I Have activity that get some data from the internet, and shows it to the screen. I m using scroll view cause it s long text, I also want different text style for a different data,so I use few textViews with a different style and to show it on the Activity screen, my problem is that scroll view can handle only one view, so how can I use scrolling to show different style of Text view, I tried to add LinearLayout to the scrollView and add all the textViews dynamically in code to this LinearLayout ,but I m getting exception - scroll view can host only one direct child.

守则如下:

/** this is the function, which called from the onClick method.
wanted data object contains 2 strings title message and the message itself.

When debug the code i can see that there s two String values in each loop.
but i cant add the linearLayout to my scrollView - exception ScrollView can host only one direct child */

    private void showResult(ArrayList<WantedData> result) {
        // TODO Auto-generated method stub
        TextView title;
        TextView data;
        scrollLayout = (LinearLayout) findViewById(R.id.LlScrollView);  
        for (WantedData curr : result) {
            if (curr.getTitle() == null) {
                break;
            }

            title = new TextView(this);
            title.setText(curr.getTitle());

            scrollLayout.addView(title, LayoutParams.FILL_PARENT,
                    LayoutParams.WRAP_CONTENT);
            data = new TextView(this);
            data.setText(curr.getData());   
            scrollLayout.addView(data, LayoutParams.FILL_PARENT, LayoutParams.WRAP_CONTENT);
        }
        scroll.addView(scrollLayout, LayoutParams.FILL_PARENT, LayoutParams.WRAP_CONTENT);

        //at the onCreate method -  scroll = (ScrollView) findViewById(R.id.SvShowTextFromServer);
    }
