Android中实现基本的短信拦截功能的代码示例

要点

1.在Manifest.xml里加"接收"SMS的权限

<uses-permission Android:name="android.permission.RECEIVE_SMS"></uses-permission>

2.在Manifest.xml里注册一个receive

<!-- 注册Receiver,并且设置优先级 -->
    <receiver android:name=".AutoSMS" android:exported="false">
  <intent-filter android:priority="1000">
  <action android:name="android.provider.Telephony.SMS_RECEIVED"/>
  </intent-filter>
 </receiver>

3.定义一个短信接收类,并且重写onReceive

//继承BroadcastReceiver
public class AutoSMS extends BroadcastReceiver
{

 private String TAG="AutSMS";
 //广播消息类型
 public static final String SMS_RECEIVED_ACTION = "android.provider.Telephony.SMS_RECEIVED";
 //覆盖onReceive方法
 @Override
 public void onReceive(Context context, Intent intent)
 {
.....

实例
下面是完整的代码:

Manifest.xml:

<manifest xmlns:android="http://schemas.android.com/apk/res/android"
  package="com.xxh.autosms"
  android:versionCode="1"
  android:versionName="1.0" > 

  <uses-sdk
    android:minSdkVersion="8"
    android:targetSdkVersion="15" />
  <uses-permission android:name="android.permission.RECEIVE_SMS"/> 

  <application
    android:icon="@drawable/ic_launcher"
    android:label="@string/app_name"
    android:theme="@style/AppTheme" >
    <activity
      android:name=".MainActivity"
      android:label="@string/title_activity_main" >
      <intent-filter>
        <action android:name="android.intent.action.MAIN" /> 

        <category android:name="android.intent.category.LAUNCHER" />
      </intent-filter>
    </activity>
    <!-- 注册Receiver,并且设置优先级 -->
    <receiver android:name=".AutoSMS" android:exported="false">
      <intent-filter android:priority="1000">
        <action android:name="android.provider.Telephony.SMS_RECEIVED"/>
      </intent-filter>
    </receiver> 

  </application> 

</manifest>

AutoSMS.java:

    String action = intent.getAction();
    if (SMS_RECEIVED_ACTION.equals(action))
    {
      //获取intent参数
      Bundle bundle=intent.getExtras();
      //判断bundle内容
      if (bundle!=null)
      {

        }
        //解析完内容后分析具体参数
        for(SmsMessage msg:messages)
        {
          //获取短信内容
          String content=msg.getMessageBody();
          String sender=msg.getOriginatingAddress();
          Date date = new Date(msg.getTimestampMillis());
          SimpleDateFormat sdf = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");
          String sendTime = sdf.format(date);
          //TODO:根据条件判断,然后进一般处理
          if ("10060".equals(sender))
          {
            // 屏蔽手机号为10060的短信，这里还可以时行一些处理，如把这个信息发送到第三人的手机等等。
            //TODO:测试
            Toast.makeText(context, "收到10060的短信"+"内容:"+content, Toast.LENGTH_LONG).show();
            //对于特定的内容,取消广播
            abortBroadcast();
          }
          else
          {
            Toast.makeText(context, "收到:"+sender+"内容:"+content+"时间:"+sendTime.toString(), Toast.LENGTH_LONG).show();
          }
        } 

      }
    }//if 判断广播消息结束
