试试这段代码....

 @Override
    public boolean onCreateOptionsMenu(Menu menu) {
        MenuInflater inflater = getMenuInflater();
         inflater.inflate(R.menu.my_menu, menu);

        getLayoutInflater().setFactory(new Factory() {
            @Override
            public View onCreateView(String name, Context context,
                    AttributeSet attrs) {

                if (name.equalsIgnoreCase("com.android.internal.view.menu.IconMenuItemView")) {
                    try {
                        LayoutInflater f = getLayoutInflater();
                        final View view = f.createView(name, null, attrs);

                        new Handler().post(new Runnable() {
                            public void run() {

                                // set the background drawable
                                 view.setBackgroundResource(R.drawable.my_ac_menu_background);

                                // set the text color
                                ((TextView) view).setTextColor(Color.WHITE);
                            }
                        });
                        return view;
                    } catch (InflateException e) {
                    } catch (ClassNotFoundException e) {
                    }
                }
                return null;
            }
        });
        return super.onCreateOptionsMenu(menu);
    }

通过使用SpannableString而不是String，您可以轻松地更改菜单项文本的颜色。

@Override
public void onCreateOptionsMenu(Menu menu, MenuInflater inflater) {
    inflater.inflate(R.menu.your_menu, menu);

    int positionOfMenuItem = 0; // or whatever...
    MenuItem item = menu.getItem(positionOfMenuItem);
    SpannableString s = new SpannableString("My red MenuItem");
    s.setSpan(new ForegroundColorSpan(Color.RED), 0, s.length(), 0);
    item.setTitle(s);
}

感谢您提供的代码示例。 我不得不修改它，让它与上下文菜单一起工作。 这就是我的解。

    static final Class<?>[] constructorSignature = new Class[] {Context.class, AttributeSet.class};

class MenuColorFix implements LayoutInflater.Factory {
    public View onCreateView(String name, Context context, AttributeSet attrs) {
        if (name.equalsIgnoreCase("com.android.internal.view.menu.ListMenuItemView")) {
            try {
                Class<? extends ViewGroup> clazz = context.getClassLoader().loadClass(name).asSubclass(ViewGroup.class);
                Constructor<? extends ViewGroup> constructor = clazz.getConstructor(constructorSignature);
                final ViewGroup view = constructor.newInstance(new Object[]{context,attrs});

                new Handler().post(new Runnable() {
                    public void run() {
                        try {
                            view.setBackgroundColor(Color.BLACK);
                            List<View> children = getAllChildren(view);
                            for(int i = 0; i< children.size(); i++) {
                                View child = children.get(i);
                                if ( child instanceof TextView ) {
                                    ((TextView)child).setTextColor(Color.WHITE);
                                }
                            }
                        }
                        catch (Exception e) {
                            Log.i(TAG, "Caught Exception!",e);
                        }

                    }
                });
                return view;
            }
            catch (Exception e) {
                Log.i(TAG, "Caught Exception!",e);
            }
        }
        return null;
    }       
}

public List<View> getAllChildren(ViewGroup vg) {
    ArrayList<View> result = new ArrayList<View>();
    for ( int i = 0; i < vg.getChildCount(); i++ ) {
        View child = vg.getChildAt(i);
        if ( child instanceof ViewGroup) {
            result.addAll(getAllChildren((ViewGroup)child));
        }
        else {
            result.add(child);
        }
    }
    return result;
}

@Override
public void onCreateContextMenu(ContextMenu menu, View v, ContextMenuInfo menuInfo) {
    LayoutInflater lInflater = getLayoutInflater();
    if ( lInflater.getFactory() == null ) {
        lInflater.setFactory(new MenuColorFix());
    }
    super.onCreateContextMenu(menu, v, menuInfo);
    MenuInflater inflater = getMenuInflater();
    inflater.inflate(R.menu.myMenu, menu);
}

对我来说，这适用于Android 1.6、2.03和4.03。

您可以通过编程方式设置颜色。

private static void setMenuTextColor(final Context context, final Toolbar toolbar, final int menuResId, final int colorRes) {
    toolbar.post(new Runnable() {
        @Override
        public void run() {
            View settingsMenuItem =  toolbar.findViewById(menuResId);
            if (settingsMenuItem instanceof TextView) {
                if (DEBUG) {
                    Log.i(TAG, "setMenuTextColor textview");
                }
                TextView tv = (TextView) settingsMenuItem;
                tv.setTextColor(ContextCompat.getColor(context, colorRes));
            } else { // you can ignore this branch, because usually there is not the situation
                Menu menu = toolbar.getMenu();
                MenuItem item = menu.findItem(menuResId);
                SpannableString s = new SpannableString(item.getTitle());
                s.setSpan(new ForegroundColorSpan(ContextCompat.getColor(context, colorRes)), 0, s.length(), 0);
                item.setTitle(s);
            }

        }
    });
}

当菜单项膨胀时，我使用html标记来更改单个项目的文本颜色。希望对大家有所帮助。

public boolean onCreateOptionsMenu(Menu menu) {
    // Inflate the menu; this adds items to the action bar if it is present.
    getMenuInflater().inflate(R.menu.menu_main, menu);
    menu.findItem(R.id.main_settings).setTitle(Html.fromHtml("<font color='#ff3824'>Settings</font>"));
    return true;
}

在Kotlin中我写了这些扩展:

fun MenuItem.setTitleColor(color: Int) {
    val hexColor = Integer.toHexString(color).toUpperCase().substring(2)
    val html = "<font color='#$hexColor'>$title</font>"
    this.title = html.parseAsHtml()
}           



@Suppress("DEPRECATION")                                                                        
fun String.parseAsHtml(): Spanned {                                                             
    return if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.N) {                                
        Html.fromHtml(this, Html.FROM_HTML_MODE_LEGACY)                                         
    } else {                                                                                    
        Html.fromHtml(this)                                                                     
    }                                                                                           
}  

并像这样使用:

menu.findItem(R.id.main_settings).setTitleColor(Color.RED)
