Question

我正在尝试在任何Gmail帐户中阅读电子邮件。以下是代码，如何列出任何已使用getMail（）方法的Gmail帐户中的收件箱项目。

mailReader.java



package myMail.namespace;

import java.security.Security;
import javax.mail.Folder;
import javax.mail.Message;
import javax.mail.MessagingException;
import javax.mail.Session;
import javax.mail.Store;

public class mailReader extends javax.mail.Authenticator{

    static {
        Security.addProvider(new myMail.namespace.JSSEProvider());
    }

    static Session session;
    static Store store;

    public static Message [] getMail() throws MessagingException{
        connect();
        Folder folder = store.getFolder("Inbox");
        folder.open(Folder.READ_ONLY);
        Message[] messages = folder.getMessages();
        return messages;
        }

    private static void connect() throws MessagingException{
        if (null != session)
            return;
            java.util.Properties props = new java.util.Properties();
            props.setProperty("mail.imap.socketFactory.class",
            "javax.net.ssl.SSLSocketFactory");
            props.setProperty("mail.imap.socketFactory.fallback", "false");
            props.setProperty("mail.imap.socketFactory.port", "993");
            session = Session.getDefaultInstance(props);
            store = session.getStore("imap");
            store.connect("imap.gmail.com", "myMail@gmail.com", "myPass");
    }
}

package myMail.namespace; import java.security.Security; import javax.mail.Folder; import javax.mail.Message; import javax.mail.MessagingException; import javax.mail.Session; import javax.mail.Store; public class mailReader extends javax.mail.Authenticator{ static { Security.addProvider(new myMail.namespace.JSSEProvider()); } static Session session; static Store store; public static Message [] getMail() throws MessagingException{ connect(); Folder folder = store.getFolder("Inbox"); folder.open(Folder.READ_ONLY); Message[] messages = folder.getMessages(); return messages; } private static void connect() throws MessagingException{ if (null != session) return; java.util.Properties props = new java.util.Properties(); props.setProperty("mail.imap.socketFactory.class", "javax.net.ssl.SSLSocketFactory"); props.setProperty("mail.imap.socketFactory.fallback", "false"); props.setProperty("mail.imap.socketFactory.port", "993"); session = Session.getDefaultInstance(props); store = session.getStore("imap"); store.connect("imap.gmail.com", "myMail@gmail.com", "myPass"); } }

和readMail类

package myMail.namespace;

import javax.mail.Message;
import javax.mail.MessagingException;

import android.app.ListActivity;
import android.os.Bundle;
import android.util.Log;
import android.view.View;
import android.view.ViewGroup;
import android.widget.ArrayAdapter;
import android.widget.TextView;

public class readMail extends ListActivity{

    /** Called when the activity is first created. */
    @Override
    public void onCreate(Bundle icicle) {
    super.onCreate(icicle);
    //setContentView(R.layout.main);
    Message[] messages = new Message[] { };

    try {
        messages = mailReader.getMail();
    } 
    catch (MessagingException e) {
        Log.e("mailReader getMail error. in readmail.java", e.getMessage(), e);
    }

    setListAdapter(new ArrayAdapter<Message>(this,
    android.R.layout.simple_list_item_1, messages){
        @Override
        public View getView(int position, View convertView, ViewGroup parent) {
            Message message = getItem(position);
            TextView resultView = null;
            resultView = new TextView(super.getContext());
            try {
                resultView.setText(message.getSubject());
            } 
            catch (MessagingException e) {
                Log.e("resultView.setText in readmail", e.getMessage(), e);
            }
            return resultView;
        }
    });
    }
}

和JSSE提供商

package myMail.namespace; import javax.mail.Message; import javax.mail.MessagingException; import android.app.ListActivity; import android.os.Bundle; import android.util.Log; import android.view.View; import android.view.ViewGroup; import android.widget.ArrayAdapter; import android.widget.TextView; public class readMail extends ListActivity{ /** Called when the activity is first created. */ @Override public void onCreate(Bundle icicle) { super.onCreate(icicle); //setContentView(R.layout.main); Message[] messages = new Message[] { }; try { messages = mailReader.getMail(); } catch (MessagingException e) { Log.e("mailReader getMail error. in readmail.java", e.getMessage(), e); } setListAdapter(new ArrayAdapter<Message>(this, android.R.layout.simple_list_item_1, messages){ @Override public View getView(int position, View convertView, ViewGroup parent) { Message message = getItem(position); TextView resultView = null; resultView = new TextView(super.getContext()); try { resultView.setText(message.getSubject()); } catch (MessagingException e) { Log.e("resultView.setText in readmail", e.getMessage(), e); } return resultView; } }); } }

Answer 1

我认为你应该在“public View getView（int position，View convertView，ViewGroup parent）”的函数中调用super.getView（）来获取有效的布局视图并从中查找文本视图，然后填写电子邮件的主题。
