請確保您的ShowCaseView類有靜態類ConfigOptions

public static class ConfigOptions { 

    public boolean block = true, noButton = false; 
    public boolean hideOnClickOutside = false; 

    /** 
    * Does not work with the {@link ShowcaseViews} class as it does not make sense (only with 
    * {@link ShowcaseView}). 
    * @deprecated not compatible with Target API 
    */ 
    @Deprecated 
    public int insert = INSERT_TO_DECOR; 

    /** 
    * If you want to use more than one Showcase with the {@link ConfigOptions#shotType} {@link 
    * ShowcaseView#TYPE_ONE_SHOT} in one Activity, set a unique value for every different 
    * Showcase you want to use. 
    */ 
    public int showcaseId = 0; 

    /** 
    * If you want to use more than one Showcase with {@link ShowcaseView#TYPE_ONE_SHOT} in one 
    * Activity, set a unique {@link ConfigOptions#showcaseId} value for every different 
    * Showcase you want to use. If you want to use this in the {@link ShowcaseViews} class, you 
    * need to set a custom showcaseId for each {@link ShowcaseView}. 
    */ 
    public int shotType = TYPE_NO_LIMIT; 

    /** 
    * Default duration for fade in animation. Set to 0 to disable. 
    */ 
    public int fadeInDuration = AnimationUtils.DEFAULT_DURATION; 

    /** 
    * Default duration for fade out animation. Set to 0 to disable. 
    */ 
    public int fadeOutDuration = AnimationUtils.DEFAULT_DURATION; 
    /** 
    * Allow custom positioning of the button within the showcase view. 
    */ 
    public LayoutParams buttonLayoutParams = null; 

    /** 
    * Whether the text should be centered or stretched in the available space 
    */ 
    public boolean centerText = false; 
}
