android中spinner如何实现省市二级联动

Androidspinner实现省市二级联动,需要自定义adpter,将数据源绑定到adpter,当点击省时,触发自定义响应事件,改变市,示例如下:

public?class?MainActivity?extends?Activity?{?private?TextView?textView?;?private?Spinner?province;?private?Spinner?city;?????/**?Called?when?the?activity?is?first?created.?*/?????Override?????public?void?onCreate(Bundle?savedInstanceState)?{?????????super.onCreate(savedInstanceState);?????????setContentView(R.layout.main);?????????????????//String{“-省份-“,“河北省“,“山西省“,“北京“};?????????textView?=?(TextView)this.findViewById(R.id.textView);?????????province?=?(Spinner)this.findViewById(R.id.province);?????????city?=?(Spinner)this.findViewById(R.id.city);?????????????????//(处理省的显示)?????????//将可选内容与ArrayAdapter的连接(从资源数组文件中获取数据)?????????ArrayAdapter《CharSequence》?adapter?=??????????????ArrayAdapter.createFromResource(this,?R.array.province,?android.R.layout.simple_spinner_item);??????????//new?ArrayAdapter《String》(this,android.R.layout.simple_spinner_item,?provinces);?????????//设置下拉列表的风格?????????adapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);?????????????????//将数据绑定到Spinner视图上?????????province.setAdapter(adapter);?????????????????//添加条目被选中监听器?????????province.setOnItemSelectedListener(new?AdapterView.OnItemSelectedListener()?{????????????????Override????public?void?onItemSelected(AdapterView《?》?parent,?View?view,int联想智能机(联想g400笔记本)?position,?long?id)?{?????//parent既是province对象?????Spinner?spinner?=?(Spinner)parent;?????String?pro?=??(String)spinner.getItemAtPosition(position);?????//(处理省的市的显示)?????//将默认值与ArrayAdapter连接(从资源数组文件中获取数据)?????ArrayAdapter《CharSequence》?cityAdapter?=?ArrayAdapter.createFromResource????????????????????(MainActivity.this,?R.array.citydefault,?android.R.layout.simple_spinner_item);??????//new??ArrayAdapter《CharSequence》???????????//???????????(MainActivity.this,android.R.layout.simple_spinner_item,?cities);?????//获取所在省含有哪些市(从资源数组文件中获取数据)?????if(pro.equals(“河北省“)){???????????cityAdapter?=?ArrayAdapter.createFromResource?????????????????(MainActivity.this,?R.array.hb,?android.R.layout.simple_spinner_item);?????}else?if(pro.equals(“北京市“)){???????????cityAdapter?=?ArrayAdapter.createFromResource?????????????????(MainActivity.this,?R.array.bj,?android.R.layout.simple_spinner_item);?????}else?if(pro.equals(“山西省“)){???????????cityAdapter?=?ArrayAdapter.createFromResource?????????????????(MainActivity.this,?R.array.shx,?android.R.layout.simple_spinner_item);?????}?????//绑定数据到Spinner(City)上?????city.setAdapter(cityAdapter);????}????Override????public?void?onNothingSelected(AdapterView《?》?parent)?{????????}????????????????});?????}?}
