textView.getLineCount() returns 0 after setTextSize method

I'm trying to resize my textview to fit in 1 line.

while (titleText.getLineCount() > 1) {
    float scaledDensity = ManagerStorage.mainActivity.getResources().getDisplayMetrics().scaledDensity;
    titleText.setTextSize(titleText.getTextSize() / scaledDensity - 0.5f);
    Log.i("lines", "" + titleText.getLineCount());
    }

However, while loop executes only once. After setTextSize method, getLineCount will always return 0. While loop is executed with runOnUiThread on runnable that works after view is returned by onCreateView method.

Try this 

while (titleText.getLineCount() > 1) {
        float scaledDensity = ManagerStorage.mainActivity.getResources().getDisplayMetrics().scaledDensity;
        titleText.setTextSize(titleText.getTextSize() / scaledDensity - 0.5f);

        titleText.post(new Runnable() {
            @Override
            public void run() {
                int lineCount = titleText.getLineCount();
                Log.i("lines", "" + titleText.getLineCount());
                // Use lineCount here
            }
        });
    }
