How to set navigationIcon color white in toolbar?

I use toolbar in my application, when I inflate menu in toolbar, navigationIcon color is too dark. I want to set navigationIcon color = white, but I don't know how to do it. Please tell me what can I do?
xml:
<androidx.appcompat.widget.Toolbar
android:id="#+id/toolbar"
android:layout_width="match_parent"
android:layout_height="?attr/actionBarSize"
android:minHeight="?attr/actionBarSize"
android:background="#color/dark"
android:elevation="0dp">
<ImageButton
android:id="#+id/imgbtn_back"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:background="#drawable/ic_back_dark"/>
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="開單作業"
android:textSize="22sp"
android:textColor="#color/white"
android:layout_gravity="left"
android:layout_marginLeft="40dp"/>
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="地"
android:textSize="22sp"
android:textColor="#color/white"
android:layout_gravity="right"
android:layout_marginRight="40dp"/>
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="回"
android:textSize="22sp"
android:textColor="#color/white"
android:layout_gravity="right"
android:layout_marginRight="20dp"/>
</androidx.appcompat.widget.Toolbar>
java:
Toolbar toolbar = findViewById(R.id.toolbar);
toolbar.inflateMenu(R.menu.menu_main);
menu_main:
<menu xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto">
<group>
<item
android:id="#+id/action_about"
android:title="補印"
app:showAsAction="never"/>
<item
android:id="#+id/action_exit"
android:title="補拍"
app:showAsAction="never"/>
</group>

To change the Overflow Menu Icon color via xml define a custom style in styles.xml file and change the android:tint property like below:
<style name="MyToolBarTheme" parent="ThemeOverlay.AppCompat.ActionBar">
<item name="android:tint">#color/white</item>
</style>
and you can use this style in Toolbar using the android:theme attribute like below:
<androidx.appcompat.widget.Toolbar
android:theme="#style/MyToolBarTheme"
android:layout_width="match_parent"
android:layout_height="?attr/actionBarSize">
or in case you want to change it programmatically you can do it like below:
if(toolbar.getOverflowIcon()!=null)
toolbar.getOverflowIcon().setTint(Color.WHITE);

A way to achieve this could be adding a custom style in your styles.xml with the desidered color
<style name="ToolbarColoredIcons" parent="">
<item name="android:textColorSecondary">#color/your_color</item>
</style>
And then apply this style to your toolbar
<androidx.appcompat.widget.Toolbar
android:id="#+id/toolbar"
android:layout_width="match_parent"
android:layout_height="?attr/actionBarSize"
android:minHeight="?attr/actionBarSize"
android:background="#color/dark"
android:elevation="0dp"
android:theme="#style/ToolbarColoredIcons">

Toolbar Background Image Size

I am working in android application. Actually there I have to set an image in place of toolbar. But I don't know what the exact sizes of that image.
I am not asking about actionbar size. I googled it a lot but unable to find the solution.
here is my requirement

