OFFHOOK)){ …
