您可以使用嵌入在...中的以下代码解析活动类中的数据
代码
// XML parsing data types and nodes
// All static variables
static final String URL = "your XML data path";
// XML node keys
static final String KEY_ITEM = "item"; // parent node(to check every nodes)
static final String TAG1 = "busy";
static final String TAG2 = "and"; // etc
