问题 What I have: I have a Xamarin.Forms app with a ToolBar ( ActionBar on Android, Navigation Bar on iOS). Within the ToolBar I have a ToolBarItem to delete something. What I want: For the ToolBarItem mentioned above I want to use the native platform icons (f.e. a trash can). My question: What is the proper way to achieve this?

问题 I'm making an Android app using tabs for navigation. I have a problem with the rendering of the last tab in the action bar; it goes off screen and is cropped (this happens as soon as the number of tabs is too big too fit in the screeen width as far as I can tell).

I haven't been able to find any questions with the same problem, any ideas on how to prevent this behavior? 回答1: I have already answer a question like that one : Tab item

问题 I would hide navigation bar and action bar of my app after some second that display don't get touched, and expand current view to fullscreen. Then if user touch the screen (or better if he swipe down), make visible both again. How to? 回答1: You can use a Handler to delay certain actions. Handler h = new Handler(); h.postDelayed(new Runnable() { @Override public void run() { // DO DELAYED STUFF getActionBar().hide(); } }, delaytime); // e.g. 3000 milliseconds The actions you take inside the run

问题 By following this guide, http://wptrafficanalyzer.in/blog/adding-drop-down-navigation-to-action-bar-in-android/ I was able to add my drop down navigation bar. The click events and everything function. Now, how do I make it so once an option is selected, it navigates to a different screen with its own layout and different functions.

问题 I'm using the new ActionBarCompat support library. The action buttons in the actionbar should change their background when pressed, It works with Android 4.3 but not with Gingerbread. In Gingerbread if I press on a button it will not change the background.
