Changing line height of a Label

I want to increase the line height or the spacing between each line of text inside a label. I checked B4A and couldn't find any methods to accomplish this.

So next I checked the official Android documentation of TextView and found something called setLineSpacing

public void setLineSpacing (float add, float mult)

Sets line spacing for this TextView. Each line will have its height multiplied by mult and have add added to it.

Click to expand...

I then tried to set this value using Reflection library


When executing, I get NoSuchMethodException. What could be wrong?
