android广播监听短信并显示内容

AndroidManifest.xml中添加

<receiver android:name=".receive">           
            <intent-filter>
                <action android:name="android.provider.Telephony.SMS_RECEIVED" />
            </intent-filter>
        </receiver>
<uses-permission android:name="android.permission.RECEIVE_SMS"></uses-permission>
<uses-permission android:name="android.permission.READ_SMS"></uses-permission>

再写一个广播监听

public class receive extends BroadcastReceiver
{
    String receiveMsg = "";
    public void onReceive(Context context, Intent intent)
    {
        SmsMessage[] msg= null;
         
     if (intent.getAction().equals("android.provider.Telephony.SMS_RECEIVED"))
     {
          //StringBuilder buf = new StringBuilder();
          Bundle bundle = intent.getExtras();
          if (bundle != null) {
                  Object[] pdusObj = (Object[]) bundle.get("pdus");
                  msg= new SmsMessage[pdusObj.length];
                  for (int i = 0; i<pdusObj.length; i++)
                          msg[i] = SmsMessage.createFromPdu ((byte[]) pdusObj[i]);
          }
     
      
     for(int i = 0; i < msg.length; i++)
     {
         String msgTxt = msg[i].getMessageBody();
         if (msgTxt.equals("Testing!"))
         {
             Toast.makeText(context, "success!", Toast.LENGTH_LONG).show();
             return;
         }
         else
         {
             Toast.makeText(context, msgTxt, Toast.LENGTH_LONG).show();
             return;
         }
     }
       return;
}
 
 
}
