我已经在StackOverflow上研究了这个错误并尝试了所有的建议，但仍然有错误 . 应用程序尝试加载，我可以看到几个警报背后的主屏幕和应用程序关闭的错误 .
我试过的事情：
-
加入清单 -
-
in
MainActivity，确保我使用“this”代替其他参考文献 -
添加到
AlertDialog-
dialog.getWindow().setType(WindowManager.LayoutParams.TYPE_SYSTEM_ALERT);
注意：我还在 setContentView(R.layout.activity_main); 之后的 MainActivity 中注释掉了所有内容，但仍然有错误 . 我怀疑这个问题与我如何使用我的片段和tjerk直接相关 . ActionSlideExpandableListView 菜单 .
