Android自动 验证码 短信 填充
2023-06-13 09:12:27 时间

大家好，又见面了，我是你们的朋友全栈君。

一、前言：

这周项目做优化，为用户操作更加方便，注册、忘记密码、更换手机号、所需要的获取验证码操作，增加 获取短信验证码，然后自动填写到输入框中。思路简单，主要是监听短信的广播，然后正则短信中的验证码

二、具体代码：

package com.taikongdan.app.service;

import android.content.BroadcastReceiver;
import android.content.Context;
import android.content.Intent;
import android.telephony.SmsMessage;

import java.util.regex.Matcher;
import java.util.regex.Pattern;

/**

 */
public class SMSReceiver extends BroadcastReceiver {
    public static final String SMS_RECEIVED_ACTION = "android.provider.Telephony.SMS_RECEIVED";
    public static final String TAG = "ImiChatSMSReceiver";

    public interface ISMSListener {
        void onSmsReceiver(String verifyCode);
    }

    private static ISMSListener mSMSListener;

    public SMSReceiver(ISMSListener mSMSListener) {
        this.mSMSListener = mSMSListener;
    }

    @Override
    public void onReceive(Context context, Intent intent) {
        if (intent.getAction().equals(SMS_RECEIVED_ACTION)) {
            SmsMessage[] messages = getMessageFromIntent(intent);
            for (SmsMessage message : messages
                    ) {
            //  在这里你可以对放松的号码进行判断，只接受目标号码的验证码
                String msg = message.getDisplayMessageBody();
                Pattern p = Pattern.compile("\\d{6}");//这里你可以更改数字来指定验证码的位数
                Matcher m = p.matcher(msg);
                String verifyCode = null;
                while (m.find()) {
                    verifyCode = m.group();
                    break;
                }
                if (mSMSListener != null) {
                    mSMSListener.onSmsReceiver(verifyCode);
                }

            }

        }
    }

    private SmsMessage[] getMessageFromIntent(Intent intent) {
        Object[] messages = (Object[]) intent.getSerializableExtra("pdus");
        byte[][] pduObjes = new byte[messages.length][];
        for (int i = 0; i < messages.length; i++) {
            pduObjes[i] = ((byte[]) messages[i]);

        }
        byte[][] pdus = new byte[pduObjes.length][];
        int pduCount = pdus.length;
        SmsMessage[] msgs = new SmsMessage[pduCount];
        for (int i = 0; i < pduCount; i++) {
            pdus[i] = pduObjes[i];
            msgs[i] = SmsMessage.createFromPdu(pdus[i]);
        }
        return msgs;
    }
}

在Activity onCreate中，注册广播， 

<pre name="code" class="java">    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.rememeberactivity);
        mReceiver = new SMSReceiver(this);
        IntentFilter filter = new IntentFilter();
        filter.addAction("android.provider.Telephony.SMS_RECEIVED");
        registerReceiver(mReceiver, filter);

    }

在界面销毁的时候 解绑广播 

    @Override
    protected void onDestroy() {
        super.onDestroy();
        unregisterReceiver(mReceiver);
    }
