I am trying to use the Android Quiz sample but and I want to put all of the contents into a card view. I used the example of a card view (Which works completely) from the Android Navigation Drawer Sample. When running my app, it crashes. Yet no bugs are shown in the code. What is causing this? Here is my code:
<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="wrap_content">
<android.support.v7.widget.CardView
android:layout_width="match_parent"
android:layout_height="wrap_content">
<ScrollView xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:paddingBottom="@dimen/activity_vertical_margin"
android:paddingLeft="@dimen/activity_horizontal_margin"

<LinearLayout android:id="@+id/container"

</LinearLayout>
</LinearLayout>
</ScrollView>
</android.support.v7.widget.CardView>
</FrameLayout>
For reference, here is the code of the Navigation Drawer Sample's card view:
<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="wrap_content">
<!-- The CardView needs to be wrapped to ensure spacing is applied correctly. -->
<android.support.v7.widget.CardView
style="@style/Widget.SampleDashboard.Card"
android:layout_width="match_parent"
android:layout_height="wrap_content">
<LinearLayout
style="@style/Widget.SampleDashboard.Item"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="vertical">
<TextView
android:id="@android:id/text1"
style="@style/Widget.SampleDashboard.Item.Title"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:text="Hello world" />
<TextView
android:id="@android:id/text2"
style="@style/Widget.SampleDashboard.Item.Description"
android:layout_width="match_parent"
android:layout_height="wrap_content" />
</LinearLayout>
</android.support.v7.widget.CardView>
</FrameLayout>
Here is the code that was posted on the blog for this:
<android.support.v7.widget.CardView
android:layout_width="match_parent"
android:layout_height="wrap_content">
<!-- Your card content -->
</android.support.v7.widget.CardView>
Any help would be appreciated. I am very new to android development.
Just adding an answer if you'd like to accept it. The issue was a ClassNotFoundException because the gradle dependency for CardView was not added.
