取消后，startActivityForResult中的startActivityForResult返回mainActivity

标签： android android-intent android-activity

如果我取消QR码扫描，我有一个它调用startActivityForResult的MainActivity，并且该活动调用startActivityForResult（QR码扫描）。

结束 
protected void onActivityResult(int requestCode, int resultCode, Intent data)

在主活动中不在第一个startActivityForResult中，好像第一个startActivityForResult已经以某种方式退出，如果我扫描代码我在第一个startActivityForResult中正确得到结果

为什么会发生这种情况的任何想法？

在阅读日志时，您似乎尝试在取消扫描时退出ProgressDialog中的Activity。第533行和/或第116行会发生什么？

Here is a similar question。建议您在扫描活动中的dismiss()上致电ProgressDialog。例如，覆盖扫描活动中的onBackPressed()方法并取消任何对话框。
