I have already searched SO and none of the answer helped me.
Here is my layout xml:
<android.support.v7.widget.CardView
android:id="#+id/layout_building"
android:layout_width="0dp"
android:layout_height="wrap_content"
android:layout_marginTop="#dimen/_8dp"
app:layout_constraintEnd_toStartOf="#+id/scrollview_nested_fragment_container"
app:layout_constraintHorizontal_weight="1"
app:layout_constraintStart_toStartOf="parent"
app:layout_constraintTop_toBottomOf="#+id/views_container">
<ScrollView
android:layout_width="match_parent"
android:layout_height="wrap_content">
<LinearLayout
android:id="#+id/layout_building_container"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="vertical"/>
</ScrollView>
</android.support.v7.widget.CardView>
I'm adding child views to my LinearLayout dynamically via code. I have also tried to move the ScrollView tag to wrap CardView but still no luck. Is this a limitation of CardView or do any one know a working solution to this.
It will be better if you use NestedScrollView .
NestedScrollView is just like ScrollView, but it supports acting as
both a nested scrolling parent and child on both new and old versions
of Android.
<android.support.v4.widget.NestedScrollView
android:layout_width="match_parent"
android:layout_height="match_parent">
//Your CHILD Layout
</android.support.v4.widget.NestedScrollView>
FYI
You can put your CardView under ScrollView.
Okay first of all thanks to every one for helping with your valauble suggestions. The actual problems lies with the ConstraintLayout. All needs to be done is add a constraint app:layout_constraintBottom_toBottomOf="parent" to the cardview and set android:layout_height="0dp". The cardview didn't have any boundary inforced. Unlike LinearLayout and RelativeLayout which by default inforce the boundary to their child views.
set this property in ScrollView
android:fillViewport="true"
and set height of cardview to match parent or fixed

The problem is that the ScrollView scrolls till it completes all the content of my layout, then it keeps scrolling and shows empty layout. It keeps scrolling for a long empty length. I guess the problem is in using the RecyclerView inside a ScrollView, and I just know that this will result in a poor UI experience, but the point now is to make it work
Here is the component tree of my layout
And here is the snippet of the xml code for the part of the ScrollView
<ScrollView
android:layout_width="match_parent"
android:layout_height="0dp"
android:layout_weight="1"
android:background="#color/white_smoke"
android:fillViewport="true">
<LinearLayout
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:orientation="vertical">
<androidx.constraintlayout.widget.ConstraintLayout...>
<LinearLayout
android:id="#+id/frameLayout2"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="vertical">
<androidx.recyclerview.widget.RecyclerView
android:id="#+id/comments_recycler_view"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:background="#color/white_smoke" />
</LinearLayout>
</LinearLayout>
After trying a few solutions. Wrapping the RecyclerView in a RelativeLayout instead of LinearLayout has solved the problem for me. A final thing to not forget, do not use RecyclerView in a ScrollView as the RecyclerView will not recycle its views. You can do that if you are sure that there are no many items in the RecyclerView.
I have no idea how this can happen, but I have a ConstraintLayout with a CardView inside. Inside said CardView is a LinearLayout. That LinearLayout overlaps the parent on the end. Check the screenshot for more info. If I remove the android:layout_margin from the cardView, the inner layout looks good again, but adding margin to start seems to just push the entire layout to and over the end of the parent. It doesnt matter what sort of layout is used inside the CardView. The issue affects them all.
<androidx.constraintlayout.widget.ConstraintLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:animateLayoutChanges="true"
android:background="#color/colorWhite">
..
<androidx.cardview.widget.CardView
android:id="#+id/wakeuptimer_status_layout"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_margin="#dimen/md_keylines"
app:layout_constraintTop_toTopOf="parent">
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="vertical">
.....
You need to change the Linearlayout height to match-parent instead of wrap_content. With wrap_content you aren't restricting the size of the Linearlayout view to the size of the CardView.
<LinearLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical">
I'm facing a tricky situation here and I don't know how to solve this problem.
In my project I have a custom BottomSheetDialogFragment and in the layout a FrameLayout to add or replace Fragments.
Now I have a Fragment and inside I have a RecyclerView with the height:="wrap_content" because I want the BottomSheetDialogFragment only use the necessary space. Everything looks great, the problem appear when I put another view inside of the same layout and set the RecyclerView bellow or above of that view.
