Error inflating class android.support.v7.internal.widget.ActionBarView

Question

My application was working but when I came to start working on it this morning everything is not working. I am getting an error inflating class error which seems to be from an xml file where I get the "Binary XML file line #25" line. As I said this was working fine and now all of a sudden it does not. Below is the exception trace:

Here is the XML file it bombs on in my class at setContentView(R.layout.activity_tabbed), as this is the line where everything bombs out.

activity_tabbed.xml:

<RelativeLayout 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"
    android:paddingRight="@dimen/activity_horizontal_margin"
    android:paddingTop="@dimen/activity_vertical_margin"
    tools:context=".TabbedActivity" >


    <view class="com.ypmmllc.dailychecklist.CustomViewPager"
        android:id="@+id/pager"
        android:layout_width="match_parent"
        android:layout_height="match_parent">
    </view>
</RelativeLayout>

And now the CustomViewPager class that I am referencing within the XML file:

package com.ypmmllc.dailychecklist;

import android.content.Context;
import android.support.v4.view.ViewPager;
import android.util.AttributeSet;
import android.view.MotionEvent;

public class CustomViewPager extends ViewPager {

    private boolean enabled;

    public CustomViewPager(Context context, AttributeSet attrs) {
        super(context, attrs);
        this.enabled = false;
    }

    public CustomViewPager(Context context)
    {
        super(context);
        this.enabled = false;
    }

    @Override
    public boolean onTouchEvent(MotionEvent event) {
        if (this.enabled) {
            return super.onTouchEvent(event);
        }

        return false;
    }

    @Override
    public boolean onInterceptTouchEvent(MotionEvent event) {
        if (this.enabled) {
            return super.onInterceptTouchEvent(event);
        }

        return false;
    }

    public void setPagingEnabled(boolean enabled) {
        this.enabled = enabled;
    }
}

Answer 1

Try to clean up the project and rebuild it:

IntelliJ IDEA: Build -> Rebuild project; Eclipse: Project -> Clean

Answer 2

Try this:

<com.ypmmllc.dailychecklist.CustomViewPager
    android:id="@+id/pager"
    android:layout_width="match_parent"
    android:layout_height="match_parent" />
