我想创建一个游戏,您必须通过蓝牙将多个设备(4+)连接到主设备(例如平板电脑).将有两个应用程序,一个主要的应用程序,所有数据将从手机发送到手机.这甚至可能吗？

我正在使用不推荐使用的SimpleCursorAdapter来显示从Cursor到ListView的数据.我添加了附加参数0,它删除了代表性的警告,但我想使用更好的方式来显示数据.我已经阅读了一些内容Loader,但不知道如何实现它.什么是下面代码的更好的替代品？如何将此代码转换为使用Loader？

Cursor c = mDbHelper.getAllRecords();
    startManagingCursor(c); //this is also deprecated

    String[] from = new String[] { "Name" };
    int[] to = new int[] { R.id.text1 };

    SimpleCursorAdapter names =
        new SimpleCursorAdapter(this, R.layout.names_row, c, from, to, 0);
    setListAdapter(names);

我正在Windows上的Eclipse中使用Egit，以尝试从私有Git克隆存储库。它可以连接，但是在下载时出现“ Packfile被截断”错误。我的网络浏览器和文件浏览器都关闭了。有谁知道是什么问题？

如何在Windows操作系统中的仿真器上更改电池电量(从50%到70%并且不充电)？有一些指南,但所有指南都是针对Ubuntu的.

我正在尝试使用游标在ListView中显示预填充数据库(超过100000行)中的所有项目.它可以工作,但应用程序启动并显示ListView需要几分钟的时间.有更快的方法吗？我读过有关FTS3表的内容,会有帮助吗？

我正在使用ArrayList<HashMap<String, String>>SimpleAdapter和自定义2行布局.码:

Cursor cursor = sDictionary.query("FTSgesla", new String[] {PodatkovnaBaza.KEY_WORD, PodatkovnaBaza.KEY_DEFINITION}, null, null, null, null, PodatkovnaBaza.KEY_WORD);

    if (cursor == null) 
    {

            // There are no results
            mTextView.setText("Empty");
    } 
    else 
    {

        HashMap<String, String> item;

        if(cursor.moveToFirst())
        {
            do
            {
                item = new HashMap<String, String>();
                item.put("line1", cursor.getString(0));
                item.put("line2", cursor.getString(1));
                list.add(item);
            }
            while(cursor.moveToNext());
        }

            sa = new SimpleAdapter(GlavniActivity.this, list,
                    R.layout.result,
                    new String[] { "line1","line2" },
                    new int[] {R.id.word, R.id.definition});

            mListView.setAdapter(sa);
            // Define the on-click listener for the list items
            mListView.setOnItemClickListener(new OnItemClickListener() { …

我正在使用ActionBarSherlock,然后onOptionsItemSelected在单击特定菜单项时启动新活动.代码在添加ABS之前正常工作,现在我收到了case expressions must be constant expressions错误case.

@Override
    public boolean onOptionsItemSelected(com.actionbarsherlock.view.MenuItem item) 
    {
        switch (item.getItemId()) {
        case R.id.about: //error
            startActivity(new Intent(this, AboutActivity.class));
            break;
        case R.id.feedback: //error
            //launch activity
            break;

        default:
            break;
        return super.onOptionsItemSelected(item);
    }

在添加ActionBarSherlock之前,相同的代码工作正常.
