我有一个关于在 android 中发送短信的问题。我有两节课。其中一个是 SendMessage.java，另一个是 SendingSms.java，我想通过 SendingSms.java 文件发送我的消息，所以里面有一个 sendSms 类，我想在 SendMessage.java 文件中使用这个 sendSms 函数，但它不能不是。此外，我可以使用 SendingSms.java 中的函数，但是当我在其中编写发送短信代码时，它不起作用。有什么问题？

这是我的 SendMessage.java 中的函数

public void sendMessageButton (View view)
{
    //SendingSms send = new SendingSms();       
    if(who_detail.getText().toString().length()>0 && message_text.getText().toString().length()>0 )
    {
        sendSMS(who_detail.getText().toString(), message_text.getText().toString());

    }
    else
    {
    Toast.makeText(getApplicationContext(), R.string.sendingsms_error, Toast.LENGTH_LONG).show();
    }


}

这是我的 sendinSms.java

package com.example.stildeneme;

import android.app.Activity;
import android.app.PendingIntent;
import android.content.BroadcastReceiver;
import android.content.Context;
import android.content.Intent;
import android.content.IntentFilter;
import android.telephony.SmsManager;
import android.widget.Toast;

public class SendingSms extends Activity {

     public void sendSMS(String telNo, String mesaj)
        {
            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);

            registerReceiver(new BroadcastReceiver() {

                @Override
                public void onReceive(Context arg0, Intent arg1) {
                    // TODO Auto-generated method stub
                    switch(getResultCode())
                    {
                    case Activity.RESULT_OK:
                        Toast.makeText(getBaseContext(), "SMS Gönderildi",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));


            registerReceiver(new BroadcastReceiver(){
                @Override
                public void onReceive(Context arg0, Intent arg1) {
                    switch (getResultCode())
                    {
                        case Activity.RESULT_OK:
                            Toast.makeText(getBaseContext(), "SMS iletildi",
                                    Toast.LENGTH_SHORT).show();
                            break;
                        case Activity.RESULT_CANCELED:
                            Toast.makeText(getBaseContext(), "SMS iletilemedi",
                                    Toast.LENGTH_SHORT).show();
                            break;
                    }
                }

            }, new IntentFilter(DELIVERED));       

            SmsManager sms = SmsManager.getDefault();
            sms.sendTextMessage(telNo, null, mesaj, sentPI, deliveredPI);

         Toast.makeText(getApplicationContext(), telNo.toString() + " - " + mesaj.toString(), Toast.LENGTH_LONG).show();
        }

}

顺便说一句，我从 SendingSms 类扩展了我的 SendMessage 类。

将该方法设为您将从另一个活动中访问的公共静态方法。然后将其称为 activity1.sendsms();

就是这样。如果您发布代码会为您提供更好的建议...希望这会对您有所帮助。

嗨使用下面的代码。问题是你需要使用上下文。 

import android.app.Activity;
import android.app.PendingIntent;
import android.content.BroadcastReceiver;
import android.content.Context;
import android.content.Intent;
import android.content.IntentFilter;
import android.os.Bundle;
import android.telephony.SmsManager;
import android.widget.Toast;

public class SendingSms extends Activity {

    static Context context;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        // TODO Auto-generated method stub
        super.onCreate(savedInstanceState);
        context=this;

    }

     public static void sendSMS(String telNo, String mesaj)
        {
            String SENT = "SMS_SENT";
            String DELIVERED = "SMS_DELIVERED";

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

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

            context.registerReceiver(new BroadcastReceiver() {

                @Override
                public void onReceive(Context arg0, Intent arg1) {
                    // TODO Auto-generated method stub
                    switch(getResultCode())
                    {
                    case Activity.RESULT_OK:
                        Toast.makeText(context, "SMS Gönderildi",Toast.LENGTH_SHORT).show();
                        break;
                    case SmsManager.RESULT_ERROR_GENERIC_FAILURE:
                         Toast.makeText(context, "Generic failure",Toast.LENGTH_SHORT).show();
                         break;
                    case SmsManager.RESULT_ERROR_NO_SERVICE:
                         Toast.makeText(context, "No service",Toast.LENGTH_SHORT).show();
                         break;
                    case SmsManager.RESULT_ERROR_NULL_PDU:
                        Toast.makeText(context, "Null PDU",Toast.LENGTH_SHORT).show();
                        break;                  
                    case SmsManager.RESULT_ERROR_RADIO_OFF:
                        Toast.makeText(context, "Radio off",Toast.LENGTH_SHORT).show();
                        break;
                    }
                }
            }, new IntentFilter(SENT));


            context. registerReceiver(new BroadcastReceiver(){
                @Override
                public void onReceive(Context arg0, Intent arg1) {
                    switch (getResultCode())
                    {
                        case Activity.RESULT_OK:
                            Toast.makeText(context, "SMS iletildi",
                                    Toast.LENGTH_SHORT).show();
                            break;
                        case Activity.RESULT_CANCELED:
                            Toast.makeText(context, "SMS iletilemedi",
                                    Toast.LENGTH_SHORT).show();
                            break;
                    }
                }

            }, new IntentFilter(DELIVERED));       

            SmsManager sms = SmsManager.getDefault();
            sms.sendTextMessage(telNo, null, mesaj, sentPI, deliveredPI);

         Toast.makeText(context, telNo.toString() + " - " + mesaj.toString(), Toast.LENGTH_LONG).show();
        }

首先在您的 sendMessage.java 中初始化该类

sendinsms sm=新的 sendinsms();

sm.sendsms(你的参数);

首先，您缺少一个权限：

> Caused by: java.lang.SecurityException: Sending SMS message: User
> 10048 does not have android.permission.SEND_SMS.

其次，这种方法不应该static——你可能有内存泄漏。

如果您 SendMessage 扩展 SendSms 您应该公开 SendSms.sendSms 方法并且它应该可以工作

你不应该使用：static Context context;

context应该是一个正常的字段。为什么你需要它:>？您可以使用activity context

您可以通过两种方式进行：

1.将存在该方法的活动的上下文传递给您要调用该方法的其他活动。

2.第二种方法是使方法静态，然后使用类名从其他活动调用它。操作员

例如：

Class_Name.method()
