使用方式xml

android:layout_height="220dp"
paper:sherderBgColor="#f4c600"

paper:sherderTextShadow="false"
paper:sherderTextColor="#99101010"
paper:sherderPaperColor="#dbdbdb"
paper:sherderProgress="false"
/>
java
mPaperShredderView.setShrededType(PaperShredderView.SHREDEDTYPE.Piece);//紙片效果和紙條效果
mPaperShredderView.setSherderProgress(false);
mPaperShredderView.setTitle("清除數(shù)據(jù)");
mPaperShredderView.setTextColor(Color.BLACK);
mPaperShredderView.setPaperColor(Color.BLACK);
mPaperShredderView.setBgColor(Color.WHITE);

如果覺(jué)得還不錯(cuò)撞鹉，去github給我點(diǎn)顆星吧^^
