LoginAsync la = new LoginAsync();
la.execute(username, pass);

}

You can pass txtUser and Pass to invokeLogin();
so it look like invokeLogin(txtUser,Pass);
Then your invokeLogin method
public void invokeLogin(String username, String pass){
login(username,pass);
}

When you add new commnent, always add this comment at the beginning of your data. Then refresh you ListView
data.add(0, commnent);
listAdapter.notifyDataSetChanged();

You can you this before init new Adapter:
data.add(0, value);
This will add new value in the begin of your list.

Finally done, I have used this data.add(0,obj) instead of data.add(obj) on onClick Action.
void onClickCommentButton(){
data.add(0,obj);
listAdapter= new MyAdapter(this, data);
commentPageLvCommentsList.setAdapter(listAdapter);
listAdapter.notifyDataSetChanged();
}

You will be able to do by adding header at top. There should be methods with adapterView or list. I had done last year . It allows only one header item per list though I remember.

The JSON text will deliver a base64 encoded bitmap or jpg.
ArrayList<String> al3=new ArrayList<String>();
change that to:
ArrayList<Bitmap> al3=new ArrayList<Bitmap>();
And in the loop change:
al3.add(Dphoto);
to:
Bitmap bitmap = decodeBitmapFromBase64 (Dphoto);
al3.add(bitmap);
Remove:
Bitmap[] = (Bitmap[]) getBitmapFromURL(Dphoto2); // does not even compile!
You have to implement a function decodeBitmapFromBase64(). You can find code for it on this site.
Remove all Toast()s from doInBackground. They are not allowed there. Put them in onPostExecute instead.

save your image url in db (if they are in a same folder on your host choose a base url and save only image name)
after fetching your data , there are alot of library for display images such as :
