我的应用程序有很多屏幕和视图,从这个跟踪没有框架来自我的应用程序:(我如何找出从哪里开始寻找？任何指针对此非常赞赏.

解决方法 覆盖getheadersCount()并在数据大小为0时始终返回0.

@OverrIDepublic int getheadersCount(){  return getCount() == 0 ? 0 : super.getheaderCount();}

当您具有非空数据列表并且它尝试访问0元素时会发生这种情况.

您也可能需要对isEnabled()方法执行相同的 *** 作

@OverrIDepublic boolean isEnabled(int position){  return position > 0 || getheadersCount() > 0 ? super.isEnabled(position) : false;}
