the following styles working perfectly for me.
以下样式非常适合我。
<style name="popupMenuStyle" parent="Theme.AppCompat.Light.DarkActionBar">
<item name="android:textColor">@color/color_white</item>
<item name="android:itemBackground">@color/color_red</item>
</style>
here, parent should be the AppThemeparent
在这里， parent 应该是AppTheme 的父级
and in your code use these lines.
并在您的代码中使用这些行。
Context wrapper = new ContextThemeWrapper(context, R.style.popupMenuStyle);
PopupMenu popup = new PopupMenu(wrapper, v);
i hope it will work.
我希望它会起作用。

If bgPopumMenuis your image then use this.
如果bgPopumMenu是您的图像，则使用它。
<style name="popupMenuStyle" parent="@android:style/Widget.PopupMenu">
<item name="android:popupBackground">@drawable/bgPopumMenu</item>
</style>
You need to apply your style to your AppTheme. So try this.
您需要将您的风格应用到您的 AppTheme。所以试试这个。
<style name="AppTheme" parent="android:Theme.Holo.Light">
<item name="android:popupMenuStyle">@style/popupMenuStyle</item>
</style>
<style name="popupMenuStyle" parent="@android:style/Widget.PopupMenu">
<item name="android:popupBackground">@color/bgPopumMenu</item>
</style>

I SOLVED it,
我解决了，
PopupMenu popup = new PopupMenu(context, view);
PopupMenu popup = new PopupMenu(context, view);
In above code I used context of type Activitynot of Contexttype.
在上面的代码中，我使用了类型Activity不是Context类型的上下文。
Chill !
寒意 ！

If you are using custom theme :
如果您使用自定义主题：
In Manifest :
@style/MyMaterialThemeis my customized theme :<application android:allowBackup="true" android:icon="@mipmap/ic_launcher" android:label="@string/app_name" android:supportsRtl="true" android:theme="@style/MyMaterialTheme">Use this code :
R.style.popupMenuStylefor popup menu in java class :
在 Manifest 中：
@style/MyMaterialTheme是我定制的主题：<application android:allowBackup="true" android:icon="@mipmap/ic_launcher" android:label="@string/app_name" android:supportsRtl="true" android:theme="@style/MyMaterialTheme">使用此代码：
R.style.popupMenuStyle用于 java 类中的弹出菜单：
Context wrapper = new ContextThemeWrapper(getContext(), R.style.popupMenuStyle);
PopupMenu popup = new PopupMenu(wrapper, v);
//Inflating the Popup using xml file
popup.getMenuInflater().inflate(R.menu.popup_menu, popup.getMenu());
MenuPopupHelper menuHelper = new MenuPopupHelper(wrapper, (MenuBuilder) popup.getMenu(), v);
menuHelper.setForceShowIcon(true);
menuHelper.setGravity(Gravity.RIGHT);
- this is custom style of popup- menu for your own background drawable
- 这是您自己的可绘制背景的自定义弹出菜单样式
<style name="popupMenuStyle" parent="@android:style/Widget.PopupMenu">
<item name="android:popupBackground">@drawable/dropdown_bg</item>
</style>
then change in your own theme "popupMenuStyle"
<style name="MyMaterialTheme" parent="MyMaterialTheme.Base"> </style> <style name="MyMaterialTheme.Base" parent="Theme.AppCompat.Light.DarkActionBar"> <item name="windowNoTitle">true</item> <item name="windowActionBar">false</item> <item name="colorPrimary">@color/colorPrimary</item> <item name="colorPrimaryDark">@color/colorPrimaryDark</item> <item name="colorAccent">@color/colorPrimary</item> <item name="popupMenuStyle">@style/popupMenuStyle</item> <item name="android:popupMenuStyle">@style/popupMenuStyle</item> </style>
然后更改您自己的主题“popupMenuStyle”
<style name="MyMaterialTheme" parent="MyMaterialTheme.Base"> </style> <style name="MyMaterialTheme.Base" parent="Theme.AppCompat.Light.DarkActionBar"> <item name="windowNoTitle">true</item> <item name="windowActionBar">false</item> <item name="colorPrimary">@color/colorPrimary</item> <item name="colorPrimaryDark">@color/colorPrimaryDark</item> <item name="colorAccent">@color/colorPrimary</item> <item name="popupMenuStyle">@style/popupMenuStyle</item> <item name="android:popupMenuStyle">@style/popupMenuStyle</item> </style>

You can easily create a style for popup menu and apply that style to a theme and you can assign the theme to the Activity/Parent Activity*** in the android manifest like this
您可以轻松地为弹出菜单创建样式并将该样式应用于主题，您可以像这样将主题分配给 android manifest 中的 Activity/Parent Activity***
<style name="MyThemePopup" parent="@style/AppTheme.NoActionBar">
<item name="android:popupMenuStyle">@style/PopupMenu</item>
</style>
Create @style/PopupMenu like this
像这样创建@style/PopupMenu
<style name="PopupMenu" parent="@android:style/Widget.PopupMenu">
<item name="android:popupBackground">#000000</item>
</style>
Assign the MyThemePopup theme to your Activity/Parent Activity*** in AndroidManifest as
在 AndroidManifest 中将 MyThemePopup 主题分配给您的活动/父活动***
<activity
android:name=".Activity"
android:label="@string/title_activity"
android:screenOrientation="portrait"
android:theme="@style/MyThemePopup"/>
***When you using the fragment apply the theme for the parent activity defined in AndroidManifest
***当您使用片段时，请为 AndroidManifest 中定义的父活动应用主题

<!-- To change action bar menuItem BG -->
<item name="android:itemBackground">@color/white</item>
</style>
回答by Lucian Novac
what about this :
那这个呢 ：
@Override
public boolean onCreateOptionsMenu(Menu menu)
{
MenuInflater inflater=getMenuInflater();
inflater.inflate(R.menu.menu,menu);
setMenuBackground();
return true;
}
and write this in the setMenuBackground()method
并在setMenuBackground()方法中 写下这个
protected void setMenuBackground(){
getLayoutInflater().setFactory( new Factory() {
public View onCreateView(String name, Context context, AttributeSet attrs) {
if ( name.equalsIgnoreCase( "com.android.internal.view.menu.IconMenuItemView" ) ) {
try { // Ask our inflater to create the view
LayoutInflater f = getLayoutInflater();
final View view = f.createView( name, null, attrs );
/* The background gets refreshed each time a new item is added the options menu.
* So each time Android applies the default background we need to set our own
* background. This is done using a thread giving the background change as runnable
* object */
new Handler().post( new Runnable() {
public void run () {
// sets the background here
view.setBackgroundResource( R.drawable.bgPopumMenu);
// sets the text color
((TextView) view).setTextColor(Color.BLACK);
// sets the text size
((TextView) view).setTextSize(18);
}
} );
return view;
}
catch ( InflateException e ) {}
catch ( ClassNotFoundException e ) {}
}
return null;
}});
}

You cannot give android:popupBackgroundas just a color. You should use or create a drawable.
你不能仅仅给出android:popupBackground一种颜色。您应该使用或创建一个drawable.
You can use this link http://jgilfelt.github.io/android-actionbarstylegenerator/to generate your desired color. And set it to that drawable.
您可以使用此链接http://jgilfelt.github.io/android-actionbarstylegenerator/生成您想要的颜色。并将其设置为drawable.

尝试android:actionBarWidgetTheme在您的主题中定义：
