Custom view that show text and wrapping content

Vote count:

0

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

Questions:

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?
