Calculate text size according to width of text area

by

This should be a simple solution:

public void correctWidth(TextView textView, int desiredWidth)
{
    Paint paint = new Paint();
    Rect bounds = new Rect();

    paint.setTypeface(textView.getTypeface());
    float textSize = textView.getTextSize();
    paint.setTextSize(textSize);
    String text = textView.getText().toString();
    paint.getTextBounds(text, 0, text.length(), bounds);

    while (bounds.width() > desiredWidth)
    {
        textSize--;
        paint.setTextSize(textSize);
        paint.getTextBounds(text, 0, text.length(), bounds);
    }

    textView.setTextSize(TypedValue.COMPLEX_UNIT_PX, textSize);
}
