Android TableLayout数据列表的回显清空实现思路及代码

//数据列表的回显
public void shujulist(){
list<customer> customerlist = dao.findall();
tablelayout tl = (tablelayout) findviewbyid(r.id.tllayout);
log.i(">>>", string.valueof(tl.getchildcount()));
int j = tl.getchildcount();
if(j>1){
/*for(int i=0;i<j;i++){
tl.removeview(tl.getchildat(j-i));//必须从后面减去子元素
}*/
for(int i=j;i>0;i--){
tl.removeview(tl.getchildat(i));//必须从后面减去子元素
}
}
tablerow row = null;
for(customer c : customerlist){
row = new tablerow(this);
//id
textview tvid = new textview(this);
tvid.settext(c.id + "");
row.addview(tvid);
//name
textview tvname = new textview(this);
tvname.settext(c.name);
row.addview(tvname);
//age
textview tvage = new textview(this);
tvage.settext(c.telenumber + "");
row.addview(tvage);
tl.addview(row);
}
}
