Android 判断下拉菜单spinner选择了哪个选项

相信大家平时开发的时候都遇到过一些小问题，找了很多资料还是解决不了，大神们也没遇到过，下拉菜单，对话框这些项目都比较常见的，今天我们来看看spinner的用法，很简单的一个控件，我平时习惯调用spinner的ArrayAdapter，把你的菜单中的选项都放在String类型的集合里，在绑定到ArrayAdapter里，spinner的监听事件OnItemSelecedListener

判断选项调用方法getSelecedItem和String集合里的字符串比较，大致思路就是这些,下面直接上代码：

private String [] list1 = {"换人计划","换人名单","面试名单"};
private String [] list2 = {"全部","香港PB","万邦MSI","香港华林"};
private String [] list3 = {"全部","Albany Sound","Puget Sound","Tasman Sound"};
private ArrayAdapter arrayAdapter1;
private ArrayAdapter arrayAdapter2;
private ArrayAdapter arrayAdapter3;

arrayAdapter1 = new ArrayAdapter(this, R.layout.spinner_checked_text, list1);
change_list.setAdapter(arrayAdapter1);
arrayAdapter2 = new ArrayAdapter(this, R.layout.spinner_checked_text, list2);
flotilla.setAdapter(arrayAdapter2);
arrayAdapter3 = new ArrayAdapter(this, R.layout.spinner_checked_text, list3);
ships_name.setAdapter(arrayAdapter3);
changePlanAdapter = new ChangePlanAdapter(this, ship_name, date, place, names);
changeListAdapter = new ChangeListAdapter(this, post, change_plan, downship_person, upship_person);
interViewListAdapter = new InterViewListAdapter(this, post_name, mode, choice_of_persons, time_of_appointment);
change_list.setOnItemSelectedListener(new AdapterView.OnItemSelectedListener() {
    @Override
    public void onItemSelected(AdapterView parent, View view, int position, long id) {
        if (change_list.getSelectedItem().toString().equals("换人计划")) {
            listView.setAdapter(changePlanAdapter);
            listView.setOnItemClickListener(new AdapterView.OnItemClickListener() {
                @Override
                public void onItemClick(AdapterView parent, View view, int position, long id) {
                    Intent intent = new Intent(ChangeManagementActivity.this, SubstitutionPlanActivity.class);
                    startActivity(intent);
                }
            });
        } else if (change_list.getSelectedItem().toString().equals("换人名单")) {
            interview_list_layout.setVisibility(View.GONE);
            change_list_layout.setVisibility(View.VISIBLE);
            listView.setAdapter(changeListAdapter);
        } else if (change_list.getSelectedItem().toString().equals("面试名单")) {
            change_list_layout.setVisibility(View.GONE);
            interview_list_layout.setVisibility(View.VISIBLE);
            listView.setAdapter(interViewListAdapter);
        }
    }

    @Override
    public void onNothingSelected(AdapterView parent) {
    }
});
