Android Long Press Spinner View

问题

I want to be able to long press items in the spinner view and have a contextMenu appear. I tried this code:

spinner = (Spinner) findViewById(R.id.catagorySpinner);
ArrayAdapter<String> adapter = new ArrayAdapter<String>(context,android.R.layout.simple_dropdown_item_1line, data);
spinner.setAdapter(adapter);
registerForContextMenu(spinner);

but as you can guess this added a context menu to the actual Spinner and not to the contents inside. Does anyone know how i can do this?

回答1:

Have you tried this?

        spinner.setOnItemLongClickListener(new OnItemLongClickListener() {

            public boolean onItemLongClick(AdapterView<?> parent, View view, int arg2, long arg3) {

                view.showContextMenu();
                return true;

            }
        });

You can register for each item inside the adapter's getView() method.

View getView(View convertView, ... ) {
   ....
   // inflate view or reuse.
   ....
   getContext().registerForContextMenu(convertView);
   ....
   return convertView;
}
