main_activity.xml

<android.support.design.widget.NavigationView
      android:id="@+id/nav_view"
      android:layout_width="wrap_content"
      android:layout_height="match_parent"
      android:layout_gravity="start"
      app:itemTextAppearance="@style/TextAppearance.SideManu"
      android:fitsSystemWindows="true"
      app:headerLayout="@layout/nav_header_main"
      app:menu="@menu/activity_main_drawer" />

我想改变＆＃34;沟通＆＃34;的字体。以及旁边的菜单。我成功更改了所有项目的字体。但实际上我无法改变＆＃34;沟通＆＃34;仅限文字。

将此课程添加到您的项目

public class CustomTypefaceSpan extends TypefaceSpan {

    private final Typeface newType;

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

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

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

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

        paint.setTypeface(tf);
    }

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

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

将此方法添加到您的活动

private void applyFontToMenuItem(MenuItem mi) {
        Typeface font = Typeface.createFromAsset(getAssets(), "fonts/aguafina_script.ttf");
        SpannableString mNewTitle = new SpannableString(mi.getTitle());
        mNewTitle.setSpan(new CustomTypefaceSpan("" , font), 0 , mNewTitle.length(),  Spannable.SPAN_INCLUSIVE_INCLUSIVE);
        mi.setTitle(mNewTitle);
}

并在你的onCreate：

 @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_test);
        NavigationView navView = (NavigationView) findViewById(R.id.nav_view);
        Menu m = navView.getMenu();
        for (int i = 0; i < m.size(); i++) {
            MenuItem mi = m.getItem(i);

            //for aapplying a font to subMenu ...
            SubMenu subMenu = mi.getSubMenu();
            if (subMenu != null && subMenu.size() > 0) {
                for (int j = 0; j < subMenu.size(); j++) {
                    MenuItem subMenuItem = subMenu.getItem(j);
                    applyFontToMenuItem(subMenuItem);
                }
            }

            //the method we have create in activity
            applyFontToMenuItem(mi);
        }
    }

这是你想要的输出
