使用方式xml

android:layout_width="200dp"

android:layout_height="220dp"
paper:sherderBgColor="#f4c600"
paper:sherderText="清理中"
paper:sherderType="0"
paper:sherderPaperEnterColor="#56abe4"
paper:sherderTextShadow="false"
paper:sherderTextColor="#99101010"
paper:sherderPaperColor="#dbdbdb"
paper:sherderProgress="false"
/>
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();
