What I'm trying to achive is add CardViews inside my ListView and be able to scroll not just the ListView but the whole view. I tried RecyclerView before but that didn't work for me either.
Here's my idea:
and Scroll the whole thing not just the ListView.
You need to use NestedScrollView.
NestedScrollView is just like ScrollView, but it supports acting as both a nested scrolling parent and child on both new and old versions of Android. Nested scrolling is enabled by default.
Please refer NestedScrollView documentation
Don't forget to add recyclerView.setNestedScrollingEnabled(false); to your RecyclerView.

I have no idea how to fix it -.-
The ListView's height is MATCH_PARENT which constrains it to the height of its parent ViewGroup. You should always define the height of scrollable views like ListView as WRAP_CONTENT so that it can freely expand according to the number of children.
Also it might be a good idea for the parent LinearLayout to be anchored to the top of the RelativeLayout:
android:layout_alignParentTop="true".
Leaving views floating freely in RelativeLayouts may have surprising consequences.
In the XML layout, everything seems perfect. When I used the emulator or real device, the adView is not visible. I tried to give height to adView like 200 dp. Then the adView is visible. But, when I gave the value of wrap_content for the height of the adView, there is a problem. I used LinearLayout and RelativeLayout but the problem is the same. What should I do for this?
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:ads="http://schemas.android.com/apk/res-auto"
android:layout_width="match_parent"

<TextView
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:autoLink="email"
android:gravity="center"
android:selectAllOnFocus="false"
android:text="#string/nav_contact_us_content_mail" />
</LinearLayout>
<com.google.android.gms.ads.AdView
android:id="#+id/adview_id"
android:layout_width="wrap_content"
android:layout_height="wrap_content"

ads:adUnitId="ca-app-pub-3940256099942544/6300978111"></com.google.android.gms.ads.AdView>
</LinearLayout>
Try to put AdView in FrameLayout
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:ads="http://schemas.android.com/apk/res-auto"
android:layout_width="match_parent"

android:orientation="vertical">

android:layout_width="match_parent"

<TextView
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:autoLink="email"
android:gravity="center"
android:selectAllOnFocus="false"
android:text="#string/nav_contact_us_content_mail" />
</LinearLayout>
<FrameLayout
android:layout_width="match_parent"
android:layout_height="wrap_content">
<com.google.android.gms.ads.AdView
android:id="#+id/adview_id"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:clickable="true"
android:focusable="true"
ads:adSize="SMART_BANNER"
ads:adUnitId="ca-app-pub-3940256099942544/6300978111"/>
</FrameLayout>
</LinearLayout>
In the case of LinearLayout, as the weight was set to 1, it took the whole screen when the ad was not yet loaded. However, you should see a warning like the following in your logcat here.
W/Ads: Not enough space to show ad. Needs 320x50 dp, but only has 288x495 dp.
In order to fix the problem, you might consider using a RelativeLayout instead of a LinearLayout like the following.
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:ads="http://schemas.android.com/apk/res-auto"
android:layout_width="match_parent"
android:layout_height="match_parent">
<LinearLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_above="#+id/adview"
android:orientation="vertical"
android:padding="30dp">
<TextView
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_gravity="center_vertical"
android:gravity="center"
android:text="Contact us" />
<TextView
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:autoLink="email"
android:gravity="center"
android:selectAllOnFocus="false"
android:text="Email" />
</LinearLayout>
<LinearLayout
android:id="#+id/adview"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_alignParentBottom="true">
<com.google.android.gms.ads.AdView
android:id="#+id/adview_id"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:clickable="true"
android:focusable="true"
ads:adSize="SMART_BANNER"
ads:adUnitId="ca-app-pub-3940256099942544/6300978111" />
</LinearLayout>
</RelativeLayout>
On the other hand, you might also consider setting up a fixed size for the AdView so that it does not hide when the content is not yet loaded. You can get the sizes of different types of ads for different screen sizes here.
In My Android project I am using RecyclerView inside one layout. Here is the code given below-

Now, for rendering a lot of data when the users scrolls too much fast the screen got hanged. So, I want to slow down the speed of the scrolling.
I have tried the following solution-
How can i control the scrolling speed of recyclerView.smoothScrollToPosition(position)
It works well with horizontal scrolling but when I switch to vertical view then It doesn't work.
Is there any way to solve this?
When I place a RecyclerView as a child of a ScrollView, marginBottom and paddingBottom doesn't work. Setting these values for the parent LinearLayout doesn't affect anything either. It seems that the ScrollView doesn't scroll to the bottom because the ScrollBar doesn't reach the bottom. How can I fix this bug?

DO NOT use ListView inside ScrollView. ListView itself has a scroll property and you don't have to use another ScrollView to make it scroll. Use a LinearLayout instead.
Listview have own scrolling property ,so dont use within scrollview...
thanks
