Question

如果我使用示例A ，溢出菜单的背景为白色，正如预期的那样。但如果我使用样本B ，则背景为黑色。我需要样品B因为我想要显示图标。但我需要保持背景白色。我该怎么做？

示例A

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

样本B

findViewById(R.id.moreMenuBtn).setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(final View v) {
                PopupMenu popupMenu = new PopupMenu(v.getContext(), v);
                popupMenu.inflate(R.menu.menu_dogs);
                forceShowIcon(popupMenu);
                popupMenu.show();
}
public static void forceShowIcon(PopupMenu popup) {
        try {
            Field[] fields = popup.getClass().getDeclaredFields();
            for (Field field : fields) {
                if ("mPopup".equals(field.getName())) {
                    field.setAccessible(true);
                    Object menuPopupHelper = field.get(popup);
                    Class<?> classPopupHelper = Class.forName(menuPopupHelper
                            .getClass().getName());
                    Method setForceIcons = classPopupHelper.getMethod(
                            "setForceShowIcon", boolean.class);
                    setForceIcons.invoke(menuPopupHelper, true);
                    break;
                }
            }
        } catch (Exception e) {
            e.printStackTrace();
        }
    }

应用主题

<style name="AppTheme" parent="Theme.AppCompat.Light.NoActionBar">
    <!-- Customize your theme here. -->
    <item name="colorPrimary">@color/colorPrimary</item>
    <item name="colorPrimaryDark">@color/colorPrimaryDark</item>
    <item name="colorAccent">@color/colorAccent</item>
</style>

Answer 1

试试这个：

<style name="AppTheme" parent="Theme.AppCompat.Light.NoActionBar">
    <!-- Customize your theme here. -->
    <item name="colorPrimary">@color/colorPrimary</item>
    <item name="colorPrimaryDark">@color/colorPrimaryDark</item>
    <item name="colorAccent">@color/colorAccent</item>
    <item name="android:popupMenuStyle">@style/PopupMenu</item>
</style>
<style name="PopupMenu" parent="AppTheme">
    <item name="android:popupBackground">@color/colorPrimary</item>
    <item name="android:textColor">@color/colorAccent</item>
</style>

Answer 2

将popupMenu样式添加到 AppTheme ：

<style name="AppTheme" parent="android:Theme.Light.NoActionBar">
    <item name="android:popupMenuStyle">@style/PopupMenu</item>
</style>

<style name="PopupMenu" parent="@android:style/Widget.PopupMenu">
    <item name="android:popupBackground">@android:color/white</item>
</style>

<强>的manifest.xml：

 <application
    android:allowBackup="true"
    android:icon="@drawable/ic_launcher"
    android:label="@string/app_name"
    android:theme="@style/AppTheme" >
.............
</application>
