I have dialog fragment and i set my custom view to it. I want to make it with round corners and im using CardView for it, but the shape of dialog is still rectangle. Here is my view:
<?xml version="1.0" encoding="utf-8"?>
<androidx.cardview.widget.CardView 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"
android:layout_margin="16dp"
app:cardCornerRadius="40dp">
<androidx.constraintlayout.widget.ConstraintLayout
android:id="#+id/card_cl"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:padding="36dp">
<androidx.appcompat.widget.AppCompatTextView
android:id="#+id/id_tv"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginStart="8dp"
android:textSize="36sp"
app:layout_constraintStart_toStartOf="parent"
app:layout_constraintTop_toTopOf="parent"
android:text="12" />
</androidx.constraintlayout.widget.ConstraintLayout>
</androidx.cardview.widget.CardView>
the result :
Try putting your cardview in a linerlayout or a relative layout if it doesn't work try adding some padding to linerlayout or relativelayout.
This is Bcoz The Card color is similar to the background color. You just need to set elevation.

I am trying to get a card view so that I get a rounded corners image with a text under it but the thing is, when I add the text, since they are both inside of the rounded corners card view, the image is not rounded at the bottom (which is what I need). How would I accomplish that?
This is the layout:
<?xml version="1.0" encoding="utf-8"?>
<androidx.cardview.widget.CardView
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:layout_width="300dp"
android:layout_height="wrap_content"
android:layout_margin="16dp"
app:cardCornerRadius="16dp">
<LinearLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical">
<ImageView
android:id="#+id/iv_news"
android:layout_width="300dp"
android:layout_height="200dp"
android:src="#drawable/background_shape"
android:scaleType="centerCrop" />
<TextView
android:id="#+id/tv_title"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:text="#string/news_title"
android:textColor="#color/black"
android:textAppearance="?android:attr/textAppearanceMedium"
android:textAlignment="center"
android:layout_marginTop="5dp"/>
</LinearLayout>
</androidx.cardview.widget.CardView>
The image (I need the bottom corners of the image also rounded):
Try to put this code in your "#drawable/background_shape". Just tried it and it all working fine.
<?xml version="1.0" encoding="UTF-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android">
<corners android:bottomLeftRadius="20dp" android:bottomRightRadius="20dp"/>
</shape>
The problem is the TextView is overlaying the card radius. To fix that add padding to the text view or to the card and that should solve it.
The answer marked as correct, is not clean: Adds an unnecessary drawable, the card view already has a corner radius property, making the child implement round corners as well defeat the purpose of such attribute.
Also, try to use material card view: <com.google.android.material.card.MaterialCardView/>. You might not needed it now but it has more customizations.
If you only need a circular image in that case you need to add only ImageView inside CardView, and which looks like this:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical"
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto">
<androidx.cardview.widget.CardView
android:layout_width="300dp"
android:layout_height="wrap_content"
android:layout_margin="16dp"
app:cardCornerRadius="16dp">
<ImageView
android:id="#+id/iv_news"
android:layout_width="300dp"
android:layout_height="200dp"
android:src="#drawable/background_shape"
android:scaleType="centerCrop" />
</androidx.cardview.widget.CardView>
<TextView
android:id="#+id/tv_title"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:text="#string/news_title"
android:textColor="#color/black"
android:textAppearance="?android:attr/textAppearanceMedium"
android:textAlignment="center"
android:layout_marginTop="5dp"/>
</LinearLayout>
i looking to align to the top of screen a simple image with ConstraintLayout. I just tried:
<ImageView
android:id="#+id/imagecookie"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:src="#drawable/before_cookie"
app:layout_constraintTop_toBottomOf="parent" />
The pict is positionning in the middle of screen.
Any help?
Thanks
You're setting the top of your ImageView to the bottom of the parent (ConstraintLayout), you need to set it to the top
EDIT Sample with the whole layout
<?xml version="1.0" encoding="utf-8"?>
<androidx.constraintlayout.widget.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"
android:background="#color/colorPrimary"
tools:context=".MainActivity">
<ImageView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:src="#mipmap/ic_launcher"
app:layout_constraintEnd_toEndOf="parent"
app:layout_constraintStart_toStartOf="parent"
app:layout_constraintTop_toTopOf="parent" />
</androidx.constraintlayout.widget.ConstraintLayout>
Result
Thank for you time and help but it still not positioned at the top of screen.
i put my picture at the top of the screen (and middle horizontal) with:
<ImageView
android:id="#+id/imagecookie"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:src="#drawable/suzuki"
app:layout_constraintEnd_toEndOf="parent"
app:layout_constraintStart_toStartOf="parent"
app:layout_constraintTop_toTopOf="parent" />
I'm trying to accomplish the following:
enter image description here
The gray part is the background of the activity and the white part is a horizontal LinearLayout. I want to create the spinner overlapping the top border of the LinearLayout but everything I can do is put it inside the layout or on top of it. Is there a way to accomplish this? or a workaround?
