Hi all, On my activity, im getting some big data from web, and while getting this data i want to show the user a ProgressDialog with spinning wheel. That i can do only with putting this code into a thread, right ? the problem is that after im getting this data i need to insert it into my tableLayout as TableRows and it seems impossible to access the TableLayout from the thread. What can i do to show this progress dialog and to be able access the table layout from the thread ?? Is there any event that happens on the end of the thread ? My code fails for : _tableLayout.addView(_tableRowVar, new TableLayout.LayoutParams( LayoutParams.FILL_PARENT, LayoutParams.FILL_PARENT)); My full code is : final ProgressDialog dialog = ProgressDialog.show(MyActivity.this, "", "Getting data.\nPlease wait...",true); new Thread() { public void run() { try { TableLayout _tableLayout; _tableLayout = (TableLayout)MyActivity.this.findViewById(R.id.tableLayoutID); List<String> data = getDataFromWeb(); // Get the data and bind it into the table publishTableLayoutWithTableRows(_tableLayout, data ); } catch (Exception e) { new AlertDialog.Builder(MyActivity.this) .setMessage(e.getMessage()) .show(); } dialog.dismiss(); } }.start();
