问题 I'm developing one application in which I have to add a custom layout on actionbar. Adding the custom layout is done, but when I'm adding the menu items on actionbar my custom layout changes it's position from right of the actionbar to center of the actionbar.

问题 Every time I need to create a menu or toolbar with actions I end up collecting some images extracted from different application and hand tuning them with the image editor. This is time consuming and boring (eventhough I admit that might be a refreshing break in some ocasions). Do you know of any collection of such images? I would like to have at least images for all the menu items in the menu templates. They must be copyright-free. Thanks. 回答1: There are the silk icons (and others from

问题 I've built a splash screen that loads a (splash) activity and then starts another activity and it works fine. (I've attached it below - it's called SPLASH 1) I created another splash screen to replace this one which is supposed to only run once - then after creating a SharedPreferences boolean it is supposed to load another activity.

问题 The MenuItem control has the convenient property IsEnabled (inherited from UIElement). This allows me to, when appropriate, hide the command exposed by that menu option. But if that command is also bound to a key (e.g. Ctrl+K), the user can still access it. How do I get the IsEnabled functionality to a KeyBinding? 回答1: If you bind the KeyBinding to an ICommand , you can just set the ICommand.CanExecute to false (and potentially raise CanExecuteChanged). This will "disable" the KeyBinding

问题 In my action bar, I have defined a menu item that can show text "DONE" by the code below: Menu.xml: <menu xmlns:android="http://schemas.android.com/apk/res/android" > <item android:id="@+id/action_register_text" android:actionLayout="@layout/action_done_text" android:title="@string/action_done" android:showAsAction="always"/> </menu> action_done_text.xml: <?xml version="1.0" encoding="utf-8"?> <FrameLayout xmlns:android="http://schemas.android.com/apk/res/android" android:id="@+id/expand