You can create a custom toolbar and add it to your activity
<android.support.design.widget.AppBarLayout
android:layout_height="wrap_content"
android:layout_width="match_parent"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:theme="#style/AppTheme.AppBarOverlay"
xmlns:android="http://schemas.android.com/apk/res/android">
<android.support.v7.widget.Toolbar
android:id="#+id/toolbar"
android:layout_width="match_parent"
android:layout_height="?attr/actionBarSize"
android:background="?attr/colorPrimary"
app:popupTheme="#style/AppTheme.PopupOverlay" >
<RelativeLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="horizontal"
>
<ImageView
android:id="#+id/ivUser"
android:layout_width="20dp"
android:layout_height="20dp"
android:background="#drawable/ic_profile"
android:layout_centerVertical="true"
/>
<ImageView
android:id="#+id/tvTitle"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:src="#drawable/ic_logo_light"
android:layout_centerInParent="true"
android:padding="15dp"
/>
<ImageView
android:id="#+id/ivLogout"
android:layout_width="20dp"
android:layout_height="20dp"
android:background="#drawable/ic_logout"
android:layout_centerVertical="true"
android:layout_alignParentRight="true"
android:layout_margin="10dp"
android:visibility="gone"
/>
</RelativeLayout>
</android.support.v7.widget.Toolbar>
You can add this toolbar xml to your activity
<include
layout="#layout/toolbar.xml">
Use this toolbar in activity using below code in your activity
Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
setSupportActionBar(toolbar);
TextView tvTitle = (TextView) toolbar.findViewById(R.id.tvTitle);
ImageView ivUser = (ImageView) toolbar.findViewById(R.id.ivUser);
ImageView ivLogout = (ImageView) toolbar.findViewById(R.id.ivLogout);
getSupportActionBar().setDisplayShowTitleEnabled(false);
Note: Use NoActionBar theme for the activity. To disable the default toolbar
<style name="AppTheme" parent="Theme.AppCompat.Light.NoActionBar">
<!-- Customize your theme here. -->
<item name="colorPrimary">#color/colorPrimary</item>
<item name="colorPrimaryDark">#color/colorPrimaryDark</item>
<item name="colorAccent">#color/colorAccent</item>
<item name="android:windowActionBar">false</item>
<item name="android:windowNoTitle">true</item>
</style>

please try this code in your xml file;
<android.support.constraint.ConstraintLayout 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="com.example.kolektif_merta.testapp.MainActivity">
<android.support.design.widget.AppBarLayout
android:id="#+id/layout_home_appBarLayout_appbar"
android:layout_width="match_parent"
android:layout_height="wrap_content"
app:elevation="0dp"
app:layout_constraintEnd_toEndOf="parent"
app:layout_constraintStart_toStartOf="parent"
app:layout_constraintTop_toTopOf="parent">
<RelativeLayout
android:id="#+id/relativeLayout"
android:layout_width="match_parent"
android:layout_height="56dp">
<android.support.v7.widget.Toolbar
android:id="#+id/toolbar"
android:layout_width="match_parent"
android:layout_height="?actionBarSize">
</android.support.v7.widget.Toolbar>
</RelativeLayout>
</android.support.design.widget.AppBarLayout>
<Button
android:id="#+id/button"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginBottom="8dp"
android:layout_marginEnd="8dp"
android:layout_marginStart="8dp"
android:text="Button"
app:layout_constraintBottom_toBottomOf="parent"
app:layout_constraintEnd_toEndOf="parent"
app:layout_constraintStart_toStartOf="parent" />
</android.support.constraint.ConstraintLayout>
And in your java class inside onCreate method(assuming you are in activity);
toolbar = findViewById(R.id.toolbar);
toolbar.setBackground(ContextCompat.getDrawable(this,R.drawable.test));
Here is the test drawable is 1200x640 as you asked.
Also don't forget the update styles.xml file with:
<style name="AppTheme" parent="Theme.AppCompat.NoActionBar">
Here is the result :
custom toolbar background witm image

No ripple on menu item if actionBar/Toolbar is white

I have white toolbar with menu item showed as action that is a black vector asset from material icons. There is no ripple effect on menu item click because ripple effect is also white. If toolbar background is changed to other color e.g blue, ripple appears. How to change menu item ripple color so it will be visible on white background? I was trying to change colorControlHighlight in AppTheme but it hasn't changed menu item ripple color.
Style
<style name="AppTheme" parent="Theme.AppCompat.Light.NoActionBar">
<item name="colorPrimary">#ffffff</item>
</style>

setSupportActionBar((Toolbar) findViewById(R.id.toolbar));
}
#Override
public boolean onCreateOptionsMenu(Menu menu) {
getMenuInflater().inflate(R.menu.menu_notifications, menu);
return true;
}

