カスタムviewpagerのpagertitlestripについて

アンドロイドアプリの開発をしています。

viewpagerでpagertitlestripを使う場合、普通はxmlにて

<android.support.v4.view.ViewPager
android:id="@+id/pager"
android:layout_width="match_parent"
android:layout_height="match_parent">

    <android.support.v4.view.PagerTitleStrip
        android:id="@+id/pager_strip"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:layout_gravity="top"/></android.support.v4.view.ViewPager>

とviewpagerの中にpagertitlestripを入れて使用すると思います。
そして、この方法で今まで問題なく動いてきました。

今回、カスタムviewpagerを用いてレイアウトを作りたいと考えております。

public class MyViewPager extends ViewPager{
public MyViewPager(Context context){
super(context);
}

public MyViewPager(Context context, AttributeSet attrs){
super(context, attrs);
}

@Override
protected void onMeasure(int widthMeasureSpec, int heightMeasureSpec){
int height = 0;
for(int i=0; i<getChildCount(); i++){
View child = getChildAt(i);
child.measure(widthMeasureSpec, MeasureSpec.makeMeasureSpec(0, MeasureSpec.UNSPECIFIED));
int h = child.getMeasuredHeight();
if(h > height) height = h;
}
heightMeasureSpec = MeasureSpec.makeMeasureSpec(height, MeasureSpec.EXACTLY);
super.onMeasure(widthMeasureSpec, heightMeasureSpec);
}
}

というjavaファイルを作り、xmlに

<com.application.MyViewPager
android:id="@+id/pager"
android:layout_width="match_parent"
android:layout_height="wrap_content">
</com.hijiri.application.MyViewPager>

と、カスタムビューを挿入しました。

これだとしっかり動くのですが、

<com.application.MyViewPager
android:id="@+id/pager"
android:layout_width="match_parent"
android:layout_height="wrap_content">

<android.support.v4.view.PagerTitleStrip
android:id="@+id/pager_strip"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_gravity="top"/>
</com.application.MyViewPager>

と、カスタムviewpagerの中にpagertitlestripを入れると、当該ページの起動時にアプリが落ちてしまいます。

カスタムviewpagerを使用した場合、pagertitlestripはどのようにすれば使えるのでしょうか？

なお、アプリが落ちたときのエラーログは以下の通りです。
