使用ExpandableListView实现时间轴效果

标签：android   blog   http   java   使用   os   io   for   

不废话，先上图，看看效果

这是用ExpandableListView来实现时间轴效果，原理比较简单，以月份为第一级，以天为第二级来实现的。

	private static final String TAG = "haijiang";
	private List<OneStatusEntity> oneList;
	private ExpandableListView expandlistView;
	private StatusExpandAdapter statusAdapter;
	private Context context;

	@Override
	public void onCreate(Bundle savedInstanceState) {
		super.onCreate(savedInstanceState);
		setContentView(R.layout.main);
		context = this;
		expandlistView = (ExpandableListView) findViewById(R.id.expandlist);
		
		putInitData();
		
		statusAdapter = new StatusExpandAdapter(context, oneList);
		expandlistView.setAdapter(statusAdapter);
		expandlistView.setGroupIndicator(null); // 去掉默认带的箭头

		// 遍历所有group,将所有项设置成默认展开
		int groupCount = expandlistView.getCount();
		for (int i = 0; i < groupCount; i++) {
			expandlistView.expandGroup(i);
		}
		expandlistView.setOnGroupClickListener(new OnGroupClickListener() {

			@Override
			public boolean onGroupClick(ExpandableListView parent, View v, int groupPosition, long id) {
				// TODO Auto-generated method stub
