我在 10 英寸设备中的输出低于

在此处输入图像描述

在 4.7 英寸设备中，它显示输出（如果 #404040 颜色代码，则使用白色文本颜色）

在此处输入图像描述

在这里，我可以设置背景颜色，但菜单项文本颜色在 4.7 英寸设备中没有改变

在 4.7 英寸设备中，我没有溢出菜单图标，我通过按菜单按钮打开此菜单。

如何设置文本颜色与 10 英寸设备相同？

提前谢谢！！！

我的菜单布局代码是：

您应该能够通过使用SpannableString而不是轻松更改文本的颜色String- 不需要肮脏的解决方法;-)

SpannableString s = new SpannableString("My red MenuItem");
s.setSpan(new ForegroundColorSpan(Color.RED), 0, s.length(), 0);
item.setTitle(s);

我通过检查设备版本通过菜单代码更改背景颜色来解决。

如果设备不支持溢出菜单，您可以更改菜单的背景颜色，也可以使用以下方法更改菜单文本颜色：

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.GRAY);
                        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.BLACK);
                            }
                        }
                    }
                    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;
}

//并在onCreateContextMenu中，放置以下代码

@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);
}
