错误分析

• 确保Adapter的数据更新后一定要调用notifyDataSetChanged()方法通知ListView
• 数据更新和notifyDataSetChanged()放在UI线程内，且必须同步顺序执行，不可异步
• 仔细检查确认getCount()方法返回值是否正确

容错处理

//重写ListView （如果上述方案还未解决则选择该容错机制，否则不推荐）
@Override
protected void layoutChildren() {
    try {
        super.layoutChildren();
    } catch (IllegalStateException e) {
        Log.e("TestDemo", "SlideItemListView item count not equal notificationAdapter.getCount()");
        ((ListAdapter)getAdapter()).notifyDataSetChanged();
    }
}
