No release momentum inside ScrollView - android

In my activity, I have two RecyclerViews inside a ScrollView. The problem is that when I swipe/flick the ScrollView, scrolling stops immediately. Is there a way to get the ScrollView to implement momentum or inertia so there's some deceleration before the scrolling stops?
My XML is below:
<?xml version="1.0" encoding="utf-8"?>
<FrameLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent">
<ProgressBar
android:id="#+id/threadload_progress"
style="?android:attr/progressBarStyleLarge"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_marginBottom="8dp"
android:visibility="gone" />
<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"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:orientation="vertical">
<android.support.v7.widget.RecyclerView 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/subforums"
android:name="net.polunom.forum.fragments.ThreadFragment"
android:layout_width="match_parent"
android:layout_height="wrap_content"
app:layoutManager="LinearLayoutManager"
tools:context=".fragments.ThreadFragment"
tools:listitem="#layout/fragment_subforum"/>
<android.support.v7.widget.RecyclerView 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/threadlist"
android:name="net.polunom.forum.fragments.ThreadFragment"
android:layout_width="match_parent"
android:layout_height="wrap_content"
app:layoutManager="LinearLayoutManager"
tools:context=".fragments.ThreadFragment"
tools:listitem="#layout/fragment_thread"/>
</LinearLayout>
</ScrollView>

I figured it out! All I had to do was set setNestedScrollingEnabled(false); to the two RecyclerViews, and everything started working like a charm.

You can disable nested scrolling directly in your XML with: android:nestedScrollingEnabled="false"
So your XML would look like:
<?xml version="1.0" encoding="utf-8"?>
<FrameLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent">
<ProgressBar
android:id="#+id/threadload_progress"
style="?android:attr/progressBarStyleLarge"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_marginBottom="8dp"
android:visibility="gone" />
<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"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:orientation="vertical">
<android.support.v7.widget.RecyclerView 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/subforums"
android:nestedScrollingEnabled="false"
android:name="net.polunom.forum.fragments.ThreadFragment"
android:layout_width="match_parent"
android:layout_height="wrap_content"
app:layoutManager="LinearLayoutManager"
tools:context=".fragments.ThreadFragment"
tools:listitem="#layout/fragment_subforum"/>
<android.support.v7.widget.RecyclerView 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/threadlist"
android:nestedScrollingEnabled="false"
android:name="net.polunom.forum.fragments.ThreadFragment"
android:layout_width="match_parent"
android:layout_height="wrap_content"

</LinearLayout>

How to set equal space between CardViews in RecyclerView?

I have some CardViews in my RecyclerView, and when I want to set space between them by adding margin, I get this:
As you can see, distance between cards is double. If I for example set margin just for top, left, and right, problem is solved but last card will touch the bottom of screen, and I don't want it. Like this:
As you can see, all spaces are equal and good, but there is no space in the bottom.
I have a MainActivity.java, activity_main.xml, recyclerview_row.xml, and MyAdapter.java in my project.
This is my activity_main.xml:
<?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"
tools:context=".MainActivity"
android:background="#dddddd">
<android.support.v7.widget.RecyclerView
android:layout_width="match_parent"
android:layout_height="match_parent"
android:id="#+id/recycler_view">
</android.support.v7.widget.RecyclerView>
</RelativeLayout>
And this is my recyclerview_row.xml:
<?xml version="1.0" encoding="utf-8"?>
<android.support.v7.widget.CardView
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="100dp"
xmlns:app="http://schemas.android.com/apk/res-auto"
app:cardElevation="2dp"
app:cardUseCompatPadding="true"
app:cardPreventCornerOverlap="false"
android:layout_margin="10dp">
<LinearLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="horizontal"
tools:ignore="UseCompoundDrawables">
<ImageView
android:layout_width="60dp"
android:layout_height="60dp"
android:id="#+id/image_view"
android:layout_gravity="center_vertical"
android:layout_margin="10dp"/>
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:id="#+id/text_view"
android:layout_gravity="center_vertical"
android:layout_margin="10dp"/>
</LinearLayout>
</android.support.v7.widget.CardView>
My question is how can I set equal distance between these Cards. Thank you.
Change your activity_main.xml as below:
<?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"
tools:context=".MainActivity"
android:background="#dddddd">
<android.support.v7.widget.RecyclerView
android:paddingBottom="10dp"
android:clipToPadding="false"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:id="#+id/recycler_view">
</android.support.v7.widget.RecyclerView>
The magic is done by this line: android:clipToPadding="false"
Try This in Main Activity,
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"

Centering the progressbar

I am trying to center my progressbar within the fragements screen. Here is what I have tried so far and what in my opinion shoul be correct:
<?xml version="1.0" encoding="utf-8"?>
<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">
<LinearLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:gravity="center"
android:orientation="vertical">
<ProgressBar
android:id="#+id/pgFragment"
style="?android:attr/progressBarStyleLarge"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="center"/>
</LinearLayout>
<ScrollView
android:id="#+id/scrollView"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:visibility="gone">
<android.support.v7.widget.RecyclerView
android:id="#+id/recyclerView"
android:layout_width="match_parent"
android:layout_height="wrap_content"
tools:listitem="#layout/recycler_row" />
</ScrollView>
</LinearLayout>
I tried deleting the wrapper layout, getting rid of the whole ScrollView (but as the visibility is set to gone, it shouldn't matter). The current result is, that the ProgressBar sticks to the top of the screen.
Might the cause be because of the Activity layout implementing a NestedScrollView?
<?xml version="1.0" encoding="utf-8"?>
<android.support.v4.widget.NestedScrollView xmlns:android="http://schemas.android.com/apk/res/android"

android:layout_height="match_parent"
app:layout_behavior="#string/appbar_scrolling_view_behavior"

tools:showIn="#layout/activity_main">
<fragment android:name="com.productlistpoc.recyclerview.RecyclerViewFragment"
android:id="#+id/fragment_recycler"
android:layout_width="match_parent"
android:layout_height="match_parent"
tools:layout="#layout/fragment_recycler" />
</android.support.v4.widget.NestedScrollView>
<?xml version="1.0" encoding="utf-8"?>
<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"

