with the following attribute

<pre><code>&lt;android.support.design.internal.NavigationMenuItemView

Which meant all we had to do was to override the <code>textAppearanceListItem</code> style in our project.

 &lt;item name="textAppearanceListItem"&gt;@style/list_item_appearance&lt;/item&gt;

I'm not totally sure what else this will affect but if anyone has a better answer I'd be happy to accept that instead!

blocks|key|357496|text|自从Android+22.2.1以来，谷歌已经将NavigationView中条目的默认NavigationView从16+to更改为14+to，这很符合材料设计准则。但是，在某些情况下(例如，当您想支持中文时)，更大的textSize似乎更好。解决办法很简单：|type|unstyled|depth|inlineStyleRanges|offset|length|style|CODE|entityRanges|data|357497|将app:theme="@style/yourStyle.Drawer"添加到layout.xml中的NavigationView中|ordered-list-item|357498|在styles.xml中，在样式yourStyle.Drawer中添加android:textSize="16sp"|357499|entityMap^0|O|E|18|E|0|1|Z|1F|E|0|G|G|Z|N|0^^$0|@$1|2|3|4|5|6|7|M|8|@$9|N|A|O|B|C]|$9|P|A|Q|B|C]]|D|@]|E|$]]|$1|F|3|G|5|H|7|R|8|@$9|S|A|T|B|C]|$9|U|A|V|B|C]]|D|@]|E|$]]|$1|I|3|J|5|H|7|W|8|@$9|X|A|Y|B|C]|$9|Z|A|10|B|C]]|D|@]|E|$]]|$1|K|3|-4|5|6|7|11|8|@]|D|@]|E|$]]]|L|$]]

Since Android Support Library 22.2.1, Google has changed default textSize of items in <code>NavigationView</code> from 16sp to 14sp, which suits Material Design guideline well. However, in some cases(for example, when you want to support Chinese language), it seems larger textSize is better. Solution is simple:

<ol>
<li>add <code>app:theme="@style/yourStyle.Drawer"</code> to your <code>NavigationView</code> in your layout.xml</li>
<li>in styles.xml, add <code>android:textSize="16sp"</code> in style <code>yourStyle.Drawer</code></li>
</ol>

 &lt;item name="android:listPreferredItemPaddingRight"&gt;8dp&lt;/item&gt;
 &lt;item name="listPreferredItemPaddingRight"&gt;8dp&lt;/item&gt;
 &lt;/style&gt;
</code></pre>

Add it to your <code>main_layout.xml</code>

<pre><code> &lt;android.support.design.widget.NavigationView
 ...
 app:theme="@style/NavigationDrawerStyle"
 ....&gt;


 &lt;/android.support.design.widget.NavigationView&gt;
</code></pre>

All params of the navigation items (which you can change) are located here (path to file <code>...\sdk\extras\android\support\design\res\layout\design_navigation_item.xml</code> ) 

<code>design_navigation_item.xml</code> 

<pre><code>&lt;android.support.design.internal.NavigationMenuItemView

 android:layout_width="match_parent"
 android:layout_height="?attr/listPreferredItemHeightSmall"

 android:gravity="center_vertical|start"
 android:maxLines="1"
 android:fontFamily="sans-serif-thin"
 android:textSize="22sp"
 android:textAppearance="?attr/textAppearanceListItem" /&gt;
</code></pre>

Also you can override <code>*.xml</code> file (copy file from <code>...\sdk\extras\android\support\design\res\layout\design_navigation_item.xml</code>), just in your <code>app/src/main/res/layout</code> folder create a layout named the same <code>design_navigation_item.xml</code>. 

All layouts which can be Overriden are located here <code>...\sdk\extras\android\support\design\res\layout\</code>

<pre><code>design_layout_snackbar.xml
design_layout_snackbar_include.xml
design_layout_tab_icon.xml
design_layout_tab_text.xml
design_navigation_item.xml
design_navigation_item_header.xml
design_navigation_item_separator.xml
design_navigation_item_subheader.xml
design_navigation_menu.xml
</code></pre>

[UPDATE] Each version of <code>com.android.support:design-{version}</code> lib has different items to override. 
Check all what you need in 

<a href="https://i.stack.imgur.com/JI4oi.png" rel="noreferrer"><img src="https://i.stack.imgur.com/JI4oi.png" alt="enter image description here"></a>

[UPDATE 04/14/2020]

If you are using <code>com.google.android.material.navigation.NavigationView</code>
then open the class, and you will see:

