android - 在android中访问短信的电话号码

Question

我是 android 的新手，我正在尝试在收到新消息时获取短信的号码，为此我正在使用广播接收器。但是当一条新消息出现时，我的“广播接收者”类无法正常工作。谁能帮我找出问题所在。在下面给出我的代码..

public class MainActivity extends Activity
{
     @Override
    protected void onCreate(Bundle savedInstanceState) 
    {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.test_layout);
    }


     public class MyBroadcastReciever extends BroadcastReceiver
{

    @Override
    public void onReceive(Context context, Intent intent) 
    {
        Bundle bundle = intent.getExtras();        
        SmsMessage[] msgs = null;
        String smsnumber = "";         
        if (bundle != null)
        {
            //---retrieve the sender number SMS received---
            Object[] pdus = (Object[]) bundle.get("pdus");
            msgs = new SmsMessage[pdus.length];            
            for (int i=0; i<msgs.length; i++)
            {
                msgs[i] = SmsMessage.createFromPdu((byte[])pdus[i]);                
                smsnumber =  msgs[i].getOriginatingAddress();         
            }
        } 
    }
}

}

我已经在 list 中给出了接收标签。

 <receiver android:name="com.aucupa.iack.MyBroadcastReciever" >
    <intent-filter>
        <action android:name="android.provider.Telephony.SMS_RECEIVED" />
    </intent-filter>
</receiver>

也获得了接收短信的使用权限..

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

但是当短信来自 MyBroadcastReciever 类时没有响应。当我调试控件时，控件没有到达 MyBroadcastReciever 类。请帮我找出问题

终于在大家的帮助下得到了答案，在这里给出我的答案..

 public class MainActivity extends Activity
{

  MyBroadcastReciever broadcastreciever = new MyBroadcastReciever();
  static final String SOME_ACTION = "android.provider.Telephony.SMS_RECEIVED";
  IntentFilter intentFilter = new IntentFilter(SOME_ACTION);

  Intent i = new Intent(SOME_ACTION);
 @Override
protected void onCreate(Bundle savedInstanceState) 
{
super.onCreate(savedInstanceState);
setContentView(R.layout.test_layout);

sendBroadcast(i);
context.registerReceiver(broadcastreciever, intentFilter);
}


 public class MyBroadcastReciever extends BroadcastReceiver
{

@Override
public void onReceive(Context context, Intent intent) 
{
   if (intent.getAction() == "android.provider.Telephony.SMS_RECEIVED"){
    Bundle bundle = intent.getExtras();        
    SmsMessage[] msgs = null;
    String smsnumber = "";         
    if (bundle != null)
    {
        //---retrieve the sender number SMS received---
        Object[] pdus = (Object[]) bundle.get("pdus");
        msgs = new SmsMessage[pdus.length];            
        for (int i=0; i<msgs.length; i++)
        {
            msgs[i] = SmsMessage.createFromPdu((byte[])pdus[i]);                
            smsnumber =  msgs[i].getOriginatingAddress();         
        }
    } 
 }
}
}

}

在扩展 BroadcastReceiver 的 MyBroadcastReciever 中，在 onReceive() 中尝试这段代码

 if (intent.getAction() == android.provider.Telephony.SMS_RECEIVED) {
                Bundle bundle = intent.getExtras();
                if (bundle != null) {
                       // your rest of code

                }
            }
