2.5.3 Spinner(列表选项框)的基本使用

etContentView(R.layout.activity_main); mContext = MainActivity.this; mData = new ArrayList<Hero>(); bindViews(); } private void bindViews() { spin_one = (Spinner) findViewById(R.id.spin_one); spin_two = (Spinner) findViewById(R.id.spin_two); mData.add(new Hero(R.mipmap.iv_lol_icon1,"迅捷斥候：提莫（Teemo）")); mData.add(new Hero(R.mipmap.iv_lol_icon2,"诺克萨斯之手：德莱厄斯（Darius）")); mData.add(new Hero(R.mipmap.iv_lol_icon3,"无极剑圣：易（Yi）")); mData.add(new Hero(R.mipmap.iv_lol_icon4,"德莱厄斯：德莱文（Draven）")); mData.add(new Hero(R.mipmap.iv_lol_icon5,"德邦总管：赵信（XinZhao）")); mData.add(new Hero(R.mipmap.iv_lol_icon6,"狂战士：奥拉夫（Olaf）")); myAdadpter = new MyAdapter<Hero>(mData,R.layout.item_spin_hero) { @Override public void bindView(ViewHolder holder, Hero obj) { holder.setImageResource(R.id.img_icon,obj.gethIcon()); holder.setText(R.id.txt_name, obj.gethName()); } }; spin_two.setAdapter(myAdadpter); spin_one.setOnItemSelectedListener(this); spin_two.setOnItemSelectedListener(this); } @Override public void onItemSelected(AdapterView<?> parent, View view, int position, long id) { switch (parent.getId()){ case R.id.spin_one: if(one_selected){ Toast.makeText(mContext,"您的分段是~：" + parent.getItemAtPosition(position).toString(), Toast.LENGTH_SHORT).show(); }else one_selected = true; break; case R.id.spin_two: if(two_selected){ TextView txt_name = (TextView) view.findViewById(R.id.txt_name); Toast.makeText(mContext,"您选择的英雄是~：" + txt_name.getText().toString(), Toast.LENGTH_SHORT).show(); }else two_selected = true; break; } } @Override public void onNothingSelected(AdapterView<?> parent) { }}另外关于Spinner的OnItemSelectedListener，以及如何获得选中项的值，就自己看上面的代码啦~3.代码示例下载：SpinnerDemo.zip本节小结好的，本节给大家介绍了Spinner(下拉选项框)的使用，例子还是蛮有趣的，哈哈~！别问我哪个区什么段位，我可是人机小王子，可惜一直在青铜分段苦苦挣扎~你知道为什么的，好吧，本节就到这里~
