Android CalendarView class cannot be found

Question

Im designing the xml format for a calendar to be used in an app, but I cant get the calendar to show in the graphical layout shower.

Instead I get the following 'error':

The following classes could not be found: - CalendarView (Change to android.widget.CalendarView, Fix Build Path, Edit XML)

The min SDK version for this project is 14 and its target version is 15.

Here is my XML code:

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"     android:layout_width="fill_parent"     android:layout_height="fill_parent"     android:orientation="horizontal" >          <RelativeLayout android:id="@+id/top"             android:layout_width="fill_parent"             android:layout_height="wrap_content">                 <Button android:id="@+id/dash"                     android:layout_height="wrap_content"                     android:layout_width="wrap_content"                     android:maxWidth="200dp"                     android:maxHeight="10dp"                     android:text="DASHBOARD"                     android:textAppearance="?android:attr/textAppearanceSmall"                     android:layout_alignParentLeft="true"/>                  <TextView                     android:id="@+id/textView1"                     android:layout_width="wrap_content"                     android:layout_height="wrap_content"                     android:layout_centerInParent="true"                     android:paddingBottom="10px"                     android:paddingTop="10px"                     android:text="Calendar"                     android:textAppearance="?android:attr/textAppearanceLarge"/>                 <Button                     android:id="@+id/plusButton"                     style="?android:attr/buttonStyleSmall"                     android:layout_width="wrap_content"                     android:layout_height="wrap_content"                     android:layout_alignParentRight="true"                     android:text="+"                     android:textAppearance="?android:attr/textAppearanceLarge"/>         </RelativeLayout>         <CalendarView             android:id="@+id/calview"             android:layout_width="fill_parent"             android:layout_height="wrap_content"             android:layout_below="@+id/top"             android:maxHeight="300dp" />          <RelativeLayout android:id="@+id/infoScroll"             android:layout_width="fill_parent"             android:layout_height="wrap_content"             android:layout_below="@+id/calview">              <ScrollView                 android:id="@+id/scrollView1"                 android:layout_width="fill_parent"                 android:layout_height="wrap_content"                 android:maxHeight="100dp">                  <ListView                     android:id="@+id/listView1"                     android:layout_width="match_parent"                     android:layout_height="match_parent" >                 </ListView>              </ScrollView>         </RelativeLayout>         <RelativeLayout android:id="@+id/bottomBar"             android:layout_width="fill_parent"             android:layout_height="wrap_content"             android:layout_below="@+id/infoScroll">             <Button android:id="@+id/todayButton"                 android:layout_height="wrap_content"                     android:layout_width="wrap_content"                     android:layout_alignParentLeft="true"                     android:text="Today"                 android:textAppearance="?android:attr/textAppearanceSmall"/>              <Button android:id="@+id/listButton"                 android:layout_height="wrap_content"                     android:layout_width="wrap_content"                     android:layout_toLeftOf="@+id/dayButton"                     android:text="List"                     android:textAppearance="?android:attr/textAppearanceSmall"/>          <Button android:id="@+id/dayButton"                 android:layout_height="wrap_content"                     android:layout_width="wrap_content"                     android:layout_centerInParent="true"                     android:text="Day"                 android:textAppearance="?android:attr/textAppearanceSmall"/>          <Button             android:id="@+id/monthButton"             android:layout_width="wrap_content"             android:layout_height="wrap_content"             android:layout_toRightOf="@+id/dayButton"             android:text="Month"             android:textAppearance="?android:attr/textAppearanceSmall"/>          <Button android:id="@+id/PeopleButton"             android:layout_height="wrap_content"                 android:layout_width="wrap_content"                     android:layout_alignParentRight="true"                 android:text="People"                 android:textAppearance="?android:attr/textAppearanceSmall"/>            </RelativeLayout>  </RelativeLayout> 

Much appreciated! Thanks!

Answer 1

you might be previewing your screen on Android Target 16. Try using Android Target 15 for Graphic Layout Editor (android icon on the top, in ADT 20). Looks like there is issue with Android Target 16.

NOTE: You don't need to set the project target just the target in the graphical layout editor.
