Description
| Interface Summary | |
|---|---|
| ProgressIndicatorListener | Listener interface for processing notifications of changes in the data model of a progress. |
| Class Summary | |
|---|---|
| AbstractProgressIndicatorController | This class acts as a controller for an AbstractProgressIndicatorView
based on the Model-View-Controller design pattern. |
| AbstractProgressIndicatorModel | This model represents the data related to the progress being indicated. |
| AbstractProgressIndicatorView | This manager presents an animating field to the user to indicate the progress of work being done by an application. |
| ActivityImageField | This field loops an animation that represents the progress of a task. |
| ActivityIndicatorController | Implementation of AbstractProgressIndicatorController. |
| ActivityIndicatorModel | Implementation of AbstractProgressIndicatorModel. |
| ActivityIndicatorView | Implementation of AbstractProgressIndicatorView that is used for
representing progress where the duration is unknown. |
| ProgressBarField | Represents the progress of a task that can be expressed with respect to a set of values. |
| ProgressIndicatorController | Implementation of AbstractProgressIndicatorController. |
| ProgressIndicatorModel | Implementation of AbstractProgressIndicatorModel. |
| ProgressIndicatorView | Implementation of AbstractProgressIndicatorView that is used for
representing progress where there is a numeric representation for the work being done. |
The Activity and Progress Indicator API allows you to display visual cues on a screen to indicate that work is being done or that a task is proceeding. The API uses a model-view-controller design pattern. You can represent an activity whose duration is unknown, as well as progress that can be represented numerically, for example, as a percentage of a completed task.
The API includes two fields that are responsible for rendering the activity or progress:
ActivityImageField represents activity by using a bitmap that contains frames of an animation. The displayed frame changes over time. This field is built and set by ActivityIndicatorView. ProgressBarField represents the progress of a task as a bar that fills as the task completes. This field is built and set by ProgressIndicatorView. For an example of how to use this API, see the Progress Indicator Demo sample application.
