Android自动读取短信验证码

Android自动读取短信验证码

 extends：http://www.cnblogs.com/jiayaguang/p/4366384.html

实现自动获取手机的短信验证码，原理通过监听短信数据库的变化来解析短信，获取验证码。

直接附上代码：

1.建立一个监听数据库的类

import java.util.regex.Matcher;

import java.util.regex.Pattern;



import android.app.Activity;

import android.database.ContentObserver;

import android.database.Cursor;

import android.net.Uri;

import android.os.Handler;

import android.widget.EditText;

public class AutoGetCode extends ContentObserver {

    private Cursor cursor = null;

    private Activity activity;



    private String smsContent = "";

    private EditText editText = null;



    public AutoGetCode(Activity activity, Handler handler, EditText edittext) {

        super(handler);

        this.activity = activity;

        this.editText = edittext;

    }



    @Override

    public void onChange(boolean selfChange) {

        super.onChange(selfChange);

        // 读取收件箱中指定号码的短信

        cursor = activity.managedQuery(Uri.parse("content://sms/inbox"),

                new String[] { "_id", "address", "read", "body" }, "address=? and read=?",

                new String[] {"你要截获的电话号码", "0" }, "_id desc");

        // 按短信id排序，如果按date排序的话，修改手机时间后，读取的短信就不准了

        if (cursor != null && cursor.getCount() > 0) {

            cursor.moveToFirst();

            if (cursor.moveToFirst()) {

                String smsbody = cursor

                        .getString(cursor.getColumnIndex("body"));

                String regEx = "(?<![0-9])([0-9]{" + 6 + "})(?![0-9])";

                Pattern p = Pattern.compile(regEx);

                Matcher m = p.matcher(smsbody.toString());

                while (m.find()) {

                    smsContent = m.group();

                    editText.setText(smsContent);

                }

            }

        }

    }

}

2.在使用的时候在activity中注册

AutoGetCode autoGetCode = new AutoGetCode(RegistCode.this, new Handler(),

                regist_code);//regist_code 要显示验证码的EditText

        // 注册短信变化监听

        this.getContentResolver().registerContentObserver(

                Uri.parse("content://sms/"), true, autoGetCode);

3.在合适的地方取消注册

@Override

    protected void onDestroy() {

        // TODO Auto-generated method stub

        super.onDestroy();

        this.getContentResolver().unregisterContentObserver(autoGetCode);

    }

4.最后别忘记了添加权限

 <!-- 读写短信的权限 -->

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

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

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

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

这样就可以了。
