Android短信管理器不发送短信

Question

我是Android新手.我想点击发送按钮后发送短信

1. 首先我使用短信经理api.

package com.example.smsproject;
import android.app.Activity;
import android.content.Intent;
import android.os.Bundle;
import android.telephony.SmsManager;
import android.view.View;`enter code here`
import android.view.View.OnClickListener;
import android.widget.Button;
import android.widget.EditText;
import android.widget.Toast;

public class Page2Activity extends Activity {

  Button button;
  EditText textPhoneNo;
  @Override
  public void onCreate(Bundle savedInstanceState) {
      super.onCreate(savedInstanceState);
      setContentView(R.layout.main);

      button = (Button) findViewById(R.id.button1);
      textPhoneNo = (EditText) findViewById(R.id.mobilenumber);

      button.setOnClickListener(new OnClickListener() {

          @Override

      public void onClick(View v){

      //String phoneNo = textPhoneNo.getText().toString();
      String phoneNo = "tel:xxxxxxxxxx";
      String messageText = "SMS FROM ANDROID";
      try {
          SmsManager smsManager = SmsManager.getDefault();
          smsManager.sendTextMessage(phoneNo, null, messageText, null, null);
          Toast.makeText(getApplicationContext(), "SMS Sent Successfully!",
                      Toast.LENGTH_LONG).show();
      }catch (Exception e){

          Toast.makeText(getApplicationContext(),
                  "SMS failed, please try again later ! ",
                  Toast.LENGTH_LONG).show();
          e.printStackTrace();

      }

          }

      });

  }

}

1. 在android_manifest.xml上设置send_sms权限

我得到零错误,但短信不发送.如果你知道答案.

请让我知道,谢谢你的阅读.

Answer 1

完成@Android Fanatic的回答

如果文本太长,则消息不会消失,您必须根据编码来考虑最大长度.

更多信息可以在这里找到.

我更喜欢这种方法

SmsManager sms = SmsManager.getDefault();
ArrayList<String> parts = sms.divideMessage(message);

ArrayList<PendingIntent> sendList = new ArrayList<>();
sendList.add(sentPI);

ArrayList<PendingIntent> deliverList = new ArrayList<>();
deliverList.add(deliveredPI);

sms.sendMultipartTextMessage(phoneNumber, null, parts, sendList, deliverList);

Answer 2

此外，如果英文文本的消息长度超过 160，16 位字母文本的消息长度超过 70，SMS 管理器也不会发送消息。尝试发送简短的英文文本，看看是否是这种情况。（您可以发送多条消息来发送长文本）。

使用以下代码发送短信消息,此处错误将显示在Toast中

--sends an SMS message to another device---
private void sendSMS(String phoneNumber, String message)
{        
    String SENT = "SMS_SENT";
    String DELIVERED = "SMS_DELIVERED";

    PendingIntent sentPI = PendingIntent.getBroadcast(this, 0,
        new Intent(SENT), 0);

    PendingIntent deliveredPI = PendingIntent.getBroadcast(this, 0,
        new Intent(DELIVERED), 0);

    //---when the SMS has been sent---
    registerReceiver(new BroadcastReceiver(){
        @Override
        public void onReceive(Context arg0, Intent arg1) {
            switch (getResultCode())
            {
                case Activity.RESULT_OK:
                    Toast.makeText(getBaseContext(), "SMS sent", 
                            Toast.LENGTH_SHORT).show();
                    break;
                case SmsManager.RESULT_ERROR_GENERIC_FAILURE:
                    Toast.makeText(getBaseContext(), "Generic failure", 
                            Toast.LENGTH_SHORT).show();
                    break;
                case SmsManager.RESULT_ERROR_NO_SERVICE:
                    Toast.makeText(getBaseContext(), "No service", 
                            Toast.LENGTH_SHORT).show();
                    break;
                case SmsManager.RESULT_ERROR_NULL_PDU:
                    Toast.makeText(getBaseContext(), "Null PDU", 
                            Toast.LENGTH_SHORT).show();
                    break;
                case SmsManager.RESULT_ERROR_RADIO_OFF:
                    Toast.makeText(getBaseContext(), "Radio off", 
                            Toast.LENGTH_SHORT).show();
                    break;
            }
        }
    }, new IntentFilter(SENT));

    //---when the SMS has been delivered---
    registerReceiver(new BroadcastReceiver(){
        @Override
        public void onReceive(Context arg0, Intent arg1) {
            switch (getResultCode())
            {
                case Activity.RESULT_OK:
                    Toast.makeText(getBaseContext(), "SMS delivered", 
                            Toast.LENGTH_SHORT).show();
                    break;
                case Activity.RESULT_CANCELED:
                    Toast.makeText(getBaseContext(), "SMS not delivered", 
                            Toast.LENGTH_SHORT).show();
                    break;                        
            }
        }
    }, new IntentFilter(DELIVERED));        

    SmsManager sms = SmsManager.getDefault();
    sms.sendTextMessage(phoneNumber, null, message, sentPI, deliveredPI);        
}

Answer 4

String incomming = "9876543210";
android.telephony.SmsManager sms=android.telephony.SmsManager.getDefault();
sms.sendTextMessage(incomming, null,"Here Is Sms", null, null);
