NestedScrollView height is not match_parent

Question

I use https://github.com/nhaarman/ListViewAnimations to implement the drag&drop, swipe to delete etc. But there are problems the first image can scroll the list but cannot drag&drop (it drop to the same location and it don't enter the onItemMoved)

The second image I remove the linearLayout. Now I can scroll and drag&drop but the layout is broken.

I think I will measure the whole screen height the directly fix the height of NestedScrollView. But I think it may not a best practice for this problem. My question was is there a better way to fix my problems?

The third image I remove the linearLayout and NestedScrollView so user cannot scroll the list.

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
          xmlns:app="http://schemas.android.com/apk/res-auto"
          android:id="@+id/drawerLayout"
          android:orientation="vertical"
          android:layout_width="match_parent"
          android:layout_height="match_parent">

This is my current solution. I think there is a better solution.

The actionBar height from this topic

public static float getListHeight (Activity activity) {
    DisplayMetrics displayMetrics = getScreenSize (activity);
    float height = displayMetrics.heightPixels;
    float density = activity.getResources ().getDisplayMetrics ().density;
    float headerHeight = activity.getResources ().getDimension (R.dimen.landing_header_max_height) / density;
    float screenHeight = height / density;
    int actonBarHeight = (int) (getActionBarHeight (activity) / density);
    //Log.d ( "Utility", "ScreenHeight" + screenHeight + "headerHeight=" + headerHeight +"dense="+density+"actionBarHeight"+actonBarHeight);
    return ( screenHeight - headerHeight )*density-actonBarHeight;
}

public static int getActionBarHeight(Activity activity){
    TypedValue tv = new TypedValue();
    if (activity.getTheme().resolveAttribute(android.R.attr.actionBarSize, tv, true)) {
        return  TypedValue.complexToDimensionPixelSize(tv.data,activity.getResources().getDisplayMetrics());
    }
    return -1;
}

public static DisplayMetrics getScreenSize (Activity activity) {
    Display display = activity.getWindowManager ().getDefaultDisplay ();
    DisplayMetrics outMetrics = new DisplayMetrics ();
    display.getMetrics (outMetrics);

    return outMetrics;
}
