I wanted a cardview similar to this:
I wanted my CardView separated like that. The problem is, I don't know how to make CardView go edge to edge or match the width of the CardView to its parent. If I put shadows or setting the elevation at 4dp/8dp, the entire CardView adjusts to show the shadows on both end. Which is not what I want. This is worse when viewed on pre-lollipop.
I am believing this is just thick line separating it which can be done creating custom view with a custom drawable. But can this be done with just CardViews? I need my CardViews to go to the most edge and show separation at the bottom.
Here is my current layout. I created a separate layout file for each CardViews and included them in my fragment like this:
<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:fillViewport="false"
android:fitsSystemWindows="true"
tools:context="com.neonwarge.android.notifire.activity.TaskActivity"
android:orientation="vertical">
<include
layout="#layout/cardview1"
android:layout_width="match_parent"
android:layout_height="wrap_content"/>
<include
layout="#layout/cardview2"
android:layout_width="match_parent"
android:layout_height="wrap_content"/>
....
</LinearLayout>
And here is what generally a CardView looks like:
<?xml version="1.0" encoding="utf-8"?>
<merge
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto">
<android.support.v7.widget.CardView
android:layout_width="match_parent"
android:layout_height="wrap_content"
app:cardCornerRadius="4dp"
app:cardElevation="4dp"
app:cardUseCompatPadding="true"
app:cardPreventCornerOverlap="false">
<RelativeLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:paddingLeft="#dimen/activity_horizontal_margin"
android:paddingStart="#dimen/activity_horizontal_margin"
android:paddingRight="#dimen/activity_horizontal_margin"
android:paddingEnd="#dimen/activity_horizontal_margin"
android:paddingBottom="#dimen/activity_vertical_margin"
android:layout_marginTop="#dimen/activity_vertical_margin">
...
</RelativeLayout>
</android.support.v7.widget.CardView>
</merge>

Shadows seem to cut off on some of my CardView usages.
Any idea why? looks like removing the padding on the parent resolves the issue, but I do want the padding. And I don't want to use margin on the inner card, because there are other views aligned and I prefer having the padding set on the parent to apply to all children
Any solutions?

I'm trying to add a margin around my RecyclerView whilst enusring it can scroll vertically but for some reason the scrollbar does not position itself at the end/right of the screen. Is this an issue specific to Android X?
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:id="#+id/myLinearLayout"
android:orientation="vertical"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:paddingTop="#dimen/activity_vertical_margin"
android:paddingBottom="#dimen/activity_vertical_margin"
android:paddingStart="#dimen/activity_horizontal_margin"
android:paddingEnd="#dimen/activity_horizontal_margin">
<androidx.recyclerview.widget.RecyclerView
android:id="#+id/myRecyclerView"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:scrollbars="vertical"/>
</LinearLayout>
Is this an issue specific to Android X?
Not really.
The issue here is you are specifying padding on the container of the RecyclerView.
android:paddingTop="#dimen/activity_vertical_margin"
android:paddingBottom="#dimen/activity_vertical_margin"
android:paddingStart="#dimen/activity_horizontal_margin"
android:paddingEnd="#dimen/activity_horizontal_margin"
This is because the rect used to draw the scrolls bars are limited to the rect where is drawn the RecyclerView. This is also the reason because the scroll bars restraint on the top.
Remove these and you are going to obtain the scroll bars positioned on the border of the screen.

Explanation:
The bar is in the recyclerview, the recycler is constrained by the padding.
Quick fix:
Add padding to the recylerview
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:id="#+id/myLinearLayout"
android:orientation="vertical"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:paddingTop="#dimen/activity_vertical_margin"
android:paddingBottom="#dimen/activity_vertical_margin">
<androidx.recyclerview.widget.RecyclerView
android:id="#+id/myRecyclerView"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:scrollbars="vertical"
android:paddingEnd.../>
</LinearLayout>
Good practice:
List should be full width so user interactions are not hindered by unknown spacings. Add the padding to the item you are inflating in the adapter.
My Linear Layout was taking too much space. So I decided to put it inside a ScrollView.
The layout has an EditText at the bottom for user input. To make the layout resize itself in AndroidManifest.xml for the Activity I put:
android:windowSoftInputMode="adjustPan"
It was OK for when I just had a Linear Layout, but now in combination with Scroll View I get a blank space, I think Android is trying to make space for the keyboard.
Layout.xml:
<ScrollView android:layout_width="match_parent"
android:layout_height="match_parent"
xmlns:android="http://schemas.android.com/apk/res/android">
<androidx.appcompat.widget.LinearLayoutCompat
android:isScrollContainer="false"
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:orientation="vertical"
tools:context=".MainActivity"
android:background="#color/colorPrimary">
...
</androidx.appcompat.widget.LinearLayoutCompat>
</ScrollView>
Before clicking keyboard
After clicking keyboard
Replace with following code
<ScrollView android:layout_width="match_parent"
android:layout_height="match_parent"
android:fillViewport="true"
xmlns:android="http://schemas.android.com/apk/res/android">
<androidx.appcompat.widget.LinearLayoutCompat
android:isScrollContainer="false"

android:layout_width="match_parent"

