CardView custom background - android

I try to add custom background in my CardView.This is my source
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:id="#+id/item_container"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:background="#ff00"
android:orientation="vertical">
<android.support.v7.widget.CardView xmlns:card_view="http://schemas.android.com/apk/res-auto"
android:layout_width="match_parent"
android:layout_height="wrap_content"
card_view:cardCornerRadius="12dp"
card_view:cardElevation="12dp"
card_view:cardPreventCornerOverlap="false"
card_view:contentPadding="0dp"
android:layout_margin="16dp"
>
<LinearLayout
android:layout_width="match_parent"
android:layout_height="80dp"
android:orientation="vertical">
<RelativeLayout
android:layout_width="match_parent"
android:layout_height="40dp"
android:background="#cccccc">
</RelativeLayout>
</LinearLayout>
</android.support.v7.widget.CardView>
As you can see into Cardview i have LinearLayout and RelativieLayout.RelativeLayout's background color is #cccccc,but cornerradius and elevetion not working with custom background color.(please see my picture)
How i can solve my problem?


Your Linear Layout inside CardView is overlapping your cardview's top corners due to fix height given to linear layout. When giving height to cardview and making linear layout match_parent, and giving contentPadding in cardview makes corners visible.
Here is the code and screenshot.
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:id="#+id/item_container"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:background="#ff00"
android:orientation="vertical">
<android.support.v7.widget.CardView xmlns:card_view="http://schemas.android.com/apk/res-auto"
android:layout_width="match_parent"
android:layout_height="80dp"
card_view:cardCornerRadius="12dp"
card_view:cardElevation="12dp"
card_view:cardPreventCornerOverlap="true"
card_view:contentPadding="2dp"
android:layout_margin="16dp">
<LinearLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical">
<RelativeLayout
android:layout_width="match_parent"
android:layout_height="40dp"
android:background="#cccccc">
</RelativeLayout>
</LinearLayout>
</android.support.v7.widget.CardView>
</LinearLayout>

As shown in above code. I have also added fillViewport to true, still it's not working. CardView works fine when i remove the scroll view but i am not able to scroll.
How do i solve this issue?

You can use android:layout_gravity="center" for the linear layout that contains imageview and change scale type to centerInside or fitCenter
<LinearLayout
android:orientation="vertical"
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=".MainActivity">
<androidx.cardview.widget.CardView
android:layout_margin="10dp"
android:layout_width="match_parent"
android:layout_height="match_parent">
<ScrollView
android:fillViewport="true"
android:layout_width="match_parent"
android:layout_height="match_parent">
<LinearLayout
android:orientation="vertical"
android:padding="10dp"
android:layout_gravity="center"
android:layout_width="match_parent"
android:layout_height="wrap_content">
<ImageView
android:layout_marginTop="10dp"
android:id="#+id/orbitPostSharedImg"
android:layout_gravity="center_horizontal"
android:scaleType="centerInside"
android:src="#drawable/rabindranath_tagore"
android:layout_width="match_parent"
android:layout_height="wrap_content"/>
</LinearLayout>
</ScrollView>
</androidx.cardview.widget.CardView>
</LinearLayout>

change ImageView scaleType from centerCrop to centerInside

add ripple in cardview of recycler view for api more than 19?

I tried the following code but it doesn't show any effect, I implemented the same method for recycler list view then it worked but for this, it is not working.
I want to make a round ripple and should fit card view.
Recycler view for card view:
<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:background="#color/bg"
android:orientation="vertical">
<android.support.v7.widget.RecyclerView
android:id="#+id/rv_list"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:focusable="true"
android:clickable="true"
android:background="?android:attr/selectableItemBackground"/>
</LinearLayout>
CARD VIEW:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:card_view="http://schemas.android.com/apk/res-auto"
xmlns:tools="http://schemas.android.com/tools"

Align a LinearLayout at the bottom of a RelativeLayout

I have these nested layouts and i want to put a LinearLayout anchored to the bottom (internally) of the first RelativeLayout but i don't know how to do it. Can someone help me? I want something like this: https://imgur.com/eCCYS8Q
<RelativeLayout 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="#fff"
tools:context=".MainActivity">
<LinearLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_alignParentStart="true"
android:layout_alignParentTop="true"
android:orientation="vertical"
android:weightSum="1">
<RelativeLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_weight="0.65"
android:background="#drawable/background_gradient">
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content">
</LinearLayout>
</RelativeLayout>
<RelativeLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_weight="0.35">
</RelativeLayout>
</LinearLayout>
</RelativeLayout>

