I want to "scroll" my PDF-Viewer and Listview, together, but it does not work, I can only scroll my listView and the pdf-view separately

You have to use - android.support.v4.widget.NestedScrollView for scrolling . — Sanwal Singh, May 23 '18 at 08:51
You can use [**`NonscrollableListview`**](https://stackoverflow.com/a/24629341/8867002) . And use nestedscrollview instead of scrollview — Jyoti JK, May 23 '18 at 09:12

You can use android:isScrollContainer="true". It will indicate that the view is one of the set of scrollable containers in its window. For more read this https://developer.android.com/reference/android/view/View

Because list view has its own scroll view you can not add it inside another scroll view so you must use them isolated

You shouldn't put a ListView inside a ScrollView because the ListView class implements its own scrolling and it just doesn't receive gestures because they all are handled by the parent ScrollView. I strongly recommend you to simplify your layout somehow. For example you can add views you want to be scrolled to the ListView as headers or footers.
```
    UPDATE:

    Starting from API Level 21 (Lollipop) nested scroll containers are officially supported by Android SDK. There're a bunch
```
of methods in View and ViewGroup classes which provide this functionality. To make nested scrolling work on the Lollipop you have to enable it for a child scroll view by adding android:nestedScrollingEnabled="true" to its XML declaration or by explicitly calling setNestedScrollingEnabled(true).
```
    If you want to make nested scrolling work on pre-Lollipop devices, which you probably do, you have to use corresponding
```
utility classes from the Support library. First you have to replace you ScrollView with NestedScrollView. The latter implements both NestedScrollingParent and NestedScrollingChild so it can be used as a parent or a child scroll container.
```
    But ListView doesn't support nested scrolling, therefore you need to subclass it and implement NestedScrollingChild. Fortunately,
```
the Support library provides NestedScrollingChildHelper class, so you just have to create an instance of this class and call its methods from the corresponding methods of your view class.
