set Label Alignment in navigation Fragments

I want the label(toolbar title) to be aligned centered.What should I do? I have reffered to some logics and didn't find them effective and they also didn't work. So kindly guide me through it.
This is the Navigation File:
<?xml version="1.0" encoding="utf-8"?>
<navigation 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/mobile_navigation"
app:startDestination="#id/current_weather_fragment">
<fragment
android:id="#+id/current_weather_fragment"
android:name="com.example.wheatherapp.UI.Weather.CurrentWeather.CurrentWeatherFragment"
android:label="current_weather_fragment"
tools:layout="#layout/current_weather_fragment" />
<fragment

1) Add Textview for your toolbar title into your tag which is located in MainActivity.xml in your case.
<com.google.android.material.appbar.AppBarLayout
android:id="#+id/appbar_layout"
android:layout_width="match_parent"
android:layout_height="wrap_content"
app:layout_constraintTop_toTopOf="parent"
app:layout_constraintStart_toStartOf="parent"
app:layout_constraintEnd_toEndOf="parent"
android:theme="#style/ToolbarTheme">
<androidx.appcompat.widget.Toolbar
android:id="#+id/toolbar"
android:layout_width="match_parent"
android:layout_height="?actionBarSize"
android:background="?colorPrimary">
<TextView
android:id="#+id/title"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="center"
android:text="Borrowers"
android:textColor="#color/white"
android:textSize="18dp" />
</androidx.appcompat.widget.Toolbar>
</com.google.android.material.appbar.AppBarLayout>
2) Add toolbar to your MainActivity.java in onCreate() method.
//set toolbar
Toolbar toolbar = findViewById(R.id.borrowerstoolbar_main);
setSupportActionBar(toolbar);
getSupportActionBar().setTitle(null);

Status bar overlapping with activity

Problem
Status bar overlapping with Toolbar. I have tried to setting various attributes but it isn't working out. So now suggest me what to do with this issue and what is causing this issue.
One more thing to note is that I've used transparent status bar attribute in one other activity.

Scroll to EditText in NestedScrollView is not working

I have long scroll form, and I need to scroll to its position on form is not valid input (for example, scroll to email edit text when it's not valid email or empty field)
I am facing 2 issues with scroll to EditText inside NestedScrollView
When one edit text is focused, all times scroll to take me directly to the focused scroll view, not to provided view coordinate
When there is no focused item, it's scrolling in a bad way, the wanted Edittext showing trimmed from the button
Note: I am using NestedScrollView with CoordinateLayout

You must add this attribute android:fitsSystemWindows="true" in parent (DrawerLayout). To fix the white status bar while using it.
To know more about it refer this link Why would I want to fitsSystemWindows?
