Question

The first thing to say is im a beginner and now im developing my first “real” android apps(it will be on Google Play).
I already google a lot about this “Quiz” application for android and i cant get good information nor project examples about this one (most of the code/project examples is about a viewFlipper/TextSwitcher changing everytime you touch the screen –thats not what i want). I also tried to search in Stackoverflow and what i got is some downvoted question without a good/helping answer.

So there will be a quiz section in my app, and i will have 3 type of questions :

1. A question with a radiobutton answer
2. A question with a checkboxlist answer
3. A question with an edittext answer

There will be about 50 questions in my apps, so i have a plan to create 3 different layouts.

And these are my question’s :

1. Do you have any links/examples?please share(I already try to find on my own) 😀
2. What is the best way to do this?(Example : like using viewFlipper with layouts, or something else)
3. Is it possible to generate a 3 different types of question(3 layouts) using viewFlipper?how to do this?

Thank you 😀

Answer 1

You should create one master layout for question, with a TextView for statement, a container (like FrameLayout) for answer layout , and next , previous Button‘s. In the container you can place two Views, a ListView and an EditText for editable answers. Visibility of both as GONE.

Now, Once you got master layout visible, you can load each question in same layout. You will need to set text of statement view, if your question has options, you set ListView visibile, load data in it and set it to single/multiple choice. Else, if you question has an editable answer, you set EditText visible, (set ListView visibilty to gone).

This will be much more efficient than inflating separate layouts per question, Also ListView perfectly handles any number of options , can be single/multiple choice and allows to scroll to any option independent of screen size.

Layout Xml:

<?xml version="1.0" encoding="utf-8"?>

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
              android:layout_width="fill_parent"
              android:layout_height="fill_parent"
              android:orientation="vertical">
    <TextView android:id="@+id/question__Statement"
              android:layout_width="match_parent"
              android:layout_height="wrap_content"
            />
    <FrameLayout android:layout_width="match_parent"
                 android:layout_height="0dp"
                 android:layout_weight="1"
            >
        <ListView android:id="@+id/question__options"
                  android:layout_width="match_parent"
                  android:layout_height="match_parent"
                  android:visibility="gone"
                />
        <EditText android:id="@+id/question__text"
                  android:layout_width="match_parent"
                  android:layout_height="wrap_content"
                  android:visibility="gone"
                />
    </FrameLayout>
    <LinearLayout android:layout_width="match_parent"
                  android:layout_height="wrap_content"
            >
        <Button android:id="@+id/question__prev"
                android:layout_width="0dp"
                android:layout_height="wrap_content"
                android:layout_weight="1"
                android:layout_alignParentLeft="true"
                android:text="Previous"
                />
        <Button android:id="@+id/question__next"
                android:layout_width="0dp"
                android:layout_height="wrap_content"
                android:layout_weight="1"
                android:layout_alignParentRight="true"
                android:text="Next"
                />
    </LinearLayout>

</LinearLayout>
