android - returning id of a listview item by clicking on a button -



want custom listview in android studio each item has button. clicking on button should return id of item in listview button in main activity.
had added layout xmls , problem in mainactivity.java , class needed in it.

in adapter's getview method set button's tag e.g.:-

    public view getview(int position, view convertview, viewgroup parent) {           button yourbutton = (button) view.findviewbyid(r.id.yourbuttonid);         yourbutton.settag(position);         .......

in button's onclick handling use int position = (int) view.gettag(); retrieve position should correlate array's index.

there 2 main ways of handling button's onclick in listview

1) specify method used in button's xml (only since api level 4) , provide handling method in invoking activity:-

example xml :-

<button android:id="@+id/mybutton"     android:layout_width="wrap_content"     android:layout_height="wrap_content"     android:text="click"     android:onclick="mybuttonclicked" />

example handler in activity includes respective listview

    .....     public mybuttonclicked(view view) {         int position = (int) view.gettag();         ....     }

2) include setting listener , onclick handling in listview's adapter's getview method.

example :-

        public view getview(int position, view convertview, viewgroup parent) {               button yourbutton = (button) view.findviewbyid(r.id.yourbuttonid);             yourbutton.settag(position);             yourbutton.setonclicklistener(new onclicklistener() {                public void onclick(view view) {                    int position = view.gettag();                }             });

you may wish have @ these, cover above in more detail

i find xml method convenient. utilise style basis buttons (i use textview buttons) have single method (as set in style) incorporate respective activities. copes admirably multiple buttons per listview item.
