In the above code I tried the below and did not worked.
android:layout_alignParentBottom="true"

You can use RelativeLayout at the outside. Something like this, and then ADD new one LinearLayout after that.
<?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:background="#ffffff"
android:orientation="vertical"
tools:context=".MainPage">
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="vertical">
<Button
android:id="#+id/taptoscan"
android:layout_width="120dp"
android:layout_height="120dp"
android:layout_gravity="center"
android:layout_marginTop="40dp"
android:layout_marginBottom="10dp"
android:background="#drawable/barcode" />
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="center"
android:fontFamily="#font/antic"
android:text="Tap to Scan"
android:textSize="18sp" />
</LinearLayout>
<!--here is the layout i want to put at the bottom of the page-->
<LinearLayout
android:layout_width="match_parent"
android:layout_height="40dp"
android:layout_alignParentBottom="true"
android:layout_gravity="bottom"
android:background="#color/colorPrimaryDark"
android:gravity="bottom"
android:orientation="horizontal">
<RelativeLayout
android:layout_width="wrap_content"
android:layout_height="wrap_content" />
</LinearLayout>
</RelativeLayout>


Use Frame Layout as base layout to do it in the best way, it's gonna work definitely
Just use layout_gravity="bottom" in the LinearLayout which you want at bottom and
Just like this :
<?xml version="1.0" encoding="utf-8"?>
<FrameLayout 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:background="#ffffff"
android:orientation="vertical"
tools:context=".MainPage">
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="vertical">
<Button
android:id="#+id/taptoscan"
android:layout_width="120dp"
android:layout_height="120dp"
android:layout_gravity="center"
android:layout_marginTop="40dp"
android:layout_marginBottom="10dp"
android:background="#drawable/barcode" />
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="center"
android:fontFamily="#font/antic"
android:text="Tap to Scan"
android:textSize="18sp" />
</LinearLayout>
<LinearLayout
android:layout_width="match_parent"
android:layout_height="40dp"
android:layout_gravity="bottom"
android:background="#color/colorPrimaryDark"
android:orientation="horizontal">
<RelativeLayout
android:layout_width="wrap_content"
android:layout_height="wrap_content" />
</LinearLayout>
</FrameLayout>


The approach below would help you achieve your design specifications with zero overlappings. Basically, there are four key steps:
Change your root layout to a RelativeLayout.
Inside the RelativeLayout, add a LinearLayout that would contain your Button and your TextView.
Inside the same RelativeLayout, add the LinearLayout that you intend to pin to the bottom of the screen.
Make sure yoU set the first LinearLayout on top of the second by using the android:layout_above="" attribute.
Now, here's the code:
<?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="match_parent"
tools:context=".MainPage">
<LinearLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical"
android:background="#ffffff"
android:layout_above="#+id/bottomView">
<Button
android:id="#+id/taptoscan"
android:layout_marginTop="40dp"
android:layout_marginBottom="10dp"
android:layout_width="120dp"
android:layout_height="120dp"
android:background="#drawable/barcode"
android:layout_gravity="center"/>
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Tap to Scan"
android:fontFamily="#font/antic"
android:layout_gravity="center"
android:textSize="18sp"/>
</LinearLayout>
<!--here is the layout i want to put at the bottom of the page-->
<LinearLayout
android:layout_width="match_parent"
android:layout_height="40dp"
android:id="#+id/bottomView"
android:background="#color/colorPrimaryDark"
android:orientation="horizontal"
android:layout_alignParentBottom="true"
android:layout_gravity="bottom"
android:gravity="bottom">
<RelativeLayout
android:layout_width="wrap_content"
android:layout_height="wrap_content">
</RelativeLayout>
</LinearLayout>
</RelativeLayout>
I hope this helps.

I want to put button like above picture. But I have below image. I can't success this. Search a lot of but can't find it.
LinearLayout in LinearLayout has transparent background and there is button left of this.
Activity.xml :
<?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="match_parent"

</LinearLayout>
</LinearLayout>

remove android:paddingLeft="40dp from LinearLayout Tag

Just remove below code from your "LinearLayout"
android:paddingLeft="40dp"
This is adding extra padding to your parent layout.
Below will be your final code.
<?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="match_parent"

android:orientation="vertical" >
<LinearLayout
android:orientation="vertical"
android:layout_width="750dp"
android:layout_height="wrap_content"
android:layout_gravity="center_vertical|center_horizontal"
android:background="#drawable/lay_transparan_aramasecenek"
android:layout_marginTop="100dp">
<LinearLayout
android:orientation="vertical"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:background="#drawable/lay_transparan_aramasecenek_beyaz">

android:layout_height="wrap_content"
android:scaleType="fitCenter"
android:background="#drawable/kod_ile_arama"

Try this code for batter result for your Button Icon. I Hope it is helpful for You.

