android - 我可以自动发送短信吗(无需用户批准)

Question

我对 Android 比较陌生。我试图从 Android 应用程序发送短信。使用 SMS Intent 时，SMS 窗口打开，用户需要批准 SMS 并发送。

有没有办法在没有用户确认的情况下自动发送短信？

谢谢，利奥

您可以使用此方法发送短信。如果短信大于 160 个字符，则使用 sendMultipartTextMessage。

private void sendSms(String phonenumber,String message, boolean isBinary)
{
    SmsManager manager = SmsManager.getDefault();

    PendingIntent piSend = PendingIntent.getBroadcast(this, 0, new Intent(SMS_SENT), 0);
    PendingIntent piDelivered = PendingIntent.getBroadcast(this, 0, new Intent(SMS_DELIVERED), 0);

    if(isBinary)
    {
            byte[] data = new byte[message.length()];

            for(int index=0; index<message.length() && index < MAX_SMS_MESSAGE_LENGTH; ++index)
            {
                    data[index] = (byte)message.charAt(index);
            }

            manager.sendDataMessage(phonenumber, null, (short) SMS_PORT, data,piSend, piDelivered);
    }
    else
    {
            int length = message.length();

            if(length > MAX_SMS_MESSAGE_LENGTH)
            {
                    ArrayList<String> messagelist = manager.divideMessage(message);

                    manager.sendMultipartTextMessage(phonenumber, null, messagelist, null, null);
            }
            else
            {
                    manager.sendTextMessage(phonenumber, null, message, piSend, piDelivered);
            }
    }
}

更新

piSend 和 piDelivered 是 Pending Intent 他们可以在方法完成发送短信时触发广播

这是广播接收器的示例代码

    private BroadcastReceiver receiver = new BroadcastReceiver() {

        @Override
        public void onReceive(Context context, Intent intent) {
            String message = null;

            switch (getResultCode()) {
            case Activity.RESULT_OK:
                message = "Message sent!";
                break;
            case SmsManager.RESULT_ERROR_GENERIC_FAILURE:
                message = "Error. Message not sent.";
                break;
            case SmsManager.RESULT_ERROR_NO_SERVICE:
                message = "Error: No service.";
                break;
            case SmsManager.RESULT_ERROR_NULL_PDU:
                message = "Error: Null PDU.";
                break;
            case SmsManager.RESULT_ERROR_RADIO_OFF:
                message = "Error: Radio off.";
                break;
            }

            AppMsg.makeText(SendMessagesWindow.this, message,
                    AppMsg.STYLE_CONFIRM).setLayoutGravity(Gravity.BOTTOM)
                    .show();
      }
  };

您可以在 Activity 中使用以下行进行注册

registerReceiver(receiver, new IntentFilter(SMS_SENT));  // SMS_SENT is a constant

别忘了在 onDestroy 中注销广播

@Override
protected void onDestroy() {
    unregisterReceiver(receiver);
    super.onDestroy();
}
