textview.getLineCount always 0 in android

Question

Hi all,

I'm trying to dynamically resize my textview but getlinecount() method always returns me 0 even after settext() and invalidate(). I'm using the following code:

        if(convertView == null){
            convertView = lInflater.inflate(R.layout.listview, null);
            holder = new ViewHolder();
            holder.text2 = (TextView)convertView.findViewById(R.id.TextView02);
        convertView.setTag(holder);
        }

        else{
            holder = (ViewHolder)convertView.getTag();
        }

        holder.text2.setText(arr2[position]);
        holder.text2.invalidate();
        int lineCnt = holder.text2.getLineCount();

holder is a static class as follows:

    static class ViewHolder{
        TextView text2;
} 

holder contains non null text2 and the content set is also non null.

Can anybody please help?

Thanx in advance.

getLineCount() will give you the correct number of lines only after a layout pass. That means the TextView must have been drawn at least once. I assume that at this point of time your Textview is not drawn hence you are getting 0 as the line count
