Android Combat Simple Tutorial-the 36th gun (listen to SMS-implementation of SMS Verification code automatically fill in)

General users like to use mobile phone number as a user name to register the app account, this is usually through the verification code of mobile phone verification, the following we study a very practical method, through the monitoring of SMS-SMS Verification code automatically fill in, improve the user experience.
First, let's look at how to listen to SMS.

First, to obtain the entire content of text messages

1. Create a new smsbroadcastreceiver:

 PackageCom.example.messagecut;ImportJava.text.SimpleDateFormat;ImportJava.util.Date;ImportAndroid.content.BroadcastReceiver;ImportAndroid.content.Context;ImportAndroid.content.Intent;ImportAndroid.telephony.SmsMessage;/** * Configure the Broadcast receiver: * <receiver android:name= ". Smsbroadcastreceiver "> * <intent-filter android:priority=" + "> * <action android:name=" ANDROID.P Rovider. Telephony.sms_received "/> * </intent-filter> * </receiver> * * NOTE: * <intent-filter Android:prio rity= "+" > means: * Set this broadcast receiver to the highest level */ Public  class smsbroadcastreceiver extends broadcastreceiver {    Private StaticMessageListener Mmessagelistener; Public Smsbroadcastreceiver() {Super(); }@Override     Public void OnReceive(context context, Intent Intent) {Object [] pdus= (object[]). Intent.getextras (). Get ("PDUs"); for(Object Pdu:pdus) {Smsmessage SMSMESSAGE=SMSMESSAGE.CREATEFROMPDU (byte[]) PDU);                String sender=smsmessage.getdisplayoriginatingaddress (); String Content=smsmessage.getmessagebody ();LongDate=smsmessage.gettimestampmillis (); Date timedate=NewDate (date); SimpleDateFormat simpledateformat=NewSimpleDateFormat ("Yyyy-mm-dd HH:mm:ss");                String Time=simpledateformat.format (timedate); System.out.println ("SMS from:"+sender); System.out.println ("message content:"+content); System.out.println ("SMS Time:"+time); mmessagelistener.onreceived (content);//If the text message comes from 5556 and no longer passes down, this number can be used as the SMS platform number.                 if("5556". Equals (Sender) {System.out.println ("Abort");                Abortbroadcast (); }             }    }//Callback interface         Public  interface messagelistener {             Public void onreceived(String message); } Public void Setonreceivedmessagelistener(MessageListener MessageListener) { This. Mmessagelistener=messagelistener; }}

2. Configure the Androidmanifest.xml file:

<?xml version= "1.0" encoding= "Utf-8"?><manifest xmlns:android="Http://schemas.android.com/apk/res/android"  package ="Com.example.messagecut"android:versioncode="1"android:versionname ="1.0" >                <uses-sdkandroid:minsdkversion="8"android:targetsdkversion ="/>"                     <applicationandroid:allowbackup="true"android:icon="@drawable/ Ic_launcher "android:label=" @string/app_name "android:theme=" @style/apptheme " >                                        <activityandroid:name=". Mainactivity "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=". Smsbroadcastreceiver ">          <intent-filter >              <action android:name="Android.provider.Telephony.SMS_RECEIVED"/>          </intent-filter>            </receiver>    </Application>    <uses-permission android:name="Android.permission.RECEIVE_SMS"/>     <uses-permission android:name="Android.permission.READ_SMS"/></manifest>

3. Create mainactivity.java-to receive the text message content displayed:

 PackageCom.example.messagecut;ImportAndroid.os.Bundle;ImportAndroid.widget.TextView;ImportCom.example.messagecut.SMSBroadcastReceiver.MessageListener;Importandroid.app.Activity;/** * Demo Description: * Use Broadcastreceiver to implement listening SMS * * NOTE permission: * <uses-permission android:name= "android.permission.RECEIVE_ SMS "/> * * Details: * http://blog.csdn.net/lfdfhl/article/details/8195400 * * * * * Public  class mainactivity extends Activity{    PrivateTextView Mtextview;PrivateSmsbroadcastreceiver Msmsbroadcastreceiver;@Override    protected void onCreate(Bundle savedinstancestate) {Super. OnCreate (Savedinstancestate);        Setcontentview (R.layout.activity_main);    Init (); }Private void Init() {mtextview= (TextView) Findviewbyid (R.id.textview); Msmsbroadcastreceiver=NewSmsbroadcastreceiver (); Msmsbroadcastreceiver.setonreceivedmessagelistener (NewMessageListener () { Public void onreceived(String message)            {mtextview.settext (message);    }        }); }}

