ListView in Fragment not covering full Parent

I have a ListView in a Fragment which isn't covering the whole Parent when the List isn't fully populated.
The Problem is the scrolling behaviour of the ListView, I can only browse in the small piece of window the ListView is initially loaded in.
(4 Entries or more do occupy the entire Parent, with less entries the problem happens)
Fragment:
<LinearLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
xmlns:android="http://schemas.android.com/apk/res/android"
>
<ListView
android:id="#+id/list"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:divider="#null"
/> </LinearLayout>
Main XML:
<android.support.design.widget.CoordinatorLayout
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
xmlns:tools="http://schemas.android.com/tools"
android:id="#+id/container"
android:layout_width="match_parent"
android:layout_height="match_parent"
>
<FrameLayout
android:id="#+id/frame_container"
android:layout_width="match_parent"
android:layout_height="match_parent"
app:layout_behavior="#string/appbar_scrolling_view_behavior"
/>
<android.support.design.widget.BottomNavigationView
android:id="#+id/navigation"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_gravity="bottom"
android:background="?android:attr/windowBackground"
app:itemBackground="#color/bgBottomNavigation"
app:itemIconTint="#android:color/white"
app:itemTextColor="#android:color/white"
app:menu="#menu/navigation" />
</android.support.design.widget.CoordinatorLayout>
The ListView gets populated via Volley + JSON with an Adapter for the ListView. Comment if you need the Code.
When I'm trying to put the ListViews height on "match_parent" the whole screen is occupied by the ListView, but it isn't scrollable anymore.
What can I do?
EDIT:
Coordinator Layout - This is the Code of the Frame Coordinator with the Bottom Navigation in it:
<android.support.design.widget.CoordinatorLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
xmlns:tools="http://schemas.android.com/tools"
android:id="#+id/container"
android:layout_width="match_parent"
android:layout_height="match_parent"
>
<FrameLayout
android:id="#+id/frame_container"
android:layout_width="match_parent"
android:layout_height="match_parent"
/>
<android.support.design.widget.BottomNavigationView
android:id="#+id/navigation"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_gravity="bottom"
android:background="?android:attr/windowBackground"
app:itemBackground="#color/bgBottomNavigation"
app:itemIconTint="#android:color/white"
app:itemTextColor="#android:color/white"
app:menu="#menu/navigation" />
</android.support.design.widget.CoordinatorLayout>

You could set a minimum height attribute to your listView and adjust to what suits you.
Eg. to set it to 20dp, add android:minHeight="20dp" to your listView attributes.
Best solution would be to wrap all the contents of the CoordinatorLayout inside a layout you can control yourself, like a ConstraintLayout. In that case you would align the FrameLayout (and the fragments it handles) between your other components and everything would be scrollable and clickable. A mock of this solution would be:
<CoordinatorLayout>
<ConstraintLayout height="match_parent">
<BottomNavigation bottomToBottomOf="parent" />
<FrameLayout height="0dp"
topToTopOf="parent"
bottomToTopOf="bottomNavigation" />
</ConstraintLayout>
</CoordinatorLayout>

unable to scroll the screen which has grid view and listview below it

I have the following xml which has Gridview and framelayout below it.
My requirement is if I scroll the screen upwards whole screen should scroll, but for me Only listview scrolls
Below is the xml file:
<?xml version="1.0" encoding="utf-8"?>
<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:background="#color/white"
android:focusableInTouchMode="true"
android:paddingBottom="#dimen/activity_vertical_margin">
<ScrollView
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_below="#+id/time_card_header"
android:id="#+id/scrollView">
<GridView
android:id="#+id/timecard_grid"
android:layout_width="match_parent"
android:layout_height="130dp"
android:layout_margin="3dp"
android:fitsSystemWindows="true"
android:gravity="center_horizontal"
android:horizontalSpacing="1dp"
android:numColumns="3"
android:stretchMode="columnWidth"
android:verticalSpacing="1dp" />
</ScrollView>
<FrameLayout
android:id="#+id/timecard_reports"
android:layout_width="match_parent"
android:layout_height="fill_parent"
android:background="#color/white"
android:layout_below="#+id/scrollView"/>
</RelativeLayout

Actually GridView and Listview have already scroll. No need to put the above widgets in scrollview. Firstly, remove the scrollview. I think you need the FrameLayout to be fixed at the bottom and show gridview above. For that first use FrameLayout in the linear layout with align_parentbottom true. after that please place the gridview above FrameLayout. That will fix the problem.

