Я хочу использовать CardView в своем проекте, но когда я запускаю свое приложение, я получаю следующую ошибку. Я использую Eclipse.
Error: Error inflating class and android.support.v7.widget.CardView
The graphical view of my xml file says 'The following classes could not be instantiated:
- android.support.v7.widget.CardView (Open Class, Show Error Log)
See the Error Log (Window > Show View) for more details.'
Пожалуйста, помогите.
Это макет для моего фрагмента, где я использовал CardView
<FrameLayout 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"
tools:context="com.example.log.MyContactsFragment" >
<!-- TODO: Update blank fragment layout -->
<android.support.v7.widget.CardView
xmlns:card_view="http://schemas.android.com/apk/res-auto"
android:id="@+id/cvContactDetails"
android:layout_width="match_parent"
android:layout_height="200dp"
android:layout_gravity="center"
android:background="?android:attr/selectableItemBackground"
android:clickable="false"
android:elevation="20dp" >
<TextView
android:id="@+id/tvContacts"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Contact Info" />
<Button
android:id="@+id/bDelete"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Delete" />
<Button
android:id="@+id/bExport"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Export to phone contacts" />
</android.support.v7.widget.CardView>
Это макет для моей деятельности.
