动态与静态广播截取短信

 

通俗理解动态与静态广播监听

动态广播监听是在Activity,通过代码调用registerReceiver和unregisterReceiver来注册或者释注销听对象

表态广播监听是在AndoridMainfest.xml文件去注册一个广播监听,由系统去注销监听

总结:动态与静态如何区分,捉住是通过代码还是.xml去配置

 

动态注册短信监听

需求:我有一个注册页面,里面有个验证码字段是会发送到手机,我要在activity里监听验证短信并获取验证码

注:要接收短信监听,要授于短信接收的用户权限<uses-permissionandroid:name="android.permission.RECEIVE_SMS"/>

  然后注册广播

package com.test.testmsg;

import android.net.Uri;
import android.os.Bundle;
import android.app.Activity;
import android.content.BroadcastReceiver;
import android.content.Context;
import android.content.Intent;
import android.content.IntentFilter;
import android.telephony.SmsMessage;
import android.util.Log;

public class MainActivity extends Activity {
    //表示接收短信广播
    public static final String SMS_RECEIVED_ACTION = "android.provider.Telephony.SMS_RECEIVED";
    
    //定义广播监听者
    private BroadcastReceiver receiver = new BroadcastReceiver() {
        
        @Override
        public void onReceive(Context context, Intent intent) {
            // TODO Auto-generated method stub
            String action = intent.getAction();
       //过滤广播,如果是接收信息的广播则做处理,否则不处理
if(action.equals(SMS_RECEIVED_ACTION)){ Bundle bundle = intent.getExtras(); if(bundle != null){ // 取消广播(这行代码将会让系统收不到短信) //abortBroadcast(); //pdu为承载着一条短信的所有短信。 //一条短信为140个英文字符长度,在这个长度范围内,即需一个pdu即可。超出这个范围,即要分割成多个pdu数组。 Object[] pdus = (Object[]) bundle.get("pdus"); for(Object pdu : pdus){ SmsMessage smsMessage = SmsMessage.createFromPdu((byte[])pdu); String address = smsMessage.getOriginatingAddress(); String body = smsMessage.getMessageBody(); Log.i("KwokTag", address + " " + body); }
            //然后你可以截取短信中的验证码,通过handle发送一个消息让主线程的验证码填入验证码区域
            /** ....... */
} } } }; @Override
protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_main); //getLocalMsg(); IntentFilter filter = new IntentFilter(); filter.addAction(SMS_RECEIVED_ACTION); this.registerReceiver(receiver, filter); }   //在Activity销毁时要注销监听器 @Override protected void onDestroy() { // TODO Auto-generated method stub this.unregisterReceiver(receiver); super.onDestroy(); } }

 

静态注册短信监听

package com.test.testmsg;

import android.content.BroadcastReceiver;
import android.content.Context;
import android.content.Intent;
import android.os.Bundle;
import android.telephony.SmsMessage;
import android.util.Log;

public class MsgReceiver extends BroadcastReceiver {
    
    public static final String SMS_RECEIVED_ACTION = "android.provider.Telephony.SMS_RECEIVED";public MsgReceiver() {
        
    }

    @Override
    public void onReceive(Context context, Intent intent) {
        // TODO: This method is called when the BroadcastReceiver is receiving
        // an Intent broadcast.
        String action = intent.getAction();
        if(action.equals(SMS_RECEIVED_ACTION)){
            Bundle bundle = intent.getExtras();
            if(bundle != null){
                //pdu为承载着一条短信的所有短信。
                //一条短信为140个英文字符长度,在这个长度范围内,即需一个pdu即可。超出这个范围,即要分割成多个pdu数组。
                Object[] pdus =  (Object[]) bundle.get("pdus");
                for(Object pdu : pdus){
                    SmsMessage smsMessage = SmsMessage.createFromPdu((byte[])pdu);
                    String address = smsMessage.getOriginatingAddress();
                    String body = smsMessage.getMessageBody();
                    Log.i("KwokTag", address + " " + body);
                }
            }
        }
    }
}

 

写一个广播监听,实现监听处理,然后在AndroidMainfest配置如下

     <receiver
            android:name="com.test.testmsg.MsgReceiver"
            android:enabled="true"
            android:exported="true" >
            <intent-filter> 
                <action android:name="android.provider.Telephony.SMS_RECEIVED" /> 
            </intent-filter>
        </receiver>

这样也是可以实现短信监听,其实在onReceive里面可以不用再判断if(action.equals(SMS_RECEIVED_ACTION)),因为我们添加了intent-filter,已经帮我们过虑其它广播类型了。
