Android实现自动填充短信验证码
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
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
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(); } }
以上就是本文的全部内容,希望对大家的学习有所帮助,也希望大家多多支持我们。
