问Android执行longClick而不是单击

EN

/**
   * Returns an action that performs a single click on the view.
   *
   * If the click takes longer than the 'long press' duration (which is possible) the provided
   * rollback action is invoked on the view and a click is attempted again.
   *
   * This is only necessary if the view being clicked on has some different behaviour for long press
   * versus a normal tap.
   *
   * For example - if a long press on a particular view element opens a popup menu -
   * ViewActions.pressBack() may be an acceptable rollback action.
   *
   * <br>
   * View constraints:
   * <ul>
   * <li>must be displayed on screen</li>
   * <li>any constraints of the rollbackAction</li>
   * <ul>
