为什么Android Studio无法找到资源？

Question

我遵循了本教程：http://imperialsoup.com/2016/04/29/simple-ocr-android-app-using-tesseract-tutorial/ 我的png图像有问题：

Answer 1

删除

tools:context=".MainAcivity"

源路径应该是这样的

android:src="@drawable/test_image"

Answer 2

1. chnage tools:context="com.test.ocr.ocrtest.MainAcivity"

2. 从android:src="@drawable/test_image"

删除/

Answer 3

请使用下一个代码示例来解决问题：

tools:context=".MainAcivity"
should correct as
tools:context="com.example.Acountname.ProjectName.MainActivity"
(find your package name & include before ".MainActivity")

android:src="@/drawable/test_image"
should correct as
android:src="@drawable/test_image"
(remove "/" from "@/drawable")
