閒的蛋疼嘗試了一下，做了如下的效果

直接扔程式碼

wxml部分：

 <view class="cash-out bubble">提現</view>
 <view class="share bubble">推薦</view>

wxss部分：

.cash-out,.share{
  width: 325rpx;
  height: 80rpx;
  background: #333;
  border-radius: 6rpx;
  font-size: 30rpx;
  color: #fff;
  line-height: 80rpx;
  text-align: center;
}
.bubble{  
  position: relative;
  overflow: hidden;
}
.bubble:after{
  content: "";
  background: #999;
  position: absolute; 
  width: 750rpx;
  height: 750rpx;
  left: calc(50% - 375rpx);
  top: calc(50% - 375rpx);
  opacity: 0;
  margin: auto;
  border-radius: 50%;
  transform: scale(1);
  transition: all 0.5s ease-in-out;
}
.bubble:active:after {
  transform: scale(0);
  opacity: 1;
  transition: 0s;
}