To make layout_weight work properly set android:layout_height="0dp" for both relative layouts
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical"
android:weightSum="1">
<RelativeLayout
android:layout_width="match_parent"
android:layout_height="0dp"
android:layout_weight="0.65"
android:background="#color/colorPrimary">
<LinearLayout
android:layout_width="match_parent"
android:layout_alignParentBottom="true"
android:layout_marginTop="10dp"
android:layout_marginStart="10dp"
android:layout_marginEnd="10dp"
android:layout_height="match_parent"
android:background="#color/colorAccent">
</LinearLayout>
</RelativeLayout>
<RelativeLayout
android:layout_width="match_parent"
android:layout_height="0dp"
android:layout_weight="0.35"
android:background="#color/colorPrimaryDark">
</RelativeLayout>
</LinearLayout>
change 10dp to whatever suits you.
I set the colors just to distinguish the layouts

If you want to align a view to the bottom of a relative layout you need to use
android:layout_alignParentBottom="true"
in the view that is going to be stuck at the bottom of the relative

Align LinearLayout to the bottom using id.
take the id of relative layout and then align LinearLayout to the bottom at the end of relative layout id.

Since you need weighttoo in your UI so This will work for you
<LinearLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_alignParentStart="true"
android:layout_alignParentTop="true"
android:orientation="vertical"
android:weightSum="1">
<RelativeLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_weight="0.65"
android:background="#drawable/background_gradient">
<LinearLayout
android:layout_width="match_parent"
android:layout_alignParentBottom="true"
android:layout_height="wrap_content">
</LinearLayout>
</RelativeLayout>
<RelativeLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_weight="0.35">
</RelativeLayout>
</LinearLayout>

card_view:cardUseCompatPadding="true">
<RelativeLayout
android:layout_width="360dp"
android:layout_height="wrap_content"
android:background="#fff">...
Can sb help me?Thanks in advance

Use CardView as your Parent layout in item layout as follows -
<?xml version="1.0" encoding="utf-8"?>
<android.support.v7.widget.CardView xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:layout_margin="6dp"
app:cardElevation="#dimen/dimen4"
app:cardBackgroundColor="#fff"
android:id="#+id/job_post"
app:cardCornerRadius="3dp"
android:layout_height="wrap_content">
<RelativeLayout
android:layout_width="match_parent"
android:layout_margin="2dp"
android:layout_height="wrap_content"
android:background="#fff">
<TextView
android:id="#+id/textView3"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentTop="true"
android:layout_centerHorizontal="true"
android:text="TextView" />
</RelativeLayout>
</android.support.v7.widget.CardView>
Give width of RecyclerView match_parent in your activity or fragment.
Thanks , I hope its work for you

You can use card view in linear layout and then set margin like below:-
<LinearLayout android:layout_height="match_parent"
android:layout_width="match_parent"
android:orientation="vertical"
android:background="#color/blue"
xmlns:android="http://schemas.android.com/apk/res/android" >
<android.support.v7.widget.CardView
android:layout_width="match_parent"
android:layout_margin="20dp"
android:layout_height="match_parent">
<TextView
android:layout_width="match_parent"
android:layout_height="match_parent"
android:gravity="center"
android:text="Cardview Demo"/>
</android.support.v7.widget.CardView>
</LinearLayout>
I hope it will help you and you can set margin of cardview or your required width to cardview

FAB on RelativeLayout like in CoordinatorLayout

I want to made view looking like this.
I have a problem with FAB placement. I want to place it on the center and bottom of RelativeLayout.

You can use FrameLayout as a container like this :
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/activity_main"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:gravity="center_horizontal"
android:orientation="vertical">
<FrameLayout
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginTop="50dp"
android:background="#ccc"
android:orientation="vertical">
<!--MARGIN WILL BE HALF OF HEIGHT OF FAB-->
<RelativeLayout
android:id="#+id/relative2"
android:layout_width="200dp"
android:layout_height="200dp"
android:layout_gravity="bottom"
android:layout_marginBottom="25dp"
android:background="#color/colorPrimary"></RelativeLayout>
<View
android:id="#+id/view1"
android:layout_width="50dp"
android:layout_height="50dp"
android:layout_gravity="bottom|center_horizontal"
android:background="#color/colorAccent" />
</FrameLayout>
</LinearLayout>
