Android 接收短信

时间:2021-03-01 17:48:57

启动程序时启动一个service,在service里注册接收短信的广播,当手机收到短信里,打印出短信内容跟电话号码。

package com.lmy.SmsListener;

import android.app.Activity;
import android.content.Intent;
import android.os.Bundle;
import android.widget.TextView; public class SmsListenerActivity extends Activity { @Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
// setContentView(R.layout.main);
TextView tv = new TextView(this);
tv.setText("Hello. I started!");
setContentView(tv);
Intent service = new Intent(this, MyService.class);
this.startService(service);
}
}

当service被kill后,我们可以在开机时自动启动service。

开机自动启动一个service,在service里注册接收短信的广播,当手机收到短信里,打印出短信内容跟电话号码。

开机启动后系统会发出一个Standard Broadcast Action,名字叫android.intent.action.BOOT_COMPLETED,这个Action只会发出一次。

创建一个类继承BroadcastReceiver,在onReceive(Context context, Intent intent)里面启动service。

package com.lmy.SmsListener;

import android.content.BroadcastReceiver;
import android.content.Context;
import android.content.Intent;
import android.util.Log; public class MyBrocast extends BroadcastReceiver { static final String ACTION = "android.intent.action.BOOT_COMPLETED"; @Override
public void onReceive(Context context, Intent intent) {
Log.v("dimos", "MyBrocast");
if (intent.getAction().equals(ACTION)) {
Intent service = new Intent(context, MyService.class);
context.startService(service);
}
} }

在service中注册一个接收短信的广播:

package com.lmy.SmsListener;

import android.app.Service;
import android.content.Intent;
import android.content.IntentFilter;
import android.os.IBinder;
import android.util.Log; public class MyService extends Service { @Override
public IBinder onBind(Intent intent) {
return null;
} @Override
public void onCreate() {
super.onCreate();
IntentFilter localIntentFilter = new IntentFilter("android.provider.Telephony.SMS_RECEIVED");
localIntentFilter.setPriority(2147483647);
SmsRecevier localMessageReceiver = new SmsRecevier();
Log.v("dimos", "MyService");
registerReceiver(localMessageReceiver, localIntentFilter);
} }

广播接收到短信:

package com.lmy.SmsListener;

import android.content.BroadcastReceiver;
import android.content.Context;
import android.content.Intent;
import android.util.Log; public class SmsRecevier extends BroadcastReceiver { public SmsRecevier() {
super();
Log.v("dimos", "SmsRecevier create");
} @Override
public void onReceive(Context context, Intent intent) { String dString = SmsHelper.getSmsBody(intent);
String address = SmsHelper.getSmsAddress(intent);
Log.i("dimos", dString+","+address);
//阻止广播继续传递,如果该receiver比系统的级别高,
//那么系统就不会收到短信通知了 abortBroadcast();
}
}

获得短信内容跟短信地址:

package com.lmy.SmsListener;

import android.content.Intent;
import android.os.Bundle;
import android.telephony.SmsMessage; public class SmsHelper {
/**
* 获得短信内容
* */
public static String getSmsBody(Intent intent) { String tempString = "";
Bundle bundle = intent.getExtras();
Object messages[] = (Object[]) bundle.get("pdus");
SmsMessage[] smsMessage = new SmsMessage[messages.length];
for (int n = 0; n < messages.length; n++) {
smsMessage[n] = SmsMessage.createFromPdu((byte[]) messages[n]);
// 短信有可能因为使用了回车而导致分为多条,所以要加起来接受
tempString += smsMessage[n].getDisplayMessageBody();
}
return tempString; } /**
* 获得短信地址
* */
public static String getSmsAddress(Intent intent) { Bundle bundle = intent.getExtras();
Object messages[] = (Object[]) bundle.get("pdus");
return SmsMessage.createFromPdu((byte[]) messages[0])
.getDisplayOriginatingAddress();
}
}

在AndroidManifest.xml里声明并加权限:

<?xml version="1.0" encoding="utf-8"?>
<manifest
xmlns:android="http://schemas.android.com/apk/res/android"
package="com.lmy.SmsListener"
android:versionCode="1"
android:versionName="1.0">
<uses-sdk
android:minSdkVersion="7" /> <application
android:icon="@drawable/icon"
android:label="@string/app_name">
<activity
android:name=".SmsListenerActivity"
android:label="@string/app_name">
<intent-filter>
<action
android:name="android.intent.action.MAIN" />
<category
android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity> <receiver
android:name="MyBrocast"
android:enabled="true">
<intent-filter>
<action
android:name="android.intent.action.BOOT_COMPLETED" />
</intent-filter> </receiver>
<service android:name="MyService"></service> </application>
<uses-permission
android:name="android.permission.RECEIVE_SMS" /><!-- 接收短信权限 -->
<!-- 添加接收系统启动消息(用于开机启动)权限 -->
<uses-permission
android:name="android.permission.RECEIVE_BOOT_COMPLETED" />
</manifest>

这样就可以获得接收到的短信了,赶快试下吧!
