我知道如何设置的动作条的图标，但我怎么确定哪些图标，目前有？我没有看到像调用getIcon 的访问，我认为这是可以通过ID查找图标视图，因为我已经在动作条做到了这一点与搜索窗口小部件，但我不知道叫什么ID。

I know how to set the icon of the actionbar, but how do I determine what icon is currently there? I don't see an accessor like getIcon , I think it is possible to find the icon view by id, since I've done this with the search widget in the actionbar, but I wouldn't know what id to call.

推荐答案

据 ActionBarView.HomeView 来源$ C ​​$ C，你应该能够得到的ImageView 图标由 android.R.id.home 。

According to the source code of ActionBarView.HomeView you should be able to get ImageView of icon by android.R.id.home.

所以，code可能看起来像：

So code may look like:

ImageView imageView = (ImageView) findViewById(android.R.id.home);
Drawable dr = imageView.getDrawable();

不知道这是否会与支持库

Not sure if this will work with support libraries
