Android 仿日历翻页、仿htc时钟翻页、数字翻页切换效果

//获取输入框中的数字
  int newNumber = Integer.parseInt(etInput.getText().toString());
  //获取个、十、百位数字
  int nbai = newNumber / 100;
  int nshi = newNumber % 100 / 10;
  int nge = newNumber % 10;
  //获取上次数字的个、十、百位数字
  int obai = oldNumber / 100;
  int oshi = oldNumber % 100 / 10;
  int oge = oldNumber % 10;
  //把当前的数字记录下来
  oldNumber = newNumber;
  //获取新数字与旧数字的个、十、百相差的数字
  int bai = nbai + 10 - obai;
  int shi = nshi + 10 - oshi;
  int ge = nge + 10 - oge;
  //如果值大于9，就减去10
  if(bai > 9){
   bai = bai - 10;
  }
  if(shi > 9){
   shi = shi - 10;
  }
  if(ge > 9){
   ge = ge - 10;
  }
  //把需要切换几次设置到自定义控件上
  bitflip1.smoothFlip(bai, false);
  bitflip2.smoothFlip(shi, false);
  bitflip3.smoothFlip(ge, false);
