How can I change the Options menu background for Android 2.3?
提问by SpicyWeenie
I have the same standard options menu, but I want to change the background of the items from white to black. I've seen many postings about how to do it, but those don't work for 2.3.
我有相同的标准选项菜单，但我想将项目的背景从白色更改为黑色。我看过很多关于如何做的帖子，但那些不适用于 2.3。
Does anyone know of a working menu inflater with a custom-colored background compatible with version 2.3?
有谁知道具有与 2.3 版兼容的自定义颜色背景的工作菜单充气器？
**ATTENTION**NO IMAGE PLACEMENT!!! NO CODE FROM OTHER POSTINGS, BECAUSE IVE TRIED THEM ALL HERE!!!

In an ideal scenario, you shouldn't be doing that. Various devices would have different colors, as they decide. If you really really have to customize the menu item's backgrounds, then, I would suggest don't use it. Instead, create some kind of context menu, which you can fully customize as per your needs.
在理想情况下，您不应该这样做。根据他们的决定，不同的设备会有不同的颜色。如果您真的必须自定义菜单项的背景，那么我建议不要使用它。相反，创建某种上下文菜单，您可以根据需要对其进行完全自定义。
I know its probably not a solution you are asking for, but whatever workarounds you will be be doing for this, it might work for a few device, and would probably be a disaster for others.
我知道这可能不是您要求的解决方案，但是无论您为此采取什么解决方法，它都可能适用于一些设备，而对其他人来说可能是一场灾难。

i was searching for the same stuff but when i installed my application in my Samsung galaxy Ywhich is having version 2.3.6. i got black background for optionmenu automatically.although the emulator displays me white background for same menu.i don't know how it is working like that,but i got what i want.so i left it unaltered.
Here is the code:
我正在寻找相同的东西，但是当我在我的三星 Galaxy Y 中安装了我的应用程序时，它的版本是 2.3.6。我自动获得了 optionmenu 的黑色背景。虽然模拟器为我显示了同一个菜单的白色背景。我不知道它是如何工作的，但我得到了我想要的。所以我没有改变它。
这是代码：
@Override
public boolean onCreateOptionsMenu(Menu menu) {
super.onCreateOptionsMenu(menu);
MenuInflater inflater1 = getMenuInflater();
inflater1.inflate(R.menu.scfmenu, menu);
return true;
}
@Override
public boolean onOptionsItemSelected(MenuItem item) {
switch (item.getItemId()) {
case R.id.settings:
Intent i = new Intent(getApplicationContext(), prefsActivity.class);
startActivity(i);
break;
case R.id.logout:
Intent j = new Intent(getApplicationContext(), LoginActivity.class);
startActivity(j);
break;
}
return super.onOptionsItemSelected(item);
}

I found this funny postfrom codeproject. You can custom everything you want: bk color, icon. And you can change the menu style with this:
我从 codeproject 中发现了这篇有趣的帖子。您可以自定义您想要的一切：bk 颜色、图标。您可以通过以下方式更改菜单样式：
mMenu.setItemsPerLineInLandscapeOrientation(8);
mMenu.setItemsPerLineInPortraitOrientation(4);
Note: it is a trick to add view look like option menu. Hope this help!
注意：添加视图看起来像选项菜单是一个技巧。希望这有帮助！

i have used the code as shown below on 2.3.1 version and it works and just call in onCreat method addOptionsMenuHackerInflaterFactory();
我在 2.3.1 版本上使用了如下所示的代码，它可以工作，只需调用 onCreat 方法 addOptionsMenuHackerInflaterFactory();
private static final int COLOR_MENU_ID = Menu.FIRST;
private static final int EMBOSS_MENU_ID = Menu.FIRST + 1;
private static final int BLUR_MENU_ID = Menu.FIRST + 2;
@Override
public boolean onCreateOptionsMenu(Menu menu) {
super.onCreateOptionsMenu(menu);
menu.add(0, COLOR_MENU_ID, 0, "Color").setShortcut('3', 'c');
menu.add(0, EMBOSS_MENU_ID, 0, "Emboss").setShortcut('4', 's');
menu.add(0, BLUR_MENU_ID, 0, "Blur").setShortcut('5', 'z');
return true;
}
@Override
public boolean onPrepareOptionsMenu(Menu menu) {
super.onPrepareOptionsMenu(menu);
return true;
}
@Override

return super.onOptionsItemSelected(item);
