SwipeRefreshLayout not working with empty List

My app contains a SwipeRefreshLayout with a listView inside of it. The list receives data from a server. So when the data is fetched and the list is populated correctly the swipe to refresh works, but when the data is not passed to the list and is empty the SwipeRefresh doesn’t work. Why can’t I swipe when the listView is empty?
That‘s my layout:

Your listview and the swipe refresh layout is within a nested scroll view which means the height of child of the nested scroll view becomes wrap content (Relative layout in your case) automatically (It also might be showing you a lint warning to replace the match parent height of your relative layout to wrap content).
therefore when there's no data in your list, the height of the whole layout group becomes 0 and the place where you need to swipe to refresh has a height of 0 and you cant swipe within a layout of height zero.
To solve this you can take a linear layout above your nested scroll view with the height of match parent and put your swipe refresh layout over it.
Let me know if you need the example code.
EDIT
Okay! so this is a workaround I found to solve the issue. You can try this and please let me know if this solves your problem.
The Idea is to wrap everything a swipe refresh layout.

Add ScrollView after CollapsingToolBar not working

In my CountryActivityInfo.java I have a collapsing toolbar with both width and height set to match-parent so it can occupy the whole phone screen. When I scroll up the toolbar gets a fixed 200dp height.
Right now, it looks like this:
I want to display, in that white screen that appears when the toolbar is collapsed, a vertical scroll view with a text view inside. How can I do that? I've tried this way:
<android.support.design.widget.AppBarLayout
android:id="#+id/testeparainfo"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="?attr/actionBarDivider">
<android.support.design.widget.CollapsingToolbarLayout
android:id="#+id/backgroundcollapsedtoolbarinfo"
android:layout_width="match_parent"
android:layout_height="match_parent"
app:expandedTitleMarginEnd="64dp"
app:expandedTitleMarginStart="48dp"
app:layout_scrollFlags="exitUntilCollapsed|scroll">
<ImageView
android:id="#+id/imgCountryInfoFoto"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:scaleType="centerCrop" />
<ImageView
android:id="#+id/imgCountryInfoEscuro"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:adjustViewBounds="true"
android:background="#drawable/background_pais_info"
android:scaleType="centerInside" />
<android.support.v7.widget.Toolbar
android:id="#+id/toolbaridinfo"
android:layout_width="match_parent"
android:layout_height="200dp"
app:layout_collapseMode="pin"
app:popupTheme="#style/ThemeOverlay.AppCompat.Light">
</android.support.v7.widget.Toolbar>
<TextView
android:id="#+id/txtNomePaisInfo"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_gravity="bottom"
android:layout_marginStart="30dp"
android:layout_marginTop="520dp"
android:paddingBottom="10dp"
android:text="TextView"
android:textColor="#android:color/background_light"
android:textSize="35sp"
app:layout_anchor="#+id/testeparainfo"
app:layout_anchorGravity="left|bottom" />
</android.support.design.widget.CollapsingToolbarLayout>
</android.support.design.widget.AppBarLayout>
<ScrollView
android:layout_width="match_parent"
android:layout_gravity="bottom"
android:layout_height="wrap_content">
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="vertical" >
<TextView
android:id="#+id/txtInfoPais"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_alignParentBottom="true"
android:layout_alignStart="#+id/btnArrowBackWhite"
android:layout_marginBottom="111dp"
android:text="TextView"
android:textColor="#android:color/background_light"
android:textSize="15sp"
android:visibility="invisible"
app:layout_anchor="#+id/imgCountryInfoFoto"
app:layout_anchorGravity="bottom|center" />
</LinearLayout>
</ScrollView>
But, when I do this, the text view gets inside the collapsing toolbar and gets collapsed with the toolbar.
By the way, all the XML is wrapped up in a Coordinator Layout!!!

