Question

将Object从一个活动传递到另一个活动时遇到问题。我正在使用Jsch（）类，因为我想进行Sftp连接。

这在我的登录活动中：

ServerConnect lLogin = new ServerConnect(lUser,lPass,lIP,lPort);
ASYNCLogin lASYNC = new ASYNCLogin(lLogin,getBaseContext());
lASYNC.execute();

我的ASYNC任务：

    @Override
    protected Integer doInBackground(Void... params)
    {
        if(mServerConnect.connectServer())
            return 1;       
        return 0;       
    }
    @Override
    protected void onPostExecute(Integer result)
    {       
        //Toast.makeText(mContext, "Sucessfully Connected!", Toast.LENGTH_LONG).show();         
        Intent lListFiles = new Intent(mContext,ListFilesActivity.class);       
        lListFiles.putExtra("ServerConnect", mServerConnect);
        lListFiles.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
        mContext.startActivity(lListFiles);
    }

我的ServerConnect类中的connect方法：

public boolean connectServer()
    {
        try
        {
            mSession=mSsh.getSession(mUsername,mServerIP,mServerPort);
            mSession.setConfig(mConfig);
            mSession.setPassword(mPassword);
            mSession.connect();         
            mChannel = mSession.openChannel("sftp");
            mChannel.connect();
        }
}

我如何在其他活动中获取对象：

mLogin = (ServerConnect) getIntent().getSerializableExtra("ServerConnect");

我尝试使用Serializable，但它不起作用，因为我无法在java.lang.Object类中实现Serializable接口.... 我也尝试使用Parcelable，但我不知道如何将自定义类写入Parcable。是否有其他方法可以将Object从Login Activity传递给另一个？

logcat的：
