how to move from question to question for a quiz app

Essentially what I will be writing is a quiz type开发者_运维问答 application. Basically there will be a paragraph or so to read, with one or more choices below. There will be several criteria to decide what the next question will be, ie. If it was a hard question and get it wrong, the next is easier, or maybe less choices, etc.

Where would I put the logic to determine what the next question would be? Also, once I have what the next question would be, how do I update both the text part, as well as the new choices?

You generate TextViews on the go, and replace them after storing the result of the previous question.

You need to use Item Response Theory.
