How to obtain the focus of edittext in listview

How to obtain the focus of multiple edittexts in listview?

// Get the focus after listview, with a priority lower than item

Listview. setdescendantfocusability (listview. focus_after_descendants );

My idea is to listen to the button click event on the package layer button in the edittext header to get the focus
