QUESTION
I made a multiple choice game and tried to randomize the questions by using the shuffle method on my array which contains all my questions. The problem is that some questions are being constantly repeated, so you will see some questions two times, some you won't see at all. I thought that I could use a arraylist instead of an array, so I could use the remove method after a question has been asked, but I Always get Errors with the arraylist and I don't even know if my approach makes sense. You can see my problem under that big chunk full of objects, in the ShuffleQuestions method and the ShowNextQuestion method.
How would you go on about this problem? Thank you for your help!
Here's my Code:
...ANSWER
Answered 2020-Feb-02 at 21:34You shuffle the question every time; that's the wrong way to go about it.
Shuffle ONCE only, then maintain a pointer into the structure; it starts at 0 and everytime you render a question, up it. This way, you walk through the entire array of questions precisely once, hitting every question exactly once, and the one-time sorting ensures that it'll be a uniform different order every time you go through.
QUESTION
I have Admob Banner adds in my Recycler listview, but the ad is overlaying the list item. I have been through the stack looking for a way to fix this, the closest I have come is Embedding ads within Recyclerview
I have tried several of the answers provide in this article without any success. The banner add always overlays the list item. As you can see from the image below there are five games and Game 4 should be showing below the Banner Ad.
Can someone please help me fix this issue. I have placed the code for my Adapter below.
...ANSWER
Answered 2019-Aug-06 at 13:39When passing a List of objects to a recycler view it expect a single model (a single object type). In your case you are passing a Game object.
Say you have a list with 5 objects (as your example shows).. When building your holder you are replacing the fourth object with an AD_VIEW instead of building a holder for the fourth object.
Solution 1: Add an AdView to your layout with visibility=GONE Set visibility to VISIBLE when you your position variable meets the requirements.
Solution 2: Create a wrapper object that looks somthing like this:
QUESTION
I am trying to create an app which uses a SQL database via room and LiveData. It's a very very simple Quiz App. There will be a question and couple of possible answers displayed. Additionally there is a next and previous button to navigate through the questions.
There are two tables: "table_question" and "table_answer".
table_question consists of following columns: id, question
table_answer: id, answer, id_question
id_question allocates the answers to the questions because it is a 1:n relationship.
I get a list of all questions and all answers from the database as a LiveData object. On the other hand I would like to have a LiveData class QuizWorld which handles all the data necessary to be displayed on the screen (questions answered, right answered, wrongly answered, questions left and so on). This class will be observed by the Activity so the UI can be updated.
But how do I close the gap between the two LiveData Lists "questions" and "answers" and the creation of the LiveData QuizWorld? QuizWorld will need those information saved in questions and answers but a LiveData object doesn't have a constructor.
I had the idea of using Transformations.switchMap but I couldn't make it work. Even if I forget the QuizWorld class and do everything within ViewModel leaves me with the Problem that I cannot access the LiveData Lists.
Note: It is actually not necessary that the Lists are LiveData objects because the SQL database doesn't change during runtime. I just had no other idea how to access the database via room. But it would still be a nice feature to have if in future the database becomes more dynamically which is not planned yet.
Here is a part of the code:

Answered 2019-Apr-05 at 08:15I am not completely sure about what you want exactly, but I would rather suggest you to have an object QuestionWithAnswer containing one question and its answers instead of two different lists. Then you could make a query in the dao class who would return that QuestionWithAnswer class (or a list of these objects in your case)
See this link for querying multiple tables (the sample with user and pet should look like yours) In the Dao class, you would have something like :

I do not understand what do I miss in my prepareQuestion method. MainActivity starts but my RecycleView is empty. In the beginning In MainActivity I had question and radio buttons, when time ran out or "Confirm/Next" button is pressed next question and choices were loading. I decided to try to use RecycleView and Cards to load all question at once in MainActivity.
public class MainActivity extends AppCompatActivity {

QUESTION
This is an edit from my original question as I have changed the way I want to display the scores.
Previously, my score from the GameActivity class would pass to the MainMenu activity class no problem. My issue was that I wanted to display a high score as well which would change if a user beat the previous best.
I've changed my mind now in that I will display the users current score in the game activity when the game has ended and when they click back to the MainMenu class/screen, only the highest score shows. So, I've changed the code slightly so that only Highest Score is shown but this is just showing the score from the previous game whether it's a higher score or not.
I need to know how to make it so that it only passes the score to the MainMenu activity if it beats the previous one.
My GameActivity class is below:
...ANSWER
Answered 2017-Apr-25 at 00:37For you the best and easiest way to store highest value would be shared preferences. They are the key value pairs persistent throughout the activity of your app and even after.

QUESTION
Hopefully I can get some advice on this.
My program has a sprite that, when hit/clicked, a score is tallied on screen. When the game is over (time runs out), I want the user to be able to press the back key on their phone to go back to the main/start screen/activity where they began the game, but it will also show their score (how many hits).
I'm struggling to figure out how to get it to go back with the back key press. I can figure out the high score bit at a later date if need be. I just want to get back to that start screen.
UPDATE:
I think it may have something to do with my manifest as to why it's not working. I've tried to add the 'GameView' class to the manifest but it won't accept it. It says it has no default constructor. Any ideas?
