Add image on top of bottomsheet in Android

How can add image on top of the bottom sheet in Android? See this image
I tried this but it doesn't work. I want the transparency as shown in the image attached.
<?xml version="1.0" encoding="utf-8"?>
<android.support.design.widget.CoordinatorLayout 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="match_parent"
app:layout_behavior="android.support.design.widget.BottomSheetBehavior">
<android.support.design.widget.FloatingActionButton
android:layout_width="wrap_content"
android:layout_height="wrap_content"
app:layout_anchor="#id/myBottomLL"
app:layout_anchorGravity="top|center" />
<LinearLayout
android:id="#+id/myBottomLL"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="vertical">
<ImageView
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:src="#drawable/background" />

For the circular image view:

Just add a transparent View to the top like this.
<?xml version="1.0" encoding="utf-8"?>

Set the theme of the BottomSheetDialogFragment.
You can also add a BottomSheetCallback and decrease the height of the transparent space at the top as you scroll up

RelativeLayout with overlapping views

I need to create a UI design like image below. I have used RelativeLayout, but the top view is hiding behind the CardView. I have tried so many ways, couldn't get it done.
here is my code:
<RelativeLayout
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="150dp"
tools:context=".activity.LoginActivity">
<RelativeLayout
android:layout_width="match_parent"
android:layout_height="match_parent">
<android.support.v7.widget.CardView
android:layout_width="match_parent"
android:layout_height="150dp"
android:elevation="4dp"
android:layout_margin="10dp"
>
</android.support.v7.widget.CardView>
<FrameLayout
android:layout_width="100dp"
android:layout_height="100dp"
android:layout_marginStart="20dp"
android:layout_marginLeft="20dp"
android:background="#drawable/square_items">
<ImageView
android:layout_width="match_parent"
android:layout_height="match_parent"
android:src="#drawable/ic_aboutus"/>
</FrameLayout>
</RelativeLayout>

You need to put ImageView in Cardview so that elevation becomes equal for both. Try this
<?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"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="wrap_content">
<RelativeLayout
android:layout_width="match_parent"
android:layout_height="wrap_content">
<RelativeLayout
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginTop="10dp">
<android.support.v7.widget.CardView
android:layout_width="match_parent"
android:layout_height="150dp"
android:layout_marginStart="10dp"
android:layout_marginTop="10dp"
android:layout_marginEnd="10dp"
android:layout_marginBottom="10dp"
android:elevation="4dp"
android:padding="10dp"
app:cardCornerRadius="6dp">
</android.support.v7.widget.CardView>
</RelativeLayout>
<android.support.v7.widget.CardView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginLeft="20dp">
<ImageView
android:layout_width="100dp"
android:layout_height="100dp"
android:src="#color/red" />
</android.support.v7.widget.CardView>
</RelativeLayout>
</RelativeLayout>

Coordinate Layout in Linear Layout: Component not fixed

As title described, the position of the android logo in rounded image view is not fixed.
App sometimes rendered correctly as what I designed like this:
But sometimes the layout behave in this way:
Below attached my layout .xml code:
<LinearLayout 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">
<android.support.design.widget.CoordinatorLayout
android:layout_width="match_parent"
android:layout_height="275dp">
<ImageView
android:id="#+id/profile_iv_background"
android:layout_width="match_parent"
android:layout_height="200dp"
android:scaleType="fitXY"
android:src="#drawable/profile_bg"/>
<com.makeramen.roundedimageview.RoundedImageView
android:id="#+id/profile_riv_user"
android:layout_width="150dp"
android:layout_height="150dp"
android:scaleType="fitCenter"
android:src="#mipmap/ic_launcher"
app:layout_anchor="#id/profile_iv_background"
app:layout_anchorGravity="bottom|center"
app:riv_border_color="#333333"
app:riv_border_width="2dip"
app:riv_corner_radius="30dip"
app:riv_oval="true"
app:riv_tile_mode="clamp" />
</android.support.design.widget.CoordinatorLayout>
<TextView
android:id="#+id/profile_tv_full_name"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:gravity="center"
android:textSize="30sp"/>
<android.support.v7.widget.RecyclerView
android:id="#+id/profile_rv_info"
android:layout_width="match_parent"
android:layout_height="match_parent" />
Any thoughts would be appreciated.

How to make imageview in cardview align to left

here is my code:
<android.support.v7.widget.CardView
xmlns:app="http://schemas.android.com/apk/res-auto"
android:layout_width="match_parent"
android:layout_height="wrap_content"
app:contentPaddingLeft="#dimen/activity_horizontal_margin"
app:cardUseCompatPadding="true"
app:cardElevation="4dp">
<LinearLayout android:layout_width="match_parent" android:layout_height="wrap_content"
android:orientation="horizontal">
<ImageView android:layout_width="match_parent" android:src="#drawable/ic_open_in_new_black_48dp"
android:layout_height="match_parent"/>
<TextView android:text="in card view" android:layout_gravity="center_vertical"
android:layout_width="match_parent" android:layout_height="wrap_content"/>
</LinearLayout>
</android.support.v7.widget.CardView>
I hope one line with first ImageView and second TextView, but i get:
how to fix it?

You are using match_parent in android:layout_width and android:layout_height for imageview.
Change it to wrap_content.

