Annotation Type Implements


@Documented
@Retention(RUNTIME)
@Target(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 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 Details

    • value

      Class<?> value
      The Android class to be shadowed.
      Returns:
      Android class to shadow.
      Default:
      void.class
    • className

      String className
      Android class name (if the Class object is not accessible).
      Returns:
      Android class name.
      Default:
      ""
    • isInAndroidSdk

      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

      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

      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

      int minSdk
      If specified, the shadow class will be applied only for this SDK or greater.
      Default:
      -1
    • maxSdk

      int maxSdk
      If specified, the shadow class will be applied only for this SDK or lesser.
      Default:
      -1
    • shadowPicker

      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
