</RelativeLayout>
in the main activity i typed that but still not working it always crash the application even the <include> tag in the xml file is working
CardView cardView = findViewById(R.id.CARD_VIEW);
View child1 = LayoutInflater.from(this).inflate(R.layout.task_layout,null);
cardView.addView(child1);

Try this...
CardView cardView = findViewById(R.id.id_cardview);
Create an object to your layout
View child1 = LayoutInflater.from(this).inflate(
R.layout.extra, null);
cardView.addView(child1);

How to Control Visibility of items in a Linear Layout in my App?

I have a Vertical linear layout with 2 item. One is a is a customview which is extended from a framelayout and the 2nd one is a textview with a drawable as background. The visibility have to be controlled dynamically from gone to visible.
The issue is that when i change the visibility of the item from gone to visible the order is not coming as i intended. The the second item is below the customview. I want it to come as the 2nd item, below the customview
<?xml version="1.0" encoding="utf-8"?>
<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
xmlns:textureview="http://schemas.android.com/apk/res-auto">
<LinearLayout
android:id="#+id/comment_holder"
android:orientation="vertical"
android:gravity="center_horizontal"
android:layout_width="wrap_content"
android:layout_height="wrap_content">
<com.custom_views.CircularFrameLayout
android:id="#+id/comment_holder_circular_layout"
android:layout_gravity="center_horizontal"
android:layout_width="wrap_content"
android:layout_height="wrap_content">
<ImageView
android:id="#+id/user_avatar"
android:visibility="gone"
android:layout_gravity="center_horizontal"
android:layout_width="#dimen/comment_avatar_width"
android:layout_height="#dimen/comment_avatar_width" />
<com.custom_views.PlaybackTextureView
android:visibility="gone"
android:id="#+id/playback_texture_view"
android:layout_width="match_parent"
android:layout_height="wrap_content"
textureview:isAuthorMode="true"/>
</com.custom_views.CircularFrameLayout>
<LinearLayout
android:visibility="gone"
android:id="#+id/c_holder"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:paddingTop="8dp"
android:paddingBottom="16dp"
android:paddingStart="4dp"
android:paddingEnd="4dp"
android:background="#drawable/chat_bubble_top_arrow_orange"
android:orientation="vertical">
<TextView
android:id="#+id/video_comment_user_name"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:textSize="12sp"
android:textColor="#color/black_50"
android:fontFamily="sans-serif" />
</LinearLayout>
</LinearLayout>
</FrameLayout>
NOTE: I tried adding weight to the custom layout as 1. But it still didnt help.

i use
setNestedScrollingEnabled(false);
for both recycler view.
Any ideas to implement this with a smooth scrolling?

Change ScrollView to NestedScrollView.
In order this to work, you need to have RecyclerView with height wrap_content inside NestedScrollView and you need to set recyclerView.setNestedScrollingEnabled(false) from code.

How i solved this problem is by using a single Recycler view instead of two and setting up the other (1st recycler view in question) recycler view as first item of it.
Now it works perfect and scrolling smoothly.

Android ListView not scrolling inside ViewFlipper

I have A LinearLayout with a GridLayout inside. The GridLayout houses an ImageView, Textviews and then a ListView. I have tried all I can to get the ListView to scroll but it doesn't scroll at all. The LinearLayout ( Main One ) Is housed in a ViewFlipper if that changes anything.
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:id="#+id/singleClub"
android:weightSum="1">
<GridLayout
android:layout_width="match_parent"
android:layout_height="wrap_content">
<ImageView
android:layout_width="fill_parent"
android:layout_height="150dp"
android:id="#+id/mainclub_image"
android:layout_row="0"

android:layout_height="wrap_content"
android:textAppearance="?android:attr/textAppearanceSmall"
android:text="Mon 00:00"
android:id="#+id/mainclub_openingtimes"
android:layout_row="4"
android:layout_column="0"/>
<ScrollView
android:layout_width="wrap_content"
android:layout_height="wrap_content"

</ScrollView>
</GridLayout>
</LinearLayout>
I originally tried it with a Custom Expandable List View which worked but then stopped working later on. Any help would be greatly appreciated.

Remove scrollview outlining ListView and then set the height and width values of list view to match_parent. And Try using a relativelayout.

How to add view below listview

I found few topics here on SO, but they are not what i'm searching. One of them is this one Android ListActivity - how to add a view below the ListView?
I know i can position a View (like button) at the footer of listview. That means desired View will position itself AFTER last view.
I want to know how to position a View at the end of the screen (Just below).
Please check two pictures below:
I want to do this in java code. Any ideas?

try the following code
<ListView
android:id="#android:id/list"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_above="#+id/button1"
>
</ListView>
<Button
android:id="#+id/button1"
style="?android:attr/buttonStyleSmall"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentBottom="true"
android:layout_centerHorizontal="true"
android:text="Button" />

Use a Relative Layout. Set the Height of Listview to the required height. Place the button relative to the listview at the button.
<?xml version="1.0" encoding="utf-8"?>
<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="match_parent"
android:orientation="vertical"
tools:context=".MainActivity" >
<ListView
android:id="#+id/textView1"
android:layout_width="wrap_content"
android:layout_height="200dp"
android:layout_alignParentLeft="true"
android:layout_alignParentTop="true"
android:text="TextView" />
<Button
android:id="#+id/button1"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_alignParentBottom="true"
android:layout_alignParentLeft="true"
android:layout_marginLeft="122dp"
android:text="Button" />
</RelativeLayout>
