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
android:id="#+id/future_weather_fragment"
android:name="com.example.wheatherapp.UI.Weather.FutureWeather.FutureWeatherListFrag.FutureWeatherFragment"

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);

How to create custom Table Layout with headers and grid lines

I spent almost the whole weekend to figure out how to create a table structure with headers for columns and rows and include ImageButtons in the cells of the table. The grid lines should be visible.
I tried lot of different layouts... Grid, Linear, Structured, CoordinatorLayout .... view nested GridViews and so on. But couldn't figure out how to accomplish something like this?
Some kind of nested layout magic?

Create a drawable cell_shape.xml
<?xml version="1.0" encoding="utf-8"?>
<shape
xmlns:android="http://schemas.android.com/apk/res/android"
android:shape= "rectangle" >
<stroke android:width="0.5dp" android:color="#4E4E4E"/>
</shape>
In your styles.xml define your custom cell style
<style name="Cell">
<item name="android:layout_width">0dp</item>
<item name="android:layout_height">match_parent</item>
<item name="android:layout_weight">1</item>
<item name="android:background">#drawable/cell_shape</item>
<item name="android:gravity">center</item>
<item name="android:paddingTop">8dp</item>
<item name="android:paddingBottom">8dp</item>
<item name="android:textSize">12sp</item>
</style>
table_layout.xml
<?xml version="1.0" encoding="utf-8"?>

Textviews at the end of screen in LinearLayout

its a simple linear layout with 1 ImageView and 6 TextViews and a ScrollView but TextViews are appearing at the end of the screen and not below ImageView. I have tried editing my dp values in styles.xml but still not working please have a look!!
I have also tried editing my ImageView tags but still not working and don't know why TextViews are appearing at the end of the screen and if I remove ScrollView the texts are not visible.
Layout code:

You ImageView hight is wrap_content this the reason why your textview are at the bottom of your screen
Try this set static height to your ImageView
<ImageView
android:scaleType="fitStart"
android:adjustViewBounds="true"
android:layout_width="match_parent"
android:layout_height="150dp"
android:contentDescription="#string/photo_description"
android:src="#drawable/photo"
android:id="#+id/image"/>

Try this!
In your <ImageView> scaleType is android:scaleType="fitStart" change it to android:scaleType="fitXY"

Don't use Scrollview as parent view and add android:adjustViewBounds="true" to Imageview for fit.

Android: Changing color of the back button in tool bar

I am trying to make the back button on the toolbar black, but I can't find a way. For some reason I don't have toolBar in my xml file, so there is no way to change the color for me. Please let me know if there is another way.
I have the primaryColor white, but the back button is also white.
<style name="AppTheme" parent="Theme.AppCompat.Light.DarkActionBar">
<!-- Customize your theme here. -->
<item name="colorPrimary">#color/colorPrimary</item>
<item name="colorPrimaryDark">#color/colorPrimaryDark</item>
<item name="colorAccent">#color/colorAccent</item>
<item name="colorControlNormal">#color/colorPrimaryDark</item>
<item name="actionMenuTextColor">#color/colorPrimaryDark</item>

This is my xml file

android:id="#+id/toTimeEditText"

android:hint="toTime"
android:textAlignment="center" />
</LinearLayout>
</LinearLayout>

if you are using toolbar then you can change
toolbar.getNavigationIcon().setColorFilter(getResources().getColor(R.color.blue_gray_15), PorterDuff.Mode.SRC_ATOP);

Shadow effect (elevation) is hiding after app was launched

I have a problem with elevation effect in my app (shadow under TabLayout exactly) that is collapsing after I'm running my App. It's visible in preview mode but not on my device cause it's hiding. This is my code:

I want to achieve simple shadow effectt that is not hiding under tablayout to seperate from the rest of the content. I'm testing it on my phone with android 6.0.1

I've found a solution to my problem. I have created Relative layout with view inside that imitates shadow. Adding this line of code after TabLayout and before end of AppBarLayout solved everything.
<RelativeLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
app:layout_anchor="#id/tabs"
app:layout_anchorGravity="bottom"
android:background="#android:color/white">
<View
android:layout_width="match_parent"
android:layout_height="4dp"
android:layout_alignParentBottom="true"
android:background="#drawable/tablayout_shadow"
/>

Finally after 2 days of brainstorming i solved it:D. I hope this will help someone in future.
