using method inside asyntask in android

using method inside asyntask in android

i have created one simple login application which takes user name and
password from sqlserver..it works fine...
i want during login process one progeress bar should be displayed using
asyntask... but i am unaware to use parameters in asyntask...if some one
plzz tell me how to put my method in doInbackground of asyntask and what
param should i use....
my code is;.....
public void save(){
initilize();
ResultSet rs = null;
String mylog=id.getText().toString();
String mypass=pass.getText().toString();
try{
Statement statement=connect.createStatement();
rs=statement.executeQuery("LOGIN '"+mylog+"', '"+mypass+"'");
}catch(Exception e){
e.printStackTrace();
}
if(mylog.equals("")||mypass.equals("")){
Toast.makeText(getApplicationContext(), "empty fields",
Toast.LENGTH_SHORT).show();
} else
try {
if(rs.next()){
Intent i=new Intent(getApplicationContext(),Act2.class);
startActivity(i);
}
else if(rs.next()==false){
Toast.makeText(getApplicationContext(), "incorrect login",
Toast.LENGTH_SHORT).show();
id.setText("");
pass.setText("");
}
} catch (SQLException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
if it is possible that same method save() be kept inside doInbackground()
of asyntask...