...
</androidx.appcompat.widget.LinearLayoutCompat>

I have a question that i couldn't Find Any Answer For it.
How can I Make An Layout Scrolling And Make Another Layout that doesn't Scroll?
On the other hand i want to make a layout Including Some buttons that scrolls if necessary and i want to put Two buttons at the bottom of the screen and i don't want them to disappear when scrolling.
<?xml version="1.0" encoding="utf-8"?>
<ScrollView
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:background="#drawable/background"
android:layout_width="match_parent"
android:layout_height="match_parent">
<RelativeLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
tools:context="com.myname.myapp.MainActivity">
// a bunch of Buttons and TextViews
</RelativeLayout>
</scrollView>
<RelativeLayout
android:layout_width="match_parent"
android:layout_height="wrap_content">
// two Moveless Buttons
</RelativeLayout>
But it doesn't Work.
Your ScrollView has width and height that matches the parent. This means it takes up the entire space available leaving nothing for the RelativeLayout. You probably want to wrap what you already have inside a LinearLayout and then use layout_weight attribute to divide the space up.
I'm not sure I understand what You want to do. But try this and give feedback
( code example not tested in Android Studio)
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
>
<ScrollView
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:background="#drawable/background"
android:layout_width="match_parent"
android:layout_height="match_parent">
<RelativeLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
tools:context="com.myname.myapp.MainActivity">
// a bunch of Buttons an TextViews
</RelativeLayout>
</ScrollView>
<RelativeLayout
android:layout_width="match_parent"
android:layout_height="80dp (for example)>"
android:layout_alignParentBottom="true">
// two Moveless Buttons
</RelativeLayout>
</RelativeLayout>
Make your root a vertical linearlayout with a scrollview, to hold the scrollable views, and a RelativeLayout, to hold your buttons.
You can take advantage of the LinearLayout's weighting ability by applying a weight of 1 to the Scrollview so it takes up as much room it can while the button-holding-RelativeLayout will be the size of your biggest button.
Here is an example:
<?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:orientation="vertical"
android:layout_width="match_parent"
android:layout_height="match_parent">
<ScrollView
android:background="#drawable/background"
android:layout_width="match_parent"
android:layout_height="0dp"
android:layout_weight="1">
<RelativeLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
tools:context="com.myname.myapp.MainActivity">
// a bunch of Buttons an TextViews
</RelativeLayout>
</ScrollView>
<RelativeLayout
android:layout_width="match_parent"
android:layout_height="wrap_content">
// two Moveless Buttons
</RelativeLayout>
</LinearLayout>
HTHS!
I have two views with the same elevation beside each other. My wanted behaviour is that they won't cast a shadow over each other as they have the same elevation, however, what is happening is that the view on the left, casts a shadow on the right. They are not the same size so I can't put them both in another view and apply an elevation to that view.
Is this the expected behaviour? Is there a way round it?
Edit:
I just recreated with simpler views, here is the code.
I also noticed it has the expected behaviour if I have the view directly in the layout and don't include it as I did it in this example and as I need it to work.
<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="horizontal"
android:paddingLeft="#dimen/activity_horizontal_margin"
android:paddingRight="#dimen/activity_horizontal_margin"
android:paddingTop="#dimen/activity_vertical_margin"
android:paddingBottom="#dimen/activity_vertical_margin"
tools:context=".MainActivity"
android:background="#android:color/holo_green_dark">
<LinearLayout
android:layout_width="200dp"
android:layout_height="200dp"
android:background="#android:color/holo_red_dark"
android:elevation="24dp"/>
<include layout="#layout/test"/>
</LinearLayout>
And here is the include:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="wrap_content"
android:layout_height="wrap_content">
<LinearLayout
android:layout_width="100dp"
android:layout_height="100dp"
android:background="#android:color/holo_red_dark"
android:elevation="24dp"/>
</LinearLayout>
And the screenshot:
See the hierarchy you have:
So you have applied elevation to 1 and 3, which are not siblings. Apparently, if one view is higher in the hierarchy, than it should cast a shadow, regardless those views have same elevation or no.
Had you applied elevation to 2 instead of 3 you would not see shadow effect.
So if you just change your test.xml to this:
<LinearLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:elevation="24dp">
<LinearLayout
android:layout_width="100dp"
android:layout_height="100dp"
android:background="#android:color/holo_red_dark"/>
</LinearLayout>
You'd get this output:
