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); 
} 
}
