API 21测试

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);
    }

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。

我的情况是在选项菜单中设置文本颜色(主应用程序菜单显示在菜单按钮按下)。

在API 16中测试，使用AppCompat -v7-27.0.2库，MainActivity的AppCompat活动和AndroidManifest.xml应用程序的AppCompat主题。

styles.xml:

<style name="AppTheme" parent="Theme.AppCompat.Light.DarkActionBar">
  <item name="actionBarPopupTheme">@style/PopupTheme</item>
</style>

<style name="PopupTheme" parent="@style/ThemeOverlay.AppCompat.Light">
  <item name="android:textColorSecondary">#f00</item>
</style>

不知道textColorSecondary是否影响其他元素，但它控制菜单文本的颜色。

我搜索了一些关于这个主题的示例，但所有现成的代码片段都不起作用。

所以我想用appcompat-v7库的源代码(特别是.aar包的res文件夹)来研究它。

不过在我的例子中，我使用了带有爆炸性.aar依赖项的Eclipse。因此，我可以更改默认样式并检查结果。不知道如何爆炸库与Gradle或Android Studio直接使用。它值得进行另一项调查。

所以我的目的是找到res/values/values.xml文件中用于菜单文本的颜色(我几乎确定颜色在那里)。

I opened that file, then duplicated all colors, put them below the default ones to override them and assigned #f00 value to all of them. Start the app. Many elements had red background or text color. And the menu items too. That was what I needed. Removing my added colors by blocks of 5-10 lines I ended with the secondary_text_default_material_light color item. Searching that name in the files within the res folder (or better within res/colors) I found only one occurrence in the color/abc_secondary_text_material_light.xml file (I used Sublime Text for these operations so it's easier to find thing I need). Back to the values.xml 8 usages were found for the @color/abc_secondary_text_material_light. It was a Light theme so 4 left in 2 themes: Base.ThemeOverlay.AppCompat.Light and Platform.AppCompat.Light. The first theme was a child of the second one so there were only 2 attributes with that color resource: android:textColorSecondary and android:textColorTertiaryin the Base.ThemeOverlay.AppCompat.Light. Changing their values directly in the values.xml and running the app I found that the final correct attribute was android:textColorSecondary. Next I needed a theme or another attribute so I could change it in my app's style.xml (because my theme had as the parent the Theme.AppCompat.Light and not the ThemeOverlay.AppCompat.Light). I searched in the same file for the Base.ThemeOverlay.AppCompat.Light. It had a child ThemeOverlay.AppCompat.Light. Searching for the ThemeOverlay.AppCompat.Light I found its usage in the Base.Theme.AppCompat.Light.DarkActionBar theme as the actionBarPopupTheme attribute value. My app's theme Theme.AppCompat.Light.DarkActionBar was a child of the found Base.Theme.AppCompat.Light.DarkActionBar so I could use that attribute in my styles.xml without problems. As it's seen in the example code above I created a child theme from the mentioned ThemeOverlay.AppCompat.Light and changed the android:textColorSecondary attribute.

我找到了，尤利卡!!

在你的应用主题中:

<style name="AppTheme" parent="Theme.AppCompat.Light.DarkActionBar">
    <item name="android:actionBarStyle">@style/ActionBarTheme</item>
    <!-- backward compatibility -->          
    <item name="actionBarStyle">@style/ActionBarTheme</item>        
</style>

这是你的动作栏主题:

<style name="ActionBarTheme" parent="@style/Widget.AppCompat.Light.ActionBar.Solid.Inverse">
   <item name="android:background">@color/actionbar_bg_color</item>
   <item name="popupTheme">@style/ActionBarPopupTheme</item
   <!-- backward compatibility -->
   <item name="background">@color/actionbar_bg_color</item>
</style>

这是你弹出的主题:

 <style name="ActionBarPopupTheme">
    <item name="android:textColor">@color/menu_text_color</item>
    <item name="android:background">@color/menu_bg_color</item>
 </style>

干杯,)

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)
