options-menu

问题 I'm following a book on Android Development to get myself started writing my first real app. I got up to the point where I'm making an options menu for one of my activities. The menu shows up, but the corresponding icon of the menu item refuses to display. Here is the code for the menu: ReminderListActivity @Override public boolean onCreateOptionsMenu(Menu menu) { super.onCreateOptionsMenu(menu); MenuInflater mi = getMenuInflater(); mi.inflate(R.menu.list_menu, menu); return true; } res/menu

问题 I am trying to create options menu in my Android program. I am using the following code to inflate options menu : @Override public boolean onCreateOptionsMenu(Menu menu) { super.onCreateOptionsMenu(menu); MenuInflater inflater=getMenuInflater(); inflater.inflate(R.menu.optionsmenu, menu); return true; } And my xml code is : ?xml version="1.0" encoding="utf-8"?> <menu xmlns:android="http://schemas.android.com/apk/res/android"> <item android:id="@+id/Option1" android:title="Option1"/> <item

问题 The app runs fine. On devices with hard options menu button the menu shows up, so i know it works. On some devices it shows the overflow button at the top-right. I my test case the device is Asus Zenphone 5 there is no hard button, i dont get a overflow button either. But when i run the showOptionsMenu() command from a button click it displays the options menu and all related events work no issues. Menu - Xml <?xml version="1.0" encoding="utf-8"?> <menu xmlns:android="http://schemas.android

问题 When the user clicks on the Menu button I present a few menu items. One of them is a Sign Out button. I want to be able to change the text between "Sign In" and "Sign Out" depending on a boolean value I am tracking. How can I programmatically change the text in the menu? 回答1: You want to override the onPrepareOptionsMenu function in the Activity. There is a menu parameter passed, you can simply find the menuitem that you want to show/hide (or change the image and text) and return true.

问题 I am receiving an inflation error when pressing the Menu button and adding a menu item in the onCreateOptionsMenu method. I've included some of the error below. The code is as follows, and works if I try it on its own and not as part of my activity as a whole. I don't think it's feasible to paste in the whole of my activity here (I have no idea which bit could be causing this), so am wondering if anyone has experienced this before? public boolean onCreateOptionsMenu(Menu m) { Log.d(TAG, "Menu
