本文实例为大家分享了Android自动填充短信验证码的具体代码,供大家参考,具体内容如下
短信验证码是大部分软件里面都存在的功能,同时为了避免用户自己输入导致的繁琐操作,有一部分app设计者将其设置成了自动填充的方式,方便用户操作那么这种方式是什么实现的呢。
利用广播接收器来拦截短信获取其中匹配的内容,提供回掉,将短信内容暴露到activity中实现自动填充
首先我们要实现一个广播接收器
代码语言:javascript复制package com.wquant.weilt.reciver;
import java.util.regex.Matcher;
import java.util.regex.Pattern;
import android.content.BroadcastReceiver;
import android.content.Context;
import android.content.Intent;
import android.os.Bundle;
import android.os.Message;
import android.telephony.SmsMessage;
import android.text.TextUtils;
import android.util.Log;
public class SmsReciver extends BroadcastReceiver {
private String patternCoder = "(?<!d)d{6}(?!d)";
@Override
public void onReceive(Context context, Intent intent) {
//获取短信数据
Object[] objs = (Object[]) intent.getExtras().get("pdus");
for (Object obj : objs) {
byte[] pdu = (byte[]) obj;
//将字节数组封装成为smsmessage对象
SmsMessage sms = SmsMessage.createFromPdu(pdu);
//获得短短信内容
String message = sms.getMessageBody();
Log.d("短信内容", "message:" message);
// 短息的手机号。。 86开头?
String from = sms.getOriginatingAddress();
Log.d("短信来源", "from :" from);
if (!TextUtils.isEmpty(from)) {
String code = patternCode(message);
if (!TextUtils.isEmpty(code)) {
mMessageListener.onReceived(code);
}
}
}
}
/**
* 匹配短信中间的6个数字(验证码等)
*
* @param patternContent
* @return
*/
private String patternCode(String patternContent) {
if (TextUtils.isEmpty(patternContent)) {
return null;
}
Pattern p = Pattern.compile(patternCoder);
Matcher matcher = p.matcher(patternContent);
if (matcher.find()) {
return matcher.group();
}
return null;
}
// 回调接口
public interface MessageListener {
public void onReceived(String message);
}
MessageListener mMessageListener;
public void setOnReceivedMessageListener(MessageListener messageListener) {
this.mMessageListener = messageListener;
}
}
ok上面我们已经实现了广播接收器,在activity中我们要绑定一个意图过滤器并将此广播注册在destory方法中要将其解除注册
代码语言:javascript复制package com.wquant.weilt.controler;
import org.apache.http.Header;
import org.json.JSONException;
import org.json.JSONObject;
import android.content.Intent;
import android.content.IntentFilter;
import android.os.Bundle;
import android.os.CountDownTimer;
import android.view.KeyEvent;
import android.view.View;
import android.widget.Button;
import android.widget.EditText;
import android.widget.ImageView;
import android.widget.TextView;
import android.widget.Toast;
import com.loopj.android.http.RequestParams;
import com.wquant.weilt.MyApplication;
import com.wquant.weilt.R;
import com.wquant.weilt.control.base.JsonHttpResponseHandlerBase;
import com.wquant.weilt.control.base.MyBaseActivity;
import com.wquant.weilt.reciver.SmsReciver;
import com.wquant.weilt.reciver.SmsReciver.MessageListener;
import com.wquant.weilt.util.CToast;
import com.wquant.weilt.util.CommonUtil;
import com.wquant.weilt.util.Constant;
import com.wquant.weilt.util.HttpUtil;
/**
* 修改密码
*
* @author zhaomy

*/
public class RestartLoginOrTradPwdActivity extends MyBaseActivity {
SmsReciver reciver;
@Override
protected void onCreate(Bundle savedInstanceState) {
// TODO Auto-generated method stub
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_restart_login_or_trad);
init();
}
private void init() {
code = (EditText) findViewById(R.id.register_code);
reciver=new SmsReciver();
IntentFilter filter = new IntentFilter();
// 设置短信拦截参数
filter.addAction("android.provider.Telephony.SMS_RECEIVED");
//设置最大优先级
filter.setPriority(Integer.MAX_VALUE);
registerReceiver(reciver, filter);
reciver.setOnReceivedMessageListener(new MessageListener() {
@Override
public void onReceived(String message) {
code.setText(message);
}
});
}
@Override
protected void onPause() {
super.onPause();
}
@Override
protected void onDestroy() {
unregisterReceiver(reciver);
super.onDestroy();
}
}
