如何检测对 ActionBar 标题的点击? [英] How can I detect a click on the ActionBar title?

问题描述

对于特定的客户要求，我需要允许我的应用的用户(不会在 Market 中发布)点击 ActionBar 标题来执行一些操作.

For specific customer requirement, I need to allow the user of my app ( won't be published in Market) to click on the ActionBar title to execute some actions.

我一直在寻找 Android 源代码，但找不到 actionBar TextView 标题的 ID.

I have been looking in the Android source, but I am not able to find an ID for the actionBar TextView title.

是否有适当的方法来处理此类点击?

Is there a proper way to handle such clicks?

推荐答案

标题是不可点击的AFAIK.图标/徽标是可点击的——您可以通过 onOptionsItemSelected() 中的 android.R.id.home 获得它.可以想象，标题也是如此，尽管他们没有提及，我也不会依赖它.

The title is non-clickable AFAIK. The icon/logo is clickable -- you'll get that via android.R.id.home in onOptionsItemSelected(). Conceivably, the title also routes this way, though they don't mention it and I wouldn't rely upon it.

听起来您想要一个 Spinner 供用户选择要执行的操作.如果是这样，请使用 setListNavigationCallbacks().如果您想删除现在多余的标题，请使用 setDisplayOptions(0, DISPLAY_SHOW_TITLE).

It sounds like you want a Spinner for the user to choose the actions to execute. If so, use setListNavigationCallbacks(). If you want to remove the title as now being superfluous, use setDisplayOptions(0, DISPLAY_SHOW_TITLE).

如果您想要操作栏左侧的 Spinner 以外的其他内容，请使用 setDisplayOptions(DISPLAY_SHOW_CUSTOM, DISPLAY_SHOW_CUSTOM) 和 setCustomView().请注意，不建议使用这种方法("避免在操作栏")，因为它可能不适用于手机，尤其是在纵向模式下.

If you want something other than a Spinner on the left side of the action bar, use setDisplayOptions(DISPLAY_SHOW_CUSTOM, DISPLAY_SHOW_CUSTOM) and setCustomView(). Note that this approach is not recommended ("Avoid using custom navigation modes in the action bar"), as it may not work well with phones, particularly in portrait mode.

另一种可能性是删除标题并使用徽标代替图标，并在徽标中将您的标题"作为图像的一部分.整个徽标应该是可点击的，通过 onOptionsItemSelected() 拾取.

Another possibility would be to remove the title and use a logo instead of the icon, and in the logo have your "title" as part of the image. The whole logo should be clickable, picked up via onOptionsItemSelected().
