Set font style bold of appcompat toolbar menu

Question

My menu items becomes red, 10sp and the background is white but textStyle bold is not working. Why is this?

styles.xml

<style name="toolbarMenuTheme">
    <item name="android:colorBackground">@color/white</item>
    <item name="android:textColor">@color/red</item>
    <item name="android:textSize">10sp</item>
    <item name="android:textStyle">bold</item>
</style>

Snippet from my layout.

    <android.support.v7.widget.Toolbar xmlns:android="http://schemas.android.com/apk/res/android"
        android:id="@+id/toolbar"
        android:layout_width="match_parent"
        android:layout_height="48dp"
        android:layout_marginTop="-5dp"
        android:background="@color/white"
        android:theme="@style/toolbarMenuTheme"/>

And my inflated layout.

<item
    android:id="@+id/web_view_reload"
    android:icon="@drawable/replay"
    android:title="Reload"
    app:showAsAction="always"/>
<item
    android:id="@+id/web_view_action"
    android:icon="@drawable/stack_icon_on"
    android:title="Stack"
    app:showAsAction="always"/>
<item
    android:id="@+id/web_view_screenshot"
    android:icon="@drawable/screenshot"
    android:title="Screenshot"
    app:showAsAction="always"/>
<item
    android:id="@+id/web_view_share"
    android:title="SHARE WEBSITE"/>
<item
    android:id="@+id/web_view_copy_url"
    android:title="Copy URL"/>

Inflating it in java by:

    Toolbar toolbar = (Toolbar) view.findViewById(R.id.toolbar);
    toolbar.setNavigationIcon(R.drawable.x);
    toolbar.inflateMenu(R.menu.web_view_toolbar_menu);

And setting click listeners:

toolbar.setOnMenuItemClickListener(new Toolbar.OnMenuItemClickListener() {
    @Override
    public boolean onMenuItemClick(MenuItem item) {
        ....
    }
}

Answer 1

Add the following in your styles.xml file

<style name="ActionBar.nameText" parent="TextAppearance.AppCompat.Widget.ActionBar.Title">
        <item name="android:textColor">@color/PrimaryTextColor</item>
        <item name="android:textSize">18sp</item>
        <item name="android:textStyle">bold</item>
    </style>

The style name and parent might differ in your case, but take concept for bold

EDIT

Use the following in the toolbar.xml

    <android.support.v7.widget.Toolbar
    xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:companyApp="http://schemas.android.com/apk/res-auto"
    android:layout_width="match_parent"
    android:layout_height="?actionBarSize"
    companyApp:theme="@style/ActionBarThemeOverlay"
    companyApp:titleTextAppearance="@style/ActionBar.nameText">
</android.support.v7.widget.Toolbar>

And in your styles.xml

<style name="ActionBarThemeOverlay" parent="">
        <item name="android:textColorPrimary">@color/PrimaryTextColor</item>
        <item name="colorControlHighlight">@color/BackgroundColor</item>
        <item name="android:actionMenuTextColor">@color/PrimaryTextColor</item>
        <item name="android:textColorSecondary">@color/PrimaryTextColor</item>
        <item name="android:background">@color/PrimaryBackgroundColor</item>
    </style>

And in the androidmanifest.xml

<application
   android:icon="@drawable/ic_launcher"
   android:label="@string/app_name" 
   android:theme="@android:style/Your Theme">

Answer 2

Why not to try this

Also in this you can set parts of text bold

Screenshot

getSupportActionBar().setDisplayShowTitleEnabled(true);
SpannableStringBuilder str = new SpannableStringBuilder("HelloWorld");
str.setSpan(new android.text.style.StyleSpan(android.graphics.Typeface.BOLD), 5, 10,Spannable.SPAN_EXCLUSIVE_EXCLUSIVE);
getSupportActionBar().setTitle(str);

Output will be HelloWorld

In case you want your whole text to be bold, just use this

str.setSpan(new android.text.style.StyleSpan(android.graphics.Typeface.BOLD), 0, 10,Spannable.SPAN_EXCLUSIVE_EXCLUSIVE);

Output will be HelloWorld
