How to make Android xml Linerlayout at the bottom of the activity in Android Studio?

How do I make LinearLayout in Android Studio at the bottom of the page. The result from the code below
I want the highlighted darken layout to be at the bottom of the page.
<?xml version="1.0" encoding="utf-8"?>
<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"
tools:context=".MainPage"
android:orientation="vertical"
android:background="#ffffff">
<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"/>
<!--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: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>
In the above code I tried the below and did not worked.
android:layout_alignParentBottom="true"
android:layout_gravity="bottom"
android:gravity="bottom"

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.

Android XML: Vertical Seekbar in Android with match parent layout isn't working properly

I have seen a different post related to this topic already before posting this question so I can definitely say that this question is not a duplicate. I have a different problem which I couldn't fix or find a solution to it.
Problem: I have created a Vertical Seekbar using new <SeekBar> </SeekBar> view. It does look fine when I see the preview in Android Studio but on the device, the SeekBar doesn't fill the height of the screen. I have rotated the SeekBar view with 90deg and try to set the height:match_parent and width:wrap_content but it isn't working at all as I expected. So I set the height to some hard-coded value and it looked fine. The only problem is, I will have to check the height of the view in which it is getting populated and set the height of the SeekBar problematically, which I want to avoid.
slider.xml
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/slider"

android:layout_gravity="center"

android:paddingBottom="16dp"/>
<FrameLayout

android:layout_height="match_parent">

android:layout_height="match_parent"

You are setting weight inside the Framelayout when the orientation is vertical and at the same time the height of FrameLayout is set to match_parent. If you are setting like this there will be no effect of the weight. Try setting the height to 0dp it will work for sure.
<FrameLayout
android:layout_weight="1"
android:background="#fff"
android:layout_width="match_parent"
android:layout_height="0dp">
<SeekBar
android:id="#+id/seeker"
android:layout_width="wrap_content" // set this to 400dp and it looks fine
android:layout_height="match_parent"
android:rotation="270"
android:layout_gravity="center"/>
</FrameLayout>
This is my result

You need to get rid of your FrameLayout which is limiting the width of the SeekBar. I tried to implement the layout like the following and I think it should fit in your case as well.
Another important thing you should notice that, because of your rotation, the width and height are interchanged in the view for your SeekBar. Hence I made the layout_width="match_parent". Hope that helps!
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/slider"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_gravity="center"
android:elevation="5dp">
<TextView
android:id="#+id/text"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_centerHorizontal="true"
android:layout_marginTop="30dp"
android:padding="16dp"
android:text="100"
android:textAlignment="center" />
<SeekBar
android:id="#+id/seeker"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_centerInParent="true"
android:layout_gravity="center"
android:rotation="270" />
<ImageView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentBottom="true"
android:layout_centerHorizontal="true"
android:layout_marginBottom="20dp"
android:padding="16dp"
android:src="#android:drawable/star_on" />
</RelativeLayout>
Here is the result that I have got.

<RelativeLayout
android:layout_width="400dp"
android:layout_height="200dp"
android:layout_gravity="center">
<SeekBar
android:layout_width="400dp"
android:layout_height="match_parent"
android:layout_gravity="center"
android:maxHeight="4dp"
android:minHeight="4dp"
android:progress="50"
android:progressDrawable="#drawable/custom_seek_bar"
android:rotation="270"
android:thumb="#drawable/seekbar_thumb" />
</RelativeLayout>
Use this code, you will get desired result

Top ActionBar covers pages content

I'm creating an android app and I've just added a Navigation drawer into one of my activities. I've successfully added it in, however, it now overlaps the content of the page. The jobs text and the rest should be below the ActionBar.
I've tried adding a margin to the top of the jobs text which does push it down as I wish. Is there a better way to move it down?

Becoz you assign the gravity="top" in Linearlayout so its happens
so u remove this gravity see my below code:
<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:id="#+id/jobListPage"
android:layout_width="match_parent"
android:layout_height="match_parent"
//remove gravity="top" from hear
tools:context="com.kitkat.crossroads.Jobs.JobsActivity">
if your problem not solve then u can take android:layout_marginTop="20dp" in inner Linearlayout
see below code
<LinearLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_marginTop="20dp"
android:orientation="vertical">
Don't take a include in LinearLayout. Becoz its change your actionbar so u can only remove gravity and assign margin top

I believe you should put
<include
layout="#layout/app_bar_main"
android:layout_width="match_parent"
android:layout_height="match_parent" />
inside
<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:id="#+id/jobListPage"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:gravity="top"
tools:context="com.kitkat.crossroads.Jobs.JobsActivity">

The reason why I was having the overlap was because I put the page content in the activity_main.xml layout and not the content_main.xml. Putting the content in that layout sorted the issue out and put the content below the action bar.

Header image can't fit correctly (DrawerLayout)

I need help. I've been trying to manipulate this but seems like I can't get this done. I'm trying to fit the image on drawer layout.
I'm invoking the header image layout (header.xml) as :
<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/drawerLayout"
android:layout_width="match_parent"
android:layout_height="match_parent">
<FrameLayout
android:id="#+id/containerView"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical"/>
<android.support.design.widget.NavigationView xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
....
app:headerLayout="#layout/header" <!--THIS IS THE HEADER-->
...
</android.support.v4.widget.DrawerLayout>
For this (header.xml) configuration :
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical" android:layout_width="match_parent"
android:layout_height="match_parent">
<ImageView
android:layout_width="match_parent"
android:layout_height="match_parent"
android:src="#drawable/background"
android:layout_marginBottom="0dp"/>
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text=" Twitter : #Someone important"
android:drawableLeft="#drawable/twitter"
android:layout_marginBottom="0dp"
/>
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text=" e-mail : someoneimportant#earth"
android:drawableLeft="#drawable/email"
/>
</LinearLayout>
I got
and tried to reduce the image layout height :
<?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="match_parent">
<ImageView
android:layout_width="match_parent"
android:layout_height="140dp"
android:src="#drawable/background"
android:layout_marginBottom="0dp"/>
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text=" Twitter : #Someone important"
android:drawableLeft="#drawable/twitter"
android:layout_marginBottom="0dp"
/>
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text=" e-mail : someoneimportant#earth"
android:drawableLeft="#drawable/email"
/>
</LinearLayout>
I got the image cut off.

your image is not able to fit the screen because of the image size so you can set the scale type as fitxy in this way it will fill the left space and strech the image
<ImageView
android:layout_width="match_parent"
android:layout_height="140dp"
android:src="#drawable/background"
android:scaleType="fitXY"
android:layout_marginBottom="0dp"/>

Overlap Layout with ImageView

Im trying to create the following Layout:
The border of the RelativeLayout is realized with a rectangle shape as background, but I cannot get the ImageView overlap the RelativeLayout with half of it in and half of it out of the border. Is this even possible with RelativeLayout (And if not: What alternative do I have)?
layout.xml
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent">
<ImageView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:id="#+id/imageView"
android:src="#drawable/imageresource"
android:layout_alignParentTop="true"
android:layout_centerHorizontal="true"/>
<RelativeLayout
android:padding="#dimen/item_inner_margin"
android:background="#drawable/item_border"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:id="#+id/relativeLayout"
android:layout_below="#+id/imageView">
<!-- Stuff in the layout -->
</RelativeLayout>
</RelativeLayout>
