你有NullPointerException在線169。不知道是什麼行是...

我們知道你的代碼塊是：

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

因爲你ResultInfo顯示request=2, result=-1。這意味着你的空指針在那裏。

最可能的原因是img1爲空。我看到你在上面使用它，但是它在後面的範圍內是未知的。不知道如何或何時初始化，很難說。

這裏沒有太多可以發生的事情。唯一的另一種可能性是intent爲空，但我不算太多。你的ResultInfo清楚地顯示回來的意圖。

未來，您可以自己在logcat中找到這些東西。只要尋找類似：

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

對於簡單的空指針，它很容易縮小。它爲您提供文件，類，方法和行。
