我正在Android工作室创建我的第一个Robolectric测试，但会弹出下一个错误：
android.content.res.Resources $ NotFoundException：无法找到 资源ID＃0x7f040019
我已经尝试了好几件事。清理，重建和重新加载项目。我检查了我的资源，包括＆＃39; activity_main.xml＆＃39;。无论我使用什么活动，错误都发生在下一行：
setContentView(R.layout.activity_main);
完整错误：

@RunWith(RobolectricTestRunner.class)
public class RoboTest {
@Test
public void testRoboTest()

EditText editText = (EditText)activity.findViewById(R.id.editText);
assertThat(editText.getText().toString(), equalTo("TEST"));
}
}
有谁知道如何修复此错误？
答案 0 :(得分：0)
将此添加到click方法
之外EditText editText = (EditText)findViewById(R.id.editText);
根据你的代码findViewById获取本地视图内容（在按钮内）。里面没有EditText。

将RoboTest.java中的@RunWith（RobolectricTestRunner.class）更改为@RunWith（RobolectricGradleTestRunner.class）帮助了我！
