java
mPaperShredderView.setShrededType(PaperShredderView.SHREDEDTYPE.Piece);//纸片效果和纸条效果 mPaperShredderView.setSherderProgress(false); mPaperShredderView.setTitle("清除数据"); mPaperShredderView.setTextColor(Color.BLACK); mPaperShredderView.setPaperColor(Color.BLACK); mPaperShredderView.setBgColor(Color.WHITE); mPaperShredderView.setTextShadow(false); mPaperShredderView.setPaperEnterColor(Color.BLACK); mPaperShredderView.startAnim(1000); mPaperShredderView.stopAnim();如果觉得还不错，去github给我点颗星吧^^