4. layout file is simple, TextView is used to display text message content:

<relativelayout xmlns:android="Http://schemas.android.com/apk/res/android"xmlns:tools="Http://schemas.android.com/tools"Android:layout_width="Match_parent"android:layout_height="Match_parent"Android:paddingbottom="@dimen/activity_vertical_margin"android:paddingleft="@dimen/activity_horizontal_margin"android:paddingright="@dimen/activity_horizontal_margin"android:paddingtop="@dimen/activity_vertical_margin"tools:context="Com.example.messagecut.MainActivity"> <textview android:id="@+Id/textview"Android:layout_width="Wrap_content"android:layout_height="Wrap_content"android:text="@string/hello_world"/></relativelayout>

5. Run the project on the real phone and then send a message with another phone to get the following:

Intercepted the text message content.

Second, intercept the verification code

The above implementation of the interception of all text messages, below we see how to intercept effective information-verification code. The principle should be simple to intercept part of a string in a string.
The algorithm is:

/** * Intercept consecutive 6-digit combinations ([0-9]{"+ 6 +"}) from a string to intercept six-bit numbers before and after assertions cannot appear numbers used to get dynamic passwords from text messages * * @param str * SMS Content * @return captured 6-bit dynamic password */       PublicStringGetdynamicpassword(String str) {//6 is the number of digits of the verification code is generally six bitsPattern Continuousnumberpattern = Pattern.compile ("(? <![ 0-9]) ([0-9]{"+6+"}) (?! [0-9]) ");        Matcher m = continuousnumberpattern.matcher (str); String Dynamicpassword =""; while(M.find ())          {System.out.print (M.group ());        Dynamicpassword = M.group (); }returnDynamicpassword; }

In the mainactivity:

 PackageCom.example.messagecut;ImportAndroid.os.Bundle;ImportAndroid.widget.EditText;ImportAndroid.widget.TextView;ImportJava.util.regex.Matcher;ImportJava.util.regex.Pattern;ImportCom.example.messagecut.SMSBroadcastReceiver.MessageListener;Importandroid.app.Activity;/** * Demo Description: * Use Broadcastreceiver to implement listening SMS * * NOTE permission: * <uses-permission android:name= "android.permission.RECEIVE_ SMS "/> * * * * * * * * Public  class mainactivity extends Activity{    PrivateEditText Mcode;PrivateSmsbroadcastreceiver Msmsbroadcastreceiver;@Override    protected void onCreate(Bundle savedinstancestate) {Super. OnCreate (Savedinstancestate);        Setcontentview (R.layout.activity_main);    Init (); }Private void Init() {mcode= (EditText) Findviewbyid (R.id.et_code); Msmsbroadcastreceiver=NewSmsbroadcastreceiver (); Msmsbroadcastreceiver.setonreceivedmessagelistener (NewMessageListener () { Public void onreceived(String message) {Mcode.settext (Getdynamicpassword (message));//intercept 6-digit verification Code}        }); }/** * Intercept consecutive 6-digit combinations ([0-9]{"+ 6 +"}) from a string to intercept six-bit numbers before and after assertions cannot appear numbers used to get dynamic passwords from text messages * * @param str * SMS Content * @return captured 6-bit dynamic password */       PublicStringGetdynamicpassword(String str) {//6 is the number of digits of the verification code is generally six bitsPattern Continuousnumberpattern = Pattern.compile ("(? <![ 0-9]) ([0-9]{"+6+"}) (?! [0-9]) ");        Matcher m = continuousnumberpattern.matcher (str); String Dynamicpassword =""; while(M.find ())          {System.out.print (M.group ());        Dynamicpassword = M.group (); }returnDynamicpassword; }}

Here we also modified the Activity_main.xml file, changed TextView to EditText, because Android phone users may prohibit the app access to text messages should be supported by manual fill.