Just put linearlayout below scroll view and then gridview.
<scrollview>
<linearlayout >
<gridview />
</linearlayout >
</scrollview>
Sorry i am giving the ans from the mobile but the concept is same.

You can use RecyclerView with GridLayoutManager and set nestedScrollingEnabled of recyclerView to false.
and instead of ScrollView use NestedScrollView as parent of RecyclerView:
private void setUpRecyclerView(View view) {
recyclerView = view.findViewById(id.repliesList);
recyclerView.setNestedScrollingEnabled(false);
recyclerView.setLayoutManager(new GridLayoutManager(getActivity(),numberOfColumns));
}
and xml file:
<android.support.v4.widget.NestedScrollView
android:id="#+id/nestedScroll"
android:layout_width="match_parent"
android:layout_height="match_parent">
<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:background="#color/white"
android:focusableInTouchMode="true"
android:paddingBottom="#dimen/activity_vertical_margin">
<RecyclerView
android:id="#+id/timecard_grid"
android:layout_width="match_parent"
android:layout_height="130dp"
android:layout_margin="3dp"
android:fitsSystemWindows="true"
android:gravity="center_horizontal"
android:horizontalSpacing="1dp"
android:numColumns="3"
android:stretchMode="columnWidth"
android:verticalSpacing="1dp" />
<FrameLayout
android:id="#+id/timecard_reports"
android:layout_width="match_parent"
android:layout_height="fill_parent"
android:background="#color/white"
android:layout_below="#+id/scrollView"/>
</RelativeLayout
</android.support.v4.widget.NestedScrollView>

Can't scroll completely down in ViewPager with NestedScrollView in CollapsedToolBarLayout

I'm creating a fragment with a collapsing Toolbar Layout using a ViewPager. This is the XML for the Layout:
<?xml version="1.0" encoding="utf-8"?>
<android.support.design.widget.CoordinatorLayout

android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_gravity="bottom"
app:tabIndicatorColor="#android:color/white"
app:tabSelectedTextColor="#color/lightGreen"
app:tabTextColor="#color/grey"/>
</android.support.design.widget.CollapsingToolbarLayout>
</android.support.design.widget.AppBarLayout>
<io.brandie.brandie.custom.NoSwipeViewPager
android:id="#+id/htab_viewpager"
android:layout_width="match_parent"

app:layout_behavior="#string/appbar_scrolling_view_behavior"
android:layout_marginBottom="#dimen/spacing_giant"
android:background="#color/white"/>
</android.support.design.widget.CoordinatorLayout>
The viewPager is filled with fragments that use a gridview to display different cards, this is the xml for the Fragment of the first tab:
<?xml version="1.0" encoding="utf-8"?>
<android.support.v4.widget.NestedScrollView
android:id="#+id/NestedScroll"
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:fillViewport="true"
android:fitsSystemWindows="true"
android:layout_gravity="fill_vertical"
android:theme="#style/ThemeOverlay.AppCompat.Dark.ActionBar">
<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:id="#+id/all_campaigns_frame"
android:layout_width="match_parent"
android:layout_height="match_parent"
tools:context="io.brandie.brandie.fragments.AllCampaignsFragment">
<GridView xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/all_campaigns_grid"
android:descendantFocusability="blocksDescendants"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:numColumns="2"
android:verticalSpacing="10dp"
android:horizontalSpacing="10dp"
android:stretchMode="columnWidth"
android:gravity="center" />
</FrameLayout>
</android.support.v4.widget.NestedScrollView>
With this I can scroll down anywhere on the screen to make the toolbar collapse and the view-pager expand. The problem is, when the tool-bar is completely collapsed and only the tabs are showing, I can't scroll the viewPager anymore. Since it holds a gridView with a lot of items, it results in that I can't scroll through them all, since the scroll just "stops".
I want it to look like this
But instead, when the toolbar is collapsed, I can't scroll the viewPager down anymore. I can however scroll it up to reveal the toolbar again, that works without issues. I am using Android API 16, is that an issue?
How do I fix this very irritating problem?
EDIT:
If I remove the NestedScrollView from the fragment XML, the collapsed Toolbar only collapses if I scroll on the toolbar. If I scroll the ViewPager, I can scroll through all content correctly, but the toolbar doesn't collapse.

