问题
I tried to change background of popupmenu, but my implementation does not work.
This is my code:
<style name="MyHoloLight" 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>
Apply in AndroidManifest.xml
<application
android:hardwareAccelerated="true"
android:label="@string/app_name"
android:icon="@drawable/ic_launcher"
android:theme="@style/MyHoloLight">
回答1:
the following styles working perfectly for me.
<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 AppTheme parent
and in your code use these lines.
Context wrapper = new ContextThemeWrapper(context, R.style.popupMenuStyle);
PopupMenu popup = new PopupMenu(wrapper, v);
i hope it will work.

If bgPopumMenu is your image then use this.
<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.
<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 made some changes of @Raju`s code and the following styles working for me,
Context wrapper = new ContextThemeWrapper(context,R.style.popupMenuStyle);
PopupMenu popup = new PopupMenu(wrapper, YourView);
and this is my style,
<style name="popupMenuStyle" parent="android:Theme.Holo.Light.DarkActionBar">
<item name="android:popupMenuStyle">@style/MyApp.PopupMenu</item>
<item name="android:textColor">@color/White</item>
</style>
<style name="MyApp.PopupMenu" parent="android:Widget.Holo.Light.ListPopupWindow">
<item name="android:popupBackground">@color/color_semi_transparent</item>
</style>

If you are using custom theme :
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 :
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
<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>

I SOLVED it,
PopupMenu popup = new PopupMenu(context, view);
In above code I used context of type Activity not of Context type.
Chill !
回答6:
what about this :
@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
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:popupBackground as just a color. You should use or create a drawable.
You can use this link http://jgilfelt.github.io/android-actionbarstylegenerator/ to generate your desired color. And set it to that drawable.
回答8:
Try to define android:actionBarWidgetTheme in your theme:
<style name="MyHoloLight" parent="android:Theme.Holo.Light">
<item name="android:popupMenuStyle">@style/popupMenuStyle</item>
<item name="android:actionBarWidgetTheme">@style/Theme.Example.Widget</item>
</style>
<style name="popupMenuStyle" parent="@android:style/Widget.PopupMenu">
<item name="android:popupBackground">@color/bgPopumMenu</item>
</style>
<style name="Theme.Example.Widget" parent="@style/Theme.AppCompat">
<item name="popupMenuStyle">@style/popupMenuStyle</item>
<item name="dropDownListViewStyle">@style/DropDownListView.Example</item>
</style>
<style name="DropDownListView.Example" parent="@style/Widget.AppCompat.ListView.DropDown">
<item name="android:listSelector">@color/bgPopumMenu_whenSelected</item>
</style>
回答9:
If bgPopumMenu is your drawable then use this
<item name="android:panelBackground">@drawable/bgPopumMenu</item>
You just put that directly into your AppTheme like so
<style name="AppTheme" parent="android:Theme.Holo.Light">
<item name="android:panelBackground">@drawable/bgPopumMenu</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
<style name="MyThemePopup" parent="@style/AppTheme.NoActionBar">
<item name="android:popupMenuStyle">@style/PopupMenu</item>
</style>
Create @style/PopupMenu like this
<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
<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
回答11:
just add below line into Style.xml and its working :
<style name="AppTheme" parent="Theme.AppCompat.Light.NoActionBar">
<!-- To change action bar menuItem BG -->
<item name="android:itemBackground">@color/white</item>
</style>
