How to hide or keep bottom navigation down when keyboard appears while letting texteditor toolbar to move up and down?

I have a bottom navigation view and a texteditor toolbar which appears on top of bottom navigation.I want that when an edittext is clicked and keyboard pops up, bottom navigation hide and only toolbar moves with the keyboard.
I have tried android:windowSoftInputMode="adjustResize" but it allow both bottomnavigation and toolbar to move. I've also tried using android:windowSoftInputMode="adjustPan",however, both toolbar and navigation stop appearin on top of keyboard.
Here is my activity layout file:
<RelativeLayout
android:layout_width="match_parent"
android:fitsSystemWindows="true"
android:layout_height="match_parent">
<!-- top toolbar -->
<RelativeLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:id="#+id/rellayout1">
<include layout="#layout/layout_top_tabs"/>
</RelativeLayout>
<!--middle section body -->
<RelativeLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:id="#+id/rellayout2"
android:layout_marginBottom="50dp"
android:layout_below="#+id/rellayout1">
<include layout="#layout/layout_centre_viewpager"/>
<fragment
android:id="#+id/fragment"
android:name="com.Write.TitleFrag"
android:layout_marginTop="5dp"
android:layout_width="match_parent"
android:layout_height="wrap_content"
tools:layout="#layout/fragment_title" />
<fragment
android:id="#+id/fragment2"
android:name="com.Write.BodyFrag"
android:layout_width="match_parent"
android:layout_marginTop="5dp"
android:layout_height="wrap_content"
android:layout_below="#+id/fragment"
tools:layout="#layout/fragment_body" />
</RelativeLayout>
<!-- bottom navigation -->
<RelativeLayout
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:id="#+id/WriteBottomNav">
<include layout="#layout/layout_bottom_navigation_view"/>
</RelativeLayout>
</RelativeLayout>
fragment2 contains editor and toolbar.
Here is fragment2 layout file:
<RelativeLayout
android:layout_width="match_parent"
android:layout_height="match_parent">
<ScrollView
android:id="#+id/scrollView"
android:layout_width="match_parent"

android:paddingTop="10dp"
android:paddingRight="20dp"
android:focusedByDefault="true"
android:paddingBottom="100dp"

Since there is no reliable way to tell when a keyboard is showing/shown, there's no reliable way to do this. Neither input mode options know anything about navigation, there's no built in way to do this. And there's no way to get notified when a soft keyboard appears. Your best option is to not need this functionality.

Is there a way to check overview button?

I am developing an app where there is a left Drawer on the Home screen. The drawer fits perfectly on most devices, but on some devices, the drawer is covered whether the screen has overview button(phone without physical button, using on screen button) or its swallowed under the bottom of the screen(mostly happen on Xiaomi, and yes, i've tried on 5 xiaomi phones).This also happening on the emulator from android studio. The Question is, can the app knows if there a overview button on the phone , so the app can be developed to put the layout on top(not covering) of it. Or is there another way, more simple and efficient?

On the picture i scrolled down until cant be scrolled anymore

Sorry, if I dont understand your question.
I dont see in your xml android.support.design.widget.NavigationView - its container for drawer content. You need to add implementation 'com.android.support:design:27.1.1' to your app dependencies to use NavigationView.
And if you want to do static header for your drawer, there is app:headerLayout="#layout/nav_header" property, where nav_header is your header layout.
For other items there are app:menu="#menu/drawer_view property, where drawer_view is your drawers menu. In this menu you can put as many items as you wish and they will be scrollable if needed. Also you can design it as you want and they are easy for handling in NavigationView.OnNavigationItemSelectedListener
See this Googles guide for more details. Hope it will help you.

This is a common problem. Place a listview (or more) inside a scrollview is not good. If you have a finite number of elements I suggest you to build your view programmatically (use addView).
However if you don't want to change your code read that: list view inside scrollview.
Basically you need to calculate the real height of the listview for every item (getMeasuredHeight) after notifyDataSetChanged. This should fix your problem.

To prevent overlapping by Bottom Soft NavigationBar add this to your styles.xml in a values-v21 dir (if dir not exist, create one and copy same styles.xml file from value):
<item name="android:windowDrawsSystemBarBackgrounds">false</item>
Like this eg -
<style name="Theme" parent="Theme.AppCompat.Light.DarkActionBar">
<item name="android:windowDrawsSystemBarBackgrounds">false</item>
.....
.....
</style>

