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到这一点的帖子，但这些帖子不适用于 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机？
**注意* * 没有图像放置！！！没有其他帖子的代码，因为我在这里都试过了！！！

在理想情况下，您不应该这样做。根据他们的决定，各种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。
我知道它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，并且可能对其他人来说是一场灾难。

我正在寻找相同的东西，但是当我将我的应用程序安装在版本为 2.3.6的三星 Galaxy Y中时。我自动获得了选项菜单的黑色背景。虽然模拟器为我显示相同菜单的白色背景。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);
}

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
public boolean onOptionsItemSelected(MenuItem item) {
return super.onOptionsItemSelected(item);
}

我从 codeproject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。您可以使用以下方法更改菜单样式：
mMenu.setItemsPerLineInLandscapeOrientation(8);
mMenu.setItemsPerLineInPortraitOrientation(4);
注意：添加类似于选项菜单的视图是一个技巧。希望这有帮助！
