I don't understand why the attributes are not being found, considering I added

问题 I want to change the background color of the overflow popup menu to match the background of the main screen. Does anyone know how I could do that? Thanks. 回答1: If you are using a Toolbar, first you need to add this line to your toolbar layout: app:popupTheme="@style/ThemeOverlay.MyTheme" It should look like this: <android.support.v7.widget.Toolbar xmlns:android="http://schemas.android.com/apk/res/android" xmlns:app="http://schemas.android.com/apk/res-auto" android:id="@+id/toolbar" android

问题 I would like to maximize use of the screen for a Honeycomb app. Since the bottom of the screen is already stuck with "always-on" items, I'd like to add a menu button down there in that space rather than sacrificing more screen space putting an "action bar" across the top. How can I accomplish this without downgrading to API 10 or less? (As much as I don't need an action bar using up more space, I also don't need a resize button that does my app no good at all and can't be disabled except by

问题 There is a situation in which I want to use Tab bar as well as List navigation, Both at same time in Action bar. Documentation says 'we can put Actionbar in to list navigation mode or tabs navigation mode'. Is there any way to use both at same time. Any pointers, help. Thank you in Advance. 回答1: Sorry, you can only have one or the other.

问题 I was following official developer's guide to overlay actionbar. my style.xml is as following: <!-- Base application theme. --> <style name="AppBaseTheme" parent="Theme.AppCompat.Light.DarkActionBar"> <!-- Customize your theme here. --> </style> <style name="AppTheme" parent="AppBaseTheme"> <item name="actionBarStyle">@style/CustomActionBarTheme</item> </style> <style name="CustomActionBarTheme" parent="@android:style/Theme.Holo"> <item name="android:windowActionBarOverlay">true</item> <

问题 Have researched this to death and just cannot find the answer. I have an ActionBar using AppCompat. I am supporting up to API v7 (API v8 would do). ActionBar works perfectly from API v11. API < v11 has the problem of removing an icon (and thus a feature) from the ActionBar without supplying an Overflow. The big picture is that I have an App Logo, an App Title, and 3 Icons all squidging into the same ActionBar on a low end phone. Trying to make some room! I would be happy with 1 of 2 solutions

问题 After using Actionbar i thought that what if same widget could be available for native android platform. I dont know if we can grab the styles and apply it to native widgets from actionbar apis(compatibility library v4) or not. What i am asking is spinner widget like below which is mostly used in actionbar. Check for dropdown widget. Is it possible to use the same in native like in Listview ? Many thanks. 回答1: adapter = new ArrayAdapter<CharSequence>(this,android.R.layout.simple_spinner_item,

问题 Currently I'm developing an Android application and we are using the action bar with a spinner navigation for a specific view. The main problem is: The user should be able to reselect an action bar spinner item, after he already selected this item. Android seems to prevent a second selection of an action bar spinner item. Is there a way to be able to select an item more than once or is there a completely other way to achieve this behavior? 回答1: Ok, now after many attempts I found a working
