how to add switch inside toolbar in android?

I am developing android app and I want to add switch inside toolbar it is not showing
below is my xml
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/drawer_layout"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical">
<androidx.appcompat.widget.Toolbar
android:layout_width="match_parent"
android:layout_height="wrap_content">
<Switch
android:id="#+id/switch1"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:text="Switch" />
</androidx.appcompat.widget.Toolbar>
<androidx.recyclerview.widget.RecyclerView
android:id="#+id/recycler_view"
android:layout_width="match_parent"
android:layout_height="match_parent">
</androidx.recyclerview.widget.RecyclerView>
</LinearLayout>
following screen current ui
I want to know how to achieve that kind of ui what I have to do

Simply Change AppTheme to NoActionBar from styles.xml
styles.xml
<resources>
<!-- Base application theme. -->
<style name="AppTheme" parent="Theme.AppCompat.Light.NoActionBar">
<!-- Customize your theme here. -->
<item name="colorPrimary">#color/colorPrimary</item>
<item name="colorPrimaryDark">#color/colorPrimaryDark</item>
<item name="colorAccent">#color/colorAccent</item>
</style>
</resources>
Now run your app, switch will show on the top in Toolbar.

You need to use custom toolbar which you are already using in your xml file but you need to remove your default toolbar by calling getSupportActionBar().hide(); in activity onCreate(). and set the color of toolbar in xml
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/drawer_layout"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical">
<androidx.appcompat.widget.Toolbar
android:elevation="#dimen/margin_large"
android:background="#color/colorPrimaryDark"
android:layout_width="match_parent"
android:layout_height="wrap_content">
<Switch
android:id="#+id/switch1"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:text="Switch" />
</androidx.appcompat.widget.Toolbar>
<androidx.recyclerview.widget.RecyclerView
android:id="#+id/recycler_view"
android:layout_width="match_parent"
android:layout_height="match_parent">
</androidx.recyclerview.widget.RecyclerView>

Find the file named styles.xml in your res folder.
You should have defined a theme for your project which looks something like below code
<style name="AppTheme" parent="Theme.AppCompat.Light.DarkActionBar">
<!-- Customize your theme here. -->
<item name="colorPrimary">#color/text_description</item>
<item name="colorPrimaryDark">#color/black</item>
<item name="colorAccent">#color/theme_teal</item>
</style>
Here, colorPrimary defines the color of your actionBar. This color must have been set to blue acc to the screenshot.
Try changing the colorPrimary value to the desired color that you want.

Change style.xml:
<item name="colorPrimary">#color/colorPrimary</item>
to :
<item name="colorPrimary">#android:color/holo_red_dark</item>

Fixed Footer in Android API 22 (Android 5.1 (Lollipop))

I am new to Android and trying to develop an app with Android API 22. I am not able to get a fixed footer. How to make the footer fixed with scrollable content in the middle of the activity? What are attributes to set and how?
I have solution like - setting 'android:layout_alignParentBottom="true"' which might work for previous API levels but now obsolete.

Try android:layout_gravity="bottom", it works in my app.

I usually do it like this...
layout.xml
<RelativeLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent">
<ScrollView
android:layout_width="match_parent"
android:layout_height="match_parent"
android:paddingLeft="16dp"
android:paddingRight="16dp">
<LinearLayout
android:orientation="vertical"
android:layout_width="match_parent"
android:layout_height="wrap_content">
<!-- The content: this is scrollable -->
</LinearLayout>
</ScrollView>
<LinearLayout
android:id="#+id/footer"
style="#style/Footer"
android:layout_alignParentBottom="true"
android:layout_alignParentRight="true"
android:layout_alignParentLeft="true"
android:layout_alignParentStart="true"
android:layout_alignParentEnd="true">
<!-- Stuff to go in your footer -->
</LinearLayout>
</RelativeLayout>
styles.xml
<style name="Footer" parent="Widget.AppCompat.ButtonBar" >
<item name="android:background">#android:color/white</item>
<item name="android:gravity">center_vertical|end</item>
<item name="android:layout_height">wrap_content</item>
<item name="android:layout_width">match_parent</item>
<item name="android:padding">4dp</item>
</style>
v21/styles:
<style name="AppTheme.LinearLayout.Footer" parent="Widget.AppCompat.ButtonBar" >
<item name="android:background">#android:color/white</item>
<item name="android:gravity">center_vertical|end</item>
<item name="android:layout_height">wrap_content</item>
<item name="android:layout_width">match_parent</item>
<item name="android:padding">4dp</item>
<item name="android:elevation">4dp</item>
</style>
This creates a nice-looking footer, with elevation on Lollipop+ devices.

