Android - selectableItemBackground doesn't showed when click on item - android

I have a Recycler view and their items should be clickable. I want that all line do apply the ?selectableItemBackground effect but this does not occurs. The imageview is occupying all the item layout as an background. Why the selectable effect doesn't working as well?
this is my xml file
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="horizontal"
android:layout_width="match_parent"
android:layout_height="?listPreferredItemHeightLarge"
android:background="?selectableItemBackground"
android:descendantFocusability="blocksDescendants">
<FrameLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_centerHorizontal="true">
<ImageView
android:id="#+id/background"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:contentDescription="#string/app_name"
android:src="#drawable/holder"
android:scaleType="centerCrop"
android:focusableInTouchMode="false"/>
<View
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="#color/black"
android:alpha="0.3" />
</FrameLayout>
<br.com.lexsis.pizzahut.presentation.widgets.CustomFontTextView
android:id="#+id/group_name"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_centerVertical="true"
android:background="#android:color/transparent"
style="#style/TextView.EMenu" />
</RelativeLayout>


You can add another RelativeLayout and add android:background="?attr/selectableItemBackground" to it:
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="horizontal"
android:layout_width="match_parent"
android:layout_height="?listPreferredItemHeightLarge"
android:background="?selectableItemBackground"
android:descendantFocusability="blocksDescendants">
<RelativeLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:background="?attr/selectableItemBackground">
<FrameLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_centerHorizontal="true">
<ImageView
android:id="#+id/background"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:contentDescription="#string/app_name"
android:src="#drawable/holder"
android:scaleType="centerCrop"
android:focusableInTouchMode="false"/>
<View
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="#color/black"
android:alpha="0.3" />
</FrameLayout>
<br.com.lexsis.pizzahut.presentation.widgets.CustomFontTextView
android:id="#+id/group_name"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_centerVertical="true"
android:background="#android:color/transparent"
style="#style/TextView.EMenu" />
</RelativeLayout>
</RelativeLayout>
Setting it to the root layout never worked for me.

Android FrameLayout Views Overlapping not Working

I Have the following layout and I need the favorite image to placed on the upper right corner of the itemImage using FrameLayout
<?xml version="1.0" encoding="utf-8"?>
<ScrollView 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=".ItemDetails"
>
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="vertical"
android:paddingBottom="20dp">
<FrameLayout
android:layout_width="match_parent"
android:layout_height="wrap_content">
<ImageView
android:id="#+id/itemdimage"
android:layout_width="match_parent"
android:layout_height="300dp"
android:scaleType="fitEnd"
tools:srcCompat="#mipmap/ic_launcher"
/>
<ImageView
android:id="#+id/favorite"
android:layout_width="50dp"
android:layout_height="50dp"
android:layout_gravity="end"
android:layout_margin="10dp"
tools:srcCompat="#mipmap/ic_launcher_round"
android:elevation="10dp"/>
</FrameLayout>
But the favorite image is never show ?? what is wrong with my layout
Any help will be much appreciated

Maybe this layout will work. I changed tools:srcCompat to android:src. tools: attributes are only visible in AndroidStudio, they are removed from the build.
<?xml version="1.0" encoding="utf-8"?>
<ScrollView xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent">
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="vertical"
android:paddingBottom="20dp">
<FrameLayout
android:layout_width="match_parent"
android:layout_height="wrap_content">
<ImageView
android:id="#+id/itemdimage"
android:layout_width="match_parent"
android:layout_height="300dp"
android:scaleType="fitEnd"
android:src="#mipmap/ic_launcher"/>
<ImageView
android:id="#+id/favorite"
android:layout_width="50dp"
android:layout_height="50dp"
android:layout_gravity="end"
android:layout_margin="10dp"
android:elevation="10dp"
android:src="#mipmap/ic_launcher_round" />
</FrameLayout>
</LinearLayout>
</ScrollView>
The result is this :

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>

How can I remove the outside of view from CardView?

