TextView.setAllCaps() equivalent in API older than 14?

问题

TextView.setAllCaps() started as of API 14. What is its equivalent for older APIs (e.g. 13 and lowers)?

I cannot find such method on lower APIs. Is maybe setTransformationMethod() responsible for this on older APIs? If yes, how should I use it? TextView.setTransformationMethod(new TransformationMethod() {... is a bit confusing.

回答1:

Try this:

textView.setText(textToBeSet.toUpperCase());

回答2:

What about oldskool strtoupper()?

回答3:

Bottom line is that toUpperCase() is the solution. I can't object that. If you prefer doing the setAllCaps() with TransformationMethod, take a look at my answer.
