如何更改Android 2.3的"选项"菜单背景？

Question

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.

有没有人知道一个工作菜单inflater与自定义颜色背景兼容版本2.3？

**注意** 没有图像放置!其他帖子没有代码,因为我在这里试过了!

看看以下解决方案是否解决了您的问题....

AndroidMenifest.xml

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

菜单/ options.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>

styles.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).它几乎从谷歌搜索的不同网站复制和组合

@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 {
                                view[0] = f.createView(name, null, attrs);
                            } catch (InflateException e) {
                                hackAndroid23(name, attrs, f, view);
                            }
                            // Kind of apply our own background
                            new Handler().post(new Runnable() {
                                public void run() {
                                    view[0].setBackgroundColor(Color.BLUE);

                                }
                            });
                            return view[0];
                        } catch (InflateException e) {

                        }

Answer 3

在理想的情况下,你不应该这样做.根据他们的决定,各种设备会有不同的颜色.如果你真的必须自定义菜单项的背景,那么,我建议不要使用它.而是创建某种上下文菜单,您可以根据需要进行完全自定义.

我知道它可能不是你要求的解决方案,但无论你为此做些什么工作,它可能适用于一些设备,并且可能对其他人来说是一场灾难.
