我使用Robolectric 3.3来测试AppCompatActivity的{{1}}
我得到之后：
com.android.support:appcompat-v7:23.4.0我创建了以下测试运行器：
java.lang.IllegalStateException: You need to use a Theme.AppCompat theme (or descendant) with this activity.
然后我得到了：
public class ActivityTestRunner extends RobolectricTestRunner {
public ActivityTestRunner(Class<?> testClass) throws InitializationError {
super(testClass);
}
@Override
protected AndroidManifest getAppManifest(Config config)
{
return new AppManifest(Fs.fileFromPath(config.manifest()),
Fs.fileFromPath(config.resourceDir()),
Fs.fileFromPath(config.assetDir()));
}
private class AppManifest extends AndroidManifest
{
private static final String THEME = "@style/Theme.AppCompat";
public AppManifest(FsFile androidManifestFile, FsFile resDirectory, FsFile assetsDirectory) {
super(androidManifestFile, resDirectory, assetsDirectory);
}
public AppManifest(FsFile androidManifestFile, FsFile resDirectory, FsFile assetsDirectory, String overridePackageName) {
super(androidManifestFile, resDirectory, assetsDirectory, overridePackageName);
}
@Override
public String getThemeRef() {
return THEME;
}
@Override
public String getThemeRef(String activityClassName) {
return THEME;
}
}
}
样式：

如何使其有效？
答案 0 :(得分：2)
只需移除自定义运行器并修复 Robolectric 测试的路径。检查如何操作here。
答案 1 :(得分：2)
对我来说，解决问题的方法是将以下内容添加到我的应用程序gradle文件
android {
//OTHER CONFIG
testOptions {
unitTests {
includeAndroidResources = true
}
}
}
答案 2 :(得分：1)
问题在于我没有添加@Config(constants = BuildConfig.class)
哪个必须添加到tutorial
答案 3 :(得分：-2)
您遇到此问题的原因是您尝试应用对话框主题的活动是扩展ActionBarActivity，这需要应用AppCompat主题。
更新：扩展AppCompatActivity也会出现此问题
在这种情况下，将Java继承从ActionBarActivity更改为Activity，并将对话框主题原样保留在清单中，非Theme.AppCompat值
一般规则是，如果您希望代码支持旧版本的Android，则应该具有AppCompat主题，而Java代码应该扩展AppCompatActivity。如果你有一个不需要这种支持的活动，比如你只关心Android的最新版本和功能，你可以应用任何主题，但是java代码必须扩展普通的旧活动。
注意：当从AppCompatActivity（或子类，ActionBarActivity）更改为Activity时，还必须将具有“support”的各种调用更改为没有“support”的相应调用。因此，不要使用getSupportFragmentManager，而是调用getFragmentManager。
