Android加载动画系列——BlockLoadingAnim
俄罗斯方块，我相信80、90的人肯定玩过，也差不多快被这个时代忘记了，或者说被一些新的玩法替代了，比如：体感俄罗斯方块。今天我们就来实现一款带阴影的方块加载动画~让我们先来看看效果图：
1、BlockLoadingAnim.java源码如下：

2、接着在layout布局文件中使用我们自定义的动画控件
<com.cyril.loadinganim.BlockLoadingAnimandroid:id="@+id/blockloadinganim"android:layout_width="50dp"android:layout_height="50dp"/>
3、然后在Activity中实现动画的播放和停止，使用事例如下：
blockLoadingAnim=(BlockLoadingAnim)findViewById(R.id.blockloadinganim);blockLoadingAnim.isShadow(true);blockLoadingAnim.startAnim();
我们可以通过isShadow(false)方法来关闭底部阴影的效果。