Use RelativeLayout inplace of LinearLayout and user "alignParentLeft" for ImageView
<android.support.v7.widget.CardView
xmlns:app="http://schemas.android.com/apk/res-auto"
android:layout_width="match_parent"
android:layout_height="wrap_content"
app:contentPaddingLeft="#dimen/activity_horizontal_margin"
app:cardUseCompatPadding="true"
app:cardElevation="4dp">
<RelativeLayout
android:layout_width="match_parent"
android:layout_height="wrap_content">
<ImageView
android:layout_width="match_parent"
android:src="#drawable/ic_open_in_new_black_48dp"
android:layout_height="match_parent"
android:alignParentLeft="true"
/>
<TextView
android:text="in card view"
android:layout_gravity="center_vertical"
android:layout_width="match_parent"
android:layout_height="wrap_content"/>
</RelativeLayout>
</android.support.v7.widget.CardView>

create view over cardview in android

I want to create this layout
this is a cardview (gray view) and imageview(blue view) for that i use this code
<FrameLayout 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="match_parent"
android:background="#color/abc_search_url_text_normal"
android:orientation="vertical">
<android.support.v7.widget.CardView
android:layout_width="match_parent"
android:layout_height="100dp"
android:layout_alignParentBottom="true"
android:layout_gravity="bottom"
android:layout_marginBottom="3dp"
android:paddingTop="5dp"
app:cardBackgroundColor="#color/abc_input_method_navigation_guard">
</android.support.v7.widget.CardView>
<ImageView
android:layout_width="100dp"
android:layout_height="100dp"
android:layout_gravity="bottom"
android:layout_marginBottom="30dp"
android:layout_marginRight="10dp"
android:scaleType="fitXY"
android:src="#drawable/abc_ratingbar_full_material" />
</FrameLayout>
but in result my image view going to back of cardview i try reletivelayout instead of framelayout but same result.

The CardView has by default elevation in API 21+, you can manipulate the elevation to be less than that of the ImageView
<android.support.v7.widget.CardView xmlns:app="http://schemas.android.com/apk/res-auto"
android:layout_width="match_parent"
android:layout_height="wrap_content"
app:cardElevation="1dp"/>
<ImageView
android:id="#+id/image_view_user"
android:layout_width="48dp"
android:layout_height="48dp"
android:elevation="2dp"/>
in Pre 21 you can use
overlayView.bringToFront();
root.requestLayout();
root.invalidate();
This will not work in 21+ if you have different elevation

Just put CardView in other view like in FrameLayout.
Just like below:
<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="wrap_content"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:layout_marginStart="10sp"
android:layout_marginEnd="10sp"
>
<FrameLayout
android:layout_marginTop="15sp"
android:layout_width="match_parent"
android:layout_height="wrap_content">
<android.support.v7.widget.CardView
android:layout_width="match_parent"
android:layout_height="100sp"
app:cardCornerRadius="5sp"
app:cardBackgroundColor="#color/colorPrimary">
<!--other view items -->
</android.support.v7.widget.CardView>
</FrameLayout>
<de.hdodenhof.circleimageview.CircleImageView
android:layout_width="90sp"
android:layout_height="90sp"
app:civ_border_width="2dp"
android:layout_marginStart="10sp"
app:civ_border_color="#color/colorPrimaryDark"
android:id="#+id/profileImg"
android:background="#drawable/ic_if_profle_1055000"
xmlns:app="http://schemas.android.com/apk/res-auto"/>
Screenshot:

Try:
Use a RelativeLayout
Align the ImageView to the parent right/end and add a right/end margin
Align the FAB to the top of the card view and add a negative margin
<RelativeLayout
...>
<CardView
android:id="#+id/cardView"
android:layout_width="match_parent"
android:layout_height="120dp"
/>
<ImageView
android:id="#+id/fab"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentRight="true"
android:layout_alignTop="#id/cardView"
android:layout_marginTop="-32dp"
android:layout_marginRight="20dp"
/>
</RelativeLayout>

Just add elevation to ImageView greater than CardView elevation
<FrameLayout 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="match_parent"
android:background="#color/abc_search_url_text_normal"
android:orientation="vertical">
<androidx.cardview.widget.CardView
android:layout_width="match_parent"
android:layout_height="100dp"
android:layout_alignParentBottom="true"
android:layout_gravity="bottom"
android:layout_marginBottom="3dp"
android:paddingTop="5dp"
app:cardBackgroundColor="#color/white">
</androidx.cardview.widget.CardView>
<ImageView
android:layout_width="100dp"
android:layout_height="100dp"
android:layout_gravity="bottom"
android:layout_marginBottom="30dp"
android:layout_marginRight="10dp"
android:scaleType="fitXY"
android:elevation="8dp"
android:src="#drawable/ic_launcher_background" />

You can wrap CardView in FrameLayout but then the shadow will be cropped.
Set android:clipChildren="false" to fix it
<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="wrap_content"
android:clipChildren="false"
android:layout_height="140dp">
<FrameLayout
android:id="#+id/frameLayout4"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_margin="16dp"
android:clipChildren="false">
<android.support.v7.widget.CardView
app:cardCornerRadius="#dimen/card_radius"
android:layout_width="match_parent"
android:layout_height="match_parent">
</android.support.v7.widget.CardView>
</FrameLayout>
</android.support.constraint.ConstraintLayout>

Another way around it would be to wrap the image view in a card view. Just ensure the background is transparent with height and width wrapping content and it will go on top of the previous card view.
