Intent intent = new Intent(LoginActivity.this,RegisterActivity.class);
startActivityForResult(intent, 201);//请求码
从登录页跳转到注册页
注册页finish之前把数值传回来
Intent intent=new Intent();
intent.putExtra(“userName”, userName);
intent.putExtra(“passWord”, passWord);
setResult(202);//resultcode
//登录界面对返回结果的处理
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
// TODO Auto-generated method stub
super.onActivityResult(requestCode, resultCode, data);
if(requestCode==201&&resultCode==202){
String userName=data.getStringExtra(“userName”);
