and my code is

myProgressDialog = ProgressDialog.show(Shout.this,"","Loading...",true);

         new Thread() 
         {
         public void run()
         {
             String xml;



                 xml="<spGetUserMessages><SearchLocation></SearchLocation></spGetUserMessages>";
                 messages =parse.GetGetUserMessages(dataparsing.ILGetUserMessages(xml));
        myProgressDialog.dismiss();
((LinearLayout)findViewById(R.id.LinearlayoutMessage)).addView(iiii);


      }

    }.start();

at the time of adding views to the layout i am getting the above error.what is the wrong in this.Please give me some suggestions.Thanks in advance

You can use Handlers as in this example(handleMessage runs on UI thread, so there you can modify views) or for more sophisticated things, use AsyncTask (onPostExecute runs also in UI thread)

That's how your code should look like using Handler:

private Handler myHandler = new Handler() {
    public void handleMessage(Message msg) {
        //in case you passed data to message (see below) here you can retrieve it
        myProgressDialog.dismiss();
        ((LinearLayout)findViewById(R.id.LinearlayoutMessage)).addView(iiii);
    }
};

private myProgressDialog = ProgressDialog.show(Shout.this,"","Loading...",true);

new Thread() {
    public void run() {
        String xml;
        xml="<spGetUserMessages><SearchLocation></SearchLocation></spGetUserMessages>";
        messages = parse.GetGetUserMessages(dataparsing.ILGetUserMessages(xml));
        Message msg = myHandler.obtainMessage();
        //here you can add data to the message using msg.obj, msg.what...
        //refer to http://developer.android.com/reference/android/os/Handler.html for details
        myHandler.sendMessage(msg);
   }
}.start();

Only the UI thread can modify views.

Use Activity.runOnUIThread(Runnable)
