Creating a random selection on a popup menu

Question

So currently I've got an activity that's to do with something called Ad-Libs, in which there is a blank space in a sentence and the user taps on it to open a popup menu to add a word into the space. Currently I have it set so that only 3 words are available and they're the same 3 words every time its pressed, however I was wondering if its possible to have those 3 words be randomly selected from a list per-say, or maybe an array-list. I'll include my code that I use for when the user taps on the empty space as well as the xml code for the popup menu, however be noted that it's basically just a simple pop up menu.

        beginningtext.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v){
            PopupMenu heroPop = new PopupMenu(AdventureActivity.this, beginningtext);
            heroPop.getMenuInflater().inflate(R.menu.heropop_menu, heroPop.getMenu());
            heroPop.setOnMenuItemClickListener(new PopupMenu.OnMenuItemClickListener() {
                public boolean onMenuItemClick(MenuItem item) {
                    Toast.makeText(AdventureActivity.this,"You Selected : " + item.getTitle(),Toast.LENGTH_SHORT).show();
                    beginningtext.setText(R.string.partyMembers);
                    beginningtext.append(item.getTitle());
                    return true;
                }
            });
            heroPop.show();//showing popup menu
        }
    });//closing the setOnClickListener method

And for the pop up menu xml

<menu xmlns:android="http://schemas.android.com/apk/res/android" >

<item
    android:id="@+id/one"
    android:title="@string/party1"/>

<item
    android:id="@+id/two"
    android:title="@string/party2"/>

<item
    android:id="@+id/three"
    android:title="@string/party3"/>

<item
    android:id="@+id/four"
    android:title="@string/party4"/>

</menu>

Any help with this is very much appreciated, thank you very much.

You could build an array with the things you want,

String[] array = {"thing1","thing2"};

Then randomly generate a number within the range of the array length

0 - array.length - 1;

Check out this question for how to generate a random number.

If you wanted you could at runtime fill an arraylist with string assets and do the above on that arraylist.

Just make sure your random number doesn't go outside the bounds of your array! – M. Hig Jul 11 '18 at 16:13
I'll give it a shot! Thanks! – Alex Wong Jul 11 '18 at 16:48
Although I do have a question, on how that would work with the popup menu xml? Would i just assign something from the Arraylist into the item? I'm honestly not the greatest at android so I'm not so sure how that would be done. – Alex Wong Jul 11 '18 at 16:50
I've never personally used the menu but you should be able to do something to the effect of `item.setText(*what ever*)`. If you had a function that randomly gave you a string back it could be `item.setText(randomString());` Just make sure each xml item is bound to an object in your view. – M. Hig Jul 11 '18 at 16:55
Hm, well alright. I'll give it a try and hopefully it'll work out, thanks for the advice. – Alex Wong Jul 11 '18 at 16:56
