I'd like to add a divider to an alert dialog at the bottom, similar to the one it shows when there are long list views (see image).
However, I've added a customized view, because I want to be able to use a generic layout for all my AlertDialogs in the whole app. Now there is a very huge space between view and buttons. Additionally the listview, which used to have the divider (from the original AlertDialog view), is not available anymore and my layout has it's own recyclerview. (Because they are recommended nowadays.)
I tried adding a divider in my custom view, but this divider is bound to the padding of it's parent and therefore doesn't fill the whole dialog (and is still heavily spaced from the buttons).
So I'd basically like to access the area of the buttons in the alertdialog to add a divider at the top of this view. (Which then would be full width and below the padding of the custom view.) It would be great, if this was possible with the Builder, because I sometimes use positive and negative buttons and sometimes only negative or only positive and customizing all that in a generic layout as well would be a huge effort.
Here's my custom layout (with divider). I'm using the MaterialAlertDialogBuilder. Note: I could remove the padding at the bottom to remove the space, but then it looks smashed and the problem with the width of the divider still isn't fixed.

Goal:
Edit 1: It should also work with the recyclerview being filled, so it has to scroll, where the current solutions let the recyclerview disappear in the padding. There's 1 1/2 items left, but I can't scroll any further. (Image is without marginTop on Divider, with margin it actually disappears as well)
Solution:
If you don't have a scrolling recyclerview with many items, #shraddha patel s approach works just fine. However, if you have one, to avoid cutting off the last items, you need to use a LinearLayout instead of a ConstraintLayout for the contentview, as shown in this somewhat related bug report: https://github.com/material-components/material-components-android/issues/1336
However, if you have items below the recyclerview, the parent layout still needs to stay a constraint layout or the divider will disappear in scrolling lists.
So the working solution for me now is:
<?xml version="1.0" encoding="utf-8"?>

I created a component for my app which I use like a card. It has some textviews and an end image, but the image always appears with some withe border liek in the image bellow:
I tried everything to fix it but I can figure out how and it's important because the component it's used in almost all the app and in all of them the all the images appear with some withe border.
Component code:

app:cardDescription="#string/home_card_selfdiagnosis_description"
app:cardEndImage="#string/image_home_card_symptomchecker"
app:cardHeader="#string/home_card_selfdiagnosis_header" />
Set a background which is easily visible(eg: red) to your cardview and run the app.
If the red section gets visible it means the inner constraint layout isn't wrapping the cardview completely . If that is the case I would suggest experimenting with scale type as so
<androidx.appcompat.widget.AppCompatImageView
android:id="#+id/image_card_end"
android:layout_width="wrap_content"

Vertically, the layout does what I want: it puts the last layout and fills the screen.
However, when the device is flipped horizontally, the bottom portion (the nested constraintlayout) disappears due to the constraint on itself of app:layout_constraintBottom_toBottomOf="parent"
"How do I fill the screen with a second layout while still having it scroll horizontally ?"
I have attached pics and a demo repository to isolate the problem.

