How to align buttons side by side in scroll view?

I just started using android studio.. I am trying to align ImageButtons inside a scroll view side by side, but i cannot put them side by side, neither can i resize them from the left side. How do i align them side by side?
I already tried the solution given in one of the answers: Aligning TextView Side By Side Inside A ScrollView Inside a Linear Layout but it didn't work

I want the Image buttons to be side by side, but they are in rows, on top of each other.. but it shows like the one in picture:

Thanks.

You have to change the orientation in LinearLayout from vertical to horizontal.
<LinearLayout
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:orientation="horizontal">

Try this
<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">
<LinearLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
app:layout_constraintEnd_toEndOf="parent"
app:layout_constraintStart_toStartOf="parent">
<ScrollView
android:layout_width="match_parent"
android:layout_height="match_parent">
<LinearLayout
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:orientation="horizontal"
//The question you mentioned can be obtained by using weightSum
android:weightSum="15">
//replace src ic_launcher_background by your drawable source.
<ImageButton
android:id="#+id/titlee"
android:layout_width="0dp"
android:layout_weight="5"
android:layout_height="wrap_content"
android:background="#android:color/black"
android:src="#drawable/ic_launcher_background" />
<ImageButton
android:id="#+id/imageButton8"
android:layout_width="0dp"
android:layout_weight="5"
android:layout_height="wrap_content"
android:background="#android:color/black"
android:src="#drawable/ic_launcher_background" />
<ImageButton
android:id="#+id/imageButton9"
android:layout_width="0dp"
android:layout_weight="5"
android:background="#android:color/black"
android:layout_height="wrap_content"
android:src="#drawable/ic_launcher_background"/>
</LinearLayout>
</ScrollView>
</LinearLayout>
Try this and let me know. Happy coding.

</ScrollView>
</LinearLayout>
Try this if you still find any issue, let me know.

Show the Image buttons to be side by side, and in rows.
Change the orientation of LinearLayout from vertical to horizontal.
Please try below code:
<?xml version="1.0" encoding="utf-8"?>
<android.support.constraint.ConstraintLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"

android:layout_height="match_parent"
app:layout_constraintEnd_toEndOf="parent"
app:layout_constraintStart_toStartOf="parent">
<ScrollView
android:layout_width="match_parent"
android:layout_height="match_parent">
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="horizontal">
<ImageButton
android:id="#+id/titlee"
android:layout_weight=".3"
android:layout_width="0dp"
android:layout_height="116dp"
android:background="#android:color/black"
app:srcCompat="#drawable/stars_one"
android:layout_margin="4dp"/>
<ImageButton
android:layout_weight=".4"
android:id="#+id/imageButton8"
android:layout_width="0dp"
android:layout_height="116dp"
android:background="#android:color/black"
app:srcCompat="#drawable/stars_one"
android:layout_margin="4dp"/>
<ImageButton
android:layout_weight=".3"
android:id="#+id/imageButton9"
android:layout_width="0dp"
android:layout_height="116dp"
app:srcCompat="#drawable/stars_one"
android:layout_margin="4dp"/>
</LinearLayout>
</ScrollView>
</RelativeLayout>
</android.support.constraint.ConstraintLayout>
The output of above code is like:

The Background of the recyclerview is a simple image, that is supposed to show through the linear layouts. But unfortunately, this is the result:
So, as you can see, the background is displayed just right but the supposed to be transparent layout for the cardview i am using here is some wired black.
I can make it whatever color I want, but with:
android:background="#android:color/transparent"
it just gets black.
Can anyone help me here?
Thanks you! :)

You can use
app:cardBackgroundColor="#android:color/transparent"

You have to change your CardView background color. you can use
app:cardBackgroundColor="#android:color/transparent"
Instead of
android:background="#android:color/transparent"
Like :
<android.support.v7.widget.CardView 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"
app:cardBackgroundColor="#android:color/transparent">
<!-- Your view design -->
</android.support.v7.widget.CardView>

... turns out CARDVIEWS do not have such attribute. Making the rootlayout a linearlayout solved this issue.

Android:ScrollView will not scroll at all

Here is my code, I have looked at and tried all of the solutions that other people were given and still it does not scroll? Nothing happens when I try to scroll though the ScrollView. I also tried replacing the ScrollView with 'android:scrollbars = "horizontal"'
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"

android:layout_width="match_parent"
android:layout_height="wrap_content"

How do I get an imageView and textview to both fill the layout when setting bitmap programmatically?

What I want is for qrcodetext to fit and display all the text in qrcode_layout and have qrimageView to fill the rest of qrcode_layout? But my layout below has the entire qrimageView cover qrcode_layout. I tried a bunch of other variations but without success.
Here is what it looks like.
Here is what I want it to look like.
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical" android:layout_width="match_parent"
android:layout_height="match_parent">
<LinearLayout
android:layout_height="match_parent"
android:layout_width="match_parent"
android:orientation="vertical"
android:id="#+id/qrcodelayout">
<LinearLayout
android:layout_height="wrap_content"
android:layout_width="wrap_content"
android:orientation="vertical">
<ImageView
android:layout_width="match_parent"
android:layout_height="match_parent"
android:id="#+id/qrimageView"
android:layout_gravity="center_horizontal"
android:layout_marginTop="8dp" />
</LinearLayout>
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:id="#+id/qrcodetext"
android:gravity="center"
android:layout_gravity="center_horizontal"
android:layout_marginTop="4dp" />
</LinearLayout>
<LinearLayout
android:layout_width="match_parent"
android:layout_height="match_parent">
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"/>
</LinearLayout>
</RelativeLayout>

Use following code. Align your textview to bottom and then align your Qrcode Image above text:
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical" android:layout_width="match_parent"
android:layout_height="match_parent">
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:id="#+id/qrcodetext"
android:gravity="center"
android:layout_alignParentBottom="true"
android:layout_marginTop="4dp" />
<ImageView
android:layout_width="match_parent"
android:layout_height="match_parent"
android:id="#+id/qrimageView"
android:layout_gravity="center_horizontal"
android:layout_above="#id/qrcodetext"
android:layout_alignParentTop="true"
android:layout_marginTop="8dp" />
</RelativeLayout>

I think what i have understand you want is below: Plz check and tell me:
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical" android:layout_width="match_parent"

android:layout_width="match_parent"
android:orientation="vertical"
android:id="#+id/qrcodelayout">

android:layout_height="50dp"
android:id="#+id/qrcodetext"
android:gravity="center"
android:layout_weight="1"
android:layout_gravity="center_horizontal"
android:layout_marginTop="4dp" />
<LinearLayout
android:layout_height="match_parent"

Remove Strange Space between RecyclerView Items

I am newbie to android development and learning it to my own. I have a very strange problem of having strange space that comes in between every item of my recycler view. I have the following:
My recycler view is vertical with grid view layout of 2 spans(columns). What I have been trying is:

Screen Shot
The Black space is showing the extra strange space that I want to remove.

Change:
<LinearLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical">
<LinearLayout
android:layout_width="match_parent"
android:layout_height="0dp"
android:layout_weight="50">
<ImageView
android:id="#+id/album_image"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:background="#color/blackColor"
/>
</LinearLayout>
to
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="vertical">
<LinearLayout
android:layout_width="match_parent"
android:layout_height="0dp"
android:layout_weight="50">
<ImageView
android:id="#+id/album_image"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:background="#color/blackColor"
/>
</LinearLayout>
That is change the height of the second parent linear layout to wrap_content
