我可以改变一个菜单项的背景颜色在安卓?

如果有人对此有任何解决方案,请让我知道。最后一个选项显然是自定义,但是否有任何方法可以在不自定义的情况下更改文本颜色。

主题中的一句话:)

<item name="android:actionMenuTextColor">@color/your_color</item>

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。

如果你使用的菜单是<android.support.design.widget.NavigationView />,那么只需在NavigationView中添加以下一行:

app:itemTextColor="your color"

也可用colorTint图标,它将覆盖颜色为您的图标以及。为此,你必须添加以下一行:

app:itemIconTint="your color"

例子:

<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:itemTextColor="@color/color_white"
        app:itemIconTint="@color/color_white"

        android:background="@color/colorPrimary"
        android:fitsSystemWindows="true"
        app:headerLayout="@layout/nav_header_main"
        app:menu="@menu/activity_main_drawer"/>

希望对你有所帮助。

Options menu in android can be customized to set the background or change the text appearance. The background and text color in the menu couldn’t be changed using themes and styles. The android source code (data\res\layout\icon_menu_item_layout.xml)uses a custom item of class “com.android.internal.view.menu.IconMenuItem”View for the menu layout. We can make changes in the above class to customize the menu. To achieve the same, use LayoutInflater factory class and set the background and text color for the view.


@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);
}


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;
}

最简单的方法为单个工具栏定制菜单颜色,而不是为AppTheme

    <android.support.design.widget.AppBarLayout
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:theme="@style/AppTheme.AppBarOverlay.MenuBlue">
        <android.support.v7.widget.Toolbar
            android:id="@+id/toolbar"
            android:layout_width="match_parent"
            android:layout_height="?attr/actionBarSize"/>
    </android.support.design.widget.AppBarLayout>

xml上常用的工具栏

<style name="AppTheme.AppBarOverlay" parent="ThemeOverlay.AppCompat.Dark.ActionBar"/>

自定义工具栏样式

<style name="AppTheme.AppBarOverlay.MenuBlue">
    <item name="actionMenuTextColor">@color/blue</item>
</style>