In your styles:
<style name="MyToolbarTheme" parent="#style/ThemeOverlay.AppCompat.Light">
<item name="colorControlHighlight">#color/colorAccent</item>
</style>
Apply this theme to your toolbar:
<android.support.v7.widget.Toolbar
android:id="#+id/toolbar"
android:layout_width="match_parent"
android:layout_height="wrap_content"
app:popupTheme="#style/MyToolbarTheme"/>
Result:
EDIT
For the action item:
<style name="MyAppBarLayoutTheme" parent="#style/ThemeOverlay.AppCompat.Dark.ActionBar">
<item name="colorControlHighlight">#color/colorAccent</item>
</style>
<android.support.design.widget.AppBarLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:theme="#style/MyAppBarLayoutTheme">
<android.support.v7.widget.Toolbar/>
</android.support.design.widget.AppBarLayout>
Result:

Even I faced similar issue due to AppTheme. I was using Theme.MaterialComponents.NoActionBar as default theme for App and only for toolbar the ripple effect was not working. However I solved it using app:theme.
Please try adding a app:theme="#style/Theme.AppCompat.Light.NoActionBar" to your toolbar. This is test with androidx.appcompat.widget.Toolbar it is working for me.
<androidx.appcompat.widget.Toolbar
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="?attr/actionBarSize"
android:background="#android:color/white"
app:layout_collapseMode="pin"
android:elevation="4dp"
app:theme="#style/Theme.AppCompat.Light.NoActionBar"
android:stateListAnimator="#animator/appbar_elevation"
tools:targetApi="lollipop">
If your view doesn't ripple by default then, all you have to do is add android:background="?attr/selectableItemBackground" to your view to get that ripple/touch effect.
<ImageView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="center"
android:background="?attr/selectableItemBackground"
android:contentDescription="#null"
android:src="#mipmap/ic_launcher" />

Find the file named styles.xml in your res folder.
You should have defined a theme for your project which looks something like below code
<style name="AppTheme" parent="Theme.AppCompat.Light.DarkActionBar">
<!-- Customize your theme here. -->
<item name="colorPrimary">#color/text_description</item>
<item name="colorPrimaryDark">#color/black</item>
<item name="colorAccent">#color/theme_teal</item>
</style>
Here, colorPrimary defines the color of your actionBar. This color must have been set to blue acc to the screenshot.
Try changing the colorPrimary value to the desired color that you want.

Change style.xml:
<item name="colorPrimary">#color/colorPrimary</item>
to :
<item name="colorPrimary">#android:color/holo_red_dark</item>

text in the tablayout is not show correctly

I have a 11 Fragment in the viewPager, and when tablayout want to show these 11 fragment name , their text not show correctly.

and I set this on my tablayout in the MainActivity.java but still i have a problem :
appTabLayout.setTabGravity(TabLayout.GRAVITY_FILL);

try to use like that
<android.support.design.widget.TabLayout
android:id="#+id/xmlTabLayoutMain"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_below="#+id/xmlToolbarMain"
android:background="?attr/colorPrimary"
android:elevation="8dp"
app:tabMode="scrollable"
android:minHeight="?attr/actionBarSize"
android:theme="#style/ThemeOverlay.AppCompat.Dark.ActionBar"/>
also try to use if not working
app:tabGravity="fill"
tabMode will make your tab scrollable.So it should solve your problem.

You could create a custom style for your text and there define all the constraints like normal text view attributes. then just set tab text appearance to your custom style.
Your tab layout will be like -
<android.support.design.widget.TabLayout
android:id="#+id/tabs_home"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:background="?attr/colorPrimary"
app:tabTextAppearance="#style/MineCustomTabText"
app:tabMode="scrollable"
/>
And in your style.xml file define the style, like this -
<style name="MineCustomTabText" parent="TextAppearance.Design.Tab">
<item name="android:textSize">16sp</item>
<item name="android:maxLines">1</item>
</style>
