How to make the lower navigation bar show what's the last thing in the activity?

I was trying to make a lower navigation bar and because the views where a lot I needed to use a scroll view but the problem is that the last element in the scroll view doesn't appear because of the navigation bar.
so what can I do to make last element appear??
my xml code is :

so how can I make the last element in the scroll view because the navigaion bar is blocking it (it's in the front of it so the last element doesn't show.
This is an image of it and as you can see the navigation bar is in the front of the last element so it doesn't show because of that

Add id to Bottom navigation bar LinearLayout
Add android:layout_above="#+id/yourbottomlayoutid" , android:layout_height="match_parent" and android:fillViewport="true" to your ScrollView.
For reference check below code:
<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:background="#E6E6E6"
android:layout_height="match_parent"
tools:context=".mainPage">
<ScrollView
android:layout_width="match_parent"
android:layout_height="match_parent"
android:fillViewport="true"
android:layout_above="#+id/llBottomBar">
<!--Your LinearLayout-->
</ScrollView>
<LinearLayout
android:id="#+id/llBottomBar"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_alignParentBottom="true"
android:orientation="horizontal">
<!--Bottom navigation bar buttons-->
</LinearLayout>
</RelativeLayout>

Add android:paddingBottom = "Xdp", where X is something bigger than your bottom bar, to the last LinearLayout.
Example: android:paddingBottom = "30dp"

Try to use framlayout and xml like below
<?xml version="1.0" encoding="utf-8"?>
<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:layout_width="match_parent"
android:layout_height="match_parent" >
<EditText
android:id="#+id/edit_text_message"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_gravity="bottom|center_vertical"
android:layout_marginLeft="12dp"
android:background="#null"
android:layout_alignParentBottom="true"
android:hint="Enter you something"
android:inputType="textCapSentences|textMultiLine"
android:maxLength="2000"
android:maxLines="8" />
</FrameLayout>

If your using relative layout , in the edit text tag add this.
android:layout_alignParentBottom="true"

Duplicate the some part of layout each time the button is clicked in android

Move the linear layout part with id linear_layout_add_more in listview layout. And include this listview in your xml.
On button click increse the listview item size and call notifydatasetchanged on listview adapter

You can create a parent view in your layout
<LinearLayout
android:id="#+id/duplicate_view_container"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="vertical"
> </LinearLayout>
and create a seperate layout which will contains all view you wants to add repetitively for example child_layout.xml. Now on click of button you can inflate child_layout.xml and add it to duplicate_view_container.

ScrollView: Button is not visible completely

I have a Problem with one activity xml in my Android project.
Its a ScrollView and inside i have a LinearLayout. In the LinearLayout i added a Button.
But the button is not completely visible. Only 2px or like that.
<?xml version="1.0" encoding="utf-8"?>
<ScrollView xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent">
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="vertical">
<ImageView
android:layout_width="match_parent"
android:layout_height="match_parent"
android:id="#+id/image_view_one"
android:scaleType="fitCenter"
android:adjustViewBounds="true"
/>
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Titel"
android:textSize="20dp"
android:layout_gravity="center_horizontal"
android:layout_margin="10dp"
android:textColor="#000000"
android:id="#+id/textview_titel"
/>
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Content"
android:textSize="15dp"
android:layout_margin="10dp"
android:textColor="#000000"
android:id="#+id/textview_description"
/>
<android.support.v7.widget.AppCompatButton
android:id="#+id/btn_zum_gewinnspiel"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_marginLeft="10dp"
android:layout_marginRight="10dp"
android:layout_marginTop="10dp"
android:layout_marginBottom="10dp"
android:padding="12dp"
android:text="ZUM GEWINNSPIEL"
android:background="?attr/colorPrimary"
android:textSize="18dp"
/>
</LinearLayout>
</ScrollView>

Give bottomPadding in LinearLayout.

How do I ensure the buttons align horizontally in this Android login dialog?

I'm creating a login dialog on Android where I want two buttons to align horizontally both on the top and bottom edge, irregardless of the screen size. Sometimes "Forgot password" will break over two lines, sometimes not. I do not want to impose a minHeight on the buttons, and would prefer a solution based on XML design only (not code).
Landscape is fine:
Portrait, default implementation leaves the login button shorter than "forgot password"
One solution I tried was setting match_parent for the layout_height param of the first button. Didn't quite work:
XML:
<LinearLayout
android:orientation="horizontal"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_gravity="center_horizontal"
android:id="#+id/terms_layout"
android:layout_marginTop="10dp"
>
<Button
android:layout_width="0dp"
android:layout_height="match_parent"
android:layout_weight="1"
android:text="#string/login"
android:textSize="18sp"
android:id="#+id/dialog_login_button_login"
/>
<Button
android:layout_width="0dp"
android:layout_height="wrap_content"
android:layout_weight="1"
android:text="#string/forgotPassword"
android:textSize="18sp"
android:id="#+id/dialog_login_button_forgot_password"
/>
</LinearLayout>

Use RelativeLayout and make "Login" button to align to the top and bottom of "Forgot Password" Button

As #manjusg answered, make the Login button align the bottom and top to the other button.
Here is how I did it:
<?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">
<EditText
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:hint="Email" />
<EditText
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:hint="Password" />
<RelativeLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_gravity="center_horizontal"
android:id="#+id/terms_layout"
android:layout_marginTop="10dp">
<View
android:id="#+id/center_strut"
android:layout_height="0dp"
android:layout_width="0dp"
android:layout_centerInParent="true" />
<Button
android:layout_width="0dp"
android:layout_height="0dp"
android:text="Login"
android:textSize="18sp"
android:layout_alignParentLeft="true"
android:layout_alignRight="#+id/center_strut"
android:layout_alignBottom="#+id/dialog_login_button_forgot_password"
android:layout_alignTop="#+id/dialog_login_button_forgot_password"
android:id="#+id/dialog_login_button_login" />
<Button
android:layout_width="0dp"
android:layout_height="wrap_content"
android:layout_alignParentRight="true"
android:layout_alignLeft="#+id/center_strut"
android:text="Forgot Password"
android:textSize="18sp"
android:id="#+id/dialog_login_button_forgot_password" />
</RelativeLayout>
</LinearLayout>

replace your xml with this xml
<LinearLayout
android:orientation="horizontal"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_gravity="center_horizontal"
android:id="#+id/terms_layout"

android:weightSum="2"
>
<RelativeLayout
android:layout_width="0dp"
android:layout_height="match_parent"
android:layout_weight="1"
>
<Button
android:layout_width="match_parent"
android:layout_height="match_parent"
android:text="#string/login"
android:textSize="18sp"
android:id="#+id/dialog_login_button_login"
android:layout_alignParentTop="true"
android:layout_alignParentBottom="true"
/>
</RelativeLayout>
<RelativeLayout
android:layout_width="0dp"
android:layout_height="match_parent"
android:layout_weight="1"

<Button

android:layout_weight="1"
android:text="#string/forgotPassword"
