Remarks

Information for generating a widget to handle classified text.

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 primary action and other secondary actions.

e.g. building a view that, when clicked, shares the classified text with the preferred app:

{@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 -> classification.getActions().get(0).getActionIntent().send());
            }

e.g. starting an action mode with menu items that can handle the classified text:

{@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;
                  }

                  ...
              });
            }