<pre><code>public NavigationView(@NonNull Context context, @Nullable AttributeSet attrs) {
 this(context, attrs, R.attr.navigationViewStyle);
 }
</code></pre>

So you can use attr <code>navigationViewStyle</code> to set your own style for the NavigationView via theme of your app:

NB: parent theme of AppTheme should be <code>Theme.MaterialComponents</code>

<pre><code> &lt;style name="AppTheme" parent="Theme.MaterialComponents.Light.NoActionBar.Bridge"&gt;
 ...
&lt;item name="navigationViewStyle"&gt;@style/AppNavigationViewStyle&lt;/item&gt;
 ...
 &lt;/style&gt;

&lt;style name="AppNavigationViewStyle" parent="Widget.MaterialComponents.NavigationView"&gt;
 &lt;item name="itemTextAppearance"&gt;@style/AppNavigationViewItemTextAppearance&lt;/item&gt;
 &lt;/style&gt;
&lt;style name="AppNavigationViewItemTextAppearance" parent="@style/TextAppearance.MaterialComponents.Subtitle2"&gt;
 &lt;item name="android:textSize"&gt;18sp&lt;/item&gt;
 &lt;/style&gt;
</code></pre>

Just open parent theme to see all <code>&lt;item name</code> attrs for override

blocks|key|1502756|text|可以在xml文件中使用此属性。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1502757|app:itemTextAppearance="?android:attr/textAppearanceMedium"|code-block|syntax|javascript|1502758|或用于小文本|1502759|app:itemTextAppearance="?android:attr/textAppearance"|1502760|或者大的文本|1502761|app:itemTextAppearance="?android:attr/textAppearanceLarge"|1502762|entityMap^0|0|0|0|0|0|0^^$0|@$1|2|3|4|5|6|7|Q|8|@]|9|@]|A|$]]|$1|B|3|C|5|D|7|R|8|@]|9|@]|A|$E|F]]|$1|G|3|H|5|6|7|S|8|@]|9|@]|A|$]]|$1|I|3|J|5|D|7|T|8|@]|9|@]|A|$E|F]]|$1|K|3|L|5|6|7|U|8|@]|9|@]|A|$]]|$1|M|3|N|5|D|7|V|8|@]|9|@]|A|$E|F]]|$1|O|3|-4|5|6|7|W|8|@]|9|@]|A|$]]]|P|$]]

you can use this attributes inside xml file

<pre><code>app:itemTextAppearance="?android:attr/textAppearanceMedium"

or for small text

<pre><code>app:itemTextAppearance="?android:attr/textAppearance"

or for large text

<pre><code>app:itemTextAppearance="?android:attr/textAppearanceLarge"
</code></pre>

blocks|key|1502783|text|也许能帮上忙。最近，我不得不用编程的方式来做这件事。我用过这门课：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1502784|public+class+CustomTypefaceSpan+extends+TypefaceSpan+{

private+final+Typeface+newType;
private+final+float+newSp;

};
}|code-block|syntax|javascript|1502785|然后我就这样用了：|1502786|//+This+is+for+color

}
item.setTitle(s);|1502787|希望这能有所帮助。|1502788|entityMap^0|0|0|0|0|0^^$0|@$1|2|3|4|5|6|7|O|8|@]|9|@]|A|$]]|$1|B|3|C|5|D|7|P|8|@]|9|@]|A|$E|F]]|$1|G|3|H|5|6|7|Q|8|@]|9|@]|A|$]]|$1|I|3|J|5|D|7|R|8|@]|9|@]|A|$E|F]]|$1|K|3|L|5|6|7|S|8|@]|9|@]|A|$]]|$1|M|3|-4|5|6|7|T|8|@]|9|@]|A|$]]]|N|$]]

Maybe it might help. Recently I had to do this programmatically.
I used this class:

<pre><code>public class CustomTypefaceSpan extends TypefaceSpan {

private final Typeface newType;
private final float newSp;

public CustomTypefaceSpan(String family, Typeface type, float sp) {
 super(family);
 newType = type;
 newSp = sp;
}

@Override
public void updateDrawState(TextPaint ds) {
 applyCustomTypeFace(ds, newType, newSp);
}

