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);
	}

}
