Recyclerview in scrollview

This is the code :
<?xml version="1.0" encoding="utf-8"?>
<ScrollView xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical" android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="#color/grey_f2"
android:fillViewport="true"
>
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="vertical"
>
<android.support.v7.widget.RecyclerView
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:id="#+id/rv_achievement_badges"
android:focusableInTouchMode="false"
/>
<LinearLayout
android:background="#color/white"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical"
android:padding="25dp"
>
<com.sharesmile.share.views.LBTextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="#string/hall_of_fame"
android:layout_marginTop="10dp"
android:layout_marginBottom="10dp"
android:textColor="#color/black_64"
android:textSize="20sp"
/>
<android.support.v7.widget.RecyclerView
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:id="#+id/rv_hall_of_fame"
android:focusableInTouchMode="false"
/>
</LinearLayout>
</LinearLayout>
</ScrollView>
The issue is rv_hall_of_fame does not show all items.
tried nestedsrollview, viewport, canScrollVertically and setNestedScrollingEnabled and nothing is working. Can you let me know.

You should remove the second recyclerview from the linearlayout. Maybe that is the reason you can't see all items.
EDIT:
I think you should use NestedScrollView. I had the same problem in one of my projects and I changed my code to below which solved my problem.
<?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"

android:fillViewport="true"
android:focusableInTouchMode="true">
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="vertical">
<android.support.v7.widget.RecyclerView
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:id="#+id/rv_achievement_badges"/>
<com.sharesmile.share.views.LBTextView
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:text="#string/hall_of_fame"
android:layout_marginTop="10dp"
android:textColor="#color/black_64"
android:textSize="20sp"
android:background="#color/white"
android:paddingLeft="25dp"
android:paddingTop="36dp"/>
<android.support.v7.widget.RecyclerView
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:id="#+id/rv_hall_of_fame"
android:background="#color/white"
android:layout_marginBottom="7dp"
android:paddingBottom="30dp"
android:paddingTop="30dp"
android:paddingLeft="25dp"
android:paddingRight="25dp"/>
</LinearLayout>
</android.support.v4.widget.NestedScrollView>

It's not wise to put a RecyclerView or a ListView inside a ScrollView. Android doesn't know how to handle user events. In addition, in your case, you have two RecyclerView inside that root ScrollView... It's madness both for the Android UI framework and for the user.
A solution could be to only use one RecyclerView that handles the scroll user action, and an Adapter that knows how to render everything you use: achievements badges, the hall of fame label, and the players. So, you'll only need one RecyclerView, and it will work like a charm.

Android Scrollview content size smaller when should be

I want to have a "fixed_space" at the top of screen and a "scrollview" at the bottom of the screen which should be below fixed_space. The rest of the screen is a container "rest_space".
Unfortunately my scrollview has a shorter height(by 100dp which fixed_space has) ,if content is too big/scrollable.
I tried to achieve same with ConstraintLayout and RelativeLayout, but I have got same result.
Any ideas why scrollview has 100dp shorter height, as it should be?
EDIT: Scrollview should take as much space as she needs.
<?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">
<View
android:id="#+id/fixed_space"
android:layout_width="match_parent"
android:layout_height="100dp"
android:background="#android:color/holo_red_dark" />
<View
android:id="#+id/rest_space"
android:layout_width="match_parent"
android:layout_height="0dp"
android:layout_weight="1"
android:background="#android:color/black" />
<ScrollView
android:id="#+id/scrollview"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:background="#android:color/holo_green_dark"
android:fillViewport="true">
<TextView
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:text="START OF SCROLLVIEW \n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\nMIDDLE OF SCROLLVIEW \n\n\n\n\n\n\n\n\n\n\n\nEND OF SCROLLVIEW" />
</ScrollView>
</LinearLayout>

Try this:
<?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">
<View
android:id="#+id/fixed_space"
android:layout_width="match_parent"
android:layout_height="100dp"
android:background="#android:color/holo_red_dark" />
<RelativeLayout
android:layout_width="match_parent"
android:layout_height="match_parent">
<View
android:id="#+id/rest_space"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_above="#+id/scrollview"
android:background="#android:color/black" />
<ScrollView
android:id="#+id/scrollview"
android:layout_alignParentBottom="true"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:background="#android:color/holo_green_dark"
android:fillViewport="true">
<TextView
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:text="START OF SCROLLVIEW \n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\nMIDDLE OF SCROLLVIEW \n\n\n\n\n\n\n\n\n\n\n\nEND OF SCROLLVIEW" />
</ScrollView>
</RelativeLayout>
</LinearLayout>

