Android自动获得短信验证码

1：<!--动态读取手机短信权限--><uses-permission android:name="android.permission.READ_SMS" />2：编写内容观察者类，监听短信触发：public class SmsObserver extends ContentObserver {    private Context mContext;    private Handler mHandler;    public SmsObserver(Context context, Handler handler) {        super(handler);        mContext = context;        mHandler = handler;    }    @Override    public void onChange(boolean selfChange, Uri uri) {        super.onChange(selfChange, uri);        Log.e("DEBUG", "SMS has changed!");        Log.e("DEBUG", uri.toString());        String code = "";        if (uri.toString().equals("content://sms/raw")) {            return;        }        Uri inboxUri = Uri.parse("content://sms/inbox");        Cursor c = mContext.getContentResolver().query(inboxUri, null, null, null, "date desc");        if (c != null) {            if (c.moveToFirst()) {                String address = c.getString(c.getColumnIndex("address"));//获得发件人                String body = c.getString(c.getColumnIndex("body"));//发件内容                //即发送短信的号码               if (!address.equals("10690067200453")) {                    return;                }                Log.e("DEBUG", "发件人为：" + address + " " + "短信内容为：" + body);                Pattern pattern = Pattern.compile("(\\d{6})");//通过正则表达式获得六位数验证码                Matcher matcher = pattern.matcher(body);                if (matcher.find()) {                    code = matcher.group(0);                    Log.e("DEBUG", "code is " + code);                    //发送通过Register.MSG_RECEIVED_CODE发送code到实现类                    mHandler.obtainMessage(Register.MSG_RECEIVED_CODE, code).sendToTarget();                }            }            c.close();        }    }}3：实现类：public class Register extends Activity {    private EditText codeText;//验证码框    public static final int MSG_RECEIVED_CODE = 1;    private SmsObserver mObserver;    private Handler mHandler = new Handler() {        @Override        public void handleMessage(Message msg) {            if (msg.what == MSG_RECEIVED_CODE) {                String code = (String)msg.obj;                codeText.setText(code);            }        }    };    @Override    protected void onCreate(Bundle savedInstanceState) {        super.onCreate(savedInstanceState);        setContentView(R.layout.activity_register);        //动态获取短信验证码        mObserver = new SmsObserver(Register.this, mHandler);        Uri uri = Uri.parse("content://sms");        getContentResolver().registerContentObserver(uri, true, mObserver);//注册短信内容观察者}@Overrideprotected void onPause() {    super.onPause();    getContentResolver().unregisterContentObserver(mObserver);//取消内容观察者注册}4：图片：![短信验证码](http://img.blog.csdn.net/20151120222027525)
