推荐答案

Android仅支持从Android 4.0开始的ActionBar按钮使用工具提示".但是正如Jaguar已经提到的那样，Android中的工具提示没有太大意义，因为没有悬停的概念.

Android supports "tool-tip" only for ActionBar buttons from Android 4.0 on. But as Jaguar already mentioned, tool-tips in Android doesnt make so much sense, since there is no concept of hovering.

在Android 4.0中，如果长按按钮，则会显示普通标题文本(您在xml文件中设置或通过代码设置).但是，如果屏幕上有足够的空间，它将始终在ActionBar中的图标旁边可见.

From Android 4.0 the normal title text (that you set in the xml file or via code) will appear if you make a long click on the button. But if enough space is on the screen, it will be visible in the ActionBar all the time beside the icon.

如果您希望将其用于自定义视图，则需要自己添加一个 LongClickListener 转到您的视图，并显示 Toast :

If you want to have it for a custom view, you need to implement it yourself by adding a LongClickListener to your view, and show a Toast when pressed long:

view.setOnLongClickListener(new OnLongClickListener() {
    public boolean onLongClick(View v) {
        Toast.makeText(v.getContext(), "My tool-tip text", Toast.LENGTH_SHORT).show();
        return true;
    }
}

当然，您应该为字符串使用资源，而不是硬编码字符串.

Of course you should use a resource for the string, and not the hard coded string.
