- 使用DialogFragment的坑
- Fatal Exception:java.lang.illega
- DialogFragment show() IllegalSta
- OkHttp 报java.lang.IllegalStateEx

- Fragment 中 View 状态保存与恢复源码分析
- android DialogFragment 的show()的问
这样会出错，因为onSaveInstanceState方法是在该Activity即将被销毁前调用，来保存Activity数据的，如果在保存玩状态后再给它添加Fragment就会出错。解决办法就是把commit()方法替换成 commitAllowingStateLoss()就行了
```
CustomFragmentDialog voucherFragmentDialog = ustomFragmentDialog.newInstance(sourceType);
FragmentTransaction fragmentTransaction = getSupportFragmentManager().beginTransaction();
fragmentTransaction.add(voucherFragmentDialog,VoucherFragmentDialog.class.getName());
fragmentTransaction.commitAllowingStateLoss();
```
