package com.app.mail1;
import android.app.Activity;
import android.os.Bundle;
import android.util.Log;
import android.view.View;
import android.widget.Button;
import android.widget.EditText;

 public class Main extends Activity {

EditText to, from, message, subject; 

@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.main);

    send.setOnClickListener(new View.OnClickListener() {

        public void onClick(View v) {


            try {   
                GMailSender sender = new GMailSender("rockstarjamunjuice@gmail.com", "jamunjuice");
                sender.sendMail("This is Subject",   
                        "This is Body",   
                        "user@gmail.com",   
                        "user@yahoo.com");   
            } catch (Exception e) {

我可以在运行时设置用户名和密码吗？我可以将String设置为可编辑吗？如果我可以编辑此代码并在运行时设置发件人的电子邮件ID和密码，请帮助我吗？

Howto convert String to Editable

如何更改用户名/密码：

将其添加到课程中：

public class Main extends Activity {
    private static String password;
    private static String username;

    public static void setUsername(String user){
        username = user;
    }

    public static void setPassword(String pass){
        password = pass;
    }
    // ...................................
    GMailSender sender = new GMailSender(username, password);

}

然后，您可以更改通行证/名称：

public class SomeClass {
    Main.setUsername("SomeUser");
    Main.setPassword("StrongPassword");
}

Or you can use Intent for transfer data (username/password) in Activity

如何在以下代码中为电子邮件和密码创建运行时条目？