Change the root to CoordinatorLayout
<?xml version="1.0" encoding="utf-8"?>
<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:layout_width="match_parent"
android:layout_height="match_parent"
android:fitsSystemWindows="true">
<android.support.design.widget.AppBarLayout
android:id="#+id/app_bar"
android:layout_width="match_parent"
android:layout_height="#dimen/app_bar_height"
android:fitsSystemWindows="true"
android:theme="#style/AppTheme.AppBarOverlay">
<android.support.design.widget.CollapsingToolbarLayout
android:id="#+id/toolbar_layout"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:fitsSystemWindows="true"
app:contentScrim="?attr/colorPrimary"
app:layout_scrollFlags="scroll|exitUntilCollapsed">
<android.support.v7.widget.Toolbar
android:id="#+id/toolbar"
android:layout_width="match_parent"
android:layout_height="?attr/actionBarSize"
app:layout_collapseMode="pin"
app:popupTheme="#style/AppTheme.PopupOverlay" />
</android.support.design.widget.CollapsingToolbarLayout>
</android.support.design.widget.AppBarLayout>
<include layout="#layout/content_scrolling" />
</android.support.design.widget.CoordinatorLayout>
and then in content_scrolling.xml use NestedScrollView and app:layout_behavior="#string/appbar_scrolling_view_behavior" use this property for proper behaviour.
<android.support.v4.widget.NestedScrollView xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
xmlns:tools="http://schemas.android.com/tools"
app:layout_behavior="#string/appbar_scrolling_view_behavior">
...
</android.support.v4.widget.NestedScrollView>

Add app:layout_behavior="#string/appbar_scrolling_view_behavior" inside your ScrollView.

Replace this code
you have to add app:layout_behavior="#string/appbar_scrolling_view_behavior" in your ScrollView.
<ScrollView
android:layout_width="match_parent"
android:layout_gravity="bottom"
android:layout_height="wrap_content"
app:layout_behavior="#string/appbar_scrolling_view_behavior">
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="vertical" >
<TextView
android:id="#+id/txtInfoPais"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_alignParentBottom="true"
android:layout_alignStart="#+id/btnArrowBackWhite"
android:layout_marginBottom="111dp"
android:text="TextView"
android:textColor="#android:color/background_light"
android:textSize="15sp"
android:visibility="invisible"
app:layout_anchor="#+id/imgCountryInfoFoto"
app:layout_anchorGravity="bottom|center" />
</LinearLayout>
</ScrollView>

ViewPager in RelativeLayout consumes full Height (Tabs)

I am working with AndroidStudio 3.0 and I am creating a TabbedActivity with Fragments using Java.
For realizing the following design:
sketch
i sourrounded the ViewPager with a RelativeLayout in order to display a static content object (TextView) below the ViewPager. For this I am using the attribute
android:layout_below="#id/container"
Unfortunately, the TextView never gets shown.
By fuzzling around i realized, that when setting the
android:layout_height="100dp"
of the ViewPager to a fixed value it will be displayed.
As I am a beginner to Android I am unsure how to handle this issue. Is it not possible to use the layout_below attribute when working with ViewPagers? Or do i have to set a fixed value for them?
Is there another solution to achieve what i want - simply showing a static content below a 'TabControl'?
Here is my complete XML code:

Thank You very much!

Change this part of your code:
<RelativeLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="vertical"
app:layout_behavior="#string/appbar_scrolling_view_behavior">
<android.support.v4.view.ViewPager
android:id="#+id/container"
android:layout_width="match_parent"
android:layout_height="wrap_content"
app:layout_behavior="#string/appbar_scrolling_view_behavior" >
</android.support.v4.view.ViewPager>
<TextView
android:id="#+id/static_content"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:gravity="center"
android:text="This is the Textiew that is not shown!"
android:layout_below="#id/container"
/>
</RelativeLayout>
I would replace this with a vertical LinearLayout. This allows you to give some space to the TextView and then give the rest of the space to the ViewPager, which a RelativeLayout won't allow.
<LinearLayout

android:layout_width="match_parent"

android:id="#+id/container"
android:layout_width="match_parent"
android:layout_height="0dp"
android:layout_weight="1"
app:layout_behavior="#string/appbar_scrolling_view_behavior">
</android.support.v4.view.ViewPager>
<TextView
android:id="#+id/static_content"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:gravity="center"
android:text="This is the Textiew that is not shown!"/>
</LinearLayout>

Toolbar title is displaying out of place

I'm using Collapsing toolbar in coordinator layout to achieve the following result. However the problem is when the Collapsing toolbar collapses, the title of the toolbar doesn't show in it proper place for some reason. I couldn't figure out what might be causing this weird issue. How can I fix this?

Remove the android:fitsSystemWindows="true" and it will work!

The problem might be because in your activity, you forgot to put:
final Toolbar toolbar = findViewById(R.id.toolbar); //or whatever your toolbar id is
setSupportActionBar(toolbar);

java android : resize appbarlayout when hide a specific relativelayout

I have a bug in android development.
I would like resize the appbarlayout when I hide a relative layout Contained in it. but the height of appbarlayout is not reloaded and so I have a bar blue.
Here is the result obtained :
I hide this relative layout when my adapter is empty.
Do you have any idea how to remedy this?
