Tooltip in Items within RecyclerView (Overlap above items)

问题

I need to create a RecyclerView with multiple ViewTypes. However, on some of the items, I need to display a Tooltip which should hover over the above row.

My requirement is:

In the above image, there are 4 items in the RecyclerView, and the tooltip in the lower row should overlap on top of the above row (or rows, as required). This tooltip would only be visible in some scenarios - when the lock icon is visible.

The problem is, if I add this tooltip as a TextView to the row_layout.xml, and control it's visibility programmatically, it increases the height of that row and does not overlap onto the above layout.

How can I get this view to "hover" over the above rows without displacing them?

If you require code, I can edit this question and post the code too (but I think it might not be necessary here).

回答1:

You can make use of Android Tooltips library.

Simple to use customizable Android Tooltips library based on PopupWindow. This Tooltips does not require any custom layout. It works as PopupWindow.

dependencies {
    compile 'com.github.vihtarb:tooltip:0.1.9'
}

usage:

Tooltip tooltip = new Tooltip.Builder(anchorView)
    .setText("Hello tooltip")
    .show();
