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;
}

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);
            }

        }
    });
}

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);
    }

这是你如何用颜色给一个特定的菜单项上色，适用于所有API级别:

public static void setToolbarMenuItemTextColor(final Toolbar toolbar,
                                               final @ColorRes int color,
                                               @IdRes final int resId) {
    if (toolbar != null) {
        for (int i = 0; i < toolbar.getChildCount(); i++) {
            final View view = toolbar.getChildAt(i);
            if (view instanceof ActionMenuView) {
                final ActionMenuView actionMenuView = (ActionMenuView) view;
                // view children are accessible only after layout-ing
                actionMenuView.post(new Runnable() {
                    @Override
                    public void run() {
                        for (int j = 0; j < actionMenuView.getChildCount(); j++) {
                            final View innerView = actionMenuView.getChildAt(j);
                            if (innerView instanceof ActionMenuItemView) {
                                final ActionMenuItemView itemView = (ActionMenuItemView) innerView;
                                if (resId == itemView.getId()) {
                                    itemView.setTextColor(ContextCompat.getColor(toolbar.getContext(), color));
                                }
                            }
                        }
                    }
                });
            }
        }
    }
}

通过这样做，你会失去背景选择器的效果，所以下面的代码将一个自定义的背景选择器应用到所有菜单项的子项上。

public static void setToolbarMenuItemsBackgroundSelector(final Context context,
                                                         final Toolbar toolbar) {
    if (toolbar != null) {
        for (int i = 0; i < toolbar.getChildCount(); i++) {
            final View view = toolbar.getChildAt(i);
            if (view instanceof ImageButton) {
                // left toolbar icon (navigation, hamburger, ...)
                UiHelper.setViewBackgroundSelector(context, view);
            } else if (view instanceof ActionMenuView) {
                final ActionMenuView actionMenuView = (ActionMenuView) view;

                // view children are accessible only after layout-ing
                actionMenuView.post(new Runnable() {
                    @Override
                    public void run() {
                        for (int j = 0; j < actionMenuView.getChildCount(); j++) {
                            final View innerView = actionMenuView.getChildAt(j);
                            if (innerView instanceof ActionMenuItemView) {
                                // text item views
                                final ActionMenuItemView itemView = (ActionMenuItemView) innerView;
                                UiHelper.setViewBackgroundSelector(context, itemView);

                                // icon item views
                                for (int k = 0; k < itemView.getCompoundDrawables().length; k++) {
                                    if (itemView.getCompoundDrawables()[k] != null) {
                                        UiHelper.setViewBackgroundSelector(context, itemView);
                                    }
                                }
                            }
                        }
                    }
                });
            }
        }
    }
}

下面是helper函数:

public static void setViewBackgroundSelector(@NonNull Context context, @NonNull View itemView) {
    int[] attrs = new int[]{R.attr.selectableItemBackgroundBorderless};
    TypedArray ta = context.obtainStyledAttributes(attrs);
    Drawable drawable = ta.getDrawable(0);
    ta.recycle();

    ViewCompat.setBackground(itemView, drawable);
}

将它添加到我的styles.xml中对我有用

<item name="android:textColorPrimary">?android:attr/textColorPrimaryInverse</item>