We can use ConstraintLayout for this. We need to use combinations of two properties
layout_constraintTop_toBottomOf
layout_constraintBottom_toBottomOf
This will center the Button or any other View
Example:
<?xml version="1.0" encoding="utf-8"?>
<androidx.constraintlayout.widget.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">
<View
android:id="#+id/topView"
android:layout_width="match_parent"
android:layout_height="100dp"
android:background="#android:color/holo_orange_dark"
app:layout_constraintTop_toTopOf="parent"
app:layout_constraintStart_toStartOf="parent"
android:orientation="horizontal" />
<View
android:id="#+id/bottomView"
android:layout_width="match_parent"
android:layout_height="100dp"
app:layout_constraintTop_toBottomOf="#id/topView"
android:background="#android:color/holo_green_light"
android:orientation="horizontal" />
<com.google.android.material.button.MaterialButton
android:text="Button"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
app:layout_constraintTop_toBottomOf="#id/topView" // this
app:layout_constraintBottom_toBottomOf="#id/topView" // and this is important, it aligns the view to the top view
app:layout_constraintStart_toStartOf="parent"
app:layout_constraintEnd_toEndOf="parent"/>
</androidx.constraintlayout.widget.ConstraintLayout>
Result:
I know this question has been asked many times. However all the answers I have tried to find have failed me. I want the textview to appear on top of the constraint layout but every time I try to run the application I just see the web view vidged which is connected to the constraint layout.
The last solution I tried was to reduce elevation of the layout to 1dp and increase elevation of the TextView to 2dp.
<?xml version="1.0" encoding="utf-8"?>
<androidx.constraintlayout.widget.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:background="#drawable/green_border_background" android:elevation="1dp">
<TextView android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:gravity="top"
app:layout_constraintBottom_toBottomOf="parent"
app:layout_constraintEnd_toEndOf="parent"
app:layout_constraintStart_toStartOf="parent"
app:layout_constraintTop_toTopOf="parent"
android:elevation="2dp"
android:id="#+id/textView2"
tools:text="0"
android:textSize="30sp"
/>
At the moment I do not care if the textview is centered, vertically below or vertically above the layout. I just want it to be visible. It is under the layout (Z vise) and thereby invisible. Elevation is the problem I am facing.
<?xml version="1.0" encoding="utf-8"?>
<androidx.constraintlayout.widget.ConstraintLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
xmlns:app="http://schemas.android.com/apk/res-auto"
>
<TextView
android:textSize="25sp"
android:layout_marginStart="50dp"
android:text="Title"
app:layout_constraintStart_toStartOf="parent"
app:layout_constraintTop_toTopOf="parent"
app:layout_constraintEnd_toEndOf="parent"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
/>
</androidx.constraintlayout.widget.ConstraintLayout>
This code place the TextView on the top of the ConstraintLayout
Just check the ConstraintLayout.
Read the "Adjust the constraint bias" part, try to set the
app:layout_constraintVertical_bias="0"
I have the following xml for a cardview:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical" android:layout_width="match_parent"
android:layout_height="match_parent" android:padding="2dp">
<!-- A CardView that contains a TextView -->
<android.support.v7.widget.CardView
xmlns:card_view="http://schemas.android.com/apk/res-auto"
android:id="#+id/card_view"
android:layout_gravity="center"
android:layout_width="200dp"
android:layout_height="wrap_content"
card_view:cardCornerRadius="0dp">
<FrameLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:padding="5dp">
<TextView
android:id="#+id/info_text"
android:layout_width="match_parent"
android:layout_height="match_parent" />
</FrameLayout>
</android.support.v7.widget.CardView>
</LinearLayout>
Which results in these shadows which have no shading on the bottom at all
But I am trying to get something like this shadow, that more nicely surrounds the whole card.
I've tried changing the elevation to no avail, and searching on this issue seems to bring up nothing but people with no shadows at all issues which is not my case.
How can I get the shadows right?
Thanks.
You need to add this xml property in your card view
app:cardUseCompatPadding="true"
Adding clipChildren="false" to the parent LinearLayout should also work.
set elevation using card_view:cardElevation property
I was having the same problem until I remembered that if the parent is wrapping its content, then it will not wrap the shadow, so I gave the parent a bigger size than the child that way it will include the child and the shadow of the child

add these lines in your cardView
android:layout_marginTop="5dp"
android:layout_marginBottom="5dp"
