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:

Answer 1

I made an asynctask class and did my getLineCount()-related tasks in its onPostExecute method.

protected void onCreate(final Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.main);

    new myAsyncTask().execute(null, null, null);
}

private class myAsyncTask extends AsyncTask {

    @Override
    protected Void doInBackground(final Void... params) {
        // It's okay to leave this as it is
        return null;
    }

    @Override
    protected void onPostExecute(final Void result) {
        super.onPostExecute(result);
        //DO YOUR TASK HERE, getLineCount(), etc.       
    }
}
