您在NullPointerException上有一个169。不知道是什么线......

我们知道你在这段代码中：

Uri selectimage=intent.getData();
Log.d("take","pic");
img1.setImageURI(selectimage);

因为您的ResultInfo显示request=2, result=-1。这意味着你的空指针在那里。

最可能的原因是img1为空。我看到你在上面使用它，但不知道它是否在以后的范围内。在不知道如何或何时初始化的情况下，很难说。

这里没有其他可能发生的事情。唯一的另一种可能性是intent为空，但我不太重视。您的ResultInfo清楚地显示了回复的意图。

将来，您可以在logcat中自己找到这些东西。只需寻找类似的东西：

Caused by: java.lang.NullPointerException
    at com.inspectreport6784.NewInspection.onActivityResult(NewInspection.java:169)

对于简单的空指针，它很容易缩小范围。它为您提供文件，类，方法和行。
