ListView获取Item对应的model注意事项

来源：互联网发布：erp软件测试六部曲编辑：程序博客网时间：2024/05/17 01:44

通常情况下可以根据位置arg2从adpter数据源中获取，

但是如果listView中加上1个head元素之后arg2实际上从1开始了

解决办法1：

把arg2减去1

解决办法2：推荐

FAddress ad  = (FAddress) arg0.getItemAtPosition(arg2)；

或者

OrderTempInfo order = (OrderTempInfo) arg0.getAdapter().getItem(arg2);

//默认可点击的HeaderView
View headView = inflater.inflate(R.layout.search_top, null);
mListView.addHeaderView(headView）
//这样可以让HeaderView不可点击
mListView.addHeaderView(headView ,null,false);

listView.setOnItemClickListener(new AdapterView.OnItemClickListener() {    @Override    public void onItemClick(AdapterView<?> arg0, View arg1, int arg2, long arg3) {     try{         FAddress ad  = (FAddress) arg0.getItemAtPosition(arg2);      //   FAddress ad = (FAddress) mAddressListAdapter.getItem(arg2-1);         Intent intent = new Intent();         intent.putExtra(ExtraName.ADDRESS_ITEM, ad);         if (mComefromOrder) {             View defaultView = mAddressListAdapter.getDefaultView();             if (defaultView != null) {                 defaultView.setBackgroundColor(getApplicationContext().getResources().getColor(android.R.color.transparent));             }             setResult(RESULT_OK, intent);             finish();         }     }catch (Throwable e){         e.printStackTrace();     }    }});
