use this way:

in Activity:

import android.os.Bundle;

import com.actionbarsherlock.app.ActionBar;
import com.actionbarsherlock.app.SherlockPreferenceActivity;

public class MainActivity extends SherlockPreferenceActivity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        // setContentView(R.layout.custom_infowindow);
        final ActionBar actionBar = getSupportActionBar();
        actionBar.setCustomView(R.layout.custom_infowindow);
        actionBar.setDisplayShowTitleEnabled(false);
        actionBar.setDisplayShowCustomEnabled(true);
        actionBar.setDisplayUseLogoEnabled(false);
        actionBar.setDisplayShowHomeEnabled(false);

        addPreferencesFromResource(R.xml.test);
    }

}

custom_infowindow.xml

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:gravity="center"
    android:orientation="vertical" >

    <TextView
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="Right Now Event"
        android:textAppearance="?android:attr/textAppearanceLarge"
        android:textColor="#FF0000" />

    <View
        android:layout_width="match_parent"
        android:layout_height="5dp"
        android:background="@color/_blue" />

</LinearLayout>
