Custom view that show text and wrapping content

Vote count:


I have a custom view that write text and I wish to know how to deal with height wrap content.


1) When to calculate the height of the text? In the OnMeasure?

2) What if the text height will be too large to fit in any view, in the onDraw() should I keep drawing the whole text lines? will that be inefficient to have lots of text be drawn though it wont appear any way?

3) Considering point 2 what if this custom view is put in a ScrollView? how efficient will that be? or should I handle scrolling manually in my view?
