Although this is terrible, I’ll still show a possible way to do this. But just remember, this is TERRIBLE<\/strong>.<\/p>\n

You can store all the activity classes in an ArrayList<\/code>.<\/p>\n

ArrayList<Class<Activity>> activities = new ArrayList<> ();\n<\/code><\/pre>\n
And then you add all the activities into the ArrayList<\/code>. Yeah, I know, this part is tedious. For example,<\/p>\n
 activities.add (Activity1.class);\n<\/code><\/pre>\n
And then you create a Random<\/code> called rand<\/code> and use that to access an element in the list:<\/p>\n
list.get (rand.nextInt (list.size()));\n<\/code><\/pre>\n
\n
Here is another “better” way to do it, but it’s still kinda bad. I strongly advise you to store teh questions in a database. Anyway, here’s the better-but-still-bad method.<\/p>\n
You create a question class:<\/p>\n
public class Question  {\n    \/\/here you can put correctAnswer, questionText etc\n}\n<\/code><\/pre>\n
After that, you make an ArrayList<\/code> of Question<\/code>s i.e. ArrayList<Question><\/code>.<\/p>\n
ArrayList<Question> questions = new ArrayList<> ();\n<\/code><\/pre>\n
And still, you need to add 1000 questions to the array list. Then you can just use a Random<\/code> to access it.<\/p>\n
When you want to display a question in one<\/em> activity, you can just putExtra<\/code> in Intent<\/code> before starting the activity. putExtra<\/code> basically passes some “parameter” thingys to the activity. Then in the activity, you can just get the “Extra” and use the Question<\/code> object to display. e.g. set the text of a TextView<\/code> to the question text.<\/p>\n<\/p><\/div>\n
