Maximize size of Android button text

Question

I had multiple buttons in a LinearLayout horizontally. On a larger device all the button text fit on one line at 20sp text size. However, on a smaller device at 20sp text size, the text of the buttons goes to two lines.

How can I tell it to make the text size as big as possible so that text stays on one line?

This works for me ... you will need to customize for your needs:

// Determine Scaled Density for later calculations
Display dd = ((Activity) m_Context).getWindowManager().getDefaultDisplay();
DisplayMetrics dm = new DisplayMetrics();
dd.getMetrics(dm);
float m_ScaledDensity = dm.scaledDensity;

Rect bounds = new Rect();
Paint p = new Paint();
p.setTypeface(btn.getTypeface());

// W is a very wide character
String sample = "NeedsToFIt"
int maxFont;
for (maxFont= 1
    ; -bounds.top <= btn.getHeight() && bounds.right <= btn.getWidth()
    ; maxFont++) {
  p.setTextSize(maxFont);
  p.getTextBounds(sample, 0, sample.length(), bounds);
}
maxFont = (int) ((maxFont - 1) / m_ScaledDensity);
btn.setTextSize(maxFont);
