I have a ListView and each row contains a different User object.
A User has these different fields:
- List of things I like
- List of things I hate
- List of games I play
- Description of myself
Now, when I populate the ListView, I want to show different things that each user has filled out. So for example, one row might show 'things I like' filled out, while another might show the 'description of myself'.
I don't want to adjacent rows to be showing the same type of row. All this code will be inserted into my BaseAdapter's getView methood.
What would be the best logic in terms of pseudocode to achieve this?
// Creates arraylist of elements that are complete in profile
List<String> profileElements = new ArrayList<String>();
if (user.getGameOwned() != null && user.getGameOwned().size() > 2) {
profileElements.add(KEY_GAMES_PLAYED);
}
if (user.getAboutMe() != null && !user.getAboutMe().isEmpty()) {
profileElements.add(KEY_ABOUT_ME);
}
if (user.getIAm() != null && user.getIAm().length > 2) {
profileElements.add(KEY_I_AM);
}
if (profileElements.size() > 0) {
String randomElement = profileElements.get(new Random().nextInt(profileElements.size() - 1));
if (randomElement.equals(KEY_GAMES_PLAYED)) {
// do whatever here
}
else if (randomElement.equals(KEY_ABOUT_ME)) {
// do whatever
}
}

For example:
int ctr = 1; // your counter - try to declare it on the global level if(ctr<4){//your 4 types of list -display(ctr); //print the current ctr
ctr++;
}else{
display(ctr);
ctr = 1; //make the value to 1 for the next batch of loop
}
code:
display(int index){switch (index){
case 1:
//List of things I like
break;
case 2:
//List of things I hate
break;
case 3:
//List of games I play
break;
case 4:
//Description of myself
break;
default:
break;
}
}
You could also do random.nextInt(4) but it might have the same result each row.
