android获取短信验证码并自动填写的实现一

android获取短信验证码并自动填写的实现一，有需要的朋友可以参考下。

现在的应用在注册登录或者修改密码中都用到了短信验证码，那在android中是如何实现获取短信验证码并自动填写的呢？

首先，需要要在manifest中注册接收和读取短信的权限:

<uses-permission android:name="android.permission.RECEIVE_SMS"></uses-permission>
<uses-permission android:name="android.permission.READ_SMS"/>

实现一个广播SMSBroadcastReceiver来监听短信：

package com.example.receive;

import java.text.SimpleDateFormat;
import java.util.Date;

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

/**
* 短信监听
* @author
*
*/
public class SMSBroadcastReceiver extends BroadcastReceiver {

private static MessageListener mMessageListener;
public static final String SMS_RECEIVED_ACTION = "android.provider.Telephony.SMS_RECEIVED";

public SMSBroadcastReceiver() {
super();
}

@Override
public void onReceive(Context context, Intent intent) {
if (intent.getAction().equals(SMS_RECEIVED_ACTION)) {
Object[] pdus = (Object[]) intent.getExtras().get("pdus");
for(Object pdu:pdus) {
SmsMessage smsMessage = SmsMessage.createFromPdu((byte [])pdu);
String sender = smsMessage.getDisplayOriginatingAddress();
//短信内容
String content = smsMessage.getDisplayMessageBody();
long date = smsMessage.getTimestampMillis();
Date tiemDate = new Date(date);
SimpleDateFormat simpleDateFormat = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");
String time = simpleDateFormat.format(tiemDate);

//过滤不需要读取的短信的发送号码
if ("+8613450214963".equals(sender)) {
mMessageListener.onReceived(content);
abortBroadcast();
}
}
}

}

//回调接口
public interface MessageListener {
public void onReceived(String message);
}

public void setOnReceivedMessageListener(MessageListener messageListener) {
this.mMessageListener = messageListener;
}
}

在需要填写验证码的Activity中，生产SMSBroadcastReceiver的实例，实现onReceived的回调接口。为了节约系统资源，我们使用动态注册注销广播的方法。

package com.example.smstest;

import com.example.receive.SMSBroadcastReceiver;

import android.os.Bundle;
import android.app.Activity;
import android.content.IntentFilter;
import android.view.Menu;
import android.widget.EditText;

public class MainActivity extends Activity {

private EditText edtPassword;
private SMSBroadcastReceiver mSMSBroadcastReceiver;

private static final String ACTION = "android.provider.Telephony.SMS_RECEIVED";

@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
edtPassword = (EditText) findViewById(R.id.password);
}

@Override
protected void onStart() {
super.onStart();
//生成广播处理
mSMSBroadcastReceiver = new SMSBroadcastReceiver();

//实例化过滤器并设置要过滤的广播
IntentFilter intentFilter = new IntentFilter(ACTION);
intentFilter.setPriority(Integer.MAX_VALUE);
//注册广播
this.registerReceiver(mSMSBroadcastReceiver, intentFilter);

mSMSBroadcastReceiver.setOnReceivedMessageListener(new SMSBroadcastReceiver.MessageListener() {
@Override
public void onReceived(String message) {

edtPassword.setText(message);

}
});
}

@Override
protected void onDestroy() {
super.onDestroy();
//注销短信监听广播
this.unregisterReceiver(mSMSBroadcastReceiver);
}

}
