以下是如何在android

中读取传入短信的分步说明

您需要使用广播接收器

在AndroidManifest中声明接收器

<receiver android:name=".IncomingSms">   
 <intent-filter>
     <action android:name="android.provider.Telephony.SMS_RECEIVED" />
 </intent-filter>

在AndroidManifest中提供阅读短信权限

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

AndroidManifest.xml文件的完整代码：

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="com.androidexample.broadcastreceiver"
    android:versionCode="1"
    android:versionName="1.0" >

    <application
        android:allowBackup="true"
        android:icon="@drawable/ic_launcher"
        android:label="@string/app_name"
        android:theme="@style/AppTheme" >
        <activity
            android:name="com.androidexample.broadcastreceiver.BroadcastNewSms"
            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="com.androidexample.broadcastreceiver.IncomingSms">   
            <intent-filter>
                <action android:name="android.provider.Telephony.SMS_RECEIVED" />
            </intent-filter>
        </receiver>

    </application>
    <uses-sdk
        android:minSdkVersion="8"
        android:targetSdkVersion="17" />

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

</manifest>

IncomingSms.java文件详细信息：我在这个文件中制作了广播事件接收器 1.使用扩展的BroadcastReceiver类创建类IncomingSms

public class IncomingSms extends BroadcastReceiver


  2. Get the object of SmsManager to find out received sms details

//获取SmsManager的对象

final SmsManager sms = SmsManager.getDefault();


  3.  Create method receiver()


public void onReceive(Context context, Intent intent)


    4. Get / Read current Incomming SMS data

//从意图中检索扩展数据的地图。

final Bundle bundle = intent.getExtras();

try {

    if (bundle != null) {

        final Object[] pdusObj = (Object[]) bundle.get("pdus");

        for (int i = 0; i < pdusObj.length; i++) {

            SmsMessage currentMessage = SmsMessage.createFromPdu((byte[]) pdusObj[i]);
            String phoneNumber = currentMessage.getDisplayOriginatingAddress();

            String senderNum = phoneNumber;
            String message = currentMessage.getDisplayMessageBody();

            Log.i("SmsReceiver", "senderNum: "+ senderNum + "; message: " + message);


           // Show alert
            int duration = Toast.LENGTH_LONG;
            Toast toast = Toast.makeText(context, "senderNum: "+ senderNum + ", message: " + message, duration);
            toast.show();

        } // end for loop
      } // bundle is null

} catch (Exception e) {
    Log.e("SmsReceiver", "Exception smsReceiver" +e);

}
