我试图改变弹出菜单的背景,但我实现不起作用。
这是我的代码:
<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>
应用在AndroidManifest.xml
<application
android:hardwareAccelerated="true"
android:label="@string/app_name"
android:icon="@drawable/ic_launcher"
android:theme="@style/MyHoloLight">
Answer 1:
以下样式为我工作完美。
<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>
在这里,父母应该是AppTheme父
并且在代码中使用这些行。
Context wrapper = new ContextThemeWrapper(context, R.style.popupMenuStyle);
PopupMenu popup = new PopupMenu(wrapper, v);
我希望它会奏效。
Answer 2:
如果bgPopumMenu是你的图像,然后用这个。
<style name="popupMenuStyle" parent="@android:style/Widget.PopupMenu">
<item name="android:popupBackground">@drawable/bgPopumMenu</item>
</style>
你需要你的风格应用到您的AppTheme。 因此,尝试这一点。
<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>
Answer 3:
我做了@ Raju`s代码和一些变化工作对我来说以下样式,
Context wrapper = new ContextThemeWrapper(context,R.style.popupMenuStyle);
PopupMenu popup = new PopupMenu(wrapper, YourView);
这就是我的风格,
<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>
Answer 4:
如果您使用的自定义主题:
在清单: @style/MyMaterialTheme
是我的自定义主题:
<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
在Java类弹出式菜单:
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);
- 这是popup-菜单的自定义样式为自己绘制背景
<style name="popupMenuStyle" parent="@android:style/Widget.PopupMenu"> <item name="android:popupBackground">@drawable/dropdown_bg</item> </style>
然后在自己的主题更改“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>
Answer 5:
我解决了它,
PopupMenu popup = new PopupMenu(context, view);
在上面的代码中使用的我的类型上下文Activity
不是Context
类型。
冷静!
Answer 6:
那这个呢 :
@Override
public boolean onCreateOptionsMenu(Menu menu)
{
MenuInflater inflater=getMenuInflater();
inflater.inflate(R.menu.menu,menu);
setMenuBackground();
return true;
}
而在写这setMenuBackground()
方法
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;
}});
}
Answer 7:
你不能给android:popupBackground
只是一个颜色。 您应该使用或创建一个drawable
。
你可以使用这个链接http://jgilfelt.github.io/android-actionbarstylegenerator/来生成所需的颜色。 并且其设置为drawable
。
Answer 8:
尝试定义android:actionBarWidgetTheme
在你的主题:
<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>
Answer 9:
如果bgPopumMenu是您的绘制,然后使用这个
<item name="android:panelBackground">@drawable/bgPopumMenu</item>
你只要把直接进入你的AppTheme像这样
<style name="AppTheme" parent="android:Theme.Holo.Light">
<item name="android:panelBackground">@drawable/bgPopumMenu</item>
</style>
Answer 10:
您可以轻松地创建弹出菜单风格和样式应用到一个主题,你可以为主题分配到活动/父活动***在这样的Android清单
<style name="MyThemePopup" parent="@style/AppTheme.NoActionBar">
<item name="android:popupMenuStyle">@style/PopupMenu</item>
</style>
创建@风格/ PopupMenu的这样
<style name="PopupMenu" parent="@android:style/Widget.PopupMenu">
<item name="android:popupBackground">#000000</item>
</style>
分配MyThemePopup主题,以您的活动/父活动***在AndroidManifest作为
<activity
android:name=".Activity"
android:label="@string/title_activity"
android:screenOrientation="portrait"
android:theme="@style/MyThemePopup"/>
***当使用片段应用的主题为AndroidManifest定义父活动
Answer 11:
只需添加下面一行到Style.xml及其工作:
<style name="AppTheme" parent="Theme.AppCompat.Light.NoActionBar">
<!-- To change action bar menuItem BG -->
<item name="android:itemBackground">@color/white</item>
</style>
