我正在以编程方式制作复选框。并且我想在点击按钮时获得已检查复选框的价值...我该怎么做....
我从数据库中获得了复选框的价值。
这是我的工作代码..
public class Loyaltyprogram extends Activity {
SessionManager session;
EditText mpv, discount;
Button save;
String finalresult, getFlag, statusEmp, accessName, emp_id, bus_id,
preferences, bus_type_id, emp_access_name, responseString, success,
name, id, pref, per_amout, percentage, datediff, dateNo, minpvalue , discountonit;

答案 0 :(得分：0)
只需在循环中执行此操作，否则执行条件
cb.setTag(i+99); // set the tag values so that you can refer to them later.
cb.setOnCheckedChangeListener(handleCheck(cb)); // here pass the checkbox object.
然后这是handleCheck方法
private OnCheckedChangeListener handleCheck (final CheckBox chk)
{
return new OnCheckedChangeListener() {
@Override
public void onCheckedChanged(CompoundButton buttonView, boolean isChecked) {
// TODO Auto-generated method stub
if(!isChecked){
Toast.makeText(getApplicationContext(), "You unchecked " + chk.getTag(),
Toast.LENGTH_LONG).show();
}
else
{
Toast.makeText(getApplicationContext(), "You checked " + chk.getTag(),
Toast.LENGTH_LONG).show();
}
}
};
}
希望这会给你一些想法。快乐的编码：）
