要实现点击上面listview中每一行中的请假就会获得该行的人名来调用相应的webservice接口，
departmenttongji_item：
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical"

<LinearLayout

Listview中的adapter：
public class KqtjAdapter extends BaseAdapter{
ArrayList<PersonKqStatisInfo> list;
Context mcontext;
public KqtjAdapter(ArrayList<PersonKqStatisInfo> list, Context mcontext) {
this.list = list;
this.mcontext = mcontext;
}
@Override
public int getCount() {
return list.size();
}
@Override
public Object getItem(int position) {
return list.get(position);
}
@Override
public long getItemId(int position) {
return position;
}
@Override
public View getView( int position, View convertView, ViewGroup parent) {
ViewHolder viewHolder;
if (convertView==null) {
convertView = LayoutInflater.from(mcontext).inflate(R.layout.departmenttongji_item, null);
viewHolder=new ViewHolder();
viewHolder.holiday=(TextView)convertView.findViewById(R.id.holiday);
viewHolder.name=(TextView)convertView.findViewById(R.id.name);
viewHolder.work=(TextView)convertView.findViewById(R.id.work);
viewHolder.nowork=(TextView)convertView.findViewById(R.id.nowork);
viewHolder.outwork=(TextView)convertView.findViewById(R.id.outwork);
viewHolder.dayofkq=(TextView)convertView.findViewById(R.id.dayofkq);
convertView.setTag(viewHolder);
}
else {
viewHolder=(ViewHolder)convertView.getTag();
}
viewHolder.name.setText(list.get(position).getName());
viewHolder.work.setText(list.get(position).getWork()+"");
viewHolder.nowork.setText(list.get(position).getNowork()+"");
viewHolder.outwork.setText(list.get(position).getOutwrok()+"");
viewHolder.holiday.setText(list.get(position).getHoliday()+"");
viewHolder.holiday.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
Log.i("tag","position:"+ position+"");
}
});
return convertView;
}
class ViewHolder{
TextView name,
work,
nowork,
outwork,
dayofkq,
holiday;
}
}
上面是该listview的adapter，如果直接在adapter中调用点击事件时发现Log.i(“tag”,”position:”+ position+”“)输出的position的值并不是所得到的点击的当前行的值，所以并不能通过这种方法来获取点击请假的时候获取当前行的人名。
这时候就这时候就要理解
public void onItemClick(AdapterView parent, View view, int position,long id) {
}
中的参数的意思，其中view是当前点击行所在的view，position是当前行的位置其值和id相同。
因此就可以在该方法中实现获取当前点击请假所在的行的人名：
listView.setOnItemClickListener(new AdapterView.OnItemClickListener() {
@Override
public void onItemClick(AdapterView<?> parent, View view, int position,long id) {
final TextView name=(TextView)view.findViewById(R.id.name);
view.findViewById(R.id.work).setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
Log.i("tag"," P: "+name.getText().toString());
}
});
}
});
上面的view也就是当前所点击的行的view，可以通过该view来找到里面的每个元素。
