專案中需要在一個Listview不僅有OnItemClicked還需要item中某一個按鈕具有單獨的點選事件。在安卓官網中 已經有了類似的實現

程式碼主要是在ListView的apdater中的getView中

/**
 * A simple array adapter that creates a list of cheeses.
 */
class PopupAdapter extends ArrayAdapter<String> {

    PopupAdapter(ArrayList<String> items) {
        super
 
(getActivity(), R.layout.list_item, android.R.id.text1, items);
    }

    @Override
public View getView(int position, View convertView, ViewGroup container) {
        // Let ArrayAdapter inflate the layout and set the text
View view = super.getView(position, convertView, container);

        // BEGIN_INCLUDE(button_popup)
 
        // Retrieve the popup button from the inflated view
View popupButton = view.findViewById(R.id.button_popup);

        // Set the item as the button's tag so it can be retrieved later
popupButton.setTag(getItem(position));

        // Set the fragment instance as the OnClickListener
popupButton.setOnClickListener(PopupListFragment.this
 
);
        // END_INCLUDE(button_popup)
        // Finally return the view to be displayed
return view;
    }
}

@Override
public void onClick(final View view) {
    // We need to post a Runnable to show the popup to make sure that the PopupMenu is
    // correctly positioned. The reason being that the view may change position before the
    // PopupMenu is shown.
view.post(new Runnable() {
        @Override
public void run() {
            showPopupMenu(view);
        }
    });
}

// BEGIN_INCLUDE(show_popup)
private void showPopupMenu(View view) {
    final PopupAdapter adapter = (PopupAdapter) getListAdapter();

    // Retrieve the clicked item from view's tag
final String item = (String) view.getTag();

    // Create a PopupMenu, giving it the clicked view for an anchor
PopupMenu popup = new PopupMenu(getActivity(), view);

    // Inflate our menu resource into the PopupMenu's Menu
popup.getMenuInflater().inflate(R.menu.popup, popup.getMenu());

    // Set a listener so we are notified if a menu item is clicked
popup.setOnMenuItemClickListener(new PopupMenu.OnMenuItemClickListener() {
        @Override
public boolean onMenuItemClick(MenuItem menuItem) {
            switch (menuItem.getItemId()) {
                case R.id.menu_remove:
                    // Remove the item from the adapter
adapter.remove(item);
                    return true;
            }
            return false;
        }
    });

    // Finally show the PopupMenu
popup.show();
}
// END_INCLUDE(show_popup)