Answer for your EDIT: Try using setNestedScrollingEnabled(false) on your GridView

I have 2 RecyclerViews in a Fragment. But only the 1st one is shown

I'm trying to have two RecyclerViews in a Fragment. One of them being a horizontally aligned RecyclerView, and the other a vertically aligned one. But only the horizontal RecyclerView is visible. (The vertical RecyclerView is visible if I change the order of the RecyclerViews in the layout file, so I'm pretty sure there's nothing wrong with the RecyclerViews.)
As per other answers to similar questions, I've added the layout_weight=1 in both the RecyclerViews. But the 2nd RecyclerView still doesn't show.
Here's my layout file:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical">
<android.support.v4.widget.SwipeRefreshLayout
android:id="#+id/swipeRefreshLayout"
android:layout_width="match_parent"
android:layout_height="match_parent">
<android.support.v7.widget.RecyclerView
android:id="#+id/CategoryPageRecyclerView"
android:layout_width="fill_parent"
android:layout_weight="1"
android:layout_height="0dp"
android:scrollbars="none" />
<android.support.v7.widget.RecyclerView
android:id="#+id/ItemsRecyclerView"
android:layout_width="fill_parent"
android:layout_weight="1"
android:layout_height="0dp"
android:scrollbars="vertical" />
</android.support.v4.widget.SwipeRefreshLayout>
</LinearLayout>
I have a feeling the SwipeRefreshLayout is causing an issue. Any ideas on how to fix this?

SwipeRefreshView supports only one direct child - wrap RecyclerViews in LinearLayout and it will work.
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical">
<android.support.v4.widget.SwipeRefreshLayout
android:id="#+id/swipeRefreshLayout"
android:layout_width="match_parent"
android:layout_height="match_parent">
<LinearLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical" />
<android.support.v7.widget.RecyclerView
android:id="#+id/CategoryPageRecyclerView"
android:layout_width="fill_parent"
android:layout_weight="1"
android:layout_height="0dp"
android:scrollbars="none" />
<android.support.v7.widget.RecyclerView
android:id="#+id/ItemsRecyclerView"
android:layout_width="fill_parent"
android:layout_weight="1"
android:layout_height="0dp"
android:scrollbars="vertical" />
</LinearLayout>
</android.support.v4.widget.SwipeRefreshLayout>
</LinearLayout>

ScrollView not scrolling far enough - java Android Studio

I am working on a app where the user actions add LinearLayout's to the pre-existing LinearLayout #+id/linLayout. Sometimes these additional layouts will go off the bottom of the screen so I have put the main LinearLayout within a ScrollView. When my app starts to go off the bottom of the screen it is able to scroll a little bit but not far enough to see everything. At a certain point it is not possible to continue because a Button is off screen and cannot be pressed. Can anybody tell me what I'm doing wrong?
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_marginStart="#dimen/activity_horizontal_margin"
app:layout_behavior="#string/appbar_scrolling_view_behavior"
tools:showIn="#layout/activity_main"
tools:context=".MainActivity">
<LinearLayout 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:orientation="vertical" >
<Button android:id="#+id/bGenerateExample"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="#string/generate_example" />
<ScrollView
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="wrap_content">
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:id="#+id/linLayout"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:orientation="vertical" >
</LinearLayout>
</ScrollView>
</LinearLayout>
</RelativeLayout>

What about using weight_Sum?
<LinearLayout 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:orientation="vertical"
android_weight_sum=5 >
<Button android:id="#+id/bGenerateExample"
android:layout_width="match_parent"
android:layout_height="0dp"
android:layout_weight="1"
android:text="#string/generate_example" />
<ScrollView
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="0dp"
android:layout_weight="4">
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:id="#+id/linLayout"
android:layout_width="match_parent"
android:layout_height="marth_parent"
android:orientation="vertical" >
</LinearLayout>
</ScrollView>
</LinearLayout>
now button covers %20 percent of screen and scrollView covers %80.You can change it easily with changing layout_weight values of scrollView, Button.
