Android自动获得短信验证码

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
}
@Override
protected void onPause() {
super.onPause();
getContentResolver().unregisterContentObserver(mObserver);//取消内容观察者注册
}
