ListView配合popmenu的使用

  项目中需要在一个Listview不仅有OnItemClicked还需要item中某一个按钮具有单独的点击事件。在安卓官网中 已经有了类似的实现

官网地址https://developer.android.com/samples/ActionBarCompat-ListPopupMenu/index.html

代码主要是在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;    }}

而后是点击事件的代码

@Overridepublic 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)

这样就实现了一个listview的一个条目不同点击事件
