android獲取短信驗證碼並自動填寫的實現一

現在的應用在註冊登錄或者修改密碼中都用到了短信驗證碼，那在android中是如何實現獲取短信驗證碼並自動填寫的呢？

首先，需要要在manifest中註冊接收和讀取短信的權限:

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

實現一個廣播SMSBroadcastReceiver來監聽短信： 

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;


/**
 * 短信監聽
 * @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();
	                //短信內容
	                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);

	                //過濾不需要讀取的短信的發送號碼
	                if ("[phone]".equals(sender)) {
	                    mMessageListener.onReceived(content);
	                    abortBroadcast();
	                }
	            }
	        }
	    
	}
	
	//回調接口
    public interface MessageListener {
        public void onReceived(String message);
    }
    
    public void setOnReceivedMessageListener(MessageListener messageListener) {
        this.mMessageListener = messageListener;
    }
}

在需要填寫驗證碼的Activity中，生產SMSBroadcastReceiver的實例，實現onReceived的回調接口。爲了節約系統資源，我們使用動態註冊註銷廣播的方法。 

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();
        //生成廣播處理
        mSMSBroadcastReceiver = new SMSBroadcastReceiver();

        //實例化過濾器並設置要過濾的廣播
        IntentFilter intentFilter = new IntentFilter(ACTION);
        intentFilter.setPriority(Integer.MAX_VALUE);
        //註冊廣播
        this.registerReceiver(mSMSBroadcastReceiver, intentFilter);

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

            	edtPassword.setText(message);

            }
        });
    }
	
	@Override
	protected void onDestroy() {
		super.onDestroy();
		 //註銷短信監聽廣播
        this.unregisterReceiver(mSMSBroadcastReceiver);
	}
}

第二種方法是通過監聽短信庫的變化,使用 短信觀察者

ContentObserver c=new ContentObserver(han) {
                @Override
                public void onChange(boolean selfChange) {
                    // TODO Auto-generated method stub
                    super.onChange(selfChange);
                    han.sendEmptyMessage(0);
                }
            };
getContentResolver().registerContentObserver(Uri.parse("content://sms"), true, c);


Handler han = new Handler() {
        @SuppressWarnings("deprecation")
        public void handleMessage(android.os.Message msg) {
            String codestr = null;
            try {
                codestr = Cus_UnitTools.getsmsyzm(Reg_ForgetPassword.this);
                code.setText(codestr);
                requestcode();
            } catch (Exception e) {
                Log.e("yung", "驗證碼提取失敗:" + codestr);
            }
        };
    };

    public static String getsmsyzm(Activity c) {
        Uri uri = Uri.parse("content://sms/inbox");
        String[] projection = new String[] { "address", "person", "body" };
        String selection = " address='" + JTPHONE + "' ";
        String[] selectionArgs = new String[] {};
        String sortOrder = "date desc";
        @SuppressWarnings("deprecation")
        Cursor cur = c.managedQuery(uri, projection, selection, selectionArgs,
                sortOrder);
        if(cur!=null&&cur.getCount()>0){
            cur.moveToFirst();
            String body = cur.getString(cur.getColumnIndex("body")).replaceAll(
                    "\n", " ");
            cur.close();
            return getyzm(body, YZMLENGTH);
    }
        cur.close();
        return null;
    }


        /**
     * 從短信字符竄提取驗證碼
     * @param body 短信內容
         * @param YZMLENGTH  驗證碼的長度 一般6位或者4位
     * @return 接取出來的驗證碼
     */
    public static String getyzm(String body, int YZMLENGTH) {
        // 首先([a-zA-Z0-9]{YZMLENGTH})是得到一個連續的六位數字字母組合
        // (?<![a-zA-Z0-9])負向斷言([0-9]{YZMLENGTH})前面不能有數字
        // (?![a-zA-Z0-9])斷言([0-9]{YZMLENGTH})後面不能有數字出現
        Pattern p = Pattern
                .compile("(?<![a-zA-Z0-9])([a-zA-Z0-9]{" + YZMLENGTH + "})(?![a-zA-Z0-9])");
        Matcher m = p.matcher(body);
        if (m.find()) {
            System.out.println(m.group());
            return m.group(0);
        }
        return null;
    }
