I’m looking for an optimal way to resize wrapping text in a TextView so that it will fit within its getHeight and getWidth bounds. I’m not simply looking for a way to wrap the text- I want to make sure it both wraps and is small enough to fit entirely on the screen.
I’ve seen a few cases on StackOverflow where auto resizing was needed, but they are either very special cases with hack solutions, have no solution, or involve re-drawing the TextView recursively until it is small enough (which is memory intense and forces the user to watch the text shrink step-by-step with every recursion).
But I’m sure somebody out there has found a good solution that doesn’t involve what I’m doing: writing several heavy routines that parse and measure the text, resize the text, and repeat until a suitably small size has been found.
What routines does TextView use to wrap the text? Couldn’t those be somehow used to predict whether text will be small enough?
tl;dr: is there a best-practice way to auto-resize a TextView to fit, wrapped, in its getHeight and getWidth bounds?
