How can I create an app that generates a random number in Android using Eclipse and then show the result in a
TextView field? The random number has to be in a range selected by the user. So, the user will input the max and min of the range, and then I will output the answer.
To extend what Rahul Gupta said:
You can use Java function
int random = Random.nextInt(n).
This returns a random
int in the range
I.e., to get the range
[20, 80] use:
final int random = new Random().nextInt(61) + 20; // [0, 60] + 20 => [20, 80]
To generalize more:
final int min = 20; final int max = 80; final int random = new Random().nextInt((max - min) + 1) + min;