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" />

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>

android layout image at left and two text block at right

I want a layout like this
Layout where an image at the bottom and two text block at right
It's a very simple layout with an image at left and two text blocks at right. I know how to do this in html and CSS but no idea how to do this in XML. What are the properties to float elements left or right? Right now if I add an image and two text blocks, the second text block is not shown.

Try this code, I've tested it:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="horizontal" android:layout_width="match_parent"
android:layout_height="match_parent">
<ImageView
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_gravity="center"
android:layout_weight="1"/>
<LinearLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_weight="1"
android:orientation="vertical">
<TextView
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_weight="1"
android:gravity="center"/>
<TextView
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_weight="1"
android:gravity="center"/>
</LinearLayout>

<?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="match_parent"
android:orientation="horizontal">
<LinearLayout
android:layout_width="0dp"
android:layout_height="match_parent"
android:layout_weight="1"
android:orientation="vertical">
<TextView
android:layout_width="match_parent"
android:layout_height="0dp"
android:layout_weight="1"/>
<TextView
android:layout_width="match_parent"
android:layout_height="0dp"
android:layout_weight="1"/>
</LinearLayout>
<ImageView
android:layout_width="0dp"
android:layout_weight="1"
android:layout_height="match_parent" />
</LinearLayout>
Edit it on your own :)

You can use a relative layout for this:
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_height="wrap_content"
android:layout_width="match_parent">
<ImageView android:id="#+id/img"
android:layout_height="wrap_content"
android:layout_width="wrap_content"
android:src="#drawable/ic_clear"/>
<TextView android:id="#+id/text1"
android:layout_height="wrap_content"
android:layout_toEndOf="#+id/img"
android:layout_toRightOf="#+id/img"
android:layout_width="match_parent"
android:text="text 1"/>
<TextView android:layout_below="#+id/text1"
android:layout_height="wrap_content"
android:layout_toEndOf="#+id/img"
android:layout_toRightOf="#+id/img"
android:layout_width="match_parent"
android:text="text 2"/>
</RelativeLayout>

The problem is if I run this on my phone, the shadow doesn't appear but in Preview mode in Android Studio the shadow shows correctly. How to fix it ?

In the relative layout which is a parent for linear layout that you want elevation set these two attributes: android:clipToPadding="false" and android:paddingbottom="5dp". Do not make any changes in linear layout.

Dynamically adjust position of Button in Android Studio

I have a Button in Linear Layout when I see in the Design view of Activity xml ,it looks like it is perfectly positioned but when I see in GenyMotoin avd it is farly placed from what I expected.
How to dynamically adjust the position of button on different screen sizes?
My xml file:
<?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:paddingBottom="#dimen/activity_vertical_margin"
android:paddingLeft="#dimen/activity_horizontal_margin"
android:paddingRight="#dimen/activity_horizontal_margin"
android:paddingTop="#dimen/activity_vertical_margin"
tools:context="com.xxx.MainScreen"
android:background="#b6b6b6">
<LinearLayout
android:orientation="horizontal"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_alignParentTop="true"
android:layout_alignParentLeft="true"
android:layout_alignParentStart="true">
<TextView
android:layout_width="match_parent"
android:layout_height="263dp"
android:id="#+id/textView"
android:textSize="50dp" />
</LinearLayout>
<LinearLayout
android:orientation="horizontal"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_marginTop="264dp">
<Button
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Next Act"
android:id="#+id/button"
android:layout_marginTop="100dp"
android:layout_marginLeft="20dp" />
</LinearLayout>
</RelativeLayout>

Use Linear Layout for the outermost layout.

It's not clear what your trying to achieve but If you want to position your views at the center on all devices. Try to use RelativeLayout instead of LinearLayout:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout 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:background="#b6b6b6"
android:padding="#dimen/activity_vertical_margin"
android:weightSum="2"
android:orientation="vertical"
tools:context="com.offtogeek.motivatemyself.MainScreen">
<RelativeLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_weight="1"
android:orientation="horizontal">
<TextView
android:id="#+id/textView"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_centerInParent="true"
android:gravity="left"
android:textSize="50dp" />
</RelativeLayout>
<RelativeLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_weight="1"
android:orientation="horizontal">
<Button
android:id="#+id/button"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_centerInParent="true"
android:layout_weight="1"
android:text="Next Quote" />
</RelativeLayout>
</LinearLayout>