</LinearLayout>
<android.support.v7.widget.RecyclerView
android:id="#+id/recyclerView"
android:layout_width="match_parent"
android:layout_height="wrap_content" />
</FrameLayout>
Update your code like this
<?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">
<LinearLayout
android:id="#+id/linearLayout"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical">
<android.support.v7.widget.RecyclerView
android:id="#+id/recyclerView"
android:layout_width="match_parent"
android:layout_height="wrap_content"
tools:listitem="#layout/recycler_row" />
</LinearLayout>
<ProgressBar
android:id="#+id/pgFragment"
style="?android:attr/progressBarStyleLarge"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_centerInParent="true"/>
</RelativeLayout>
Don't use RecyclerView inside ScrollView. You have already used NestedScrollView as container layout so you don't need to add ScrollView.
Update your XML as below:
<?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.support.v7.widget.RecyclerView
android:id="#+id/recyclerView"
android:layout_width="match_parent"
android:layout_height="wrap_content">
</android.support.v7.widget.RecyclerView>
<RelativeLayout
android:id="#+id/layoutProgress"
android:layout_width="match_parent"
android:layout_height="match_parent">
<ProgressBar
android:id="#+id/pgFragment"
style="?android:attr/progressBarStyleLarge"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_centerInParent="true"/>
</RelativeLayout>
</RelativeLayout>
#. If you want to show/hide prograssbar, just show or hide the layoutProgress programmatically using layoutProgress.setVisibility(View.VISIBLE) and layoutProgress.setVisibility(View.GONE) method.
Hope this will help~

second fragment doesn't appear

Vertical layout:
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout 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:paddingTop="30dp"
android:paddingRight="16dp"
android:orientation="vertical"
tools:context="john.unitconverter.UnitConverter">
<fragment
android:id="#+id/unitConverter"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:name="john.unitconverter.ConverterFragment"></fragment>
</RelativeLayout>
horizontal layout
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="horizontal" android:layout_width="match_parent"
android:layout_height="match_parent">
<fragment

android:layout_weight="1"
android:layout_width="0dp"

android:layout_weight="1"
android:layout_width="0dp"
android:layout_height="match_parent"
android:name="john.unitconverter.DisclaimerFragment"></fragment>
</LinearLayout>
what's inside the second fragment
<FrameLayout 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"
tools:context="john.unitconverter.DisclaimerFragment">
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:id="#+id/disclaimer"
android:text="landscape mode is missing some features." />
</FrameLayout>
what happens is the second fragment doesn't show in landscape. why is that happening? basically, only the first fragment is showing up in the screen both horizontal and vertical layout.
thanks
As said in the comment you have to use the weight attribute:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="horizontal" android:layout_width="match_parent"
android:layout_height="match_parent">
<fragment
android:id="#+id/discConverter"
android:layout_weight="1"
android:layout_width="0dp"
android:layout_height="match_parent"
android:name="com.example.trist_000.teststack.ArticleFragment"></fragment>
<View
android:layout_width="0dp"
android:layout_height="match_parent"
android:layout_weight="0.1"/>
<fragment
android:id="#+id/unitConverter"
android:layout_weight="1"
android:layout_width="0dp"
android:layout_height="match_parent"
android:name="com.example.trist_000.teststack.ArticleFragment"></fragment>
</LinearLayout>
My fragment layout:
<?xml version="1.0" encoding="utf-8"?>
<FrameLayout 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="#android:color/holo_red_light">
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:id="#+id/disclaimer"
android:text="landscape mode is missing some features." />
</FrameLayout>
The result:

ListView takes up all space in LinearLayout

I have this LinearLayout containing a ListView and a LinearLayout:
<?xml version="1.0" encoding="utf-8"?>
<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">
<ListView
android:id="#+id/list_view"
android:layout_width="match_parent"
android:layout_height="fill_parent"/>
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:padding="10dp">
<EditText
android:layout_width="fill_parent"
android:layout_height="40dp"
android:hint="Hej"/>
</LinearLayout>
</LinearLayout>
The ListView takes up the entire layout and the LinearLayout with EditText gets added below the bottom edge of the screen and isn't visible. How can I fix this? I tried with layout_weight but didn't work.
That is because you are using fill_parent, and it will do exactly that.
You could try something along the lines of this... It will cause the ListView to expand to fill the space.
<?xml version="1.0" encoding="utf-8"?>
<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">
<ListView
android:id="#+id/list_view"
android:layout_width="match_parent"
android:layout_weight="1"
android:layout_height="0dp"/>
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:padding="10dp">
<EditText
android:layout_width="match_parent"
android:layout_height="40dp"
android:hint="Hej"/>
</LinearLayout>
</LinearLayout>
Another alternative is to use a RelativeLayout. So long as the height of the ListView is not wrap_content, it should be OK.
<?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:orientation="vertical">
<ListView
android:id="#+id/list_view"
android:layout_width="match_parent"
android:layout_above="#+id/footer"
android:layout_height="match_parent"/>
<LinearLayout
android:id="#+id/footer"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_alignParentBottom="true"
android:padding="10dp">
<EditText
android:layout_width="match_parent"
android:layout_height="40dp"
android:hint="Hej"/>
</LinearLayout>
</RelativeLayout>
