android layout scrolling with gridview and RecyclerView

I have layout with RecyclerView scrolling horizontally and gridview vertically.
but recyclerview dosen't scroll up in activity, leaving gridview scrolling vertically below horizontal recyclerview list.
i want recyclerview to be scrolled horizontally while whole layout vertically scrolling.
content_main.xml
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"

why you are using gridview in recycler view. it will not behave correctly. if you want a grid view you can use recyclerview as a grid view.
set you recycler view layout manger as StaggeredGridLayoutManager. use it like.
recyclerView.setLayoutManager(new StaggeredGridLayoutManager(2,StaggeredGridLayoutManager.VERTICAL));
take a refreance from https://developer.android.com/reference/android/support/v7/widget/StaggeredGridLayoutManager.html

Your main layout should be scroll view and your recycle view height should not match parent .
you need to set height of grid view dynamically based on number of children.

ListView not scrolling inside of NestedScrollView

I am using a ListView inside of a NestedScrollView.
The List expand to match the parent but there is no scrolling now
Here is my layout :
<android.support.v4.widget.NestedScrollView
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="wrap_content"
app:layout_behavior="#string/appbar_scrolling_view_behavior"
android:fillViewport="true"
>
<LinearLayout
android:orientation="vertical"
android:layout_width="match_parent"
android:layout_height="wrap_content">
<ListView
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_centerHorizontal="true"
android:id="#+id/workExperienceListLV"
android:divider="#null"
android:listSelector="#android:color/transparent"
android:dividerHeight="0dp"/>
</LinearLayout>
</android.support.v4.widget.NestedScrollView>
This line did not help :
android:fillViewport="true"
Thanks for the help!

Use ViewCompat.setNestedScrollingEnabled() and you should be fine.

this is because of using a ListView inside a scrollview(NestedScrollView).becacuse both having scroll ,if you want to scroll this you just reduce the width of the listview to half of the screen.
like this..
<ListView
android:layout_width="70dp"
android:layout_height="wrap_content"
android:layout_centerHorizontal="true"
android:id="#+id/workExperienceListLV"
android:divider="#null"
android:listSelector="#android:color/transparent"
android:dividerHeight="0dp"/>

How can I add horizontal, vertical RecyclerView inside a vertical scroll

I want to add vertical as well as horizontal RecyclerViews inside a vertical scrollview.
Is it possible to have multiple recycler views inside vertcal scrollview
what control I need to use.
Also RecyclerView nested in one ScrollView is not good practice so can anybody tell me whats right way to do it can I add RecyclerView inside another RecyclerView or I need to use horizontal and vertical scrollview only to achieve this.

You can do something like this for getting two RecyclerView nested in one ScrollView which is by the way not recommended.
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:custom="http://schemas.android.com/apk/res-auto"
android:layout_width="match_parent"
xmlns:app="http://schemas.android.com/tools"
android:focusableInTouchMode="true"
android:padding="8dp"
android:background="#drawable/old_map"
android:layout_height="match_parent">
<ScrollView
android:layout_below="#+id/toolbar"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical"
android:scrollbars="none">
<RelativeLayout
android:layout_width="match_parent"
android:layout_height="600dp">
<view
android:scrollbarSize="6dp"
android:id="#+id/recent_post"
class="android.support.v7.widget.RecyclerView"
android:layout_width="match_parent"
android:layout_height="400dp"
android:scrollbars="vertical" />
<view
android:scrollbarSize="6dp"
android:id="#+id/recent_post"
class="android.support.v7.widget.RecyclerView"
android:layout_width="match_parent"
android:layout_height="400dp"
android:scrollbars="horizontal" />
</RelativeLayout>
</ScrollView>
</RelativeLayout>

I don't namely know what kind of scrolling do you want but it is possible to use both scrolls at the same time:
<LinearLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical" >
<HorizontalScrollView
android:id="#+id/HorizontalScrollView02"
android:layout_width="match_parent"
android:layout_height="match_parent" >
<LinearLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical" >
<!-- HERE YOUR CODE-->
</LinearLayout>
</HorizontalScrollView>
</LinearLayout>
</ScrollView>

How do you make a LinearLayout scrollable?

I have lot of items on the screen and I need to use the scrollbar so the user can scroll down. However, the scroll is either not visible or it's not working. How is it possible to add a scrollbar to a LinearLayout?

Wrap the linear layout with a <ScrollView>
See here for an example:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout
android:layout_width="fill_parent"
android:layout_height="fill_parent"
xmlns:android="http://schemas.android.com/apk/res/android">
<ScrollView
android:layout_width="fill_parent"
android:layout_height="wrap_content">
<LinearLayout
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:orientation="vertical">
<!-- Content here -->
</LinearLayout>
</ScrollView>
</LinearLayout>
Note: fill_parent is deprecated and renamed to match_parent in API Level 8
and higher.

<ScrollView
xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/scroll"
android:layout_width="match_parent"
android:layout_height="wrap_content">
<LinearLayout
android:id="#+id/container"
android:orientation="vertical"
android:layout_width="match_parent"
android:layout_height="wrap_content">
</LinearLayout>
</ScrollView>

You need to wrap your linear layout with a scroll view
<ScrollView xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/scroll"
android:layout_width="match_parent"
android:layout_height="match_parent">
<LinearLayout
android:id="#+id/container"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="vertical">
</LinearLayout>
</ScrollView>

This can be done using the tag <ScrollView>. For ScrollView, one thing you have to remind that, ScrollView must have a single child.
If you want your full layout to be scrollable then add <ScrollView> at the top. Check the example given below.
<ScrollView xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/scroll"
android:layout_width="match_parent"
android:layout_height="match_parent">
<LinearLayout
android:id="#+id/container"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="vertical">
<!-- Content here -->
</LinearLayout>
</ScrollView>
But if you want some part of your layout to be scrollable then add <ScrollView> within that part. Check the example given below.
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="400dp">
<ScrollView
android:layout_width="match_parent"
android:layout_height="match_parent">
<LinearLayout
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:orientation="vertical">
<!-- Content here -->
</LinearLayout>
</ScrollView>
</LinearLayout>

Here is how I did it by trial and error.
ScrollView - (the outer wrapper).
LinearLayout (child-1).
LinearLayout (child-1a).
LinearLayout (child-1b).
Since ScrollView can have only one child, that child is a linear layout. Then all the other layout types occur in the first linear layout. I haven't tried to include a relative layout yet, but they drive me nuts so I will wait until my sanity returns.

you need to use the following attribute and enclose it within the linear layout
<LinearLayout ...>
<scrollView ...>
</scrollView>
</LinearLayout>

You need to place ScrollView as the first child of Layout file and now put your linearlayout inside it. Now, android will decide on the basis of content and device size available whether to show a scrollable or not.
Make sure linearlayout has no sibling because ScrollView can not have more than one child.

<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"
tools:context=".MainActivity">
<ScrollView
android:layout_width="match_parent"
android:layout_height="match_parent">
<LinearLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical">
<---------Content Here --------------->
</LinearLayout>
</ScrollView>
</LinearLayout>

Whenever you wanted to make a layout scrollable, you can use <ScrollView> With a layout or component in it.

You can add an atrribute in linearLayout : android:scrollbars="vertical"
