Question

当我的手机重新启动时，我尝试发送短信。我的代码正在进行活动，我可以在活动中获取发送报告。但是我在Broadcastreceiver中放了相同的代码，它无法正常工作。

                   try 
                     {

                        String SENT      = "SMS_SENT";


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

                    registerReceiver(new BroadcastReceiver() 
                    {
                        @Override
                        public void onReceive(Context arg0, Intent arg1) 
                        {
                            int resultCode = getResultCode();
                            switch (resultCode) 
                            {


                            case Activity.RESULT_OK:                 
                                 Toast.makeText(getBaseContext(), "SMS sent",Toast.LENGTH_LONG).show();
                                                                           break;
                            case SmsManager.RESULT_ERROR_GENERIC_FAILURE:  Toast.makeText(getBaseContext(), "Generic failure",Toast.LENGTH_LONG).show();
                                                                           break;
                            case SmsManager.RESULT_ERROR_NO_SERVICE:       Toast.makeText(getBaseContext(), "No service",Toast.LENGTH_LONG).show();
                                                                           break;
                            case SmsManager.RESULT_ERROR_NULL_PDU:         Toast.makeText(getBaseContext(), "Null PDU",Toast.LENGTH_LONG).show();
                                                                           break;
                            case SmsManager.RESULT_ERROR_RADIO_OFF:        Toast.makeText(getBaseContext(), "Radio off",Toast.LENGTH_LONG).show();
                                                                           break;
                            }
                        }
                    }, new IntentFilter(SENT));

                               SmsManager smsMgr = SmsManager.getDefault();
                               smsMgr.sendTextMessage(address, null,"Send sms", sentPI, null);

                                }
                     catch (Exception e) 
                     {
                        Toast.makeText(this, e.getMessage()+"!\n"+"Failed to send SMS", Toast.LENGTH_LONG).show();
                        e.printStackTrace();
                     }

如何在broadcastreceiver或服务中使用此代码？。

Answer 1

您无法在BroadcastReceiver中注册BroadcastReceiver，因为BroadcastReceiver的有效期不长（仅限于onReceive()的通话时间。所以您需要的是什么要做的是从Service开始BroadcastReceiver并让它发送短信。您所拥有的代码应该来自Service。

Answer 2

不要使用 SmsManager.RESULT_ERROR_GENERIC_FAILURE：，因为它已弃用，而是使用android.telephony.SmsManager Docs

重启后，请致电广播接收器：

import android.content.BroadcastReceiver;
import android.content.Context;
import android.content.Intent;

public class MyReceiver extends BroadcastReceiver {

  @Override
  public void onReceive(Context context, Intent intent) {
    Intent service = new Intent(context, YourService.class);
    context.startService(service);
  }
}

您的服务：

import android.app.Service;
import android.content.Intent;
import android.os.Bundle;
import android.os.IBinder;
import android.telephony.SmsManager;
import android.widget.Toast;

public class YourService extends Service {


 @Override
 public void onCreate() {

 }

 @Override
 public IBinder onBind(Intent arg0) {
  return null;
 }

 @Override
 public void onDestroy() {
   super.onDestroy();
 }

 @Override
 public void onStart(Intent intent, int startId) {
  super.onStart(intent, startId);

  //
  SmsManager smsManager = SmsManager.getDefault();
  smsManager.sendTextMessage(number to send , null, text, null, null);
 }

 @Override
 public boolean onUnbind(Intent intent) {

 }

}

确保您在清单文件中添加所需的权限，接收方和服务