You want to do something very similar to this:
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
>
<ScrollView
android:layout_above="#+id/footer"
android:layout_width="match_parent"
android:layout_height="match_parent"
>
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="vertical"
>
</LinearLayout>
</ScrollView>
<LinearLayout
android:id="#+id/footer"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="horizontal"
>
</LinearLayout>
</RelativeLayout>

Android Material CardView with full screen image on Cardview

i need to do this :
http://developer.android.com/design/material/images/card_travel.png
so i create and add the dependency to the project and here is my activity main code:
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/feed_detail"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical">
<android.support.v7.widget.CardView
android:layout_height="wrap_content"
android:layout_width="match_parent"
android:layout_margin="6dp">
<ImageView
android:layout_width="100dp"
android:layout_height="50dp"
android:src="#drawable/ic"/>
<TextView
style="#style/TextAppearance.AppCompat.Caption"
android:textColor="#555"
android:layout_margin="3dp"
android:gravity="end"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:text="Detail"/>
</android.support.v7.widget.CardView>
</LinearLayout>
so, how we can do this like below picture:?

Cheers!

What you're looking for is a translucent status bar. When you have this configured you're able achieve this effect. Make also sure to remove the actionbar as I do in my example down below, otherwise you'll have to make it transparent.
Change your v21/themes.xml file to this:
<style name="Theme.MyTheme" parent="Theme.AppCompat.Light.NoActionBar">
<item name="android:statusBarColor">#android:color/transparent</item>
<item name="android:windowDrawsSystemBarBackgrounds">true</item>
<item name="android:windowTranslucentStatus">true</item>
</style>
Then add android:fitsSystemWindows="true" to your LinearLayout.
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/feed_detail"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical"
android:fitsSystemWindows="true">

Navigation Drawer not occure on Status Bar

Actually i am trying to do navigation drawer but i want it on status bar not below it i put all kind of code to make it transparent but still don't work
My xml layout is like
<android.support.v4.widget.DrawerLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:id="#+id/drawer_layout"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:fitsSystemWindows="true"
android:elevation="7dp">
<LinearLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical">
<android.support.v7.widget.Toolbar xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/tool_bar"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:background="#color/actionbar_color"
app:contentInsetEnd="0dp"
app:contentInsetStart="0dp"></android.support.v7.widget.Toolbar>
<FrameLayout
android:id="#+id/content_fragment"
android:layout_width="match_parent"
android:layout_height="match_parent" />
</LinearLayout>
<LinearLayout
android:id="#+id/drawer_Linearlayout"
android:layout_width="260dp"
android:layout_gravity="start|top"
android:layout_height="match_parent"
android:orientation="vertical">
<ImageView
android:layout_width="match_parent"
android:layout_height="168dp"
android:scaleType="fitXY"
android:src="#drawable/navigation_img"
android:id="#+id/mytext"/>
<ListView
android:id="#+id/navdrawer"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:paddingLeft="5dp"
android:layout_below="#+id/mytext"
android:layout_gravity="start|bottom"
android:background="#FFFFFF"
android:choiceMode="singleChoice"
android:divider="#android:color/transparent"
android:dividerHeight="0dp"
android:listSelector="#drawable/list_selector"
android:paddingTop="5dp"></ListView>
</LinearLayout>
</android.support.v4.widget.DrawerLayout>
My Theme is for v-21
<style name="AppThemes" parent="Theme.AppCompat.Light.NoActionBar">
<!-- Customize your theme here. -->
<item name="android:windowTranslucentStatus">true</item>
<item name="windowActionModeOverlay">true</item>
<item name="android:windowDrawsSystemBarBackgrounds">true</item>
<item name="android:statusBarColor">#android:color/transparent</item>
<item name="colorPrimary">#color/actionbar_color</item>
<item name="colorPrimaryDark">#color/alert_normal</item>
<item name="colorAccent">#color/actionbar_color</item>
<item name="drawerArrowStyle">#style/DrawerArrowStyle</item>
</style>
When i remove LinearLayout and ImageView it work fine but
i want imageview inside DrawerLayout but actually it supports only 2 child elements so i have to use LinearLayout
Please suggest me way to do that way.

