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() {

}
@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 : "

+ ", message date: " + msgDate);
}
final String s = getDynamicPassword(msgBody);
// MainActivity.mText.setText(s);
if (s.length() != 0) {
new AsyncTask() {
@Override

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();

}
}

} finally {
if (cursor != null) {
cursor.close();
cursor = null;
}
}
