我正在尝试在 android 中构建一个文本消息传递应用程序，代码有效，但唯一的错误是我无法使用 DDMS 向模拟器发送消息。我已经在下面粘贴了我的代码，以防万一，我在
之后立即截图了package com.example.oghenekaroedoh.sms;
import android.content.BroadcastReceiver;
import android.content.Context;
import android.content.Intent;
import android.os.Bundle;
import android.telephony.SmsMessage;
import android.util.Log;

public class SMSReceiver extends BroadcastReceiver {
@Override
public void onReceive(Context context, Intent intent)
{
//---get the SMS message passed in---
Bundle bundle = intent.getExtras();
SmsMessage[] msgs = null;
String str = "SMS from ";
if (bundle != null)
{
//---retrieve the SMS message received---
Object[] pdus = (Object[]) bundle.get("pdus");
msgs = new SmsMessage[pdus.length];
for (int i=0; i<msgs.length; i++){
msgs[i] = SmsMessage.createFromPdu((byte[])pdus[i]);
if (i==0) {
//---get the sender address/phone number---
str += msgs[i].getOriginatingAddress();
str += ": ";
}
//---get the message body---
str += msgs[i].getMessageBody().toString();
}
//---display the new SMS message---
Toast.makeText(context, str, Toast.LENGTH_SHORT).show();
Log.d("SMSReceiver", str);
}
}
}
这是 Activity 的代码，将此代码粘贴到另一个文件中..

这是 DDMS 输出的样子:
这里的主要问题是电话操作的单选按钮不可点击。有人请帮我解决这个问题
