How to adjust text font size to fit textview

Question

Is there any way in android to adjust the textsize in a textview to fit the space it occupies?

E.g. I\'m using a TableLayout and adding several Te

I wrote a short helper class that makes a textview fit within a certain width and adds ellipsize "..." at the end if the minimum textsize cannot be achieved.

Keep in mind that it only makes the text smaller until it fits or until the minimum text size is reached. To test with large sizes, set the textsize to a large number before calling the help method.

It takes Pixels, so if you are using values from dimen, you can call it like this:

---

float minTextSizePx = getResources().getDimensionPixelSize(R.dimen.min_text_size);
float maxTextWidthPx = getResources().getDimensionPixelSize(R.dimen.max_text_width);
WidgetUtils.fitText(textView, text, minTextSizePx, maxTextWidthPx);

This is the class I use:

---

public class WidgetUtils {

    public static void fitText(TextView textView, String text, float minTextSizePx, float maxWidthPx) {
        textView.setEllipsize(null);
        int size = (int)textView.getTextSize();
        while (true) {
            Rect bounds = new Rect();
            Paint textPaint = textView.getPaint();
            textPaint.getTextBounds(text, 0, text.length(), bounds);
            if(bounds.width() < maxWidthPx){
                break;
            }
            if (size <= minTextSizePx) {
                textView.setEllipsize(TextUtils.TruncateAt.END);
                break;
            }
            size -= 1;
            textView.setTextSize(TypedValue.COMPLEX_UNIT_PX, size);
        }
    }
}
