【移動(dòng)應(yīng)用開發(fā)技術(shù)】Android開發(fā)中短信觸發(fā)的示例分析

本篇文章為大家展示了Android開發(fā)中短信觸發(fā)的示例分析，內(nèi)容簡(jiǎn)明扼要并且容易理解，絕對(duì)能使你眼前一亮，通過這篇文章的詳細(xì)介紹希望你能有所收獲。Android中BroadCastReceiver可以用來偵聽廣播事件。在使用Broadcast之前，必須使用代碼或是在AndroidManifest.xml進(jìn)行注冊(cè)。下面的例子實(shí)現(xiàn)使用短信來觸發(fā)AndroidGraphics2DTutorial中的示例。短信格式為：@demo:xxxx

,xxxx為

示例名稱，比如，啟動(dòng)Colors示例，則向手機(jī)發(fā)送：@demo:Colors.手機(jī)在收到短信后，先檢測(cè)短信格式是否符合

@demo:xxxx,若符合，這啟動(dòng)對(duì)應(yīng)的示例。在AndroidGraphics2DTutorial中添加一個(gè)自定義的BroadcastReceiver

SmsMessageReceiver用于監(jiān)測(cè)接受到的短信：public

class

SmsMessageReceiver

extends

BroadcastReceiver

{

private

static

final

String

queryString="@demo:";

@Override

public

void

onReceive(Context

context,

Intent

intent)

{

Bundle

extras

=

intent.getExtras();

if

(extras

==

null)

return;

Object[]

pdus

=

(Object[])

extras.get("pdus");

for

(int

i

=

0;

i

<

pdus.length;

i++)

{

SmsMessage

message

=

SmsMessage.createFromPdu((byte[])

pdus[i]);

String

fromAddress

=

message.getOriginatingAddress();

String

fromDisplayName

=

fromAddress;

String

msg=message.getMessageBody();

if(msg.startsWith(queryString)){

//

Trigger

the

main

activity

to

fire

up

a

dialog

//that

shows/reads

the

received

messages

Intent

di

=

new

Intent();

di.setClass(context,

AndroidGraphics2DTutorial.class);

di.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK

|

Intent.FLAG_ACTIVITY_SINGLE_TOP);

di.putExtra(AndroidGraphics2DTutorial.SMS_FROM_ADDRESS_EXTRA,

fromAddress);

di.putExtra(AndroidGraphics2DTutorial.SMS_FROM_DISPLAY_NAME_EXTRA,

fromDisplayName);

di.putExtra(AndroidGraphics2DTutorial.SMS_MESSAGE_EXTRA,

msg);

context.startActivity(di);

}

}

}

}onReceive會(huì)在Broadcast事件發(fā)生是執(zhí)行，這里檢測(cè)短信內(nèi)容，如果是以@demo:開頭的，則啟動(dòng)AndroidGraphics2DTutorialMainActivity。修改AndroidMainifest.xml<receiver

android:name=".SmsMessageReceiver"

android:enabled="true">

<intent-filter>

<action

android:name="vider.Telephony.SMS_RECEIVED"

/>

</intent-filter>

</receiver>同時(shí)添加permission，和JavaME類似Android某些API需要指定對(duì)應(yīng)的Permission才可以使用。<uses-permission

android:name="android.permission.SEND_SMS"

/>

<uses-permission

android:name="android.permission.RECEIVE_SMS"

/>修改AndroidGraphics2DTutorial.java來處理SMS消息：public

void

onCreate(Bundle

savedInstanceState)

{

super.onCreate(savedInstanceState);

Resources

res

=

getResources();

String[]

activity_Names

=

res.getStringArray(R.array.activity_name);

String[]

activity_Infos

=

res.getStringArray(R.array.activity_info);

for(int

i=0;i<activity_Names.length;i++){

ActivityInfo

activityInfo=new

ActivityInfo();

activityInfo.activityName=activity_Names[i];

activityInfo.activityInfo=activity_Infos[i];

activityInfo.iconIndex=R.drawable.icon1+i;

activityInfos.add(activityInfo);

}

aa=new

ActivityInfoAdapter(this,R.layout.activitylist,activityInfos);

setListAdapter(aa);

Bundle

bundle=getIntent().getExtras();

if(bundle!=null){

mFromAddress

=

bundle.getString(SMS_FROM_ADDRESS_EXTRA);

mMessage

=

bundle.getString(SMS_MESSAGE_EXTRA);

int

index=mMessage.indexOf(queryString);

if(index>=0){

String

demoName=mMessage.substring(index+queryString.length());

Intent

intent

=

new

Intent();

intent.setClassName(this,

packgeName+".example."

+demoName);

startActivity(intent);