RecyclerView Becomes Focused when DrawerLayout is Closed

This is sort of a strange bug I discovered.
But if I have a RecyclerView in a fragment and I open then close my DrawerLayout, my RecyclerView comes in focus. That means closing my DrawerLayout will cause the ScrollView to jump to my RecyclerView. Obviously, I would like the ScrollView's position to not move when the DrawerLayout is closed, and definitely not settle on my RecyclerView.
CODE
Throughout my application, I have RecyclerViews contained within ScrollViews, similar to this setup:
<ScrollView xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent">
<LinearLayout
android:orientation="vertical"
android:layout_width="match_parent"
android:layout_height="wrap_content">
<RelativeLayout
android:layout_alignParentTop="true"
android:layout_width="match_parent"
android:layout_height="180dp">
<android.support.v7.widget.AppCompatImageView
android:id="#+id/header_photo"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:adjustViewBounds="true"
android:tint="#80000000"
android:scaleType="centerCrop"/>
<LinearLayout
android:orientation="vertical"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_centerVertical="true"
android:layout_centerHorizontal="true">
<TextView android:id="#+id/header_text"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="center"
android:gravity="center"
android:paddingTop="2dp"
android:paddingBottom="2dp"
android:textColor="#color/text_SecondaryColor"
android:textSize="#dimen/header_xxlarge"/>
<View android:id="#+id/divider"
android:layout_width="0dp"
android:layout_height="#dimen/hr_thick"
android:background="#color/accent_PrimaryColor"/>
</LinearLayout>
</RelativeLayout>
<LinearLayout
android:orientation="vertical"
android:layout_margin="20dp"
android:layout_width="match_parent"
android:layout_height="wrap_content">
<android.support.v7.widget.RecyclerView
android:id="#+id/recyclerview"
android:layout_width="match_parent"
android:layout_height="wrap_content"/>
<Button android:id="#+id/button_more"
android:layout_marginTop="6dp"
android:layout_marginBottom="6dp"
android:layout_width="400px"
android:layout_height="100px"
android:layout_gravity="center"
android:gravity="center"
android:background="#drawable/button_dark"
android:textColor="#drawable/button_dark_textcolor"/>
</LinearLayout>
</LinearLayout>
</ScrollView>
And my DrawerLayout's XML design is arranged like this:
<LinearLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical">
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="vertical">
<include
android:layout_height="wrap_content"
android:layout_width="match_parent"
layout="#layout/toolbar" />
</LinearLayout>
<FrameLayout
android:id="#+id/contentframe"
android:layout_width="match_parent"
android:layout_height="match_parent" />
</LinearLayout>
<RelativeLayout
android:layout_width="300dp"
android:layout_height="match_parent"
android:layout_gravity="start"
android:background="#color/background_Secondary">
<!-- Relative Layout : Back Button -->
<RelativeLayout
android:id="#+id/menu_backcontainer"
android:layout_width="match_parent"
android:layout_height="?attr/actionBarSize">
<ImageView
android:id="#+id/menu_back"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginRight="20dp"
android:src="#drawable/angle"
android:layout_centerVertical="true"
android:layout_alignParentEnd="true" />
</RelativeLayout>
<!-- List View : Menu Drawer Content -->
<ListView
android:id="#+id/menu"
android:layout_below="#id/menu_backcontainer"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:choiceMode="singleChoice"
android:background="#color/background_PrimaryDarkColor">
</ListView>
</RelativeLayout>
</android.support.v4.widget.DrawerLayout>
I am not sure what other Java Code I need to include here but this is how I instantiate my RecyclerView:
recyclerView = (RecyclerView)view.findViewById(R.id.recyclerview);
LinearLayoutManager layoutManager = new LinearLayoutManager(getContext().getApplicationContext());
recyclerView.setLayoutManager(layoutManager);
recyclerView.setNestedScrollingEnabled(false);
And For My DrawerLayout:
drawerlayout = (DrawerLayout)findViewById(R.id.drawer);
menu = (ListView)findViewById(R.id.menu);
MenuAdapter adapter = new MenuAdapter(
this,
R.layout.listview_menuitem,
menuItemArray);
menu.setAdapter(adapter);
menu.setOnItemClickListener(new menuItemClickListener());
menuToggle = new ActionBarDrawerToggle(
this,
drawerlayout,
toolbar,
R.string.app_name,
R.string.app_name);
drawerlayout.setDrawerListener(menuToggle);
menuToggle.syncState();

Gee, it is amazing what a moment away from the computer and a cup of coffee will do.
I simply set the focusableInTouchMode attribute of my FrameLayout to true.
I guess this nullifies the RecyclerViews desire to be the focused element in the ScrollView when I touch anywhere on the screen after the DrawerLayout is opened. Perhaps there is a better, more thorough explanation. But I hope this helps anyone else who may experience this problem.

Swiperefresh also working on left swipe

i have a listview in a fragment(Total 3 tabs in viewpager) and using this below code to get swipe down to refresh functionality but on swiping left to another fragment swipe refresh function is called how to restrict this(happens only if listview is empty).
<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.support.v4.widget.SwipeRefreshLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/fragmenttab1_swipe_refresh_layout"
android:layout_width="match_parent"
android:layout_height="wrap_content" >
<ListView
android:layout_width="match_parent"
android:layout_height="match_parent"
android:id="#+id/fragmenttab1_list_item"
android:dividerHeight="1dp"
android:focusable="false"
android:focusableInTouchMode="false"
android:longClickable="true">
</ListView>
</android.support.v4.widget.SwipeRefreshLayout>
<TextView android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:id="#+id/fragmenttab1_emptyElement"
android:text="No Posts"
android:textStyle="bold"
android:textSize="15sp"
android:visibility="gone"
android:layout_centerInParent="true"
android:textColor="#android:color/darker_gray"/>
</RelativeLayout>
Java code
listView.setAdapter(adapter);
listView.setEmptyView(getView().findViewById(R.id.fragmenttab1_emptyElement));

Image/ViewPager will not correctly use android:layout_gravity="bottom" and android:layout_alignParentBottom="true"

For some reason android:layout_gravity="bottom" and android:layout_alignParentBottom="true" on my ViewPager (the classical button) do not seem to place the image at the bottom of the screen and I'm unsure why.
Any suggestions are much appreciated.

The Navigation Drawer documentation states (emphasis mine):
To add a navigation drawer, declare your user interface with a DrawerLayout object as the root view of your layout. Inside the DrawerLayout, add one view that contains the main content for the screen (your primary layout when the drawer is hidden) and another view that contains the contents of the navigation drawer.
You cannot have multiple views in your DrawerLayout xml (other than your drawer and content). I would recommend putting your content in a fragment, and then inflating it in code similar to the way the examples do.
