我正在我的应用程序中使用案例视图。但是因为我使用长文本，所以不显示“取消”文本。
因为我在一个大的编辑文本上使用了它，所以它里面的圆的半径增加了，并不是所有的文本都能放进去。

ShowcaseConfig config =new ShowcaseConfig();
        config.setDelay(500);
        MaterialShowcaseSequence sequence =new MaterialShowcaseSequence(AddSupportActivity.this, SHOWCASE_ID);

        sequence.setConfig(config);

        sequence.addSequenceItem(mEdtDevName,
                "You can enter the identifier of each supporter here There is nothing wrong with not filling in this field", "GOT IT");

        sequence.addSequenceItem(mEdtProName,
                "Each supporter can have a number of projects in a specific time period.Note: A project has only one supporter at a given time period", "GOT IT");

        sequence.start();

更新：添加以下行可解决此问题：

config.shapePadding = 50
