 公共类readInbox扩展ListActivity {/ **当第一次创建活动调用。 * /
@覆盖
公共无效的onCreate(捆绑savedInstanceState){

解决方案

您可以通过 inbox.getMessageCount获取消息的总数(),然后检索最后N号的消息。

 留言信息[] = inbox.getMessages(inbox.getMessageCount() -  25,inbox.getMessageCount());

I'm getting inbox folder of my gmail account, can list the incoming e-mails, but that list is being listed from older mails to newer mails. How can i revert that ?

    public class readInbox extends ListActivity{

/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState){
super.onCreate(savedInstanceState);
//setContentView(R.layout.readmail);

Message[] messages = new Message[] { };

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



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

setListAdapter(adapter);
}
}
解决方案

You can get the total number of messages through inbox.getMessageCount(), then retrieve last N number of messages.

Message messages[] = inbox.getMessages(inbox.getMessageCount() - 25 , inbox.getMessageCount());