@Override
public void updateMeasureState(TextPaint paint) {
 applyCustomTypeFace(paint, newType, newSp);
}

private static void applyCustomTypeFace(Paint paint, Typeface tf, float sp) {
 int oldStyle;
 Typeface old = paint.getTypeface();
 if (old == null) {
 oldStyle = 0;
 } else {
 oldStyle = old.getStyle();
 }

 int fake = oldStyle &amp; ~tf.getStyle();
 if ((fake &amp; Typeface.BOLD) != 0) {
 paint.setFakeBoldText(true);
 }

 if ((fake &amp; Typeface.ITALIC) != 0) {
 paint.setTextSkewX(-0.25f);
 }

 paint.setTextSize(sp);
 paint.setTypeface(tf);
}

@SuppressWarnings("unused")
public static final Parcelable.Creator&lt;CustomTypefaceSpan&gt; CREATOR = new Parcelable.Creator&lt;CustomTypefaceSpan&gt;() {
 @Override
 public CustomTypefaceSpan createFromParcel(Parcel in) {
 return null;
 }

 @Override
 public CustomTypefaceSpan[] newArray(int size) {
 return new CustomTypefaceSpan[size];
 }
};
}
</code></pre>

Then I used like this:

<pre><code>// This is for color
SpannableString s = new SpannableString(item.getTitle().toString());
 s.setSpan(new ForegroundColorSpan(Color.RED), 0, s.length(), 0);

// This is for typeface and size
Typeface typeFace = Functions.getTypeface(this, "Avenir");

if (typeFace != null) {
 int size = 19;
 float scaledSizeInPixels = size * getResources().getDisplayMetrics().scaledDensity;
 CustomTypefaceSpan spanTypeFace = new CustomTypefaceSpan(item.getTitle().toString(), typeFace, scaledSizeInPixels);
 s.setSpan(spanTypeFace, 0, s.length(), 0);
}
item.setTitle(s);
</code></pre>

Hope this helps.

blocks|key|1502848|text|在设计中选择itemTextAppearance+activity_main.xml并选择nav_view，您可以通过更新nav_view和itemTextColor来更改菜单项文本大小，如下所示|type|unstyled|depth|inlineStyleRanges|offset|length|style|BOLD|entityRanges|data|1502849|📷|atomic|1502850|​|1502851|entityMap|0|IMAGE|mutability|IMMUTABLE|imageUrl|https://developer.qcloudimg.com/http-save/yehe-900000/8cf928e819c4b40972e531688be56016.png|imageAlt^0|6|I|1Y|D|0|0|1|0|0|0^^$0|@$1|2|3|4|5|6|7|T|8|@$9|U|A|V|B|C]|$9|W|A|X|B|C]]|D|@]|E|$]]|$1|F|3|G|5|H|7|Y|8|@]|D|@$9|Z|A|10|1|11]]|E|$]]|$1|I|3|J|5|6|7|12|8|@]|D|@]|E|$]]|$1|K|3|-4|5|6|7|13|8|@]|D|@]|E|$]]]|L|$M|$5|N|O|P|E|$Q|R|S|-4]]]]

Goto activity_main.xml and select nav_view in design and you can change menu item text size by updating itemTextAppearance and itemTextColor like as follows

blocks|key|357598|text|对于com.google.android.material.navigation.NavigationView，您应该使用带有自定义样式的app命名空间：app:itemTextAppearance="@style/NavDrawerTextStyle"|type|unstyled|depth|inlineStyleRanges|offset|length|style|CODE|BOLD|entityRanges|data|357599|entityMap^0|2|1H|25|1E|1X|3|0^^$0|@$1|2|3|4|5|6|7|I|8|@$9|J|A|K|B|C]|$9|L|A|M|B|C]|$9|N|A|O|B|D]]|E|@]|F|$]]|$1|G|3|-4|5|6|7|P|8|@]|E|@]|F|$]]]|H|$]]

For <code>com.google.android.material.navigation.NavigationView</code> you should use the app namespace with your custom style:
<code>app:itemTextAppearance=&quot;@style/NavDrawerTextStyle&quot;</code>

Google <a href="http://android-developers.blogspot.com.au/2015/05/android-design-support-library.html">recently released</a> the <code>android.support.design.widget.NavigationView</code> widget as part of the <code>com.android.support:design:22.2.0</code> library, which greatly simplified (and standardises) the process of creating a NavigationDrawer.

However according to the <a href="http://www.google.com/design/spec/patterns/navigation-drawer.html#navigation-drawer-specs">design specs</a>, the list item should be Roboto Medium, 14sp, 87% #000000. The <code>NavigationView</code> exposes no <code>textSize</code> or <code>textStyle</code> to customise this.

<img src="https://i.stack.imgur.com/vAZfD.png" alt="Material design specs">
<img src="https://i.stack.imgur.com/iDGcJ.png" alt="Font style info">

What are my options if I'm pedantic about maintaining the correct design specifications using the Google provided <code>NavigationView</code> (or customising it in any other way)?

How can I change the NavigationView's item text size?
