How to add a share button to the text selection bar for an EditText?

问题

I notice that when highlighting text in a WebView a share button appears along with the standard copy and select all buttons:

but when highlighting text in a TextView or EditText, there is no such button.

Is there any way to add such a button via XML or can it be done programmatically?

回答1:

You can achieve that by setting a custom selection action mode using

TextView.setCustomSelectionActionModeCallback(ActionMode.Callback)

and so the EditText

Here's a similar question with that was answered with an example

Also visit TextView.html#setCustomSelectionActionModeCallback
