Android-多个listview层叠显示,被隐藏的listview切换为显示时不显示数据

Question

界面上有三个PullToRefreshListView,呈tab切换样式,
一个显示,其余两个隐藏,我在oncreate中查询数据,并把结果给到adapter中绑定到listview里,结果只有初始为显示的listview会呈现数据,其他的没有数据,而且我在代码中把第二个切换为显示时,接着再重新绑定次数据还是不行.

刚刚发现了一个可行的方法,
初始布局中三个listview设置为显示,oncreate中使用代码设置其余两个为隐藏,点击tab隐藏第一项显示第二项时,调用Adapter的.notifyDataSetChanged();
还有可能会出现adapter为null的现象,需要作检查.
