Android 接收短信

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();
    }
}

 

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!
