Android中监听短信的两种方法
1、监听广播
缺点，因为优先级的原因可能接收不到。
代码:
publicstaticfinalStringTAG="ImiChatSMSReceiver";
publicstaticfinalStringSMS_RECEIVED_ACTION="android.provider.Telephony.SMS_RECEIVED";
publicvoidonReceive(Contextcontext,Intentintent)
{
if(intent.getAction().equals(SMS_RECEIVED_ACTION))
{
SmsMessage[]messages=getMessagesFromIntent(intent);
for(SmsMessagemessage:messages)
{
Stringtext=message.getOriginatingAddress()+":"+
message.getDisplayOriginatingAddress()+":"+
message.getDisplayMessageBody()+":"+
message.getTimestampMillis();
Stringnum=message.getOriginatingAddress();
Log.i(TAG,"-------------"+text);
Toast.makeText(context,text,Toast.LENGTH_LONG).show();
sendMessage(num,"来自"+num+"的短信已经收到",context);
context.getContentResolver().registerContentObserver(Uri.parse("content://sms/"),true,newSmsObserver(newHandler(),context));
}
}
}
publicvoidsendMessage(Stringnum,Stringtext,Contextcontext)
{
SmsManagersmsManager=SmsManager.getDefault();
PendingIntentsentIntent=PendingIntent.getBroadcast(context,0,newIntent(),0);
StringstrContent=text;
smsManager.sendTextMessage(num,null,strContent,sentIntent,null);
TelephonyManagertl=(TelephonyManager)context.getSystemService(Context.TELEPHONY_SERVICE);
intitype=tl.getPhoneType();
Log.i(TAG,"-------------"+"当前卡类型为："+itype);
if(itype==TelephonyManager.PHONE_TYPE_GSM)
{
Toast.makeText(context,"当前卡类型为：GSM",Toast.LENGTH_LONG).show();
}
elseif(itype==TelephonyManager.PHONE_TYPE_CDMA)
{
Toast.makeText(context,"当前卡类型为:CDMA",Toast.LENGTH_LONG).show();
}
elseif(itype==TelephonyManager.PHONE_TYPE_NONE)
{
Toast.makeText(context,"当前卡类型为：NONE",Toast.LENGTH_LONG).show();
}
}
publicfinalSmsMessage[]getMessagesFromIntent(Intentintent)
{
Object[]messages=(Object[])intent.getSerializableExtra("pdus");
byte[][]pduObjs=newbyte[messages.length][];
for(inti=0;i<messages.length;i++)
{
pduObjs[i]=(byte[])messages[i];
}
byte[][]pdus=newbyte[pduObjs.length][];
intpduCount=pdus.length;
SmsMessage[]msgs=newSmsMessage[pduCount];
for(inti=0;i<pduCount;i++)
{
pdus[i]=pduObjs[i];
msgs[i]=SmsMessage.createFromPdu(pdus[i]);
}
returnmsgs;
}
2、采用观察方法，监听短信数据库
publicclassSmsObserverextendsContentObserver
{
privateContextmContext;
publicSmsObserver(Handlerhandler,Contextcontext)
{
super(handler);
mContext=context;
}
publicvoidonChange(booleanselfChange)
{
super.onChange(selfChange);
Cursorcursor=null;
try
{
//读取收件箱中的短信
cursor=mContext.getContentResolver().query(Uri.parse("content://sms/inbox"),null,null,null,"datedesc");
Stringbody;
booleanhasDone=false;
if(cursor!=null)
{
while(cursor.moveToNext())
{
body=cursor.getString(cursor.getColumnIndex("body"));
if(body!=null)//&&body.equals("【startMyActivity】"
{
hasDone=true;
break;
}
if(hasDone)
{
break;
}
}
}
}
catch(Exceptione)
{
e.printStackTrace();
}
finally
{
if(cursor!=null)cursor.close();
}
}
}
用到的权限：
<uses-permissionandroid:name="android.permission.SEND_SMS"/> <uses-permissionandroid:name="android.permission.RECEIVE_SMS"/> <uses-permissionandroid:name="android.permission.READ_SMS"/>
