Android自动读取短信验证码

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;/** * 监听短信数据库，自动获取短信验证码 *  * @author 贾亚光 * @date 2015-3-25 * */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。
