我在ListView上使用图像按钮,单击时会显示一个弹出菜单。 但问题是物品不可见。 这就是菜单的样子。我可以在这张图片的菜单上看到白色文字,但在移动屏幕上它是不可见的。
这是styles.xml
<resources>

这是我要显示的菜单。

这是Quiz Fragment的布局文件。

</LinearLayout>
我尝试了之前提出的许多解决方案(都是关于工具栏菜单),但没有一个对我有用。 我在styles.xml中定义了一个新样式
<style name="itemTextStyle.AppTheme" parent="@android:style/TextAppearance.Widget.IconMenu.Item">
<item name="android:textColor">@android:color/black</item>
<item name="android:colorBackground">@color/colorPrimary</item>
并将其包含在没有工作的AppTheme中。然后我将其包含在工具栏样式,菜单布局,QuizFragment布局中,但项目仍然不可见。如何更改菜单的背景颜色或项目颜色来修复此问题,任何人都会工作。

试试这个
style.xml
function parseDMY(s) {
var b = s.split(/\D/);
var d = new Date(b[2], --b[1], b[0]);
// If month is wrong, return invalid date
return d && d.getMonth() == b[1]? d : new Date(NaN);
}
// Dates in d/m/y format
['23/10/2015','32/10/2015','12/13/2015'].forEach(function(s){
var d = parseDMY(s);
console.log(s + ' : ' + (isNaN(d)? 'Invalid' : 'Valid'));
});
并在<style name="CustomActionBarTheme" parent="@style/Theme.AppCompat">
<item name="android:actionOverflowButtonStyle">@style/OverflowButton</item>
<item name="actionOverflowButtonStyle">@style/OverflowButton</item>
<item name="windowNoTitle">true</item>

Activity
的主题
AndroidManifest.xml

我只使用两个主题文件(黑暗和白天)
Theme.MaterialComponents.DayNight.NoActionBar.Bridge
在它们里面,我只有白天和黑夜的同名物品,但颜色不同。发现(经过实验)...在我的情况下(与您的问题相同),此行改变了游戏规则,标题和菜单为白色,同时弹出菜单上的文本为黑色
<item name="android:textColorSecondary">@android:color/white</item>
这是整个文件,我只使用了这个,并且尽量不硬编码任何东西。
<resources xmlns:tools="http://schemas.android.com/tools">
<!-- Base application theme. -->
<style name="Theme.Ch+++itche+++++" parent="Theme.MaterialComponents.DayNight.NoActionBar.Bridge">
<!-- Primary brand color. -->
<item name="android:textColorSecondary">@android:color/white</item>
<item name="colorPrimary">@color/primaryColor</item>
<item name="colorPrimaryVariant">@color/primaryDarkColor</item>
<item name="colorOnPrimary">@color/primaryLightColor</item>
<item name="colorOnSurface">@color/primaryColorWhiteDay</item>
<item name="android:statusBarColor" tools:targetApi="l">?attr/colorPrimaryVariant</item>
<!-- Customize your theme here. -->
</style>
仅此而已,
快乐编码, 内纳德