Ok, I think this should solve your probem:
First, I started by using RelativeLayout. I did it in order to get the fixed_space aligned to the top and the scrollview aligned to the bottom.
Then I changed the View for a LinearLayout and put a TextView within it so I could use wrap_content and this is the tricky part:
When you use ScrollView with wrap_content and a View with the weight stuff, Android can't make the calculations it needs to get the screen drawed because there is no reference. When I put the TextView with wrap_content itself that gives the reference because Android know the size of the text.
You don't have to use the TextView but you will need anything that gives Android that reference.
In this case, the scrollview is going to be stretched, not the LinearLayout. If you want the second to get strached, then I'm afraid you are going to need to set a fixed height to your scrollview.
<?xml version="1.0" encoding="utf-8"?>

Android ListView inside ScrollView not proper

I am sorry, I am new to android xml part. I am setting my listview which is inside scroll view to full screen but its frame is still small. How to resolve it? I have already set both width and height to "match_parent". Can someone help?
<?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:id="#+id/activity_main"
android:layout_width="match_parent"
android:layout_height="match_parent"
tools:context="com.stacktips.speechtotext.MainActivity">
<ScrollView
android:layout_width="match_parent"
android:layout_height="match_parent">
<ListView
android:id="#+id/list"
android:layout_width="match_parent"
android:layout_height="match_parent"
tools:listitem="#layout/row" >
</ListView>
</ScrollView>
<LinearLayout
android:id="#+id/btnSpeakContainer"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_alignParentBottom="true"
android:background="#f5f5f5"
android:gravity="center_horizontal"
android:orientation="vertical"
android:padding="20dp">
<ImageButton
android:id="#+id/btnSpeak"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:background="#null"
android:padding="16dp"
android:scaleType="fitCenter"
android:src="#mipmap/ic_microphone_2" />
<TextView
android:id="#+id/textView"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_below="#id/btnSpeak"
android:layout_margin="10dp"
android:text="#string/hint" />
</LinearLayout>
</RelativeLayout>

Putting the ListView inside a ScrollView means the ListView will not go to its full height. Take out the ScrollView surrounding the ListView and this should work for you :) ListView itself is scrollable.

ListView not scrolling for Xamarin.Android app

I've placed a fragment tag on my page for a google map and a listview surrounded by a linear layout tag underneath the map. Does anyone know why my list view isn't scrolling. I set my listview fastscrollenabled setting to true and it still doen't scroll.
var locationService = new LocationService(_geoCoder);
listView.Adapter = new ListOfLocationAdapter(this, locationService.GetLatLongOfAddresses());
this.listView.FastScrollEnabled = true;
Here is the XAML I use for the layout.
<?xml version="1.0" encoding="utf-8"?>
<GridLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:rowCount="2"
android:columnCount="1">
<fragment
android:id="#+id/map"
android:layout_width="match_parent"
android:layout_height="300dp"
class="com.google.android.gms.maps.MapFragment" />
<LinearLayout
android:id="#+id/linearLayout1"
android:orientation="vertical"
android:layout_width="match_parent"
android:layout_height="match_parent">
<ListView
android:id="#+id/List"
android:layout_width="match_parent"
android:layout_height="0dp"
android:layout_weight="1"
android:cacheColorHint="#FFDAFF7F"/>
</LinearLayout>
</GridLayout>
Here is the listadapter code:
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:minHeight="50dp"
android:orientation="vertical"
android:background="#ffffff">
<LinearLayout
android:id="#+id/Text"
android:layout_width="fill_parent"
android:layout_height="50dp"
android:orientation="vertical">
<TextView
android:id="#+id/CustomerName"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:textColor="#000000"
android:textSize="20dip"
android:textStyle="italic"
android:paddingLeft="10dip" />
<TextView
android:id="#+id/Address"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:textSize="14dip"
android:textColor="#000000"
android:paddingLeft="10dip" />
</LinearLayout>
</RelativeLayout>
I tried removing the relativelayout tag, but that didn't do anything for me.

Set weight to your listview & set height to 0dp. This will make it auto-fill any remaining space, causing the internal items of the listview to scroll.
<ListView
android:id="#+id/List"
android:layout_width="match_parent"
android:layout_height="0dp"
android:layout_weight="1"
android:cacheColorHint="#FFDAFF7F" />

When I move the linearlayout around both the fragment and listview the scrolling starts working. For some reason the linear layout was showing off of the bottom of the android layout making it look like it wasn't scrolling until I added more records.
<GridLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:rowCount="2"
android:columnCount="1">
<LinearLayout
android:id="#+id/linearLayout1"
android:orientation="vertical"
android:layout_width="match_parent"
android:layout_height="match_parent">
<fragment
android:id="#+id/map"
android:layout_width="match_parent"
android:layout_height="300dp"
class="com.google.android.gms.maps.MapFragment" />
<ListView
android:id="#+id/List"
android:layout_width="match_parent"
android:layout_height="0dp"
android:layout_weight="1"
android:cacheColorHint="#FFDAFF7F" />
</LinearLayout>
</GridLayout>

I had the same problem. I just set layout_height of my ListView to match_parent value. This solved my problem.

How should i solve this problem. I want to add ScrollView to activity which will have 9 to 10 horizontal RecyclerView

Set the height of the Recyclerviews to an actual dp value