I got solution for such layout.
Sorry for posting late. I just have to make a little change in xml just like that.
<?xml version="1.0" encoding="utf-8"?>
<android.support.v4.widget.DrawerLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/drawer_layout"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:elevation="7dp">
<LinearLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical">
<include layout="#layout/app_bar"></include>
<FrameLayout
android:id="#+id/content_fragment"
android:layout_width="match_parent"
android:layout_height="match_parent" />
</LinearLayout>
<LinearLayout
android:id="#+id/drawer_Linearlayout"
android:layout_width="260dp"
android:layout_gravity="left|start"
android:layout_height="match_parent"
android:orientation="vertical">
<ImageView
android:layout_width="match_parent"
android:layout_height="168dp"
android:scaleType="fitXY"
android:src="#drawable/navigation_img"
android:id="#+id/mytext" />
<ListView
android:id="#+id/navdrawer"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:paddingLeft="5dp"
android:layout_below="#+id/mytext"
android:layout_gravity="start|bottom"
android:background="#FFFFFF"
android:choiceMode="singleChoice"
android:divider="#android:color/transparent"
android:dividerHeight="0dp"
android:listSelector="#drawable/list_selector"
android:paddingTop="5dp"></ListView>
</LinearLayout>
</android.support.v4.widget.DrawerLayout>
And also make your theme style for v-21 like that.
<!-- Base application theme. -->
<style name="AppThemes" parent="Theme.AppCompat.Light.NoActionBar">
<!-- Customize your theme here. -->
<item name="android:windowTranslucentStatus">true</item>
<item name="colorPrimary">#color/actionbar_color</item>
<item name="android:textColor">#color/myNavigationColor</item>
<item name="android:statusBarColor">#android:color/transparent</item>
<item name="titleTextStyle">#style/ActionBarTitleText</item>
<item name="colorPrimaryDark">#color/actionbar_primary_color</item>
<item name="colorAccent">#color/actionbar_color</item>
<item name="drawerArrowStyle">#style/DrawerArrowStyle</item>
<item name="android:actionOverflowButtonStyle">#style/MyActionButtonOverflow</item>
</style>
and normal theme style is like
<style name="AppThemes" parent="Theme.AppCompat.Light.NoActionBar">
<!-- Customize your theme here. -->
<item name="colorPrimaryDark">#color/actionbar_primary_color</item>
<item name="colorPrimary">#color/actionbar_color</item>
<item name="windowActionModeOverlay">true</item>
<item name="android:textColor">#color/myNavigationColor</item>
<item name="drawerArrowStyle">#style/DrawerArrowStyle</item>
<item name="android:actionOverflowButtonStyle">#style/MyActionButtonOverflow</item>
</style>
Hope if you get stuck in such situation, these will be the solution for you.

Try adding these lines to your android:id="#+id/drawer_Linearlayout"
The layout gravity should start from left to right, and make it fit by setting the android:fitsSystemWindowsattribute to true.
<LinearLayout
android:id="#+id/drawer_Linearlayout"
android:layout_width="260dp"
android:layout_gravity="left|start"
android:fitsSystemWindows="true"
android:layout_height="match_parent"
android:orientation="vertical">
