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！！！

看看以下解决方案是否能解决您的问题......

AndroidMenifest.xml

<application android:icon="@drawable/ic_launcher" android:label="@string/app_name" android:theme="@style/CustomTheme">

菜单/选项.xml

<menu xmlns:android="http://schemas.android.com/apk/res/android">
    <item android:id="@+id/option_1" android:title="Android"/>
    <item android:id="@+id/option_2" android:title="iPhone"/>
    <item android:id="@+id/option_3" android:title="iPad"/>
</menu>

样式.xml

<resources>
    <style name="CustomTheme" parent="android:Theme">
        <!-- Panel attributes -->
        <!-- <item name="android:panelBackground">@drawable/menu_bg</item> -->
        <item name="android:panelFullBackground">@drawable/menu_full_bg</item> 
            <!--    <item name="android:panelColorBackground">#FF0000</item> -->
    </style>

    <!-- <drawable name="menu_bg">#DDDAAA</drawable> -->
    <drawable name="menu_full_bg">#000FFF</drawable>

</resources>

StackoverflowActivity.java 

public class StackoverflowActivity extends Activity {

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);
    }

    @Override
    public boolean onCreateOptionsMenu(Menu menu) {
        getMenuInflater().inflate(R.menu.options, menu);
        return true;
    }

}

下面的代码工作正常 2.3.6（在设备和模拟器上测试）。它几乎是从谷歌搜索的不同网站复制和组合的

@Override
public boolean onCreateOptionsMenu(Menu menu) {
    MenuInflater inflater = getMenuInflater();
    inflater.inflate(R.menu.menu, menu);
    setMenuBackground();
    return super.onCreateOptionsMenu(menu);
}

protected void setMenuBackground() {
    getLayoutInflater().setFactory(new Factory() {
     @Override
                public View onCreateView(final String name, final Context context,
                        final AttributeSet attrs) {

                    if (name.equalsIgnoreCase("com.android.internal.view.menu.IconMenuItemView")) {

                        try { // Ask our inflater to create the view
                            final LayoutInflater f = getLayoutInflater();
                            final View[] view = new View[1];
                            try {

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);
}
@SuppressWarnings("rawtypes")

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！
