| * Information for generating a widget to handle classified text. |
| * |
| * <p>A TextClassification object contains icons, labels, onClickListeners and intents that may |
| * be used to build a widget that can be used to act on classified text. There is the concept of a |
| * <i>primary action</i> and other <i>secondary actions</i>. |
| * |
| * <p>e.g. building a view that, when clicked, shares the classified text with the preferred app: |
| * |
| * <pre>{@code |
| * // Called preferably outside the UiThread. |
| * TextClassification classification = textClassifier.classifyText(allText, 10, 25); |
| * |
| * // Called on the UiThread. |
| * Button button = new Button(context); |
| * button.setCompoundDrawablesWithIntrinsicBounds(classification.getIcon(), null, null, null); |
| * button.setText(classification.getLabel()); |
| * button.setOnClickListener(v -> context.startActivity(classification.getIntent())); |
| * }</pre> |
| * |
| * <p>e.g. starting an action mode with menu items that can handle the classified text: |
| * |
| * <pre>{@code |
| * // Called preferably outside the UiThread. |
| * final TextClassification classification = textClassifier.classifyText(allText, 10, 25); |
| * |
| * // Called on the UiThread. |
| * view.startActionMode(new ActionMode.Callback() { |
| * |
| * public boolean onCreateActionMode(ActionMode mode, Menu menu) { |
| * for (int i = 0; i < classification.getActions().size(); ++i) { |
| * RemoteAction action = classification.getActions().get(i); |
| * menu.add(Menu.NONE, i, 20, action.getTitle()) |
| * .setIcon(action.getIcon()); |
| * } |
| * return true; |
| * } |
| * |
| * public boolean onActionItemClicked(ActionMode mode, MenuItem item) { |
| * classification.getActions().get(item.getItemId()).getActionIntent().send(); |
| * return true; |
| * } |
| * |
| * ... |
