Annotation Type Implements

@Documented
 @Retention(value=RUNTIME)
 @Target(value=TYPE)
public @interface Implements

Indicates that a class declaration is intended to shadow an Android class declaration. The Robolectric runtime searches classes with this annotation for methods with the Implementation annotation and calls them in place of the methods on the Android class.

Optional Element Summary

Optional Elements

Modifier and Type	Optional Element and Description
boolean	callThroughByDefault If true, Robolectric will invoke the actual Android code for any method that isn’t shadowed.
String	className Android class name (if the Class object is not accessible).
boolean	isInAndroidSdk Denotes that this type exists in the public Android SDK.
boolean	looseSignatures If true, when an exact method signature match isn’t found, Robolectric will look for a method with the same name but with all argument types replaced with java.lang.Object.
int	maxSdk If specified, the shadow class will be applied only for this SDK or lesser.
int	minSdk If specified, the shadow class will be applied only for this SDK or greater.
Class<? extends ShadowPicker<?>>	shadowPicker If specified, the picker will be instantiated and called from within the newly-created Robolectric classloader.
Class<?>	value The Android class to be shadowed.

Element Detail

value

public abstract Class<?> value

The Android class to be shadowed.

Returns:

Android class to shadow.

Default:

void.class

className

public abstract String className

Android class name (if the Class object is not accessible).

Returns:

Android class name.

Default:

""

isInAndroidSdk

public abstract boolean isInAndroidSdk

Denotes that this type exists in the public Android SDK. When this value is true, the annotation processor will generate a shadowOf method.

Returns:

True if the type is exposed in the Android SDK.

Default:

true

callThroughByDefault

public abstract boolean callThroughByDefault

If true, Robolectric will invoke the actual Android code for any method that isn’t shadowed.

Returns:

True to invoke the underlying method.

Default:

true

looseSignatures

public abstract boolean looseSignatures

If true, when an exact method signature match isn’t found, Robolectric will look for a method with the same name but with all argument types replaced with java.lang.Object.

Returns:

True to disable strict signature matching.

Default:

false

minSdk

public abstract int minSdk

If specified, the shadow class will be applied only for this SDK or greater.

Default:

-1

maxSdk

public abstract int maxSdk

If specified, the shadow class will be applied only for this SDK or lesser.

Default:

-1

shadowPicker

public abstract Class<? extends ShadowPicker<?>> shadowPicker

If specified, the picker will be instantiated and called from within the newly-created Robolectric classloader. All shadow classes implementing the same Android class must use the same ShadowPicker.

Default:

org.robolectric.annotation.Implements.DefaultShadowPicker.class
