    //Cursor cur1 = getContentResolver().query(uriSMSURI1, null, null, null,null);
    while (cur.moveToNext()) {
        int type = cur.getColumnIndex("type");
        String address = cur.getString(cur.getColumnIndex("address"));
        long  millis = cur.getLong(cur.getColumnIndexOrThrow("date"));
        String dat = (String) DateFormat.format("EEEE, MMMM dd, yyyy h:mm:ss aa", new Date(millis));
        String body = cur.getString(cur.getColumnIndexOrThrow("body"));

Which Adapter are you using? If you are using CursorAdapter, then you can do it in your bindView(). Here is a rough example code:

TextView tv = null; 

@Override
public View newView(Context context, Cursor cursor, ViewGroup parent) {
      tv = (TextView) v.findViewById(R.id.itemname);
}

@Override
public void bindView(View view, final Context context, final Cursor cursor) {

  if(condition1){
     tv.setBackgroundResource(R.color.white);
  }else{
     tv.setBackgroundResource(R.color.black);
  }

}

If you are using any other Adapter, you can use the corresponding methods to apply the same logic.
