Methods:- getMultilineHeight (TextView As android.widget.TextView, Text As java.lang.CharSequence, multi As float) As int

This can be used to show dynamic text in a label.

Usage: getMultiLineHeight( TextView as android.widget.TextView , Text as CharSequence, multiplier as float)
Multiplier is Line Spacing Multiplier, where 1 is normal, 2 is double line spacing so on...

Label1.Text = "this is a long sentence, and we need to " _
& "know the height required in order To show it completely."
Label1.TextSize = 20
Activity.AddView(Label1, 10dip, 10dip, 200dip, 30dip)

Label1.Height = LineS.getMultilineHeight(Label1, Label1.Text, 1.5)
- getMultilineHeight (TextView As android.widget.TextView, Text As java.lang.CharSequence, multi As float) As int
