公共类CityAdapter扩展了BaseAdapter{
私有上下文;
私人城市;
所选整数_位置=-1;
公共城市适配器(上下文c,ArrayList城市){
mContext=c;
this.city=城市;
}
@凌驾
public int getCount(){
//TODO自动生成的方法存根
返回城市。大小();
}
@凌驾
公共对象getItem(int位置){
//TODO自动生成的方法存根
返回null;
}
@凌驾
公共长getItemId(int位置){
//TODO自动生成的方法存根
返回0;
}
公共视图getView(int位置、视图转换视图、视图组父视图){
观点五;
如果(convertView==null){//如果它没有被回收,初始化一些属性
LayoutInflater充气器=(LayoutInflater)mContext.getSystemService(Context.LAYOUT\u充气器\u服务);
v=充气机。充气(R.layout.raw_city,父项,false);

v=(视图)转换视图;

TextView电视城=(TextView)v.findViewById(R.id.tv城市);
tv_city.setText(city.get(position.getCity());

活动

lv_city.setOnItemClickListener( new AdapterView.OnItemClickListener() {
    @Override
    public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
        Pref.setValue( SelectCity.this, Const.PREF_CITY_ID, cityList.get( position ).getCity_id() );
        finish();//finishing activity
    }
} );
lv_city.setOnItemClickListener(新的AdapterView.OnItemClickListener(){
@凌驾
public void onItemClick(AdapterView父对象、视图、整型位置、长id){
Pref.setValue(选择CITY.this、Const.Pref_CITY_ID、cityList.get(position.getCity_ID());
finish();//正在完成的活动
}
} );

您在listview项中的类错误单击

lv_city.setOnItemClickListener(new OnItemClickListener() {
            @Override
            public void onItemClick(AdapterView<?> parent, View view, int position,
                    long id) {
                Pref.setValue( SelectCity.this, Const.PREF_CITY_ID, 
                cityList.get( position ).getCity_id() );
                finish();//finishing activity
            }
        });
lv_city.setOnItemClickListener(新的OnItemClickListener(){
@凌驾
public void onItemClick(AdapterView父视图、视图、整型位置、,
长id){
Pref.setValue(选择CITY.this、Const.Pref\u CITY\u ID、,
getcitylist.get(position.getCity_id());
finish();//正在完成的活动
}
});

@quick learner's是正确的,但我为您的参考提出了一些想法

  • 如果您使用自定义适配器类,在我的建议中,在自定义适配器类中使用setOnClickListener,这是处理此类情况的更好方法
比如说,

mViewHolder.MyUI.setOnClickListener
