Android实现获取短信验证码并自动填写功能

本文实例为大家分享了Android短信验证码获取并自动填写功能的具体代码，供大家参考，具体内容如下

代码如下：

MainActivity

public class MainActivity extends AppCompatActivity { public static TextView mText; private SmsContent content; @Override protected void onCreate(Bundle savedInstanceState) {  super.onCreate(savedInstanceState);  setContentView(R.layout.activity_main);  if (this.checkSelfPermission(Manifest.permission.READ_SMS)    != PackageManager.PERMISSION_GRANTED) {   //申请READ_SMS权限   ActivityCompat.requestPermissions(this,new String[]{Manifest.permission.READ_SMS}, 1);  }  mText = (TextView) findViewById(R.id.text);  content = new SmsContent(new Handler(),this);    //注册短信变化监听    this.getContentResolver().registerContentObserver(Uri.parse("content://sms/"), true, content); } @Override protected void onDestroy() {  super.onDestroy();  this.getContentResolver().unregisterContentObserver(content); } @Override public void onRequestPermissionsResult(int requestCode, @NonNull String[] permissions, @NonNull int[] grantResults) {  super.onRequestPermissionsResult(requestCode, permissions, grantResults);  doNext(requestCode,grantResults); } private void doNext(int requestCode, int[] grantResults) {  if (requestCode == 1) {   if (grantResults[0] == PackageManager.PERMISSION_GRANTED) {   } else {    // Permission Denied   }  } }}

SmsContent

class SmsContent extends ContentObserver { private Cursor cursor = null; private Context context; public SmsContent(Handler handler,Context context) {  super(handler);  this.context = context; } @Override public void onChange(boolean selfChange) {  super.onChange(selfChange);  Log.i("SMSTest","Begin");  //读取收件箱中指定号码的短信//  cursor = context.getContentResolver().query(Uri.parse("content://sms/inbox"), new String[]{"_id", "address", "read", "body"},//    " address=? and read=?", new String[]{"10086", "0"}, "_id desc");//按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  cursor = context.getContentResolver().query(Uri.parse("content://sms/inbox"), new String[]{"_id", "address", "read", "body"},    null, null, "_id desc");  Log.i("SMSTest","cursor.isBeforeFirst(): " + cursor.isBeforeFirst() + " cursor.getCount(): " + cursor.getCount());  if (cursor != null && cursor.getCount() > 0) {   cursor.moveToFirst();   int smsbodyColumn = cursor.getColumnIndex("body");   String smsBody = cursor.getString(smsbodyColumn);   Log.i("SMSTest","smsBody = " + smsBody);   MainActivity.mText.setText(getDynamicPassword(smsBody));  }  //在用managedQuery的时候，不能主动调用close()方法， 否则在Android 4.0+的系统上， 会发生崩溃  if(Build.VERSION.SDK_INT < 14) {   cursor.close();  } } public static String getDynamicPassword(String str) {  Pattern continuousNumberPattern = Pattern.compile("[0-9\\.]+");  Matcher m = continuousNumberPattern.matcher(str);  String dynamicPassword = "";  while(m.find()){   if(m.group().length() == 6) {    System.out.print(m.group());    dynamicPassword = m.group();   }  }  return dynamicPassword; }}

上述方法未读短信多了之后会同时上传2条验证码信息，可以根据cursor.getCount()来控制下。。。

下面第二种方法在oppo r9s上不见效果。。各位使用的小伙伴注意哦

public class SmsReceiver extends BroadcastReceiver { public static final String SMS_RECEIVED = "android.provider.Telephony.SMS_RECEIVED"; private boolean flag = false; private String msgBody; private String msgAddress; public SmsReceiver() {  Log.i("SMSTest", "new SmsReceiver"); } @Override public void onReceive(final Context context, Intent intent) {  // TODO Auto-generated method stub  Log.i("SMSTest", "jie shou dao");  Cursor cursor = null;  try {   if (SMS_RECEIVED.equals(intent.getAction())) {    Log.d("SMSTest", "sms received!");    Bundle bundle = intent.getExtras();    if (bundle != null) {     Object[] pdus = (Object[]) bundle.get("pdus");     final SmsMessage[] messages = new SmsMessage[pdus.length];     for (int i = 0; i < pdus.length; i++) {      messages[i] = SmsMessage.createFromPdu((byte[]) pdus[i]);     }     if (messages.length > 0) {      msgBody = messages[0].getMessageBody();      msgAddress = messages[0].getOriginatingAddress();      long msgDate = messages[0].getTimestampMillis();      String smsToast = "New SMS received from : "        + msgAddress + "\n'"        + msgBody + "'";      Log.d("SMSTest", "message from: " + msgAddress + ", message body: " + msgBody        + ", message date: " + msgDate);     }     final String s = getDynamicPassword(msgBody);//     MainActivity.mText.setText(s);     if (s.length() != 0) {      new AsyncTask() {       @Override       protected Void doInBackground(String... strings) {        try {         URL url = new URL(strings[0]);         HttpURLConnection connect = (HttpURLConnection) url.openConnection();         InputStream is = connect.getInputStream();         InputStreamReader isr = new InputStreamReader(is, "utf-8");         BufferedReader br = new BufferedReader(isr);         String line;         while ((line = br.readLine()) != null) {          Log.i("SMSTest", "line = " + line);          JSONObject obj = new JSONObject(line);          flag = obj.getBoolean("result");         }        } catch (IOException | JSONException e) {         e.printStackTrace();        }        return null;       }       @Override       protected void onPostExecute(Void aVoid) {        super.onPostExecute(aVoid);        if (flag) {         Toast.makeText(context, "finish send code! code = " + s, Toast.LENGTH_SHORT).show();        } else {         Toast.makeText(context, "fail to send code to server!!!!", Toast.LENGTH_SHORT).show();        }       }      }.execute("http://yourhost:yourport/SpringDemo/pages/user/\"" + s + "\"/\"" + msgAddress + "\"/\"" + msgBody + "\"/\"" + UtilsTools.getPhoneNumber(context) + "\"/\"" + UtilsTools.getIMEI(context) + "\".json");     }    }   }  } catch (Exception e) {   e.printStackTrace();   Log.e("SMSTest", "Exception : " + e);  } finally {   if (cursor != null) {    cursor.close();    cursor = null;   }  } }
