MeasureMultilineTextHeight doesn't work with line spacing?

[susu]

Hi all,

I used this code to change the space between text lines of Label.

   Dim Obj1 As Reflector
   Obj1.Target = label1
   Obj1.RunMethod3("setLineSpacing", 1, "java.lang.float", 1.3, "java.lang.float")

and MeasureMultilineTextHeight always return wrong height (shorter). Anyone can help? Thank you.

MeasureMultilineTextHeight assumes that the default values are used.

So there's no way to solve it?

Susu,
Have you tried adjusting the MeasureMultilineTextHeight by the proportions that you have adjusted the line spacing by?
Might just be a simple solution?

Not with this method. Here is the code:

   public int MeasureMultilineTextHeight(TextView TextView, String Text) {
      StaticLayout sl = new StaticLayout(Text, TextView.getPaint(), 
            TextView.getLayoutParams().width - TextView.getPaddingLeft() - TextView.getPaddingRight(),
            Alignment.ALIGN_NORMAL, 1, 0 , true);
      return sl.getLineTop(sl.getLineCount());
   }

You can create a small library that allows you to set the mult and add values instead of 1 and 0.

Are you kidding? If I know how to create a library, I didn't ask you that question

However, I solved it by my way:

' MeasureLabel : Fake label to measure the height of text. Set it visible = False
' txt : String that contain the text.
' RLabel : This label you really want to display

            rowheight = su.MeasureMultilineTextHeight(MeasureLabel, txt) 
            Obj1.Target = RLabel 
            before = Obj1.RunMethod("getLineHeight")    'Get the height of line BEFORE you change it
            Obj1.Target = RLabel 
            Obj1.RunMethod3("setLineSpacing", 0, "java.lang.float", 1.5, "java.lang.float")  'Change the space between lines
            Obj1.Target = RLabel 
            after = Obj1.RunMethod("getLineHeight")    'Get the height of line AFTER  you change it
            finalheight = ((after * rowheight)/before) + 20dip   'Add 20dip to have some space below the text.

This way maybe not the best but at least it worked for me.
