动作条微调用一个图标（如谷歌地图），我怎么能做到这一点？ [英] ActionBar spinner with an icon (like Google Maps), how can I achieve that?

问题描述

我目前想，除了惊人的ActionBerSherlock库中添加一个微调导航菜单在我的应用程序（如谷歌地图）

I am currently trying, in addition of the amazing ActionBerSherlock library to add a spinner navigation menu in my application (like Google Maps)

注：我一直还想着Spotify的/ Evernote的/ Facebook的模式，但在Android上似乎不妥：的 http://alexanderblom.se/2012/04/23/android-navigation-and-spotify/

Note: I have been thinking also about the SPotify/Evernote/Facebook pattern, but that seems inappropriate on Android: http://alexanderblom.se/2012/04/23/android-navigation-and-spotify/

我已经制作了微调（http://developer.android.com/design/building-blocks/spinners.html），但添加一个图标看起来不那么容易。

I have already worked on the spinner (http://developer.android.com/design/building-blocks/spinners.html), but adding an icon seems not so easy

感谢了很多此菜...

Thank a lot for any link or help on this menu...

推荐答案

首先，你需要创建一个CustomArrayAdapter为您的微调。它应同时处理，字符串数组和可绘制的数组。在你的情况可能是第二个阵列的一小总结。

First you need to create a CustomArrayAdapter for your spinner. It should handle both, an array of Strings and an array of Drawables. In your case perhaps a second array for a little summary.

那么你就需要为项目的布局与ImageView的的图标和一个TextView文本（也许是一个用于汇总）。重写getView（）和getDropDownView（），以填补递了资源布局（createFromResource（）可能是一个方法来考虑）。

Then you'll need a layout for the item with the ImageView for the icon and a TextView for the text (and perhaps one for the summary). Override the getView() and the getDropDownView() to fill your layout with the resources handed in (createFromResource() might be a method to look into).

有关导航，所有你需要做的是建立在你的onCreate）的CustomArrayAdapter（与资源的阵列，调用MyActionBar.setNavigationMode（ActionBar.NAVIGATION_MODE_LIST），并通过MyActionBar.setListNavigationCallbacks饲料导航与您的CustomArrayAdapter（名单，这一点）。

For the Navigation, all you need to do is to create the CustomArrayAdapter in your onCreate() with the arrays of resources, call MyActionBar.setNavigationMode(ActionBar.NAVIGATION_MODE_LIST) and feed the Navigation with your CustomArrayAdapter via MyActionBar.setListNavigationCallbacks(list, this).
