textview.getLineCount always 0 in android

Question

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.

I know this question is quite old, but in case anyone comes here looking for the actual answer:

holder.text2.setText(arr2[position]);
holder.text2.post(new Runnable() {
    @Override
    public void run() {
        int lineCnt = holder.text2.getLineCount();
        // Perform any actions you want based on the line count here.
    }
});
