我为spinner编写了一个setOnItemSelectedListener,以便在更改微调器项时进行响应.我的要求是当我再次点击当前选择的项目时,应显示一个Toast.如何举办此活动？再次单击当前选定的项目时,微调器没有响应.`

    StorageSpinner.setOnItemSelectedListener(new AdapterView.OnItemSelectedListener(){

        @Override
        public void onItemSelected(AdapterView adapter, View v, int i, long lng) {              
            Toast.makeText(getApplicationContext(), (CharSequence) StorageSpinner.getSelectedItem(), Toast.LENGTH_SHORT).show();

        }

        @Override
        public void onNothingSelected(AdapterView arg0) {
            Toast.makeText(getApplicationContext(), "Nothing selected", Toast.LENGTH_SHORT).show();

        }
    });