The RecyclerView ignores the size of the other view (or views) and always grows to the max screen size, and then it's no possible to see a few elements and even scroll.
I saw a solution, some developers are suggesting to add paddingBottom equals to the height of the view. But in my case doesn't works because I want to have a dynamic solution.
Above I'll share a few images of the problem and GitHub Repository with a sample.
Thanks for your attention!
I've manage to do what you need just need to use this as your fragment_sample.xml:
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="vertical">
<android.support.v7.widget.RecyclerView
android:id="#+id/rclItems"
android:layout_width="match_parent"
android:layout_height="0dp"
android:layout_weight="1"
app:layoutManager="android.support.v7.widget.LinearLayoutManager"/>
<Button
android:id="#+id/btnAddMoreItems"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_below="#+id/rclItems"
android:text="#string/add_1_item"/>
</LinearLayout>
Explanation
Using a LinearLayout gives you the ability to work with weight, and the vertical orientation allows you to place an item below the other. The weight on the recyclerview will increase the height of it as needed until filling the screen. The next item you add would be added to the recyclerview but you'll need to scroll the list to see it
The android developers blog says that :-
The scrolling containers in your bottom sheet must support nested scrolling .
Try changing your fragment_sample.xml as below to make the recyclerview scroll working and to make the add button persistent.
<?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"
android:layout_width="match_parent"
android:layout_height="wrap_content">
<android.support.v4.widget.NestedScrollView
android:layout_width="match_parent"
android:id="#+id/next"
android:layout_above="#id/btnAddMoreItems"
android:layout_height="wrap_content">
<android.support.v7.widget.RecyclerView
android:id="#+id/rclItems"
android:layout_width="match_parent"
android:layout_height="wrap_content"
/>
</android.support.v4.widget.NestedScrollView>
<Button
android:id="#+id/btnAddMoreItems"
android:layout_width="match_parent"
android:layout_alignParentBottom="true"
android:layout_height="wrap_content"
android:text="#string/add_1_item"/>
</RelativeLayout>
Note: making bottomsheet layout a child view of CoordinatorLayout will allow you to get the implement BottomSheetBehavior and recieve its transitions callbacks .
I have wrapped an activity in an scroll view like following.
<ScrollView
android:layout_width="match_parent"
android:layout_height="match_parent"
android:fillViewport="true"
>
<include layout="#layout/content_form" />
</ScrollView>
I have around 15 fields in the content_form layout, the issues is that the last item in content_form layout is attached with bottom.
I need to add a margin below the scroll view, i have tried giving margin to scrollviewand the last item of content_form field, but nothing is working.
I need to know how to add margin at the bottom of page when using scroll view.
If you want the scrolling margin to be within the content, it would be best to add it to content_form. You should be able to accomplish this by either adding paddingBottom to your parent container in that layout, or layout_marginBottom on your last view aligned to the parent bottom.
This make padding under the last item in scroll view. may be good for you
<androidx.core.widget.NestedScrollView
android:layout_width="match_parent"
android:paddingBottom="80dp"
android:clipToPadding="false"
android:layout_height="match_parent">
You can either use Space or View for the purpose like
<Space
android:layout_width="100dp"
android:layout_height="match_parent"/>
Or,
<View
android:layout_width="100dp"
android:layout_height="match_parent"
android:layout_weight="1"/>
Here, you need to give padding, not margin.
Try giving padding to the ScrollView.
I've had issues with ScrollView being ill-behaved when it's direct childview is not a LinearLayout. So please try LinearLayout as direct child of your scrollView and place <include> layout inside LinearLayout.
<ScrollView
android:layout_width="match_parent"
android:layout_height="match_parent">
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="vertical">
... your layouts go here ...
</LinearLayout>
</ScrollView>
I have the listView in the NestedScrollView since the nested scrollView are out of the screen so some list will not be shown
You need to use RecyclerView inside NestedScrollView. And wrap it with custom LinearLayoutManager.
How to use RecyclerView inside NestedScrollView?
For the fast fix just put it in linear layout
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content">
<com.nhaarman.listviewanimations.itemmanipulation.DynamicListView
android:id="#+id/listViewTaskInComplete"
android:layout_width="match_parent"
android:layout_height="match_parent"
/>
</LinearLayout>
