我现在构建一个电子邮件应用程序android，所以我想将电子邮件保存到设备，有人告诉eml文件并序列化你自己的类！任何人都可以指导我真正的方向请帮助我！如何使用onScrollListner()方法快速加载所有邮箱，因为现在它很慢
我使用asynctask来加载它！这是我的代码：
private class CheckMailInboxTask extends AsyncTask<Integer, Void, Message[]>{
private int count;
private ProgressDialog progressDialog;
private Message[] messages;
private boolean statusMail = true;
@Override
protected void onPreExecute() {
super.onPreExecute();
progressDialog = new ProgressDialog(this);
progressDialog.setTitle("Loading mail");
progressDialog.setMessage("Please wait...");
progressDialog.show();
}
@Override
protected Message[] doInBackground(Integer... params) {
try {
messages = AccueilActivity.emailManager.getMails();
EmailManager.inbox.addMessageCountListener(new MessageCountAdapter() {
@Override
public void messagesAdded(MessageCountEvent e) {
super.messagesAdded(e);
System.out.println("New Message");
try {
Message[] messages = e.getMessages();
int count = messages.length;
for(int i=(count - 1);i >= 0;i--){
final MimeMessage msg = (MimeMessage) messages[i];
Mail email = null;
try {
email = new Mail(msg);
email.set_box(true);
Mail.INBOX.add(0,email);
Mail.LISTBOOL.add(Boolean.valueOf(true));//Nampiako
if(BoiteReceptionActivity.handler != null){
BoiteReceptionActivity.handler.sendEmptyMessage(1);
ab.setSubtitle("1 mail non lu(s)");
}
} catch (IOException ex) {
ex.printStackTrace();
}
}
} catch (MessagingException emx) {
}
}
});
new Thread(new Runnable() {
@Override
public void run() {
System.out.println("UUUUUUUUUUUUUUUUUUUUU");
if (EmailManager.inbox instanceof IMAPFolder) {
final IMAPFolder imapFolder = (IMAPFolder)EmailManager.inbox;
startListening(imapFolder);
}
System.out.println("DDDDDDDDDDDDDDDDDDDDD");
}
}).start();
count = messages.length;
for(int i=(count - 1);i >= 0;i--){
MimeMessage msg = (MimeMessage) messages[i];
Mail email = null;
try {
if(msg.isSet(Flags.Flag.SEEN)){
email = new Mail(msg);
email.set_box(true);
Mail.INBOX.add(email);
Mail.LISTBOOL.add(Boolean.valueOf(false));
Log.d("SIZE OF MAIL_INBOX SEEN", ""+Mail.INBOX.size());
Log.d("SIZE OF BOOL SEEN", ""+Mail.LISTBOOL.get(0));
}else {
email = new Mail(msg);
email.set_box(true);
Mail.INBOX.add(email);
Mail.LISTBOOL.add(Boolean.valueOf(true));
Log.d("SIZE OF MAIL_INBOX RECENT", ""+Mail.INBOX.size());
Log.d("SIZE OF BOOL RECENT", ""+Mail.LISTBOOL.size());
}
AccueilActivity.emailManager.setInboxList(Mail.INBOX);
new Thread(new Runnable() {
@Override
public void run() {
BoiteReceptionActivity.this.runOnUiThread(new Runnable() {
@Override
public void run() {
//Mail.COUNT_MESSAGES = Mail.INBOX.size();
Mail.in_adapteur.notifyDataSetChanged();
progressDialog.dismiss();
}
});
}
}).start();
} catch (IOException e) {
e.printStackTrace();
}
}
} catch (MessagingException e) {
}
return messages;
}
@Override
protected void onPostExecute(Message[] messages) {
super.onPostExecute(messages);
}
}
修改 这是我的客户适配器
public class AdapterBoiteReception extends BaseAdapter{
private Context context;
private List<Mail> listMail;
private List<Boolean> listBool;
public AdapterBoiteReception(Context ctx, List<Mail> list, List<Boolean> listBool){
this.context = ctx;
this.listMail = list;
this.listBool = listBool;
}
@Override
public int getCount() {
// TODO Auto-generated method stub
return listMail.size();
}
@Override
public Object getItem(int position) {
// TODO Auto-generated method stub
return listMail.get(position);
}
@Override
public long getItemId(int position) {
// TODO Auto-generated method stub
return listMail.indexOf(getItem(position));
}
@Override
public View getView(int position, View convertView, ViewGroup parent) {
// TODO Auto-generated method stub
View view =convertView;
Holder mailHolder = null;
LayoutInflater mInflater = (LayoutInflater) context
.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
if(view == null){
view = mInflater.inflate(R.layout.boite_reception_items, null);
mailHolder = new Holder();
mailHolder.nomTV = (TextView) view.findViewById(R.id.nomMsgTV);
mailHolder.objetTV = (TextView) view.findViewById(R.id.objectMsgTV);
mailHolder.dateTV = (TextView) view.findViewById(R.id.dateMsgTV);
mailHolder.img = (ImageButton) view.findViewById(R.id.imgBtnAttache);
view.setTag(mailHolder);
}else
mailHolder = (Holder) view.getTag();
Mail mail = listMail.get(position);
Log.d("VALUE OF LISTBOOL", ""+Boolean.valueOf(listBool.get(position)));
if(Boolean.valueOf(listBool.get(position)).equals(Boolean.TRUE)){
mailHolder.nomTV.setTypeface(null, Typeface.BOLD);
mailHolder.objetTV.setTypeface(null, Typeface.BOLD);
mailHolder.dateTV.setTypeface(null, Typeface.BOLD);
mailHolder.nomTV.setText(mail.getNom());
mailHolder.objetTV.setText(mail.getSubject());
try {
mailHolder.dateTV.setText(mail.getDate());
} catch (MessagingException e) {
e.printStackTrace();
}
if(mail.getHandlers().size() > 0)
mailHolder.img.setVisibility(View.VISIBLE);
else
mailHolder.img.setVisibility(View.INVISIBLE);
}else{
view.setBackgroundColor(Color.GRAY);
mailHolder.nomTV.setText(mail.getNom());
mailHolder.objetTV.setText(mail.getSubject());
try {
mailHolder.dateTV.setText(mail.getDate());
} catch (MessagingException e) {
e.printStackTrace();
}
if(mail.getHandlers().size() > 0)
mailHolder.img.setVisibility(View.VISIBLE);
else
mailHolder.img.setVisibility(View.INVISIBLE);
}
return view;
}
static class Holder{
TextView nomTV;
TextView objetTV;
TextView dateTV;
ImageButton img;
}
}
修改
