Android 时间轴功能，可折叠展开内容的Android时间线，三人行技术开发团队，遍历所有group,将所有项设置成默认展开，将时间轴分为一级和二级状态，可折叠隐藏掉二级内容，时间轴整体效果如测试截图所示，时间线的具体定义和内容如下所示：
String[] strArray = new String[]{"贷款", "更名", "交接"};
String[] str1 = new String[]{"经理送件", "银行送件审核", "银行评估", "买卖双方签约"};
String[] str2 = new String[]{"更名", "划首付", "买方取产权证", "物业维修基金更名", "土地证更名"};
String[] str3 = new String[]{"买方到银行抵押手续", "买方取他向权利证", "银行给卖方划尾款", "全部办结"};
String[] timeStr1 = new String[]{"2013-11-02 13:16:22", "2013-11-02 13:16:22", "2013-11-02 13:16:22", "2013-11-02 13:16:22"};
String[] timeStr2 = new String[]{"2013-11-02 13:16:22", "2013-11-02 13:16:22", "", "", ""};
String[] timeStr3 = new String[]{"", "", "", ""};
