android获取短信验证码并自动填写

参考资料如下，亲测很好用，哈哈：

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;    }}

实际使用并没有用以上方法，因为未读短信多了之后会同时上传2条验证码信息