I have the following code:
<?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:layout_width="match_parent"
android:layout_height="match_parent">
<android.support.v7.widget.CardView
android:layout_width="match_parent"
android:layout_height="140dp"
android:layout_margin="10dp"
android:clickable="true"
android:focusable="true"
android:foreground="?attr/selectableItemBackgroundBorderless"
app:cardCornerRadius="50dp">
<RelativeLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:clipChildren="true"
android:clipToPadding="true">
<View
android:layout_width="6dp"
android:layout_height="match_parent"
android:layout_alignParentRight="true"
android:layout_marginRight="15dp"
android:background="#drawable/vertical_line_main" />
</RelativeLayout>
</android.support.v7.widget.CardView>
</LinearLayout>
And get this result:
my result
I want remove view that outside of cardview.
In fact I want have a vertical line with radius. (Remove choosen by green pen)

It's because of your linear layout , why you are not using cardview as parrent view ?

android:layout_width="match_parent"
android:clickable="true"
android:focusable="true"
android:foreground="?attr/selectableItemBackgroundBorderless"
app:cardCornerRadius="50dp">
<RelativeLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:clipChildren="true"
android:clipToPadding="true">
<View
android:layout_width="6dp"
android:layout_height="match_parent"
android:layout_alignParentRight="true"
android:layout_marginRight="15dp"
android:background="#drawable/vertical_line_main" />
</RelativeLayout>
</android.support.v7.widget.CardView>

How to show the toolbar layout only when a song is played (ListView item is clicked)

activity_main2.xml
I want to show the toolbar in the following code only when a listView item is clicked. Otherwise, remain hidden. If I use (View.Invisible) in the Java Code then the layout disappears, yet white space remains in its area. I want the listview to occupy that area.
<?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"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical"
tools:context="com.example.ashutosh.music_player.Main2Activity">
<ImageView
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:id="#+id/catv" />
<ListView
android:id="#+id/track_list_view"
android:layout_width="match_parent"
android:layout_weight="100"
android:layout_height="0dp"
android:overScrollHeader="#drawable/catv1"/>
<android.support.v7.widget.Toolbar
android:id="#+id/bar_player"
android:background="#333333"
android:theme="#style/Theme.AppCompat.Dark.DarkActionBar"
android:layout_width="match_parent"
android:layout_height="50dp"
app:contentInsetStart="0dp">
<ImageView
android:id="#+id/selected_track_image"
android:layout_width="50dp"
android:layout_height="55dp" />
<TextView
android:id="#+id/selected_track_title"
android:paddingLeft="8dp"
android:layout_width="220dp"
android:layout_height="wrap_content" />
<ImageView
android:id="#+id/forward"
android:layout_width="48dp"
android:layout_height="48dp"
android:layout_marginLeft="30dp"/>
<ImageView
android:id="#+id/player_control"
android:layout_gravity="right"
android:layout_width="#dimen/image_size"
android:layout_height="#dimen/image_size" />
</android.support.v7.widget.Toolbar>
</LinearLayout>

Try this,This is what #shijil Said
<?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"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical"
tools:context="com.example.ashutosh.music_player.Main2Activity">
<ImageView
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:id="#+id/catv" />
<ListView
android:id="#+id/track_list_view"
android:layout_width="match_parent"
android:layout_weight="100"
android:layout_height="0dp"
android:overScrollHeader="#drawable/catv1"/>
<android.support.v7.widget.Toolbar
android:id="#+id/bar_player"
android:background="#333333"
android:theme="#style/Theme.AppCompat.Dark.DarkActionBar"
android:layout_width="match_parent"
android:visibility="gone"
android:layout_height="50dp"
app:contentInsetStart="0dp">
<ImageView
android:id="#+id/selected_track_image"
android:layout_width="50dp"
android:layout_height="55dp" />
<TextView
android:id="#+id/selected_track_title"
android:paddingLeft="8dp"
android:layout_width="220dp"
android:layout_height="wrap_content" />
<ImageView
android:id="#+id/forward"
android:layout_width="48dp"
android:layout_height="48dp"
android:layout_marginLeft="30dp"/>
<ImageView
android:id="#+id/player_control"
android:layout_gravity="right"
android:layout_width="#dimen/image_size"
android:layout_height="#dimen/image_size" />
</android.support.v7.widget.Toolbar>
</LinearLayout>
and set programatically
.setVisibility(View.GONE);
.setVisibility(View.VISIBLE);
as needed

Simply use Relative Layout to do so. In this way, if you set the toolbar as invisible, the list view will occupy its position.
