 /**
- * The {@link UiTranslationManager} class provides ways for apps to use the ui translation
+ * <p>The {@link UiTranslationManager} class provides ways for apps to use the ui translation
  * function in framework.
+ *
+ * <p> The UI translation provides ways for apps to support inline translation for the views. For
+ * example the system supports text translation for {@link TextView}. To support UI translation for
+ * your views, you should override the following methods to provide the content to be translated
+ * and deal with the translated result. Here is an example for {@link TextView}-like views:
+ *
+ * <pre><code>
+ * public class MyTextView extends View {
+ *     public MyTextView(...) {
+ *         // implements how to show the translated result in your View in
+ *         // ViewTranslationCallback and set it by setViewTranslationCallback()
+ *         setViewTranslationCallback(new MyViewTranslationCallback());
+ *     }
+ *
+ *     public void onCreateViewTranslationRequest(int[] supportedFormats,
+ *             Consumer<ViewTranslationRequest> requestsCollector) {
+ *        // collect the information that needs to be translated
+ *        ViewTranslationRequest.Builder requestBuilder =
+ *                     new ViewTranslationRequest.Builder(getAutofillId());
+ *        requestBuilder.setValue(ViewTranslationRequest.ID_TEXT,
+ *                         TranslationRequestValue.forText(etText()));
+ *        requestsCollector.accept(requestBuilder.build());
+ *     }
+ *
+ *     public void onProvideContentCaptureStructure(
+ *             ViewStructure structure, int flags) {
+ *         // set ViewTranslationResponse
+ *         super.onViewTranslationResponse(response);
+ *     }
+ * }
+ * </code></pre>
+ *
+ * <p>If your view provides its own virtual hierarchy (for example, if it's a browser that draws the
+ * HTML using {@link android.graphics.Canvas} or native libraries in a different render process),
+ * you must override {@link View#onCreateVirtualViewTranslationRequests(long[], int[], Consumer)} to
+ * provide the content to be translated and implement
+ * {@link View#onVirtualViewTranslationResponses(android.util.LongSparseArray)} for the translated
+ * result. You also need to implement {@link android.view.translation.ViewTranslationCallback} to
+ * handle the translated information show or hide in your {@link View}.