After running my application the layouts are presented in the image below:
I tried adding a bottom margin to the recycle view, but this has not resolved the issue. I used the following links as references: RecyclerView is cutting off the last item, RecyclerView cutting off last item and tried making those changes with no luck
Your RecyclerView is not properly constrained. You can either use 0dp (MATCH_CONSTRAINT) for the height and use all available space:
<android.support.v7.widget.RecyclerView
android:id="#+id/recyclerView"
android:layout_width="0dp"
android:layout_height="0dp"
android:layout_marginTop="8dp"
android:visibility="visible"
app:layout_constraintBottom_toBottomOf="parent"
app:layout_constraintLeft_toLeftOf="parent"
app:layout_constraintRight_toRightOf="parent"
app:layout_constraintTop_toBottomOf="#+id/toolbar" />
or if you want to keep it as wrap_content you will need to set app:layout_constrainedHeight="true" attribute to enforce the constraints:
<android.support.v7.widget.RecyclerView
android:id="#+id/recyclerView"
android:layout_width="0dp"
android:layout_height="wrap_content"
android:layout_marginTop="8dp"
android:visibility="visible"
app:layout_constrainedHeight="true"
app:layout_constraintBottom_toBottomOf="parent"
app:layout_constraintLeft_toLeftOf="parent"
app:layout_constraintRight_toRightOf="parent"
app:layout_constraintTop_toBottomOf="#+id/toolbar" />
I tried all the available option from most of possible site but I didn't get the solution.
Then, I think can I use bottom padding? And Yes, It's work for me.
I am sharing the code to you.
Nothing more attribute required other than height, width & padding.
<android.support.v7.widget.RecyclerView
android:id="#+id/your id name"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:paddingBottom="?attr/actionBarSize"
app:layout_constraintTop_toBottomOf="#+id/your field" />
1)The View of Recyclerview must be properly constrained. (by ConstraintLayout or any other layout parameters).
2)The Last item occupies the space inside the RecyclerView, hence use Padding. (e.g android:paddingBottom="50dp")
3)Use android:clipToPadding="false" in XML.
Well in my case my ConstraintLayout's layout_height was wrap_content, that's why last item was cutting from bottom. So to resolve this: ConstraintLayout's layout_height should be either fixed or match_parent.
Try using RelativeLayout instead of ConstraintLayout.
It's working for me so it seems a problem with ConstraintLayout specifically.
I'm a bit new to Android development, so I apologize if this question is simple. I have two textviews stacked vertically that I would like to get flush with each other. There's too much whitespace between the two elements:
I have the following activity layout in which I've tried to make the TextViews flush by using a constraint view and setting the margin between the bottom and top to 0dp:

Any help would be appreciated.
I am using this color picker above a guideline and want to align a Text View (and other views) below the guideline and bind them to the width of the color picker by using a ConstraintLayout with these options:
app:layout_constraintRight_toRightOf="#+id/colorPicker"
app:layout_constraintLeft_toLeftOf="#+id/colorPicker"
(The width of the color picker depends on the available height.)
The problem I am facing is that the view seems to be placed exactly below the color picker, however, the content of the view is not adjusted and therefore not shown completely as shown in this picture.
Similar behavior can be reproduced with an ImageView instead of TextView.
A RecyclerView seems to be working, however, the 'list end animation' when reaching the start or end of the list is misplaced.
When using other views instead of this color picker I do not face this issue.
Can anyone explain this behavior and how to fix it?
The complete xml code I am using for this:
<android.support.constraint.ConstraintLayout
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"
tools:context="xxx.xxx.xxx.MainActivity">
<com.rarepebble.colorpicker.ColorPickerView
android:id="#+id/colorPicker"
android:layout_width="wrap_content"
android:layout_height="0dp"
app:layout_constraintTop_toTopOf="parent"
app:layout_constraintBottom_toTopOf="#+id/guideline"
app:layout_constraintLeft_toLeftOf="parent"
app:layout_constraintRight_toRightOf="parent"
/>
<android.support.constraint.Guideline
android:id="#+id/guideline"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
app:layout_constraintGuide_percent="0.60"
android:orientation="horizontal"
/>
<TextView
android:id="#+id/textView"
android:layout_width="0dp"
android:layout_height="wrap_content"
android:text="Hello World! Some chars in this TextView are cut on the right side."
app:layout_constraintTop_toTopOf="#+id/guideline"
app:layout_constraintBottom_toBottomOf="parent"
app:layout_constraintRight_toRightOf="#+id/colorPicker"
app:layout_constraintLeft_toLeftOf="#+id/colorPicker"
/>
</android.support.constraint.ConstraintLayout>
Did you try using LinearLayout? With problems like these, where one view needs to occupy a percentage of the screen, using layout_weight
Solution using LinearLayout
<LinearLayout
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:layout_width="wrap_content"
android:layout_height="match_parent"
android:layout_gravity="center"
android:orientation="vertical">
<com.rarepebble.colorpicker.ColorPickerView
android:id="#+id/colorPicker"
android:layout_width="wrap_content"
android:layout_height="0dp"
android:layout_gravity="center"
android:layout_weight="6"
/>
<FrameLayout
android:layout_width="match_parent"
android:layout_height="0dp"
android:layout_weight="4">
<TextView
android:id="#+id/textView"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_gravity="center"
android:text="Hello World! Some chars in this TextView are cut on the right side." />
</FrameLayout>
</LinearLayout>
Edit based on comments
Something like this should work. You can change the View's visibility to GONE or VISIBLE depending on whether the FloatingActionButton has been tapped or not.
